10 Educational Search Engines for Students: From Homework to High-Quality Resources

Educational Search Engines are specialised search engines for finding scholarly and academic information. Students need to cite reputable sources for their research papers or other academic assignments. Usual search engines are good for navigating the vast internet. However, it becomes difficult to find reputable sources such as research papers and clinical trials.

The article mentions the top 10 educational search engines for students, such as Google Scholar, Google Books, Microsoft Academic, WorldWideScience, Educational Resources Information Center (ERIC), Virtual Learning Resources Center (VLRC), ResearchGate, PubMed Central, Infotopia, and Science.gov.

1. Google Scholar

Google Scholar was created by Google to create a database of scholarly literature from the web. Students can find different scholarly literature, such as peer-reviewed papers, theses, books, research papers, clinical trials, and discoveries from many different academic institutions and organisations.

2. Google Books

Google Books was created by Google to browse the index containing thousands of books from various authors and publications. You can search books using the title, author, publication, and ISBN number. It stores information such as reviews, where to buy, sample pages, and entire book information for certain books.

3. Microsoft Academic

Microsoft Academic was created by Microsoft for storing over 120 million publications in its database and allowing students to search scientific papers, research, journals, and conferences.

4. WorldWideScience

WorldWideScience is managed by the U.S. Department of Energy. It searches databases from more than 70 countries for academic resources. You can search for both English and translated academic resources.

5. Educational Resources Information Center (ERIC)

The Educational Resources Information Center (ERIC) is managed by the U.S. Department of Education. ERIC has over 1.3 million bibliographic educational literature.

6. Virtual Learning Resources Center (VLRC)

Virtual Learning Resources Center (VLRC) is an online index of academic resources. It is an alternative to Google Scholar. The index stores the websites reviewed by librarians and teachers on topics such as Art, Social sciences, Social Issues, and History.

7. ResearchGate

ResearchGate is a social networking website for scientists and researchers. It has over 11 million researchers who share their work. The users can share research papers, do projects together, find experts in a particular field, and ask questions.

8. PubMed Central

PubMed Central (PMC) is a free and open-access digital library of academic articles, such as medical research, clinical trials, and analytical studies. These resources are published in biomedical and life sciences journals. 

9. Infotopia

Infotopia is a free educational search engine optimized for students and teachers. It is based on Google searches and searches from websites reviewed by librarians and teachers. It covers various topics, such as Sci/Tech, Images, Games, Health, and mythology.

10. Science.gov

Science.gov is a free search engine that searches for information from 13 federal agencies, including the Department of Homeland Security, U.S. Geological Survey, Department of Transportation, Environmental Protection Agency, Government Publishing Office, National Aeronautics and Space Administration, and National Science Foundation. It has an index of over 2200 scientific websites and 70 scientific databases.

Final Words

Educational Search Engines for Students provide access to various academic resources to students, including research papers, medical studies, books, clinical trials, studies from scholars, and theses. The top 10 educational search engines include Google Scholar, Google Books, Microsoft Academic, Science.gov, PubMed Central, Researchgate, and others. Each search engine has its own index and database of academic resources and searches through them. 

Utilizing the internet effectively for college students involves discerning credible sources, leveraging online tools for research, and fostering digital literacy to maximize learning opportunities and academic resources.

Sat / act prep online guides and tips, the 5 best homework help websites (free and paid).

Other High School , General Education

Listen: we know homework isn’t fun, but it is a good way to reinforce the ideas and concepts you’ve learned in class. But what if you’re really struggling with your homework assignments?

If you’ve looked online for a little extra help with your take-home assignments, you’ve probably stumbled across websites claiming to provide the homework help and answers students need to succeed . But can homework help sites really make a difference? And if so, which are the best homework help websites you can use? 

Below, we answer these questions and more about homework help websites–free and paid. We’ll go over: 

• The basics of homework help websites
• The cost of homework help websites 
• The five best homework websites out there 
• The pros and cons of using these websites for homework help 
• The line between “learning” and “cheating” when using online homework help 
• Tips for getting the most out of a homework help website

So let’s get started! 

The Basics About Homework Help Websites–Free and Paid

Homework help websites are designed to help you complete your homework assignments, plain and simple. 

What Makes a Homework Help Site Worth Using

Most of the best sites allow users to ask questions and then provide an answer (or multiple possible answers) and explanation in seconds. In some instances, you can even send a photo of a particular assignment or problem instead of typing the whole thing out! 

Homework help sites also offer more than just help answering homework questions. Common services provided are Q&A with experts, educational videos, lectures, practice tests and quizzes, learning modules, math solving tools, and proofreading help. Homework help sites can also provide textbook solutions (i.e. answers to problems in tons of different textbooks your school might be using), one-on-one tutoring, and peer-to-peer platforms that allow you to discuss subjects you’re learning about with your fellow students. 

And best of all, nearly all of them offer their services 24/7, including tutoring! 

What You Should Should Look Out For

When it comes to homework help, there are lots–and we mean lots –of scam sites out there willing to prey on desperate students. Before you sign up for any service, make sure you read reviews to ensure you’re working with a legitimate company. 

A word to the wise: the more a company advertises help that veers into the territory of cheating, the more likely it is to be a scam. The best homework help websites are going to help you learn the concepts you’ll need to successfully complete your homework on your own. (We’ll go over the difference between “homework help” and “cheating” a little later!) 

You don't need a golden piggy bank to use homework help websites. Some provide low or no cost help for students like you!

How Expensive Are the Best Homework Help Websites?

First of all, just because a homework help site costs money doesn’t mean it’s a good service. Likewise, just because a homework help website is free doesn’t mean the help isn’t high quality. To find the best websites, you have to take a close look at the quality and types of information they provide! 

When it comes to paid homework help services, the prices vary pretty widely depending on the amount of services you want to subscribe to. Subscriptions can cost anywhere from $2 to $150 dollars per month, with the most expensive services offering several hours of one-on-one tutoring with a subject expert per month.

The 5 Best Homework Help Websites 

So, what is the best homework help website you can use? The answer is that it depends on what you need help with. 

The best homework help websites are the ones that are reliable and help you learn the material. They don’t just provide answers to homework questions–they actually help you learn the material. 

