what is a thesis proof essay

While Sandel argues that pursuing perfection through genetic engineering would decrease our sense of humility, he claims that the sense of solidarity we would lose is also important.

This thesis summarizes several points in Sandel’s argument, but it does not make a claim about how we should understand his argument. A reader who read Sandel’s argument would not also need to read an essay based on this descriptive thesis.  

Broad thesis (arguable, but difficult to support with evidence) 

Michael Sandel’s arguments about genetic engineering do not take into consideration all the relevant issues.

This is an arguable claim because it would be possible to argue against it by saying that Michael Sandel’s arguments do take all of the relevant issues into consideration. But the claim is too broad. Because the thesis does not specify which “issues” it is focused on—or why it matters if they are considered—readers won’t know what the rest of the essay will argue, and the writer won’t know what to focus on. If there is a particular issue that Sandel does not address, then a more specific version of the thesis would include that issue—hand an explanation of why it is important.  

Arguable thesis with analytical claim 

While Sandel argues persuasively that our instinct to “remake” (54) ourselves into something ever more perfect is a problem, his belief that we can always draw a line between what is medically necessary and what makes us simply “better than well” (51) is less convincing.

This is an arguable analytical claim. To argue for this claim, the essay writer will need to show how evidence from the article itself points to this interpretation. It’s also a reasonable scope for a thesis because it can be supported with evidence available in the text and is neither too broad nor too narrow.  

Arguable thesis with normative claim 

Given Sandel’s argument against genetic enhancement, we should not allow parents to decide on using Human Growth Hormone for their children.

This thesis tells us what we should do about a particular issue discussed in Sandel’s article, but it does not tell us how we should understand Sandel’s argument.  

Questions to ask about your thesis 

• Is the thesis truly arguable? Does it speak to a genuine dilemma in the source, or would most readers automatically agree with it?  
• Is the thesis too obvious? Again, would most or all readers agree with it without needing to see your argument?  
• Is the thesis complex enough to require a whole essay's worth of argument?  
• Is the thesis supportable with evidence from the text rather than with generalizations or outside research?  
• Would anyone want to read a paper in which this thesis was developed? That is, can you explain what this paper is adding to our understanding of a problem, question, or topic?

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

• tells the reader how you will interpret the significance of the subject matter under discussion.
• is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
• directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
• makes a claim that others might dispute.
• is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

• Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
• Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
• Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
• Does my thesis pass the “So what?” test? If a reader’s first response is likely to  be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
• Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
• Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

• Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
• Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
• Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
• Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
• Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

• Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.

• Do I answer the question? Yes!
• Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
• Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
• Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
• Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.

Developing a Thesis Statement

Many papers you write require developing a thesis statement. In this section you’ll learn what a thesis statement is and how to write one.

Keep in mind that not all papers require thesis statements . If in doubt, please consult your instructor for assistance.

What is a thesis statement?

A thesis statement . . .

• Makes an argumentative assertion about a topic; it states the conclusions that you have reached about your topic.
• Makes a promise to the reader about the scope, purpose, and direction of your paper.
• Is focused and specific enough to be “proven” within the boundaries of your paper.
• Is generally located near the end of the introduction ; sometimes, in a long paper, the thesis will be expressed in several sentences or in an entire paragraph.
• Identifies the relationships between the pieces of evidence that you are using to support your argument.

Not all papers require thesis statements! Ask your instructor if you’re in doubt whether you need one.

Identify a topic

Your topic is the subject about which you will write. Your assignment may suggest several ways of looking at a topic; or it may name a fairly general concept that you will explore or analyze in your paper.

Consider what your assignment asks you to do

Inform yourself about your topic, focus on one aspect of your topic, ask yourself whether your topic is worthy of your efforts, generate a topic from an assignment.

Below are some possible topics based on sample assignments.

Sample assignment 1

Analyze Spain’s neutrality in World War II.

Identified topic

Franco’s role in the diplomatic relationships between the Allies and the Axis

This topic avoids generalities such as “Spain” and “World War II,” addressing instead on Franco’s role (a specific aspect of “Spain”) and the diplomatic relations between the Allies and Axis (a specific aspect of World War II).

Sample assignment 2

Analyze one of Homer’s epic similes in the Iliad.

The relationship between the portrayal of warfare and the epic simile about Simoisius at 4.547-64.

This topic focuses on a single simile and relates it to a single aspect of the Iliad ( warfare being a major theme in that work).

Developing a Thesis Statement–Additional information

Your assignment may suggest several ways of looking at a topic, or it may name a fairly general concept that you will explore or analyze in your paper. You’ll want to read your assignment carefully, looking for key terms that you can use to focus your topic.

Sample assignment: Analyze Spain’s neutrality in World War II Key terms: analyze, Spain’s neutrality, World War II

After you’ve identified the key words in your topic, the next step is to read about them in several sources, or generate as much information as possible through an analysis of your topic. Obviously, the more material or knowledge you have, the more possibilities will be available for a strong argument. For the sample assignment above, you’ll want to look at books and articles on World War II in general, and Spain’s neutrality in particular.

As you consider your options, you must decide to focus on one aspect of your topic. This means that you cannot include everything you’ve learned about your topic, nor should you go off in several directions. If you end up covering too many different aspects of a topic, your paper will sprawl and be unconvincing in its argument, and it most likely will not fulfull the assignment requirements.

For the sample assignment above, both Spain’s neutrality and World War II are topics far too broad to explore in a paper. You may instead decide to focus on Franco’s role in the diplomatic relationships between the Allies and the Axis , which narrows down what aspects of Spain’s neutrality and World War II you want to discuss, as well as establishes a specific link between those two aspects.

Before you go too far, however, ask yourself whether your topic is worthy of your efforts. Try to avoid topics that already have too much written about them (i.e., “eating disorders and body image among adolescent women”) or that simply are not important (i.e. “why I like ice cream”). These topics may lead to a thesis that is either dry fact or a weird claim that cannot be supported. A good thesis falls somewhere between the two extremes. To arrive at this point, ask yourself what is new, interesting, contestable, or controversial about your topic.

As you work on your thesis, remember to keep the rest of your paper in mind at all times . Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Derive a main point from topic

Once you have a topic, you will have to decide what the main point of your paper will be. This point, the “controlling idea,” becomes the core of your argument (thesis statement) and it is the unifying idea to which you will relate all your sub-theses. You can then turn this “controlling idea” into a purpose statement about what you intend to do in your paper.

Look for patterns in your evidence

Compose a purpose statement.

Consult the examples below for suggestions on how to look for patterns in your evidence and construct a purpose statement.

• Franco first tried to negotiate with the Axis
• Franco turned to the Allies when he couldn’t get some concessions that he wanted from the Axis

Possible conclusion:

Spain’s neutrality in WWII occurred for an entirely personal reason: Franco’s desire to preserve his own (and Spain’s) power.

Purpose statement

This paper will analyze Franco’s diplomacy during World War II to see how it contributed to Spain’s neutrality.

• The simile compares Simoisius to a tree, which is a peaceful, natural image.
• The tree in the simile is chopped down to make wheels for a chariot, which is an object used in warfare.

At first, the simile seems to take the reader away from the world of warfare, but we end up back in that world by the end.

This paper will analyze the way the simile about Simoisius at 4.547-64 moves in and out of the world of warfare.

Derive purpose statement from topic

To find out what your “controlling idea” is, you have to examine and evaluate your evidence . As you consider your evidence, you may notice patterns emerging, data repeated in more than one source, or facts that favor one view more than another. These patterns or data may then lead you to some conclusions about your topic and suggest that you can successfully argue for one idea better than another.

For instance, you might find out that Franco first tried to negotiate with the Axis, but when he couldn’t get some concessions that he wanted from them, he turned to the Allies. As you read more about Franco’s decisions, you may conclude that Spain’s neutrality in WWII occurred for an entirely personal reason: his desire to preserve his own (and Spain’s) power. Based on this conclusion, you can then write a trial thesis statement to help you decide what material belongs in your paper.

Sometimes you won’t be able to find a focus or identify your “spin” or specific argument immediately. Like some writers, you might begin with a purpose statement just to get yourself going. A purpose statement is one or more sentences that announce your topic and indicate the structure of the paper but do not state the conclusions you have drawn . Thus, you might begin with something like this:

• This paper will look at modern language to see if it reflects male dominance or female oppression.
• I plan to analyze anger and derision in offensive language to see if they represent a challenge of society’s authority.

At some point, you can turn a purpose statement into a thesis statement. As you think and write about your topic, you can restrict, clarify, and refine your argument, crafting your thesis statement to reflect your thinking.

As you work on your thesis, remember to keep the rest of your paper in mind at all times. Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Compose a draft thesis statement

If you are writing a paper that will have an argumentative thesis and are having trouble getting started, the techniques in the table below may help you develop a temporary or “working” thesis statement.

Begin with a purpose statement that you will later turn into a thesis statement.

Assignment: Discuss the history of the Reform Party and explain its influence on the 1990 presidential and Congressional election.

Purpose Statement: This paper briefly sketches the history of the grassroots, conservative, Perot-led Reform Party and analyzes how it influenced the economic and social ideologies of the two mainstream parties.

Question-to-Assertion

If your assignment asks a specific question(s), turn the question(s) into an assertion and give reasons why it is true or reasons for your opinion.

Assignment : What do Aylmer and Rappaccini have to be proud of? Why aren’t they satisfied with these things? How does pride, as demonstrated in “The Birthmark” and “Rappaccini’s Daughter,” lead to unexpected problems?