That’s why we’ve broken down our favorite websites into categories based on who they’re best for . For instance, the best website for people struggling with math might not work for someone who needs a little extra help with science, and vice versa. 

Keep reading to find the best homework help website for you! 

Best Free Homework Help Site: Khan Academy

• Price: Free!
• Best for: Practicing tough material 

Not only is Khan Academy free, but it’s full of information and can be personalized to suit your needs. When you set up your account , you choose which courses you need to study, and Khan Academy sets up a personal dashboard of instructional videos, practice exercises, and quizzes –with both correct and incorrect answer explanations–so you can learn at your own pace. 

As an added bonus, it covers more course topics than many other homework help sites, including several AP classes.

Runner Up: Brainly.com offers a free service that allows you to type in questions and get answers and explanations from experts. The downside is that you’re limited to two answers per question and have to watch ads. 

Best Paid Homework Help Site: Chegg

• Price: $14.95 to $19.95 per month
• Best for: 24/7 homework assistance  

This service has three main parts . The first is Chegg Study, which includes textbook solutions, Q&A with subject experts, flashcards, video explanations, a math solver, and writing help. The resources are thorough, and reviewers state that Chegg answers homework questions quickly and accurately no matter when you submit them.  

Chegg also offers textbook rentals for students who need access to textbooks outside of their classroom. Finally, Chegg offers Internship and Career Advice for students who are preparing to graduate and may need a little extra help with the transition out of high school. 

Another great feature Chegg provides is a selection of free articles geared towards helping with general life skills, like coping with stress and saving money. Chegg’s learning modules are comprehensive, and they feature solutions to the problems in tons of different textbooks in a wide variety of subjects. 

Runner Up: Bartleby offers basically the same services as Chegg for $14.99 per month. The reason it didn’t rank as the best is based on customer reviews that say user questions aren’t answered quite as quickly on this site as on Chegg. Otherwise, this is also a solid choice!

Best Site for Math Homework Help: Photomath

• Price: Free (or $59.99 per year for premium services) 
• Best for: Explaining solutions to math problems

This site allows you to t ake a picture of a math problem, and instantly pulls up a step-by-step solution, as well as a detailed explanation of the concept. Photomath also includes animated videos that break down mathematical concepts to help you better understand and remember them. 

The basic service is free, but for an additional fee you can get extra study tools and learn additional strategies for solving common math problems.

Runner Up: KhanAcademy offers in-depth tutorials that cover complex math topics for free, but you won’t get the same tailored help (and answers!) that Photomath offers. 

Best Site for English Homework Help: Princeton Review Academic Tutoring

• Price: $40 to $153 per month, depending on how many hours of tutoring you want 
• Best for: Comprehensive and personalized reading and writing help 

While sites like Grammarly and Sparknotes help you by either proofreading what you write via an algorithm or providing book summaries, Princeton Review’s tutors provide in-depth help with vocabulary, literature, essay writing and development, proofreading, and reading comprehension. And unlike other services, you’ll have the chance to work with a real person to get help. 

The best part is that you can get on-demand English (and ESL) tutoring from experts 24/7. That means you can get help whenever you need it, even if you’re pulling an all-nighter! 

This is by far the most expensive homework site on this list, so you’ll need to really think about what you need out of a homework help website before you commit. One added benefit is that the subscription covers over 80 other subjects, including AP classes, which can make it a good value if you need lots of help!  

Best Site for STEM Homework Help: Studypool

• Best for: Science homework help
• Price: Varies; you’ll pay for each question you submit

When it comes to science homework help, there aren’t a ton of great resources out there. The best of the bunch is Studypool, and while it has great reviews, there are some downsides as well. 

Let’s start with the good stuff. Studypool offers an interesting twist on the homework help formula. After you create a free account, you can submit your homework help questions, and tutors will submit bids to answer your questions. You’ll be able to select the tutor–and price point–that works for you, then you’ll pay to have your homework question answered. You can also pay a small fee to access notes, lectures, and other documents that top tutors have uploaded. 

The downside to Studypool is that the pricing is not transparent . There’s no way to plan for how much your homework help will cost, especially if you have lots of questions! Additionally, it’s not clear how tutors are selected, so you’ll need to be cautious when you choose who you’d like to answer your homework questions.  

What Are the Pros and Cons of Using Homework Help Sites?

Homework help websites can be a great resource if you’re struggling in a subject, or even if you just want to make sure that you’re really learning and understanding topics and ideas that you’re interested in. But, there are some possible drawbacks if you don’t use these sites responsibly. 

We’ll go over the good–and the not-so-good–aspects of getting online homework help below. 

3 Pros of Using Homework Help Websites 

First, let’s take a look at the benefits. 

#1: Better Grades Beyond Homework

This is a big one! Getting outside help with your studies can improve your understanding of concepts that you’re learning, which translates into better grades when you take tests or write essays. 

Remember: homework is designed to help reinforce the concepts you learned in class. If you just get easy answers without learning the material behind the problems, you may not have the tools you need to be successful on your class exams…or even standardized tests you’ll need to take for college. 

#2: Convenience

One of the main reasons that online homework help is appealing is because it’s flexible and convenient. You don’t have to go to a specific tutoring center while they’re open or stay after school to speak with your teacher. Instead, you can access helpful resources wherever you can access the internet, whenever you need them.

This is especially true if you tend to study at off hours because of your extracurriculars, work schedule, or family obligations. Sites that offer 24/7 tutoring can give you the extra help you need if you can’t access the free resources that are available at your school. 

#3: Variety

Not everyone learns the same way. Maybe you’re more of a visual learner, but your teacher mostly does lectures. Or maybe you learn best by listening and taking notes, but you’re expected to learn something just from reading the textbook . 

One of the best things about online homework help is that it comes in a variety of forms. The best homework help sites offer resources for all types of learners, including videos, practice activities, and even one-on-one discussions with real-life experts. 

This variety can also be a good thing if you just don’t really resonate with the way a concept is being explained (looking at you, math textbooks!).

Not so fast. There are cons to homework help websites, too. Get to know them below!

3 Cons of Using Homework Help Websites 

Now, let’s take a look at the drawbacks of online homework help. 

#1: Unreliable Info

This can be a real problem. In addition to all the really good homework help sites, there are a whole lot of disreputable or unreliable sites out there. The fact of the matter is that some homework help sites don’t necessarily hire people who are experts in the subjects they’re talking about. In those cases, you may not be getting the accurate, up-to-date, and thorough information you need.

Additionally, even the great sites may not be able to answer all of your homework questions. This is especially true if the site uses an algorithm or chatbot to help students…or if you’re enrolled in an advanced or college-level course. In these cases, working with your teacher or school-provided tutors are probably your best option. 

#2: No Clarification

This depends on the service you use, of course. But the majority of them provide free or low-cost help through pre-recorded videos. Watching videos or reading info online can definitely help you with your homework… but you can’t ask questions or get immediate feedback if you need it .

#3: Potential For Scamming 

Like we mentioned earlier, there are a lot of homework help websites out there, and lots of them are scams. The review comments we read covered everything from outdated or wrong information, to misleading claims about the help provided, to not allowing people to cancel their service after signing up. 

No matter which site you choose to use, make sure you research and read reviews before you sign up–especially if it’s a paid service! 

When Does “Help” Become “Cheating”?

Admittedly, whether using homework help websites constitutes cheating is a bit of a grey area. For instance, is it “help” when a friend reads your essay for history class and corrects your grammar, or is it “cheating”? The truth is, not everyone agrees on when “help” crosses the line into “cheating .” When in doubt, it can be a good idea to check with your teacher to see what they think about a particular type of help you want to get. 

That said, a general rule of thumb to keep in mind is to make sure that the assignment you turn in for credit is authentically yours . It needs to demonstrate your own thoughts and your own current abilities. Remember: the point of every homework assignment is to 1) help you learn something, and 2) show what you’ve learned. 

So if a service answers questions or writes essays for you, there’s a good chance using it constitutes cheating. 

Here’s an example that might help clarify the difference for you. Brainstorming essay ideas with others or looking online for inspiration is “help” as long as you write the essay yourself. Having someone read it and give you feedback about what you need to change is also help, provided you’re the one that makes the changes later. 

But copying all or part of an essay you find online or having someone write (or rewrite) the whole thing for you would be “cheating.” The same is true for other subjects. Ultimately, if you’re not generating your own work or your own answers, it’s probably cheating.

5 Tips for Finding the Best Homework Help Websites for You

Now that you know some of our favorite homework help websites, free and paid, you can start doing some additional research on your own to decide which services might work best for you! Here are some top tips for choosing a homework help website. 

Tip 1: Decide How You Learn Best 

Before you decide which site or sites you’re going to use for homework help, y ou should figure out what kind of learning style works for you the most. Are you a visual learner? Then choose a site that uses lots of videos to help explain concepts. If you know you learn best by actually doing tasks, choose a site that provides lots of practice exercises.

Tip 2: Determine Which Subjects You Need Help With

Just because a homework help site is good overall doesn’t mean that it’s equally good for every subject. If you only need help in math, choose a site that specializes in that area. But if history is where you’re struggling, a site that specializes in math won’t be much help. So make sure to choose a site that you know provides high-quality help in the areas you need it most. 

Tip 3: Decide How Much One-On-One Help You Need 

This is really about cost-effectiveness. If you learn well on your own by reading and watching videos, a free site like Khan Academy is a good choice. But if you need actual tutoring, or to be able to ask questions and get personalized answers from experts, a paid site that provides that kind of service may be a better option.

Tip 4: Set a Budget

If you decide you want to go with a paid homework help website, set a budget first . The prices for sites vary wildly, and the cost to use them can add up quick. 

Tip 5: Read the Reviews

Finally, it’s always a good idea to read actual reviews written by the people using these homework sites. You’ll learn the good, the bad, and the ugly of what the users’ experiences have been. This is especially true if you intend to subscribe to a paid service. You’ll want to make sure that users think it’s worth the price overall!

What’s Next?

If you want to get good grades on your homework, it’s a good idea to learn how to tackle it strategically. Our expert tips will help you get the most out of each assignment…and boost your grades in the process.

Doing well on homework assignments is just one part of getting good grades. We’ll teach you everything you need to know about getting great grades in high school in this article.

Of course, test grades can make or break your GPA, too. Here are 17 expert tips that’ll help you get the most out of your study prep before you take an exam.

5 best search engines for students in 2022 besides Google

How often do you Google information? One of the best search engines in the world is indispensable to our daily lives, especially for university students swamped with course readings and assignments. A few keywords in the search bar — and voilà — the results link you to endless facts and suggestions on a particular topic.

Google might win the popular vote, but it’s far from the only resource on the internet for aspiring scholars. How you find sources for assignments matters just as much as the information you get. For that, there’s no better way to dive into your subject through search engines optimised for academic research — it’s part of developing your critical thinking skills while sharpening your eyes on fact-checking to spot fake news .

If you’re ready to up your searching game, make sure to bookmark this list for future references:

Best search engines to use in academia 

Worldcat.org.

If you’re familiar with Google Scholar or JSTOR, you might’ve encountered this nifty website through your university library. WorldCat.org prides itself on being the world’s largest network of library content and services.

You can use WorldCat.org through your student library account to unlock an endless treasure trove of knowledge. It works by directing you to collections of more than 10,000 libraries globally, including the prestigious Bodleian Library at the University of Oxford and The Library of Congress.

WorldCat.org grants you access to various formats in its catalogue, such as old VHS tapes and downloadable musical scores — all of which are primary sources that enhance your research quality considerably.

Semantic Scholar

Need a more precise and analytical method to interpret your sources? Semantic Scholar is your answer.

Powered by the Allen Institute for Artificial Intelligence (AI), this free search engine harnesses sophisticated AI and machine learning techniques to augment its discovery tools. It has a function that extracts meaning and connects the dots between papers, so it’s handy for data interpretation.

You can also say goodbye to confusion in navigating advanced search tools and wordy texts on the screen. Visually, it’s one of the best academic search engines with a user-friendly interface that uses a simple but vibrant design. The easy-to-follow tutorials are a plus to help you maximise your search on the website.