Beginning thesis statement: Alymer and Rappaccinni are proud of their great knowledge; however, they are also very greedy and are driven to use their knowledge to alter some aspect of nature as a test of their ability. Evil results when they try to “play God.”

Write a sentence that summarizes the main idea of the essay you plan to write.

Main idea: The reason some toys succeed in the market is that they appeal to the consumers’ sense of the ridiculous and their basic desire to laugh at themselves.

Make a list of the ideas that you want to include; consider the ideas and try to group them.

• nature = peaceful
• war matériel = violent (competes with 1?)
• need for time and space to mourn the dead
• war is inescapable (competes with 3?)

Use a formula to arrive at a working thesis statement (you will revise this later).

• although most readers of _______ have argued that _______, closer examination shows that _______.
• _______ uses _______ and _____ to prove that ________.
• phenomenon x is a result of the combination of __________, __________, and _________.

What to keep in mind as you draft an initial thesis statement

Beginning statements obtained through the methods illustrated above can serve as a framework for planning or drafting your paper, but remember they’re not yet the specific, argumentative thesis you want for the final version of your paper. In fact, in its first stages, a thesis statement usually is ill-formed or rough and serves only as a planning tool.

As you write, you may discover evidence that does not fit your temporary or “working” thesis. Or you may reach deeper insights about your topic as you do more research, and you will find that your thesis statement has to be more complicated to match the evidence that you want to use.

You must be willing to reject or omit some evidence in order to keep your paper cohesive and your reader focused. Or you may have to revise your thesis to match the evidence and insights that you want to discuss. Read your draft carefully, noting the conclusions you have drawn and the major ideas which support or prove those conclusions. These will be the elements of your final thesis statement.

Sometimes you will not be able to identify these elements in your early drafts, but as you consider how your argument is developing and how your evidence supports your main idea, ask yourself, “ What is the main point that I want to prove/discuss? ” and “ How will I convince the reader that this is true? ” When you can answer these questions, then you can begin to refine the thesis statement.

Refine and polish the thesis statement

To get to your final thesis, you’ll need to refine your draft thesis so that it’s specific and arguable.

• Ask if your draft thesis addresses the assignment
• Question each part of your draft thesis
• Clarify vague phrases and assertions
• Investigate alternatives to your draft thesis

Consult the example below for suggestions on how to refine your draft thesis statement.

Sample Assignment

Choose an activity and define it as a symbol of American culture. Your essay should cause the reader to think critically about the society which produces and enjoys that activity.

• Ask The phenomenon of drive-in facilities is an interesting symbol of american culture, and these facilities demonstrate significant characteristics of our society.This statement does not fulfill the assignment because it does not require the reader to think critically about society.

Drive-ins are an interesting symbol of American culture because they represent Americans’ significant creativity and business ingenuity.

Among the types of drive-in facilities familiar during the twentieth century, drive-in movie theaters best represent American creativity, not merely because they were the forerunner of later drive-ins and drive-throughs, but because of their impact on our culture: they changed our relationship to the automobile, changed the way people experienced movies, and changed movie-going into a family activity.

While drive-in facilities such as those at fast-food establishments, banks, pharmacies, and dry cleaners symbolize America’s economic ingenuity, they also have affected our personal standards.

While drive-in facilities such as those at fast- food restaurants, banks, pharmacies, and dry cleaners symbolize (1) Americans’ business ingenuity, they also have contributed (2) to an increasing homogenization of our culture, (3) a willingness to depersonalize relationships with others, and (4) a tendency to sacrifice quality for convenience.

This statement is now specific and fulfills all parts of the assignment. This version, like any good thesis, is not self-evident; its points, 1-4, will have to be proven with evidence in the body of the paper. The numbers in this statement indicate the order in which the points will be presented. Depending on the length of the paper, there could be one paragraph for each numbered item or there could be blocks of paragraph for even pages for each one.

Complete the final thesis statement

The bottom line.

As you move through the process of crafting a thesis, you’ll need to remember four things:

• Context matters! Think about your course materials and lectures. Try to relate your thesis to the ideas your instructor is discussing.
• As you go through the process described in this section, always keep your assignment in mind . You will be more successful when your thesis (and paper) responds to the assignment than if it argues a semi-related idea.
• Your thesis statement should be precise, focused, and contestable ; it should predict the sub-theses or blocks of information that you will use to prove your argument.
• Make sure that you keep the rest of your paper in mind at all times. Change your thesis as your paper evolves, because you do not want your thesis to promise more than your paper actually delivers.

In the beginning, the thesis statement was a tool to help you sharpen your focus, limit material and establish the paper’s purpose. When your paper is finished, however, the thesis statement becomes a tool for your reader. It tells the reader what you have learned about your topic and what evidence led you to your conclusion. It keeps the reader on track–well able to understand and appreciate your argument.

How to Write a Solid Thesis Statement

The important sentence expresses your central assertion or argument

A thesis statement provides the foundation for your entire research paper or essay. This statement is the central assertion that you want to express in your essay. A successful thesis statement is one that is made up of one or two sentences clearly laying out your central idea and expressing an informed, reasoned answer to your research question.

Usually, the thesis statement will appear at the end of the first paragraph of your paper. There are a few different types, and the content of your thesis statement will depend upon the type of paper you’re writing.

Key Takeaways: Writing a Thesis Statement

• A thesis statement gives your reader a preview of your paper's content by laying out your central idea and expressing an informed, reasoned answer to your research question.
• Thesis statements will vary depending on the type of paper you are writing, such as an expository essay, argument paper, or analytical essay.
• Before creating a thesis statement, determine whether you are defending a stance, giving an overview of an event, object, or process, or analyzing your subject

Expository Essay Thesis Statement Examples

An expository essay "exposes" the reader to a new topic; it informs the reader with details, descriptions, or explanations of a subject. If you are writing an expository essay , your thesis statement should explain to the reader what she will learn in your essay. For example:

• The United States spends more money on its military budget than all the industrialized nations combined.
• Gun-related homicides and suicides are increasing after years of decline.
• Hate crimes have increased three years in a row, according to the FBI.
• Post-traumatic stress disorder (PTSD) increases the risk of stroke and arterial fibrillation (irregular heartbeat).

These statements provide a statement of fact about the topic (not just opinion) but leave the door open for you to elaborate with plenty of details. In an expository essay, you don't need to develop an argument or prove anything; you only need to understand your topic and present it in a logical manner. A good thesis statement in an expository essay always leaves the reader wanting more details.

Types of Thesis Statements

Before creating a thesis statement, it's important to ask a few basic questions, which will help you determine the kind of essay or paper you plan to create:

• Are you defending a stance in a controversial essay ?
• Are you simply giving an overview or describing an event, object, or process?
• Are you conducting an analysis of an event, object, or process?

In every thesis statement , you will give the reader a preview of your paper's content, but the message will differ a little depending on the essay type .

Argument Thesis Statement Examples

If you have been instructed to take a stance on one side of a controversial issue, you will need to write an argument essay . Your thesis statement should express the stance you are taking and may give the reader a preview or a hint of your evidence. The thesis of an argument essay could look something like the following:

• Self-driving cars are too dangerous and should be banned from the roadways.
• The exploration of outer space is a waste of money; instead, funds should go toward solving issues on Earth, such as poverty, hunger, global warming, and traffic congestion.
• The U.S. must crack down on illegal immigration.
• Street cameras and street-view maps have led to a total loss of privacy in the United States and elsewhere.

These thesis statements are effective because they offer opinions that can be supported by evidence. If you are writing an argument essay, you can craft your own thesis around the structure of the statements above.

Analytical Essay Thesis Statement Examples

In an analytical essay assignment, you will be expected to break down a topic, process, or object in order to observe and analyze your subject piece by piece. Examples of a thesis statement for an analytical essay include:

• The criminal justice reform bill passed by the U.S. Senate in late 2018 (" The First Step Act ") aims to reduce prison sentences that disproportionately fall on nonwhite criminal defendants.
• The rise in populism and nationalism in the U.S. and European democracies has coincided with the decline of moderate and centrist parties that have dominated since WWII.
• Later-start school days increase student success for a variety of reasons.

Because the role of the thesis statement is to state the central message of your entire paper, it is important to revisit (and maybe rewrite) your thesis statement after the paper is written. In fact, it is quite normal for your message to change as you construct your paper.

Writing a Paper: Thesis Statements

Basics of thesis statements.

The thesis statement is the brief articulation of your paper's central argument and purpose. You might hear it referred to as simply a "thesis." Every scholarly paper should have a thesis statement, and strong thesis statements are concise, specific, and arguable. Concise means the thesis is short: perhaps one or two sentences for a shorter paper. Specific means the thesis deals with a narrow and focused topic, appropriate to the paper's length. Arguable means that a scholar in your field could disagree (or perhaps already has!).

Strong thesis statements address specific intellectual questions, have clear positions, and use a structure that reflects the overall structure of the paper. Read on to learn more about constructing a strong thesis statement.

Being Specific

This thesis statement has no specific argument:

Needs Improvement: In this essay, I will examine two scholarly articles to find similarities and differences.

This statement is concise, but it is neither specific nor arguable—a reader might wonder, "Which scholarly articles? What is the topic of this paper? What field is the author writing in?" Additionally, the purpose of the paper—to "examine…to find similarities and differences" is not of a scholarly level. Identifying similarities and differences is a good first step, but strong academic argument goes further, analyzing what those similarities and differences might mean or imply.

Better: In this essay, I will argue that Bowler's (2003) autocratic management style, when coupled with Smith's (2007) theory of social cognition, can reduce the expenses associated with employee turnover.

The new revision here is still concise, as well as specific and arguable.  We can see that it is specific because the writer is mentioning (a) concrete ideas and (b) exact authors.  We can also gather the field (business) and the topic (management and employee turnover). The statement is arguable because the student goes beyond merely comparing; he or she draws conclusions from that comparison ("can reduce the expenses associated with employee turnover").

Making a Unique Argument

This thesis draft repeats the language of the writing prompt without making a unique argument:

Needs Improvement: The purpose of this essay is to monitor, assess, and evaluate an educational program for its strengths and weaknesses. Then, I will provide suggestions for improvement.

You can see here that the student has simply stated the paper's assignment, without articulating specifically how he or she will address it. The student can correct this error simply by phrasing the thesis statement as a specific answer to the assignment prompt.

Better: Through a series of student interviews, I found that Kennedy High School's antibullying program was ineffective. In order to address issues of conflict between students, I argue that Kennedy High School should embrace policies outlined by the California Department of Education (2010).

Words like "ineffective" and "argue" show here that the student has clearly thought through the assignment and analyzed the material; he or she is putting forth a specific and debatable position. The concrete information ("student interviews," "antibullying") further prepares the reader for the body of the paper and demonstrates how the student has addressed the assignment prompt without just restating that language.

Creating a Debate

This thesis statement includes only obvious fact or plot summary instead of argument:

Needs Improvement: Leadership is an important quality in nurse educators.

A good strategy to determine if your thesis statement is too broad (and therefore, not arguable) is to ask yourself, "Would a scholar in my field disagree with this point?" Here, we can see easily that no scholar is likely to argue that leadership is an unimportant quality in nurse educators.  The student needs to come up with a more arguable claim, and probably a narrower one; remember that a short paper needs a more focused topic than a dissertation.

Better: Roderick's (2009) theory of participatory leadership  is particularly appropriate to nurse educators working within the emergency medicine field, where students benefit most from collegial and kinesthetic learning.

Here, the student has identified a particular type of leadership ("participatory leadership"), narrowing the topic, and has made an arguable claim (this type of leadership is "appropriate" to a specific type of nurse educator). Conceivably, a scholar in the nursing field might disagree with this approach. The student's paper can now proceed, providing specific pieces of evidence to support the arguable central claim.

Choosing the Right Words

This thesis statement uses large or scholarly-sounding words that have no real substance:

Needs Improvement: Scholars should work to seize metacognitive outcomes by harnessing discipline-based networks to empower collaborative infrastructures.

There are many words in this sentence that may be buzzwords in the student's field or key terms taken from other texts, but together they do not communicate a clear, specific meaning. Sometimes students think scholarly writing means constructing complex sentences using special language, but actually it's usually a stronger choice to write clear, simple sentences. When in doubt, remember that your ideas should be complex, not your sentence structure.

Better: Ecologists should work to educate the U.S. public on conservation methods by making use of local and national green organizations to create a widespread communication plan.

Notice in the revision that the field is now clear (ecology), and the language has been made much more field-specific ("conservation methods," "green organizations"), so the reader is able to see concretely the ideas the student is communicating.

Leaving Room for Discussion

This thesis statement is not capable of development or advancement in the paper:

Needs Improvement: There are always alternatives to illegal drug use.

This sample thesis statement makes a claim, but it is not a claim that will sustain extended discussion. This claim is the type of claim that might be appropriate for the conclusion of a paper, but in the beginning of the paper, the student is left with nowhere to go. What further points can be made? If there are "always alternatives" to the problem the student is identifying, then why bother developing a paper around that claim? Ideally, a thesis statement should be complex enough to explore over the length of the entire paper.

Better: The most effective treatment plan for methamphetamine addiction may be a combination of pharmacological and cognitive therapy, as argued by Baker (2008), Smith (2009), and Xavier (2011).

In the revised thesis, you can see the student make a specific, debatable claim that has the potential to generate several pages' worth of discussion. When drafting a thesis statement, think about the questions your thesis statement will generate: What follow-up inquiries might a reader have? In the first example, there are almost no additional questions implied, but the revised example allows for a good deal more exploration.

Thesis Mad Libs

If you are having trouble getting started, try using the models below to generate a rough model of a thesis statement! These models are intended for drafting purposes only and should not appear in your final work.

• In this essay, I argue ____, using ______ to assert _____.
• While scholars have often argued ______, I argue______, because_______.
• Through an analysis of ______, I argue ______, which is important because_______.

Words to Avoid and to Embrace

When drafting your thesis statement, avoid words like explore, investigate, learn, compile, summarize , and explain to describe the main purpose of your paper. These words imply a paper that summarizes or "reports," rather than synthesizing and analyzing.

Instead of the terms above, try words like argue, critique, question , and interrogate . These more analytical words may help you begin strongly, by articulating a specific, critical, scholarly position.

How to proofread your thesis

1. Review your institution's guidelines

2. take a break before you read anything, 3. determine how to proofread your thesis, 4. use online tools, 5. read your thesis in a different order, 6. read your thesis out loud, 7. reach out to your peers, frequently asked questions about proofreading your thesis, related articles.

Now that you've finished your thesis , it's time to proofread it. You'll need to do this several times to ensure that you submit a solid thesis that's free of grammatical mistakes and typos. We've put together a few tips that can help you optimize the proofreading stage of your thesis.

Your institution will likely have specific guidelines for formatting your thesis. Be sure to double-check the guidelines for layout and format issues, including:

• paper size and margins
• running head
• page numbering
• line spacing

Take time to read through the guidelines again and keep them handy as you proofread your thesis.

The proofreading stage is also a good time to check your citations or references . Whether you're using Harvard, APA (American Psychological Association), MLA (Modern Language Association) or some other citation style, make sure that your citations are correct.

Give yourself some time off before you start proofreading your thesis. This allows you to return to your work with fresh eyes. Ideally, you should plan to take a break of several weeks before you begin proofreading; however, even a short break can help you refocus and catch more mistakes.

Some people like to proofread their thesis on screen, while others like to print it out and read it on paper. Whichever method you choose, be aware that you can't read it all at once. Rather, make a plan for how you want to approach proofreading and stick to it. You'll generally want to break up your process by chapter or section.

Consider breaking down your thesis proofreading process in one of these ways:

• by paragraph

Several online tools can help you with proofreading and some of them are even free. Use tools like Grammarly or Proofread Bot for proofreading or Readable.com or Slickwrite to critique your grammar and writing. A quick Google search will show you that there are dozens of tools out there that can help you with your thesis!

Week 1 : Read a chapter a day, watching out for major issues in argumentation, use of evidence, and organization.

Week 2 : Complete substantive revisions and check that all citations are correct. Use a reference manager like Paperpile to create accurate citations and bibliographies.

Week 3 : Re-read each chapter, checking for any additional surface errors. Double-check that your formatting aligns with your department’s thesis requirements.

Try reading your work backwards or in a random order. This approach often works better than reading your work from beginning to end.

By switching up your expectations, you will catch more errors. Plus, starting at the end allows you to keep your conclusions in mind as you read and helps you to verify that you've proven your thesis statement.

The best way to catch grammatical, stylistic, and organizational mistakes is to read your work aloud to yourself. Hearing your own words greatly increases your ability to find typos and errors.

Keep your eye out for the following common errors:

• subject-verb agreement
• faulty predication
• misplaced modifiers
• tense changes
• incorrect citations

If you have friends or peers who are also writing theses, or who have completed them, reach out for advice and help. For instance, blogger Pat Thomson suggests setting up a proofreading deal with a friend.

Also, you might find it useful to join or start a writing group. These groups build accountability and provide writers with support for all stages of the research and writing process.

The length of the proofreading process depends on the length of the thesis. Plus, you should plan to take a couple of weeks off before you start proofreading. It's also a good idea to break up longer projects by chapter or section.

Always double-check your institution's guidelines for the general layout, including:

If you know someone who is willing to proofread your thesis, then definitely ask! Friends and peers who are also working on theses, or who have recently finished, can provide you with useful insights about the grammar, style, and structure of your thesis.

As part of your proofreading plan, you should create a checklist of items that you want to watch out for while proofreading your thesis. Your checklist might include:

• Spelling and typos
• Verb tenses and subject-verb agreement
• Sentence structure
• Layout and formatting
• Citations and/or references
• Consistency of style
• Organization
• Overall flow

You should plan to proofread your thesis as many times as it takes to ensure that you submit a polished and professional work. Typically, however, most thesis writers proofread their work around three to four times.

How to Write a Strong Thesis Statement

A thesis can be found in many places—a debate speech, a lawyer’s closing argument, even an advertisement. But the most common place for a thesis statement (and probably why you’re reading this article) is in an essay.

Whether you’re writing an argumentative paper, an informative essay, or a compare/contrast statement, you need a thesis. Without a thesis, your argument falls flat and your information is unfocused. Since a thesis is so important, it’s probably a good idea to look at some tips on how to put together a strong one.

Guide Overview

What is a “thesis statement” anyway.

• 2 categories of thesis statements: informative and persuasive
• 2 styles of thesis statements
• Formula for a strong argumentative thesis
• The qualities of a solid thesis statement (video)

You may have heard of something called a “thesis.” It’s what seniors commonly refer to as their final paper before graduation. That’s not what we’re talking about here. That type of thesis is a long, well-written paper that takes years to piece together.