Would you like to plant a tree with every search? Ecosia ‘s unique philosophy lands it on our best search engines list: it’s a social business founded on the principle that everyone can combat climate change, even with a click.

Ecosia channels the ad revenue it makes to support reforestation projects that aim to neutralise carbon dioxide emissions. According to the website, it has planted over 154 million trees worldwide, from Mount Bamboutos in Cameroon to restoring Indonesian forests in former oil plantations.

Its green initiatives aside, Ecosia is ideal for students as it can be added as extensions to default browsers, with an app version for your mobile devices. Environmental sciences students can rejoice: its blog regularly updates the latest scoop in the eco world, so you’re always in the loop on current climate action news.

Ecosia uses revenue from ads to support reforestation projects worldwide, and can be easily added as an extension on your default browser. Source: Nipah Dennis/AFP

Open Knowledge Maps

Scientific journals don’t have to be dry and dull, and developers of this search engine astutely understand the power of visual learning. Instead of getting results in lines of text, it gives you a map with an overview of the 100 most relevant documents related to your search query. The algorithm then groups them together in circles based on the number of common words they have.

It’s one of the best search engines vetted by researchers from prestigious schools like ETH Zurich and Harvard University. The best part? There’s an automatic citation generator for each document you click on, saving you time when formatting your references correctly.

COnnecting REpositories (CORE)

CORE is a not-for-profit service with the aim of becoming the world’s largest aggregator of open-access journals and peer-reviewed papers on the web. It has over 200 million scholarly articles gathered from 11,000 data providers, connecting you with multiple research repositories from universities across the world. 

If you’re tired of pesky paywalls blocking access to papers you need, you can add the CORE Discovery extension to either Google Chrome, Mozilla Firefox, or Opera for free. This handy feature searches for an accessible copy elsewhere, so you don’t have to scramble for it on your own.

15 Educational Search Engines College Students Should Know About

By Anna Heinrich on 03/22/2017

After hours spent scrolling through Google and pulling up endless clickbait results, you’re frustrated with the internet. You have a paper to write, homework to do and things to learn—and this degree isn’t going to earn itself. You know you won’t get away with citing Wikipedia or Buzzfeed in your research paper. Even the big news engines aren’t scholarly enough. You need reputable sources for your homework, and you need them now.

With so many resources online, it’s hard to narrow it down and find ones that are not only reliable and useful, but also free for students. We’ve saved you the time and picked out our 15 best free search engines for research.

15 Scholarly search engines every student should bookmark

1. google scholar.

Google Scholar was created as a tool to congregate scholarly literature on the web. From one place, students have the ability to hunt for peer-reviewed papers, theses, books, abstracts and articles from academic publishers, professional societies, preprint repositories, universities and other scholarly organizations.

2. Google Books

Google Books allows web users to browse an index of thousands of books, from popular titles to old, to find pages that include your search terms. Once you find the book you are looking for, you can look through pages, find online reviews and learn where you can get a hard copy.

3. Microsoft Academic

Operated by the company that brings you Word, PowerPoint and Excel, Microsoft Academic is a reliable, comprehensive research tool. The search engine pulls content from over 120 million publications, including scientific papers, conferences and journals. You can search directly by topic, or you can search by an extensive list of fields of study. For example, if you’re interested in computer science, you can filter through topics such as artificial intelligence, computer security, data science, programming languages and more.

4. WorldWideScience

WorldWideScience , which refers to itself as “The Global Science Gateway,” is operated by the Office of Scientific and Technical Information—a branch of the Office of Science within the U.S. Department of Energy. The site utilizes databases from over 70 countries. When users type a query, it hits databases from all over the world and will display both English and translated results from related journals and academic resources.

5. Science.gov

Science.gov is operated and maintained by the Office of Science and Technical Information, the same department that collaborates on WorldWideScience.org. This search engine pulls from over 60 databases, over 2,200 websites and 200 million pages of journals, documents and scientific data. Search results can be filtered by author, date, topic and format (text or multimedia).

6. Wolfram Alpha

A self-described “computational knowledge engine,” Wolfram Alpha does not so much provide search results as it does search answers. Simply type in a topic or question you may be interested in, such as, “What is the function of the pancreas?” and the answer will show up without making you scroll through pages of results. This is especially handy for those in need of math help.

With its minimalist design, Refseek doesn’t look like much. However, the engine pulls from over one billion web pages, encyclopedias, journals and books. It is similar to Google in its functionality, except that it focuses more on scientific and academic results—meaning more results will come from .edu or .org sites, as well as online encyclopedias. It also has an option to search documents directly—providing easy access to PDFs of academic papers.

8. Educational Resources Information Center

Populated by the U.S. Department of Education, the Educational Resources Information Center (ERIC) is a great tool for academic research with more than 1.3 million bibliographic records of articles and online materials. ERIC provides access to an extensive body of education-related literature including journal articles, books, research syntheses, conference papers, technical reports, policy papers and more. With more than eight million searches each month, it’s no wonder why this search engine is a great web source for education.

9. Virtual Learning Resources Center

The Virtual Learning Resources Center (VLRC) is an online index hosting thousands of scholarly websites, all of which are selected by teachers and librarians from around the globe. The site provides students and teachers with current, valid information for school and university academic projects using an index gathered from research portals, universities and library internet subject guides recommended by teachers and librarians.

iSeek is a great search engine for students, teachers and administrators alike. Simply ask a question or enter search topics or tools, and iSeek will pull from scholastic sources to find exactly what you are looking for. The search engine is safe, intelligent and timesaving—and it draws from trusted resources from universities, government and established non-commercial sites.

11. ResearchGate

ResearchGate is a unique social networking site for scientists and researchers. Over 11 million researchers submit their work, which totals more than 100 million publications, on the site for anyone to access. You can search by publication, data and author, or you can even ask the researchers questions. Though it’s not a search engine that pulls from external sources, ResearchGate’s own collection of publications provides a hearty selection for any inquisitive scholar.

The Bielefeld Academic Search Engine (BASE) prides itself as being “one of the world’s most voluminous search engines especially for academic web resources.” Utilizing 4,000 sources, the site contains results from over 100 million documents. The advanced search option allows users to narrow their research—so whether you’re looking for a book, review, lecture, video or thesis, BASE can provide the specific format you need.