Instead, we’re talking about a single sentence that ties together the main idea of any argument . In the context of student essays, it’s a statement that summarizes your topic and declares your position on it. This sentence can tell a reader whether your essay is something they want to read.

2 Categories of Thesis Statements: Informative and Persuasive

Just as there are different types of essays, there are different types of thesis statements. The thesis should match the essay.

For example, with an informative essay, you should compose an informative thesis (rather than argumentative). You want to declare your intentions in this essay and guide the reader to the conclusion that you reach.

To make a peanut butter and jelly sandwich, you must procure the ingredients, find a knife, and spread the condiments.

This thesis showed the reader the topic (a type of sandwich) and the direction the essay will take (describing how the sandwich is made).

Most other types of essays, whether compare/contrast, argumentative, or narrative, have thesis statements that take a position and argue it. In other words, unless your purpose is simply to inform, your thesis is considered persuasive. A persuasive thesis usually contains an opinion and the reason why your opinion is true.

Peanut butter and jelly sandwiches are the best type of sandwich because they are versatile, easy to make, and taste good.

In this persuasive thesis statement, you see that I state my opinion (the best type of sandwich), which means I have chosen a stance. Next, I explain that my opinion is correct with several key reasons. This persuasive type of thesis can be used in any essay that contains the writer’s opinion, including, as I mentioned above, compare/contrast essays, narrative essays, and so on.

2 Styles of Thesis Statements

Just as there are two different types of thesis statements (informative and persuasive), there are two basic styles you can use.

The first style uses a list of two or more points . This style of thesis is perfect for a brief essay that contains only two or three body paragraphs. This basic five-paragraph essay is typical of middle and high school assignments.

C.S. Lewis’s Chronicles of Narnia series is one of the richest works of the 20th century because it offers an escape from reality, teaches readers to have faith even when they don’t understand, and contains a host of vibrant characters.

In the above persuasive thesis, you can see my opinion about Narnia followed by three clear reasons. This thesis is perfect for setting up a tidy five-paragraph essay.

In college, five paragraph essays become few and far between as essay length gets longer. Can you imagine having only five paragraphs in a six-page paper? For a longer essay, you need a thesis statement that is more versatile. Instead of listing two or three distinct points, a thesis can list one overarching point that all body paragraphs tie into.

Good vs. evil is the main theme of Lewis’s Narnia series, as is made clear through the struggles the main characters face in each book.

In this thesis, I have made a claim about the theme in Narnia followed by my reasoning. The broader scope of this thesis allows me to write about each of the series’ seven novels. I am no longer limited in how many body paragraphs I can logically use.

Formula for a Strong Argumentative Thesis

One thing I find that is helpful for students is having a clear template. While students rarely end up with a thesis that follows this exact wording, the following template creates a good starting point:

___________ is true because of ___________, ___________, and ___________.

Conversely, the formula for a thesis with only one point might follow this template:

___________________ is true because of _____________________.

Students usually end up using different terminology than simply “because,” but having a template is always helpful to get the creative juices flowing.

The Qualities of a Solid Thesis Statement

When composing a thesis, you must consider not only the format, but other qualities like length, position in the essay, and how strong the argument is.

Length: A thesis statement can be short or long, depending on how many points it mentions. Typically, however, it is only one concise sentence. It does contain at least two clauses, usually an independent clause (the opinion) and a dependent clause (the reasons). You probably should aim for a single sentence that is at least two lines, or about 30 to 40 words long.

Position: A thesis statement always belongs at the beginning of an essay. This is because it is a sentence that tells the reader what the writer is going to discuss. Teachers will have different preferences for the precise location of the thesis, but a good rule of thumb is in the introduction paragraph, within the last two or three sentences.

Strength: Finally, for a persuasive thesis to be strong, it needs to be arguable. This means that the statement is not obvious, and it is not something that everyone agrees is true.

Example of weak thesis:

Peanut butter and jelly sandwiches are easy to make because it just takes three ingredients.

Most people would agree that PB&J is one of the easiest sandwiches in the American lunch repertoire.

Example of a stronger thesis:

Peanut butter and jelly sandwiches are fun to eat because they always slide around.

This is more arguable because there are plenty of folks who might think a PB&J is messy or slimy rather than fun.

Composing a thesis statement does take a bit more thought than many other parts of an essay. However, because a thesis statement can contain an entire argument in just a few words, it is worth taking the extra time to compose this sentence. It can direct your research and your argument so that your essay is tight, focused, and makes readers think.

How to Proofread a Thesis: A Guide

Anyone who has written one knows that a thesis is a monumental task. Months or even years of research, writing, and revision go into creating a thesis. The moment you type the last word, you may feel an incredible sense of relief. But you aren’t done yet! Now it’s time to begin the second most challenging part of writing a thesis: editing and proofreading. Your thesis will no doubt go through various rounds of editing as you reread and rewrite different sections, and your advisor provides their input. But even after all that, there is one critical step left, which is thesis proofreading. Is thesis proofreading that important? How can you go about thesis proofreading anyway?

What is Thesis Proofreading? Proofreading is a separate step where you carefully review a text to ensure its technical accuracy. Thesis proofreading should be conducted after all of your major content editing has been finished. This is to save both time and effort. After all, why bother reviewing a section that will be deleted later? If you proofread before you are done editing, you may have to go back and proofread new sections that are added or changed during the editing process. Thesis proofreading should only take place once you are really, for real, finally done with editing.

In addition to technical accuracy, such as spelling, grammar, punctuation, and formatting, thesis proofreading should double-check that your word choice is correct. Proofreading your thesis will also give you the chance to check one more time for clarity and typographical errors. Finally, thesis proofreading will let you make sure that your word choices, use of abbreviations, and use of capitalization are consistent throughout your text. Thesis proofreading is a critical step because any errors in a written document make the document seem less professional and trustworthy. This is doubly true when it comes to academic circles. In this article, we talk specifically about English proofreading, but keep in mind that thesis proofreading is a critical step no matter what language you wrote your masterpiece in.

How Do You Proofread a Thesis? When it comes to performing the English proofreading of your thesis, you have a couple of options. The first option is to proofread your own thesis. This can save you some money, but it can also involve a lot of time and difficulty. Proofreading your own work is always a challenge, thesis or otherwise, because you will bring your own bias as the writer to the table. You wrote it, and you know what you wanted to say. For that reason, it can be very easy to miss your own errors. This is why many thesis writers choose to hire thesis proofreading services. If you are a non-native English speaker, hiring thesis proofreading services to perform English proofreading is often your best option. English proofreading is difficult for native speakers too, and experienced dissertation editors employed by thesis proofreading services can often provide you with a very high quality of service.

Your thesis is probably long, and so it can help to do your thesis proofreading in sections rather than all at once. More importantly, do not attempt to proofread your thesis immediately upon finishing your final draft. You need as much time and space between you and your thesis as possible before you begin the proofreading process. If you aren’t engaging the help of thesis proofreading services, put your thesis on the shelf for at least 72 hours, preferably a week, before you begin the thesis proofreading process. That way, you can look at it with fresh eyes, and you’ll be more likely to catch the errors you have made.

What Should I Look For When Proofreading? Anyone doing their own thesis proofreading should begin with a checklist of items to review. Common errors that should be looked for include:

• Inconsistent use of UK and US English (especially common among non-native speakers)
• Spelling errors (spell check is useful but will not catch everything)
• Typographical errors (abort instead of about is a nasty error but will be missed by spell check!)
• Inconsistent abbreviations (U.S. vs. US)
• Punctuation errors (improper use of apostrophes, inconsistent use of the Oxford comma, en dashes instead of em dashes)
• Grammatical errors (incorrect use of a/an/the, pluralization, etc.)

The easiest way to eliminate inconsistent use of UK vs. US English is to make sure the language of your document is set for your preferred version of English and then perform a quick spell check using the spell-check tool. This should take care of most spelling issues, but also keep a careful eye out as you read through your paper for any inconsistencies you may have missed.

One additional item you’ll want to take special care with is use of contractions (don’t vs. do not) and apostrophes. In general, academic writing is formal and use of contractions is discouraged. Some style guides (APA, for example) specifically discourage the use of contractions. Similarly, non-native speakers often have a tendency to overuse apostrophes with plural possessives. English proofreading and writing strongly advise against this, as native speakers are taught not to write this way. For example, “the dogs’ group” should be “the group of dogs” and “the publics’ opinion” should be “public opinion” or “the opinion of the public.” In addition, you should make sure that your formatting is consistent. Are headlines aligned the same way? Did you use bold for one section and italics for another? Are the margins correct? Always refer to the guide provided by your university to ensure you have properly formatted your thesis before submission.

Where Can I Find Help with Thesis Proofreading? There are a number of helpful guides and tools out there to assist you in thesis proofreading. Google Scholar can help you double-check your citations, as can citation generators. OWL Purdue online also has many helpful writing tips. Thesis proofreading services, as mentioned above, are also a great resource. In addition to thesis proofreading services, academic proofreading services are also available. What is academic proofreading? Simply put, academic proofreading is specifically targeted to academics. Academic and thesis proofreading services employ experienced dissertation editors who are familiar with specific academic disciplines to review academic articles and thesis manuscripts. Because of their familiarity with the subject matter, they are fast and thorough.

Proving the Thesis/Critical Thinking

Good writing is not just about presenting information in an organized way such as an essay or research paper with an introduction, body paragraphs, and a concluding paragraph.  It is about persuading your reader that you are right.  In the case of an academic paper, the body paragraphs each must have a proof point (a topic sentence), and the content of each of the body paragraphs must include information that shows that the proof point is accurate.  There are a number of ways to achieve this goal.

This section covers how to critically evaluate your writing with some general information in Proving the Thesis - General Principles and then goes on to explain logical thinking in Proving the Thesis - Logic and problems with logic in Proving the Thesis - Logical Fallacies and Appeals.  Rhetorical modes such as description, definition, cause and/or effect, and compare/contract can be used to help prove the thesis.

The same principles are applied when you are evaluating someone else's presentation whether it is a potential source for a paper or simply reading a news article.  Even what is called a documentary - which presumably is the truth - should be critically evaluated.

Proving the Thesis - General Principles

Stay focused on purpose.

It is critical to keep focused on the purpose of your writing: to prove the thesis.  If you are planning an essay, start with at least a scratch outline and a working thesis – a starting thesis that you know you might change as you draft your paper.  If you are writing an essay exam or paper, be sure to identify the key terms in the instructions such as the following and don’t stray from the topic and/or question or what the instructions say to do: analyze, clarify, classify, compare, contrast, define, describe, discuss, evaluate, explain, identify, illustrate, interpret, justify, relate, summarize, support, or trace.  Remember to review and revise. See Writiing Process and Outlining in Related Pages on the right sidebar.

Relevance, Reliability, Accuracy, and Sufficiency

The information presented to prove the thesis should be relevant, reliable, credible, and sufficient.

• relevant evidence  – evidence must be directly and clearly related to proving the thesis
• reliable evidence  – evidence must be consistent and accurate; the same circumstances must have the same result
• reliable narrator  –  there is general presumption in sources that are purportedly factual is that the writer is reliable; however, that it is not necessarily accurate that the writer is presenting consistent or even accurate information even when that writer thinks he or she is.  The term  reliable narrator  is used more frequently in literary analysis to describe that the person telling the story can be trusted to be giving reliable information.
• unreliable narrator  – an unreliable narrator is where when the person writing the source is not consistent or accurate. The term  reliable narrator  is used more frequently in literary analysis to describe that the person telling the story cannot be trusted to be giving reliable information.
• accurate evidence  –  for evidence to be credible, it must be factual.  Even one inaccurate piece of information will cause the reader to doubt an author’s credibility.
• sufficient evidence  – evidence must be sufficient.  Sufficiency is a question of whether even though the evidence used to prove the thesis may be reliable and accurate, it may not be enough to prove the thesis
• representative evidence  – a consideration related to relevance, reliability, credibility, and sufficiency is whether the evidence represents the entire group involved in the analysis.  For example, evidence which is relevant, reliable, accurate, and sufficient that shows a high correlation of pesticide content in certain foods may not have been drawn from samples from all over the country, so the incidence may be limited only to the area from which the sample was drawn

Transitional Devices

A good paper must have  coherence . This means that all the ideas should be in a logical order and fit together like links in a chain.  One way to do this is to have an overall plan for how the paper will develop, such as in an outline. Another is to use transitional devices.

Transitional devices are a word or words that help one sentence or paragraph flow into the next. Here is an example of two sentences which do not have any transitional information to connect them:

The weather looked threatening. They went on their picnic.

In the above example, we are unsure how these two ideas relate to each other.  See how one word connects the two thoughts in the following example:

The weather looked threatening. Nevertheless, they went on their picnic.

Now we understand the relationship between the ideas. The word  Nevertheless  serves as a transitional device from one sentence to the next.

Transitional devices can be more than just a word. They can also be entire phrases. Here is an example of a sentence with a phrase that serves as a transitional device.

In spite of the cloudy sky, they went on their picnic.

The words  In spite of the cloudy sky  are a transitional device.

Just as there should be transitions between sentences, paragraphs should also link together. There are a few ways to do this.

• Refer to key words or thoughts from the thesis.
• Refer to key words or ideas from the preceding paragraph.
• Use transitional expressions.
• Use transitional sentences.

Using transitions in your paper is like using signals when you drive. Imagine following someone in a car who is leading you to a place you’ve never been before. Think about how difficult it would be to follow him to the correct destination if he didn’t signal! Just as in driving, you don’t want to take a turn in your paper and risk leaving your readers behind.

Facts and Statistics

Facts and statistics can be very persuasive.  In fact, a critical reader will challenge the accuracy or the legitimacy of the sources for purported facts and statistics.

It is important to investigate those ourselves before we use information that is supposed to be factual.  We should know exactly where the information comes from and evaluate whether the source is credible.  It is not a good idea to present information as though it is a fact unless you know it is a fact.

Statistics can be manipulated.  An educated audience will pick that up and you’ll lose credibility if they sense that the presentation of statistics is not honest.

Here’s an example:

A board president claimed that ninety percent of the people who responded to a survey wanted a certain action taken.  When asked how many responded to the survey, he answered that ten people had responded.

Primary and Secondary Sources

A  primary source  is a source written by the person providing the information.  If you get information from your friend, the friend is the primary source.

In research, it is preferable to get information directly from the source when it is available.

Secondary sources  are not directly from the provider of the information.  It is like getting information about what Joan said from John.  This information is not as reliable as primary sources.  However, it is common practice for authors to include what others have said in their articles and analyze what was said.

Pictures, charts, graphs, drawings, and diagrams; not appropriate in writing for all courses – check with instructor if not indicated on assignment

Rhetorical Modes as Types of Proof

Narration is the use of language to tell a story. It is the telling of a sequence of events or occurrences.  As a method of helping to prove a thesis, narration might be used tell the experience of the author or of someone else.  For example, in a paper discussing allergies, a writer might narrate his or her experiences with allergies and what was done to control exposure to the allergens or treat the symptoms.

It is important, especially when dealing with a complex topic, that you define all the key terms in your argument. This is important because not all definitions are universally agreed upon. Take the idea of immigration reform. For some this could mean providing a path to citizenship for illegal immigrants; for others, it could mean tighter border security.

How you define something influences how you and your audience see a particular issue.  Even the terms used to describe an issue can influence the reader. Take for example the difference in calling someone an “illegal immigrant” versus an “undocumented worker.”

Using the first entry in a standard dictionary is not usually sufficient, especially when writing about something very technical. Some areas have specialized dictionaries to define specific terms. The word  gross is  used very differently if used in everyday language or by a medical clinician.  In everyday language, the word  gross  means awful or disgusting.  However, in medical language the word gross means large.

Be careful not to use vague or judgmental words in your definition as it can seem to your readers that you are biased or imprecise.

Division and Classification

With complicated topics, it might helpful to separate the bigger topic or subject area into smaller parts and classify the information according to separate criteria.  For example, in discussing plants, it could help to discuss by categories of plants.

Description

Description is to help bring the reader into the writing.  Specific descriptions of sensations including sights, sounds, smell, touch, and taste can make the reader feel as though he or she is part of the experience which can be a useful strategy in proving a thesis.

Process Analysis

Using examples and facts can support your paper, but simply using these is not enough; you must also think critically about what you have read and react to it. Analysis means to go beyond the obvious and beyond what is literally in the text.

It is very tempting when writing a paper to simply paraphrase or summarize a source than it is to think critically about what was written. Often, when the source is difficult to understand, just repeating his or her words may seem simpler.

Analysis, however, requires a complete understanding of the point the author is making because you must take a complex idea, break it down in to smaller, simpler parts, and then figure out how they fit together.

Examples and Illustrations

Using examples is a way to explain or to prove that our position is accurate.  Examples can be true or actual situations or they can be hypothetical.

Using examples are more effective if they are close to or exactly the same circumstances as in the case you are trying to prove.  If a person can think to themselves that there is a significant difference, the example will not be effective.

If you are using an actual event, you should be careful to be sure you are familiar with the details.  If not, using the example can backfire and convince the person of the opposite.

If you use a hypothetical situation as an example, you should think it through completely first.  Again, if it is not a good example, it would weaken your position.

Attorneys use example to argue cases.  In fact, if they can present a previously decided case in the same jurisdiction that matches up with the existing decision, the judge must decide in their favor.  The supportive case has to be “on all fours,” that is, match up on all the essential points.

Compare/Contrast

We compare and contrast things all the time in life to make decisions from where we buy our groceries to what car to buy. Just as in life, college papers also often require comparing and contrasting. You might have to compare two historic events, world leaders, or poems. Often, even if it is not required, ideas become clearer when you evaluate them in relation to one another.

It is important to remember to be fair when contrasting ideas to show that one is superior.  If you note only the strengths of one and only the faults of the other, your readers may determine that your argument is weak or not credible.

One way to do this is to think about how they are similar in addition to how they differ.  Take the words  liberal  and  conservative  for example. Usually these are seen as very different things, but they do have similarities. They both are political philosophies, they both have a moral underpinning, and they both have people who passionately support their ideals.

Cause/Effect

Another way of proving a thesis is to show the causes and/or effects.  For example, if your thesis is that the use of wind power is the best way of producing electricity, showing the effects of how much electricity can be produced is good proof.  You could also include the bad effects of some other means of producing electricity.

Persuasion/Argumentation

In a way, all communication has a purpose: to persuade or argue for the validity of what is being said.  Even when a person is expressing an emotion, effective communication involves convincing the audience that those feelings are legitimate.