13. Infotopia

Infotopia describes itself as a “Google-alternative safe search engine.” The academic search engine pulls from results that have been curated by librarians, teachers and other educational workers. A unique search feature allows users to select a category, which ranges from art to health to science and technology, and then see a list of internal and external resources pertaining to the topic. So if you don’t find what you’re looking for within the pages of Infotopia, you will probably find it in one of its many suggested sites.

14. PubMed Central

This site is perfect for those studying anything related to healthcare or science. PubMed Central is operated by the National Center for Biotechnology Information, a division of the U.S. National Library of Medicine. The database contains more than 3 million full-text journal articles. It’s similar to PubMed Health , which is specifically for health-related research and studies, and includes citations and abstracts to more than 26 million articles.

15. Lexis Web

Researching legal topics? Lexis Web is your go-to for any law-related inquiries you may have. The results are drawn from legal sites, which can be filtered by criteria such as news, blog, government and commercial. Users can also filter results by jurisdiction, practice area, source and file format.

Start searching

Pulling up an Internet search might be second nature to you by now. But a little forethought into where you begin your hunt can make your life much easier. Save yourself the time wading through basic Google search results and utilize some of these tools to ensure your results will be up to par with academic standards.

Google’s search tools can help with your homework.

Focused on STEM

Google has become invaluable to students and teachers, especially with remote learning becoming a necessity all around the world. Despite some of their shortcomings , the company's tools are generally incredibly helpful, and now, Google has highlighted  a few more education-focused features in its core product Search.

Google has added over 2000 STEM (Science, technology, engineering, and mathematics) concepts to its results, giving you easy and fast access to educational overviews of topics such as " chemical bonds ." The overview provides details on types, examples, practice problems, worksheets, and calculators. The STEM resources and the practice problems have been available on desktops for a while following a smaller redesign , but it looks like Google is only making them more widely available in the US now. Google has also re-introduced its AR 3D models of chemistry, biology, physics, and anatomy concepts, which have been available on phones for a while now . And if you're stuck on math problems during homework, you can ask Google Lens for help.

For the next few weeks, Google has another neat new option planned. It wants to help with complicated STEM questions such as " 0.50 moles of NaCI are dissolved in 2.5 L of water, what is the molarity? " You'll be able to punch questions like this into Google Search, which will help you with detailed explanations and provide you with similar questions for practice.

While the announcement doesn't bring too many new things to the table, it's great to see Google reiterating its focus on education. That's right in line with recent adjustments to the parental supervision tool Family Link and child accounts.

Homework: how to make the most of search engines.

| February 24, 2020 | 0 responses

But these skills  are not acquired  automatically by spending more time surfing the web. On the contrary, students need  explicit advice  and  instructions  to be able to do more effective research.

Young people tend to think that they have  already mastered  these tools. Their  teachers  and  parents  assume this too. This assumption is often coupled with the  mistaken belief  that all research is bound to be fruitful. And while digital tools are often integrated into classroom research, we rarely focus on learning the research methods themselves.

Many  teachers do not explicitly guide their students in their online research. On the contrary, children often form  by themselves  and are reluctant to ask for help. This does not allow them to acquire the necessary skills.

For six years, I studied how  young people  use search engines. Among the groups I have followed, whether they are studying in a traditional establishment or studying at home, there are a number of bad habits.

For example, everyone spends far more time on sites that are not relevant than on quality sites that would be really useful to them. And, quite often, they give up searching until they find the information they need.

Here are three things to keep in mind to really benefit from online research.

Expand your queries

Young people should explore, synthesize and question information found on the Internet, rather than just spot it, and move on. Search engines offer endless learning possibilities, but students tend to  focus  on a few specific points. This does not allow them to achieve better results than they would have had forty years ago in a printed encyclopedia.

It is important to use different keywords and cross search queries, sites and search tabs, especially news or images.

Part of my thesis work (being written) consisted of observing young people and their parents using a search engine for 20 minutes. In one of these sessions (the situation is quite typical), a family practicing school at home typed in the Google search bar: “How many endangered tigers are there in Sumatra” . They then click on a single site, on which they locate an explanatory sentence.

The parent copies this response and goes on to the next subject: growing seeds. The research would have been much richer if they had also asked themselves:

• where is Sumatra
• why tigers are in danger
• how we can contribute to their protection

I did my own research with the keywords “Sumatran tigers” in quotes. The results obtained allowed me to see images of tigers in National Geographic and to chat live with an expert from the World Wide Fund (WWF).

By clicking on the “news” tab from the same query, you get a review of recent articles, from the arrival of two tigers in a nature reserve in  Australia  to the  effects  of palm oil on the species . It may be enough to modify your queries a little to improve the educational benefits of a search.

Take your time

Too often, it is assumed that research is a rapid process. Families in my study spent an average of 90 seconds or less visiting each website and engaging in new topics every 4 minutes.

With such speed, it can be assumed that students are not making  effective requests  or getting the information they really need. They may also not have enough time to  review  the search results and  assess the suitability  of the sites offered.

My research confirms that  budding investigators  tend to click on the most prominent links, often the first sites listed, most likely to save time. This is problematic in a commercial environment where the referencing of a site can be bought, and in a context where children  tend to  take for granted everything they find online.

A quick search  is not in itself problematic. By quickly locating the necessary information, students can devote more time to other more complex tasks, such as analyzing and analyzing the facts they find. But this is only true if they have indeed obtained the elements they need.

Do not rely too much on Google

Children  often rely  on tools offered by Google such as the “Did you mean” function (editor’s note: which corrects queries supposed to contain typos).

When students say they are confident in their ability to search online, my thesis work shows that they trust Google even more. “I’m used to Google making the necessary corrections,” said one of them.

Such attitudes can lead them to reject relevant keywords, by automatically accepting self-correction (sometimes erroneous) or by leaving on irrelevant tracks.

Teaching students to select the sites consulted based on domain name extensions can help them feel responsible for their research instead of downloading to the tool. For example, the extension “.com”, easy to buy, refers more frequently to a commercial site while the extensions “.gouv” or “.edu”, corresponding to official sites, ensure a certain reliability.

Search engines have  great  educational  potential  , but we must be  careful  and avoid  shortcuts  , and not believe that this potential is a guarantee.

CSE 163, Spring 2020: Homework 4: Python Classes and Search Engines

At a high-level, a search-engine is an algorithm that accepts a query from the user, and computes how relevant a given document is to that query. The search engine can then rank documents according to their relevance.

In this assignment you will implement your own search engine by defining two classes, Document and SearchEngine . The Document class represents a single file in the search engine, and the SearchEngine class handles the functionality of querying the collection of stored Document s. The SearchEngine will use the TF-IDF (term frequency - inverse document frequency) algorithm to compute the relevance of a document to a given term.

The purpose of this assignment is to introduce you to writing cohesive python classes. This will include public methods, private methods, and data structures stored as fields. Additionally, you will work with common indexing algorithms, and consider efficient ways to store data that will be frequently accessed by the TF-IDF algorithm.

You will probably find that this is the most challenging assignment of the whole quarter. This is intended since it is the last assignment that you will be doing without working on your project in parallel. The remaining assignments won't be as complex as this one so it's okay to feel a bit lost the first time you read over this spec. There are a lot of instructions and it gives guidance on how to develop this assignment in parts to this complexity.

Learning Objectives

After this homework, students will be able to:

• Write a complete Python class from scratch.
• This will include writing two classes which interact with each other.
• Implement basic Python classes to represent Documents and SearchEngines .
• Identify appropriate data structures to store/access term indexes efficiently.
• Understand fundamental document and term ranking algorithms to implement a basic search engine.
• Specifically the TF-IDF algorithm which computes term-frequency and inverse document frequency.

Expectations

Here are some baseline expectations we expect you to meet:

Follow the course collaboration policies

The files included are:

• main.py : A python file which will allow a user to run a new search engine at the command line. More information about this file is included later in the specification.
• small-wiki : This directory contains a smaller number of wikipedia files, and your SearchEngine can be used to query and rank the files.
• wikipedia : This directory contains a number of wikipedia files, and your SearchEngine can be used to query and rank the files. This directory is too large for Ed so it is only provided locally for you to try out for fun.
• hw4_test.py : The file you should put your tests for document.py and search_engine.py in.
• cse163_utils.py : A file where we will store utility functions for helping you write tests.

If you are working locally, you should download the starter code hw4.zip and open it as the project in Visual Studio Code.

If you are developing on Ed, you don't need to download anything. An important thing to note, is that on Ed the small-wiki directory is stored at the path /course/small-wiki .

The Algorithm

To implement the document ranking algorithm you will use the TF-IDF (term frequency- inverse document frequency) algorithm. This is just a fancy way of weighting documents based on their relevance to a search term. TF-IDF is one of the most popular term-weighting schemes - 83% of text-based recommender systems use TF-IDF.

The TF-IDF algorithm consists of two main computations. The following information describes these computations at a high-level, and the exact equations will be included later in the spec.

Term Frequency

The term frequency is computed on a document level, and it represents how often a search term appears in a specific document.

Inverse Document Frequency

Because filler words such as “the” are so common, term frequency tends to incorrectly weight documents that use the word “the” often. The inverse document frequency is a measure of how often the word appears in the entire set of documents. We then use this value to diminish the weight of terms that occur very frequently.

Optional: TF-IDF

You are only required to understand the information about the algorithm covered in the spec. For those interested, more information about TF-IDF can be found here .

Part 0: The Document Class

The Document class represents a single file in the SearchEngine , and will include functionality to compute the term frequency of a term in the document. Your Document class should have the following methods:

• An initializer that takes a path to a document (described in "Constructing a Document").
• A function named get_path that returns the path of the file this Document represents.
• A function named term_frequency that returns the term frequency of a given term (described in "Term Frequencies").
• A function named get_words that returns the list of the unique words in the document (described in "Getting the Words").

Part 0 Expectations

• You should create and implement a python file called document.py
• For this part of the assignment, you may import and use the re module (the use of re will be described later in the spec), but you may not use any other imports.
• Your field(s) in this class should be private.

Constructing a Document

The initializer for the Document class should take a single file name as an argument. A new Document should be created to manage the terms in the original file. If the given file is empty, the Document that is constructed should represent an empty file. You may assume the given string represents a valid file.

Precomputing

Computing the information described in the following sections (e.g., term_frequency ) for a document is a relatively inefficient process. We must iterate over the entire document to calculate the frequency of a single word. To make this process more efficient we should pre-compute the term frequencies of a document. The initializer should construct a dictionary which maps from terms (string) to their frequency in the document (floats). This will make sense after reading about the other methods you need to implement.

When you are constructing your dictionary of terms, all terms should be case insensitive and ignore punctuation. This means that “corgi” , “CoRgi” , and “corgi!!” are all considered the same term. You can use the following regular expression to remove punctuation from a string: token = re.sub(r'\W+', '', token) This will remove all punctuation from the string stored in token. You must import the re module to use this regular expression.

Term Frequencies

The term frequency of a term in a document is defined as:

Therefore, if we had a document

Then the frequencies for the given document would be

Write a function called term_frequency that takes a term as a parameter and returns the term-frequency of the given term in the document. This function should not do any actual computation, but instead use the pre-computed dictionary from the initializer. If the given term does not exist in the document, the function should return 0. If using the example above, doc.term_frequency('dog') should return 0.25.

The term_frequency function should be case-insensitive, and remove punctation from the given word, using the regular expressions defined in the initializer.

Getting the Words

Write a function get_words which returns a list of all the words in this document. If there are duplicate words in the document they should only appear in the list once. The words returned should the words in the file after our pre-processing described in the spec (lowercase and stripped of punctuation).

Note: You should not re-read the file in this method to compute the words list.

Thinking forward to Part 3 , you can now start thinking about testing your Document class to gain confidence your solution is correct. This is a good idea to start now so you can identify any bugs here, rather than trying to find them when implementing the SearchEngine .

At this point, your Document is fully completed. This means you should be able to compute some term-frequencies for small files you create and test any behaviors of this class described here.

Part 1: The SearchEngine Class (single word queries)

The SearchEngine class will manage a collection of Documents , and handle computing the relevance of a Documents to a given term. To do this, the SearchEngine will compute the TF-IDF of a given term for each Document which contains the term.

Part of the development strategy for implementing search_engine.py is building the solution up in parts. In Part 1, you will implement a search_engine.py that supports only single-word queries. In Part 2, you will extend this to support multi-word queries.

Part 1 Expectations

• You should create and implement a python file called search_engine.py
• For this part of the assignment, you may import and use the math , os , and re modules as well as the document module you wrote for Part 0, but you may not use any other imports.

Important Note

We highly recommend reading the entire search_engine.py (single word query) spec, and understanding the algorithm for ranking documents before implementing. It will be challenging to implement the necessary data structures without understanding the context for how they will be used in the search function.

Constructing a SearchEngine

The SearchEngine initializer should take a directory name (string), and construct an inverse index representing all documents in the given directory. You may assume that the given string represents a valid directory, and that the directory contains only valid files. Your SearchEngine should not reimplement any behavior that is already implemented in the Document class.

Iterating over a Directory

The os.listdir() function will return a list of all the files and directories in a given directory.

You will use something very similar in your SearchEngine initializer. Each file that is returned by the os.listdir() is represented as only the file name. However, when you pass the file name into the Document initializer, it will try to open the file based on its name. Since the file is in a different directory, the Document will not be able to open the file. To avoid this, we must pass the path of the file to the Document initializer. Since the directory containing the file will be in the same directory as the Document class, we can pass the directory_name + '/' + file_name to the Document initializer. The directory_name is just the string passed to the SearchEngine initializer.

For Mac Users

Macs sometimes create hidden files named .DS_Store that can cause your code to break since they aren't valid text files. One option is to make sure to delete this file. Another option is you are allowed to put a special condition in your code to ignore any files that start with a '.' . You may assume no valid file starts with a '.' . For example, you could write something like:

Inverse Index

When you implement the search function it will be necessary to find all documents which contain the given search term. It is inefficient to iterate over each document in the SearchEngine and check if it contains a given word. Instead, the initializer for SearchEngine should pre-compute an inverse index . An inverse index is just a fancy term for a dictionary which maps from a term (string) to a list of Documents which contain that term. The visualization below describes what the inverse index should look like for a few example documents.

When you are constructing the inverse index in SearchEngine , you should avoid re-implementing any behavior that the Document can provide for you.

Calculating the IDF

Write a function _calculate_idf which takes a term as a string argument and returns the score for that term over all documents managed by the SearchEngine . The IDF represents the inverse document frequency, and is the inverse of the proportion of documents in the SearchEngine that contain the given term. The IDF should be calculated as follows:

Where \( ln \) is the natural logarithm. This can be computed using the log function in the math module.

Note: _calculate_idf is a private function, which will not be used directly by the client. Because it's defined in the SearchEngine class, you should use it to help you implement the search function. We will expect that you have this private function with the behavior described so that we can test your code. As mentioned in lecture, it's generally a bad practice for clients to look at private functions, but we are making an exception for our tests so we can better test your code.

The Search Function

Write a function search which takes a string as an argument and returns a list of document names. The documents should be sorted in descending order of TF-IDF . If no document in your SearchEngine contains the term, the function should return None . The search function should be case-insensitive, and ignore any punctuation in the given term.

The TF-IDF for term t on document D is defined as

To generate a ranked list of documents

• Compute the TF-IDF score for each document that contains the given term. You will probably want to store these scores in a list of tuples each containing the name of the document and its score.
• Sort the documents in descending order of TF-IDF.
• Return the document names as a list.

Search Example

It will help to understand a full-example of what the search algorithm should return for an example corpus. Consider we had the following three files in a directory test-files (shown as file name / content pairs). Notice these documents are slightly different than the last part.

• test-files/doc1.txt : Dogs are the greatest pets.
• test-files/doc2.txt : Cats seem pretty okay.
• test-files/doc3.txt : I love dogs!

Then, if we were to search for the term 'dogs' , the search algorithm would follow the following steps:

• Find all the documents that contain the word 'dogs' . In this case, the relevant files are test-files/doc1.txt and test-files/doc3.txt .
• Compute TF-IDF for 'dogs' in test-files/doc1.txt , which in this example is 0.081 . This is because the IDF of the term 'dogs' in the corpus is math.log(3/2) and the TF of the term 'dogs' in test-files/doc1.txt is 1/5 .
• Compute TF-IDF for 'dogs' in test-files/doc3.txt , which in this example is 0.135 . This is because the IDF of the term 'dogs' in the corpus is math.log(3/2) and the TF of the term 'dogs' in test-files/doc3.txt is 1/3 .
• We recommend storing this in a list of tuples so we can sort it in the next step. In this example, this list would look like [('test-files/doc1.txt', 0.081), ('test-files/doc3.txt', 0.135)] .
• Then we sort the tuples so they are sorted by TF-IDF in descending order. In this example, this sorted list would look like [('test-files/doc3.txt', 0.135), ('test-files/doc1.txt', 0.081)] .
• Then we can return the result ['test-files/doc3.txt', 'test-files/doc1.txt'] .

Thinking forward to Part 3 , you can now start thinking about testing your SearchEngine class to gain confidence your solution is correct. This is a good idea to start now so you can identify any bugs here, rather than trying to find them when implementing the multi-word queries in SearchEngine .

At this point, your SearchEngine is complete enough to run a query with a single term in it. It is hard to make a test on the entire wikipedia dataset (since you don't know what the expected answer is), so making a test-case for the example shown above would be a great starting point!

Part 2: The SearchEngine Class (multi-word queries)

Now that you have implemented the SearchEngine , we want to extend the search function to support multi-word queries . Note that you should only need to change the search function of your SearchEngine class implemented in Part 1.

Multi-Word Queries

To compute the TF-IDF of a multi-word query, we compute the TF-IDF for each individual term in the query and then sum these terms to compute the total TF-IDF .

For example, if the query was “a cute dog”, the TF-IDF of the query for document D would be

Similar to part 1, we compute the TF-IDF for each document that contains a term in the query and sort the documents by descending order of TF-IDF .