The same strategies used to develop a good writing are used when the purpose is specifically to persuade.  Transitional devices, use of examples, facts and statistics, primary and secondary sources, and rhetorical modes including analysis, definition, comparison/contrast, and cause and/or Effect are ways to prove your point.

See the difference in how these strategies can be used for persuasion.

A simple sentence:  It was a cold day.

Transitional device:  In addition to being dark and cloudy, it was a cold day.

Example:  It was so cold that the chill of the air was felt right through layers of clothing.

Facts/Statistics:  It was a record-breaking cold with temperatures plummeting below 15o F.

Primary Source:  According to Jones, “Temperatures fell as though we were entering another Ice Age.”

Secondary Source:  Goldstein agreed: “This cold wave surpasses any recorded to date” (qtd. in Jones).

Rhetorical Modes

Narration:  While I was walking in the park, I noticed that it was a cold day.

Definition:  The temperature at which water freezes is 32o F.  This is typically the temperature used to describe weather conditions as  freezing.

Description:  It was so cold that frost was forming on the windows and the leaves on the plants were curling.

Process Analysis:  The measurement of what is considered  a cold day  includes the temperature and humidity reading along with any wind-chill factor.

Comparison/Contrast:  It was so cold this year that the strawberries froze and fell to the ground whereas last year’s crop survived the freeze.

Cause/Effect:  Because it was so cold, the strawberries froze and fell to the ground.

Persuasion/Argumentation:  The reading on the thermometer of 32o F, the frost or the windows, and the curling leaves of the plants show it was a cold day.

Proving the Thesis - Logic

Learning about logical thinking helps us in two ways:  we learn to evaluate and use information better and we learn how to better present information to others to prove our point.  In other words, we learn to critical think about information we hear or see, and we learn to think better ourselves.

Inductive Reasoning

There are different kinds of reasoning.  Inductive reasoning  is  logic that draws a generalization from a particular piece of information.  For example, a person who has only seen red colored roses might (erroneously) infer that all roses are red. Inductive reasoning is subject to error since the particular observation is not necessarily representative of a larger group.  Sometimes, this type of thinking causes people to infer that some bad attribute of one in a group exists among all in that group such as seeing one rotting apple in the bag, makes an inductive leap that all the apples must be rotting.  Of course, this doesn't really make sense, but people make these kinds of hasty generalizations all the time which is an error in logic.

Deductive Reasoning 

Deductive reasoning is logic that draws a conclusion about a particular situation from a general rule.  This is more likely to result in an accurate conclusion since a general rule usually applies to all situations within its category: All flowers need water; therefore, petunias need water. 

A syllogism is a three-part sequence of reasoned thoughts to draw a logical conclusion: All flowers need water. Petunias are flowers. Petunias need water.

The syllogism consists of a major premise, a minor premise, and a conclusion.  The major premise is the general or universal assumption used to make a logical analysis: All flowers need water.  Note that if a major premise is not accurate, the resulting conclusion will not be accurate although it may be logical.

The minor premise is the assumption pertaining to an example in the major premise: Petunias are flowers.  Note that if a minor premise is not accurate, the resulting conclusion will not be accurate although it may be logical.  The conclusion (logical conclusion) is the resulting logical thought of analyzing the major and minor premise.  Logical conclusions are not necessarily true or accurate since the major premise or minor premise may not be accurate.

Other Terms Related to Logic

self-evident  – evidence that is apparent by observation or reasoning

valid argument  – an argument which is based on logical analysis of information; not necessarily true

sound argument  – an argument based on a syllogism that has accurate major and minor premises

Toulmin Logic

Toulmin Logic a form of logic that uses claim, grounds, and warrant for analyzing the logic of an argument

claim  – the thesis; the point that is to be proved in Toulmin Logic

grounds  – the evidence (proof, support) for the claim in Toulmin Logic

warrant  – the result assumption of an analysis of claim and grounds in Toulmin Logic.

Proving the Thesis - Logical Fallacies and Appeals

Logical fallacies (flawed logic) .

A logical fallacy is a fallacy in logic.  It is flawed logic.  In order to be convincing, using logic is important. Also, identifying the flaws in what someone is saying or writing is necessary for a critical analysis.

There are several logical fallacies:

• sweeping generalization  – hasty generalization resulting in conclusion that is not necessarily accurate;  inductive reasoning (going from a particular point to a universal rule) which is not thought through carefully.  There is one rotting apple in the bag; therefore, all the apples in the bag are rotting.
• argument to the person (ad hominem)  – a statement raising questions about a person’s honesty or integrity who is taking a stand on an issue instead of making an argument on the issue itself.  The candidate opposing the widening of the road is being investigated for tax evasion instead of arguing that the widening of the road is needed to alleviate traffic on another road.
• non sequitur  – an line of argument that really does follow logically.  The road should not be widened because the city park is nearby.  What does the park have to do with widening of the road? This often happens when the argument is just not clearly expressed.  The road should not be widened because it will increase traffic on a street that many children cross to go to the city park.
• either/or fallacy  – where only two choices are presented instead of giving all the options.  The county commissioners asked residents if they preferred a slight increase in taxes or charging a parking fee for on all county parks.
• begging the question  – using the argument that something is true or accurate because it is true or accurate.
• bandwagon argument  – Everyone else is doing it; therefore, you should
• appeals  – use of language to sway the reader by appealing to emotions, logic, or ethics.
• strawman fallacy  – where the opponent’s position is unfairly shown to be extreme or illogical in order to minimize its strength.
• false comparison fallacy  – where a position is compared to something which has some similarities but which is not comparable in a significant way resulting in a false negative comparison
• faulty causality fallacy  – where an occurrence or event is represented to cause another occurrence or event because they happen at the same time or close in time
• slippery slope fallacy  – where an action is represented to result in an adverse consequence even though that consequence is very remote.
• red herring fallacy  – where an irrelevant issue or situation is raised to distract the argument from the point; changing the subject

Appeals are the use of language designed to create a particular type of response in the audience.  There are three types of appeals.

• emotional appeals  – presenting information designed to result in emotion.  Commercials typically have emotional appeals to make the audience feel in a certain way.  Perfume commercials showing couples; diaper commercials showing happy babies.  There are many speeches that used emotional appeals to show the audience the validity of the point being made.
• logical appeals  – presenting information designed to result in the audience thinking that what is being promoted is logical.  Examples include a commercial to refinance focuses on how money can be saved or an evaluation as to the beneficial effects of a specific course of action such as more community participation or a source of revenue for a business.
• ethical appeals  – presenting information designed to result in the audience thinking that what is being promoted is the right thing such as contributing to organizations that help victims of natural disasters.

Some use of appeals are thought to be unfair such as images of abused pets or hungry children.  People tend to react emotionally instead of evaluating whether the particular organization will make good use of donations.

Proving the Thesis - Rhetorical Mode

Rhetoric is the art of persuasion.  In addition to using techniques such as unity and coherence and logic, the modes of rhetoric are used.  Rhetorical modes are ways to use language for persuasion. In addition to using a sentence variety, unity and coherence, and logic, modes such as narration, comparing and contrasting, and cause and/or effect to prove a point.  These can be used within a paragraph as well as the approach for an entire essay.

Types of Rhetorical Modes

Narration is when an author writes as though telling a story.  This mode is used more often in fiction, but it can be used in academic essay writing when the best way to help prove the thesis is by relating a sequence of events.

Description/Definition/Exemplification, and Classification

These closely related modes use specific information about certain aspects of a thing, event, or situation. The terms speak for themselves.  Description uses details describing the thing, event, or situation. Definition defines it. Exemplification uses examples, and classification uses categories.

The rose was red. (description)

A rose is a flower with soft petals and a beautiful, brief bloom. (definition)

Roses comes in a variety of colors such as red, yellow, and white. (example)

Roses come in a variety of types including miniature, climbing, hybrid tea, and floribunda. (classification)

Comparing and/or contrasting one thing, event, or situation is a helpful way to show what it is and isn't.  If someone were arguing that a particular type of sneaker was the best, it would be useful to compare to others for support, durability, and price.

Cause and/or Effect

This mode is useful in arguing for or again an action.  Showing the cause and/or effect of an action can be persuasive.  For example, if someone were arguing for an increase in the speed limit, statistics showing an increase in fatalities where limits are higher would be a persuasive argument.

In a sense, the ultimate intent of all communication is persuasion.  Argumentation is one way of talking about debate.  We think of arguing as what we do among friends or family members - and it is - but there is a formal way to argue to prove our point.  Actually, we can learn how to better have civil arguments which will be constructive.  In thinking about persuasion/argumentation as a rhetorical mode, it refers to a type of writing that is clearly arguing in support of a specific point.

Published on 15 September 2022 by Tegan George . Revised on 5 December 2023.

A thesis is a type of research paper based on your original research. It is usually submitted as the final step of a PhD program in the UK.

Writing a thesis can be a daunting experience. Indeed, alongside a dissertation , it is the longest piece of writing students typically complete. It relies on your ability to conduct research from start to finish: designing your research , collecting data , developing a robust analysis, drawing strong conclusions , and writing concisely .

You may have heard the word thesis as a standalone term or as a component of academic writing called a thesis statement . Keep in mind that these are two very different things.

• A thesis statement is a very common component of an essay, particularly in the humanities. It usually comprises 1 or 2 sentences in the introduction of your essay , and should clearly and concisely summarise the central points of your academic essay .
• A thesis is a long-form piece of academic writing, often taking more than a full semester to complete. It is generally a degree requirement to complete a PhD program.
• In many countries, particularly the UK, a dissertation is generally written at the bachelor’s or master’s level.
• In the US, a dissertation is generally written as a final step toward obtaining a PhD.

Prevent plagiarism, run a free check.

The final structure of your thesis depends on a variety of components, such as:

• Your discipline
• Your theoretical approach

Humanities theses are often structured more like a longer-form essay . Just like in an essay, you build an argument to support a central thesis.

In both hard and social sciences, theses typically include an introduction , literature review , methodology section ,  results section , discussion section , and conclusion section . These are each presented in their own dedicated section or chapter. In some cases, you might want to add an appendix .

Thesis examples

We’ve compiled a short list of thesis examples to help you get started.

• Example thesis #1:   ‘Abolition, Africans, and Abstraction: the Influence of the “Noble Savage” on British and French Antislavery Thought, 1787-1807’ by Suchait Kahlon.
• Example thesis #2: ‘”A Starving Man Helping Another Starving Man”: UNRRA, India, and the Genesis of Global Relief, 1943-1947’ by Julian Saint Reiman.

The very first page of your thesis contains all necessary identifying information, including:

• Your full title
• Your full name
• Your department
• Your institution and degree program
• Your submission date.

Sometimes the title page also includes your student ID, the name of your supervisor, or the university’s logo. Check out your university’s guidelines if you’re not sure.

Read more about title pages

The acknowledgements section is usually optional. Its main point is to allow you to thank everyone who helped you in your thesis journey, such as supervisors, friends, or family. You can also choose to write a preface , but it’s typically one or the other, not both.

Read more about acknowledgements Read more about prefaces

An abstract is a short summary of your thesis. Usually a maximum of 300 words long, it’s should include brief descriptions of your research objectives , methods, results, and conclusions. Though it may seem short, it introduces your work to your audience, serving as a first impression of your thesis.

Read more about abstracts

A table of contents lists all of your sections, plus their corresponding page numbers and subheadings if you have them. This helps your reader seamlessly navigate your document.

Your table of contents should include all the major parts of your thesis. In particular, don’t forget the the appendices. If you used heading styles, it’s easy to generate an automatic table Microsoft Word.

Read more about tables of contents

While not mandatory, if you used a lot of tables and/or figures, it’s nice to include a list of them to help guide your reader. It’s also easy to generate one of these in Word: just use the ‘Insert Caption’ feature.

Read more about lists of figures and tables

If you have used a lot of industry- or field-specific abbreviations in your thesis, you should include them in an alphabetised list of abbreviations . This way, your readers can easily look up any meanings they aren’t familiar with.

Read more about lists of abbreviations

Relatedly, if you find yourself using a lot of very specialised or field-specific terms that may not be familiar to your reader, consider including a glossary . Alphabetise the terms you want to include with a brief definition.

Read more about glossaries

An introduction sets up the topic, purpose, and relevance of your thesis, as well as expectations for your reader. This should:

• Ground your research topic , sharing any background information your reader may need
• Define the scope of your work
• Introduce any existing research on your topic, situating your work within a broader problem or debate
• State your research question(s)
• Outline (briefly) how the remainder of your work will proceed

In other words, your introduction should clearly and concisely show your reader the “what, why, and how” of your research.

Read more about introductions

A literature review helps you gain a robust understanding of any extant academic work on your topic, encompassing:

• Selecting relevant sources
• Determining the credibility of your sources
• Critically evaluating each of your sources
• Drawing connections between sources, including any themes, patterns, conflicts, or gaps

A literature review is not merely a summary of existing work. Rather, your literature review should ultimately lead to a clear justification for your own research, perhaps via:

• Addressing a gap in the literature
• Building on existing knowledge to draw new conclusions
• Exploring a new theoretical or methodological approach
• Introducing a new solution to an unresolved problem
• Definitively advocating for one side of a theoretical debate

Read more about literature reviews

Theoretical framework

Your literature review can often form the basis for your theoretical framework, but these are not the same thing. A theoretical framework defines and analyses the concepts and theories that your research hinges on.

Read more about theoretical frameworks

Your methodology chapter shows your reader how you conducted your research. It should be written clearly and methodically, easily allowing your reader to critically assess the credibility of your argument. Furthermore, your methods section should convince your reader that your method was the best way to answer your research question.

A methodology section should generally include:

• Your overall approach ( quantitative vs. qualitative )
• Your research methods (e.g., a longitudinal study )
• Your data collection methods (e.g., interviews or a controlled experiment
• Any tools or materials you used (e.g., computer software)
• The data analysis methods you chose (e.g., statistical analysis , discourse analysis )
• A strong, but not defensive justification of your methods

Read more about methodology sections

Your results section should highlight what your methodology discovered. These two sections work in tandem, but shouldn’t repeat each other. While your results section can include hypotheses or themes, don’t include any speculation or new arguments here.

Your results section should:

• State each (relevant) result with any (relevant) descriptive statistics (e.g., mean , standard deviation ) and inferential statistics (e.g., test statistics , p values )
• Explain how each result relates to the research question
• Determine whether the hypothesis was supported

Additional data (like raw numbers or interview transcripts ) can be included as an appendix . You can include tables and figures, but only if they help the reader better understand your results.

Read more about results sections

Your discussion section is where you can interpret your results in detail. Did they meet your expectations? How well do they fit within the framework that you built? You can refer back to any relevant source material to situate your results within your field, but leave most of that analysis in your literature review.

For any unexpected results, offer explanations or alternative interpretations of your data.

Read more about discussion sections

Your thesis conclusion should concisely answer your main research question. It should leave your reader with an ultra-clear understanding of your central argument, and emphasise what your research specifically has contributed to your field.

Why does your research matter? What recommendations for future research do you have? Lastly, wrap up your work with any concluding remarks.

Read more about conclusions

In order to avoid plagiarism , don’t forget to include a full reference list at the end of your thesis, citing the sources that you used. Choose one citation style and follow it consistently throughout your thesis, taking note of the formatting requirements of each style.

Which style you choose is often set by your department or your field, but common styles include MLA , Chicago , and APA.

Create APA citations Create MLA citations

In order to stay clear and concise, your thesis should include the most essential information needed to answer your research question. However, chances are you have many contributing documents, like interview transcripts or survey questions . These can be added as appendices , to save space in the main body.

Read more about appendices

Once you’re done writing, the next part of your editing process begins. Leave plenty of time for proofreading and editing prior to submission. Nothing looks worse than grammar mistakes or sloppy spelling errors!

Consider using a professional thesis editing service to make sure your final project is perfect.

Once you’ve submitted your final product, it’s common practice to have a thesis defense, an oral component of your finished work. This is scheduled by your advisor or committee, and usually entails a presentation and Q&A session.

After your defense, your committee will meet to determine if you deserve any departmental honors or accolades. However, keep in mind that defenses are usually just a formality. If there are any serious issues with your work, these should be resolved with your advisor way before a defense.

The conclusion of your thesis or dissertation shouldn’t take up more than 5-7% of your overall word count.

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

If you only used a few abbreviations in your thesis or dissertation, you don’t necessarily need to include a list of abbreviations .

If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimising confusion about abbreviations unfamiliar to your reader.

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organise your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation, such as:

• Your anticipated title
• Your abstract
• Your chapters (sometimes subdivided into further topics like literature review, research methods, avenues for future research, etc.)

Teens come up with trigonometry proof for Pythagorean Theorem, a problem that stumped math world for centuries

By Bill Whitaker

May 5, 2024 / 7:00 PM EDT / CBS News

As the school year ends, many students will be only too happy to see math classes in their rearview mirrors. It may seem to some of us non-mathematicians that geometry and trigonometry were created by the Greeks as a form of torture, so imagine our amazement when we heard two high school seniors had proved a mathematical puzzle that was thought to be impossible for 2,000 years. 

We met Calcea Johnson and Ne'Kiya Jackson at their all-girls Catholic high school in New Orleans. We expected to find two mathematical prodigies.

Instead, we found at St. Mary's Academy , all students are told their possibilities are boundless.

Come Mardi Gras season, New Orleans is alive with colorful parades, replete with floats, and beads, and high school marching bands.

In a city where uniqueness is celebrated, St. Mary's stands out – with young African American women playing trombones and tubas, twirling batons and dancing - doing it all, which defines St. Mary's, students told us.

Junior Christina Blazio says the school instills in them they have the ability to accomplish anything. 

Christina Blazio: That is kinda a standard here. So we aim very high - like, our aim is excellence for all students. 

The private Catholic elementary and high school sits behind the Sisters of the Holy Family Convent in New Orleans East. The academy was started by an African American nun for young Black women just after the Civil War. The church still supports the school with the help of alumni.

In December 2022, seniors Ne'Kiya Jackson and Calcea Johnson were working on a school-wide math contest that came with a cash prize.

Ne'Kiya Jackson: I was motivated because there was a monetary incentive.

Calcea Johnson: 'Cause I was like, "$500 is a lot of money. So I-- I would like to at least try."

Both were staring down the thorny bonus question.

Bill Whitaker: So tell me, what was this bonus question?

Calcea Johnson: It was to create a new proof of the Pythagorean Theorem. And it kind of gave you a few guidelines on how would you start a proof.