Finding Relevant Documents

However, finding the relevant documents for a multi-word query is a bit more challenging. Instead of looking at a single entry in the dictionary, we must look at all Documents which contain at least one word in the query. This means if the query is “a cute dog” the TF-IDF should be computed for all documents in the SearchEngine that contain the word “a”, all documents that contain the word “cute”, and all documents that contain the word “dog”. Even if a document only contains the word “a”, it should still be included in the ranking - its ranking will just be lower because its TF-IDF score for “cute” and “dog” will be 0.

Part 3: Testing and Running the Search Engine

Now that you have implemented a SearchEngine that supports mulit-word queries, you can use it to query directories full of text documents!

Running the Search Engine Locally

main.py is a program for running your SearchEngine that we have implemented for you. It can be run in VS Code just like any other python program (Right-click -> “Run Python File in Terminal”). When run, main.py will output a series of prompts to the console, which allow the user to input the directory to be searched, and then enter search terms.

We have included a directory called wikipedia in hw4.zip which contains a large number of HTML wikipedia pages. You can run main.py and enter wikipedia as the directory. Note that it will take a few minutes for the SearchEngine to be constructed because there are so many files. You can also use small-wiki as a smaller example.

You can now query terms over Wikipedia files! Note how fast the ranking is for terms you have searched. Even though the number of documents is HUGE. Since you precomputed all of the values, computing a document ranking is very fast.

Running the Search Engine on Ed

You can run the search engine with the Run button. The wikipedia directory included for the people running locally is too large for Ed. Instead, you should use small-wiki . The directory for small-wiki can be found at /course/small-wiki .

You will also need to test your document.py and search_engine.py classes. We have included a file called hw4_test.py where you should write your tests.

You should write three tests for document.py and three tests for search_engine.py . Each call to assert_equals counts as a single test. Testing these classes will require you to create your own test corpus since it would be too much work for you to find the expected output to use for the wikipedia dataset. To test each class you can construct a new instance of the class and pass in your own custom documents. Then you can call the functions of the class and verify that the returned value matches what you expected.

Since the SearchEngine reads documents from a folder, to test it you will likely need to create your own directories containing files in your hw4 directory. You should include these test document directories in your submission so we can run your tests.

Recall on Ed, you will need to specify the paths to these directories with an absolute path (e.g. /home/test-dir if you uploaded test-dir ).

As in previous homeworks, we have provided a function called assert_equals that takes an expected value and the value returned by your function, and compares them: if they don't match, the function will crash the program and tell you what was wrong. You can see more instructions an example for tests from the Homework 1 - Part 1 to see examples of how to call the tests.

Similar to the previous homeworks, the assert_equals lives in a file called cse163_utils.py .

Part 3 Expectations

For full credit, your hw4_test.py must satisfy all of the following conditions:

• Use your own test data files just like in HW2. Make sure to turn them in as well!
• Uses the main method pattern shown in class.
• Has functions to separate the tests for Document and the tests for SearchEngine .
• Each of these test functions should have a descriptive name that indicates which function is being tested (e.g. test_funky_sum )
• Each of the test functions must be called from main.

Your submission will be evaluated on the following dimensions

• Your solution correctly implements the described behaviors. You will not have access to all of the staff tests when you turn in your assignment. All behavior we test is completely described by the problem specification or shown in an example.
• When we run your code, it should produce no errors or warnings.
• You should remove any debug print statements. Some students report Ed crashing when they try to print the whole dataset; remove those extra print statements to prevent excessive output.
• All code files submitted pass flake8 .
• Your program should be written with good programming style. This means you should use the proper naming convention for methods, variables, and fields ( snake_case ) and for classes ( CapitalCase ). Your code should not be overly redundant and should avoid unnecessary computations.
• Each class you write should also have a doc-string format
• There is a doc-string at the top of each code file you write with your name, section, and a brief description of what that program does.
• The fields of all your classes should be private (by having the names start with a _ ) . In general, you should not access the fields of a object outside of the class definition itself. The one general exception to this rule is that you are allowed to access the fields directly in your tests. Because your tests are something you wrote personally and serve the purpose of verifying the correctness of your program, they don't need to behave like a true client should.
• Any expectations in the subsections listed above are met.

A note on allowed material

A lot of students have been asking questions like "Can I use this method or can I use this language feature in this class?". The general answer to this question is it depends on what you want to use, what the problem is asking you to do and if there are any restrictions that problem places on your solution.

There is no automatic deduction for using some advanced feature or using material that we have not covered in class yet, but if it violates the restrictions of the assignment, it is possible you will lose points. It's not possible for us to list out every possible thing you can't use on the assignment, but we can say for sure that you are safe to use anything we have covered in class so far as long as it meets what the specification asks and you are appropriately using it as we showed in class.

For example, some things that are probably okay to use even though we didn't cover them:

• Using the update method on the set class even though I didn't show it in lecture. It was clear we talked about sets and that you are allowed to use them on future assignments and if you found a method on them that does what you need, it's probably fine as long as it isn't violating some explicit restriction on that assignment.
• Using something like a ternary operator in Python. This doesn't make a problem any easier, it's just syntax.

For example, some things that are probably not okay to use:

• Importing some random library that can solve the problem we ask you to solve in one line.
• If the problem says "don't use a loop" to solve it, it would not be appropriate to use some advanced programming concept like recursion to "get around" that restriction.

These are not allowed because they might make the problem trivially easy or violate what the learning objective of the problem is.

You should think about what the spec is asking you to do and as long as you are meeting those requirements, we will award credit. If you are concerned that an advanced feature you want to use falls in that second category above and might cost you points, then you should just not use it! These problems are designed to be solvable with the material we have learned so far so it's entirely not necessary to go look up a bunch of advanced material to solve them.

tl;dr; We will not be answering every question of "Can I use X" or "Will I lose points if I use Y" because the general answer is "You are not forbidden from using anything as long as it meets the spec requirements. If you're unsure if it violates a spec restriction, don't use it and just stick to what we learned before the assignment was released."

This assignment is due by Thursday, May 7 at 23:59 (PDT) .

You should submit your finished document.py , search_engine.py , and hw4_test.py on Ed .

DO NOT submit the wikipedia dataset.

Conquering