The seniors were familiar with the Pythagorean Theorem, a fundamental principle of geometry. You may remember it from high school: a² + b² = c². In plain English, when you know the length of two sides of a right triangle, you can figure out the length of the third.

Both had studied geometry and some trigonometry, and both told us math was not easy. What no one told  them  was there had been more than 300 documented proofs of the Pythagorean Theorem using algebra and geometry, but for 2,000 years a proof using trigonometry was thought to be impossible, … and that was the bonus question facing them.

Bill Whitaker: When you looked at the question did you think, "Boy, this is hard"?

Ne'Kiya Jackson: Yeah. 

Bill Whitaker: What motivated you to say, "Well, I'm going to try this"?

Calcea Johnson: I think I was like, "I started something. I need to finish it." 

Bill Whitaker: So you just kept on going.

Calcea Johnson: Yeah.

For two months that winter, they spent almost all their free time working on the proof.

CeCe Johnson: She was like, "Mom, this is a little bit too much."

CeCe and Cal Johnson are Calcea's parents.

CeCe Johnson:   So then I started looking at what she really was doing. And it was pages and pages and pages of, like, over 20 or 30 pages for this one problem.

Cal Johnson: Yeah, the garbage can was full of papers, which she would, you know, work out the problems and-- if that didn't work she would ball it up, throw it in the trash. 

Bill Whitaker: Did you look at the problem? 

Neliska Jackson is Ne'Kiya's mother.

Neliska Jackson: Personally I did not. 'Cause most of the time I don't understand what she's doing (laughter).

Michelle Blouin Williams: What if we did this, what if I write this? Does this help? ax² plus ….

Their math teacher, Michelle Blouin Williams, initiated the math contest.

Bill Whitaker: And did you think anyone would solve it?

Michelle Blouin Williams: Well, I wasn't necessarily looking for a solve. So, no, I didn't—

Bill Whitaker: What were you looking for?

Michelle Blouin Williams: I was just looking for some ingenuity, you know—

Calcea and Ne'Kiya delivered on that! They tried to explain their groundbreaking work to 60 Minutes. Calcea's proof is appropriately titled the Waffle Cone.

Calcea Johnson: So to start the proof, we start with just a regular right triangle where the angle in the corner is 90°. And the two angles are alpha and beta.

Bill Whitaker: Uh-huh

Calcea Johnson: So then what we do next is we draw a second congruent, which means they're equal in size. But then we start creating similar but smaller right triangles going in a pattern like this. And then it continues for infinity. And eventually it creates this larger waffle cone shape.

Calcea Johnson: Am I going a little too—

Bill Whitaker: You've been beyond me since the beginning. (laughter) 

Bill Whitaker: So how did you figure out the proof?

Ne'Kiya Jackson: Okay. So you have a right triangle, 90° angle, alpha and beta.

Bill Whitaker: Then what did you do?

Ne'Kiya Jackson: Okay, I have a right triangle inside of the circle. And I have a perpendicular bisector at OP to divide the triangle to make that small right triangle. And that's basically what I used for the proof. That's the proof.

Bill Whitaker: That's what I call amazing.

Ne'Kiya Jackson: Well, thank you.

There had been one other documented proof of the theorem using trigonometry by mathematician Jason Zimba in 2009 – one in 2,000 years. Now it seems Ne'Kiya and Calcea have joined perhaps the most exclusive club in mathematics. 

Bill Whitaker: So you both independently came up with proof that only used trigonometry.

Ne'Kiya Jackson: Yes.

Bill Whitaker: So are you math geniuses?

Calcea Johnson: I think that's a stretch. 

Bill Whitaker: If not genius, you're really smart at math.

Ne'Kiya Jackson: Not at all. (laugh) 

To document Calcea and Ne'Kiya's work, math teachers at St. Mary's submitted their proofs to an American Mathematical Society conference in Atlanta in March 2023.

Ne'Kiya Jackson: Well, our teacher approached us and was like, "Hey, you might be able to actually present this," I was like, "Are you joking?" But she wasn't. So we went. I got up there. We presented and it went well, and it blew up.

Bill Whitaker: It blew up.

Calcea Johnson: Yeah. 

Ne'Kiya Jackson: It blew up.

Bill Whitaker: Yeah. What was the blowup like?

Calcea Johnson: Insane, unexpected, crazy, honestly.

It took millenia to prove, but just a minute for word of their accomplishment to go around the world. They got a write-up in South Korea and a shout-out from former first lady Michelle Obama, a commendation from the governor and keys to the city of New Orleans. 

Bill Whitaker: Why do you think so many people found what you did to be so impressive?

Ne'Kiya Jackson: Probably because we're African American, one. And we're also women. So I think-- oh, and our age. Of course our ages probably played a big part.

Bill Whitaker: So you think people were surprised that young African American women, could do such a thing?

Calcea Johnson: Yeah, definitely.

Ne'Kiya Jackson: I'd like to actually be celebrated for what it is. Like, it's a great mathematical achievement.

Achievement, that's a word you hear often around St. Mary's academy. Calcea and Ne'Kiya follow a long line of barrier-breaking graduates. 

The late queen of Creole cooking, Leah Chase , was an alum. so was the first African-American female New Orleans police chief, Michelle Woodfork …

And judge for the Fifth Circuit Court of Appeals, Dana Douglas. Math teacher Michelle Blouin Williams told us Calcea and Ne'Kiya are typical St. Mary's students.  

Bill Whitaker: They're not unicorns.

Michelle Blouin Williams: Oh, no no. If they are unicorns, then every single lady that has matriculated through this school is a beautiful, Black unicorn.

Pamela Rogers: You're good?

Pamela Rogers, St. Mary's president and interim principal, told us the students hear that message from the moment they walk in the door.

Pamela Rogers: We believe all students can succeed, all students can learn. It does not matter the environment that you live in. 

Bill Whitaker: So when word went out that two of your students had solved this almost impossible math problem, were they universally applauded?

Pamela Rogers: In this community, they were greatly applauded. Across the country, there were many naysayers.

Bill Whitaker: What were they saying?

Pamela Rogers: They were saying, "Oh, they could not have done it. African Americans don't have the brains to do it." Of course, we sheltered our girls from that. But we absolutely did not expect it to come in the volume that it came.  

Bill Whitaker: And after such a wonderful achievement.

Pamela Rogers: People-- have a vision of who can be successful. And-- to some people, it is not always an African American female. And to us, it's always an African American female.

Gloria Ladson-Billings: What we know is when teachers lay out some expectations that say, "You can do this," kids will work as hard as they can to do it.

Gloria Ladson-Billings, professor emeritus at the University of Wisconsin, has studied how best to teach African American students. She told us an encouraging teacher can change a life.

Bill Whitaker: And what's the difference, say, between having a teacher like that and a whole school dedicated to the excellence of these students?

Gloria Ladson-Billings: So a whole school is almost like being in Heaven. 

Bill Whitaker: What do you mean by that?

Gloria Ladson-Billings: Many of our young people have their ceilings lowered, that somewhere around fourth or fifth grade, their thoughts are, "I'm not going to be anything special." What I think is probably happening at St. Mary's is young women come in as, perhaps, ninth graders and are told, "Here's what we expect to happen. And here's how we're going to help you get there."

At St. Mary's, half the students get scholarships, subsidized by fundraising to defray the $8,000 a year tuition. Here, there's no test to get in, but expectations are high and rules are strict: no cellphones, modest skirts, hair must be its natural color.

Students Rayah Siddiq, Summer Forde, Carissa Washington, Tatum Williams and Christina Blazio told us they appreciate the rules and rigor.

Rayah Siddiq: Especially the standards that they set for us. They're very high. And I don't think that's ever going to change.

Bill Whitaker: So is there a heart, a philosophy, an essence to St. Mary's?

Summer Forde: The sisterhood—

Carissa Washington: Sisterhood.

Tatum Williams: Sisterhood.

Bill Whitaker: The sisterhood?

Voices: Yes.

Bill Whitaker: And you don't mean the nuns. You mean-- (laughter)

Christina Blazio: I mean, yeah. The community—

Bill Whitaker: So when you're here, there's just no question that you're going to go on to college.

Rayah Siddiq: College is all they talk about. (laughter) 

Pamela Rogers: … and Arizona State University (Cheering)

Principal Rogers announces to her 615 students the colleges where every senior has been accepted.

Bill Whitaker: So for 17 years, you've had a 100% graduation rate—

Pamela Rogers: Yes.

Bill Whitaker: --and a 100% college acceptance rate?

Pamela Rogers: That's correct.

Last year when Ne'Kiya and Calcea graduated, all their classmates went to college and got scholarships. Ne'Kiya got a full ride to the pharmacy school at Xavier University in New Orleans. Calcea, the class valedictorian, is studying environmental engineering at Louisiana State University.

Bill Whitaker: So wait a minute. Neither one of you is going to pursue a career in math?

Both: No. (laugh)

Calcea Johnson: I may take up a minor in math. But I don't want that to be my job job.

Ne'Kiya Jackson: Yeah. People might expect too much out of me if (laugh) I become a mathematician. (laugh)

But math is not completely in their rear-view mirrors. This spring they submitted their high school proofs for final peer review and publication … and are still working on further proofs of the Pythagorean Theorem. Since their first two …

Calcea Johnson: We found five. And then we found a general format that could potentially produce at least five additional proofs.

Bill Whitaker: And you're not math geniuses?

Bill Whitaker: I'm not buying it. (laughs)
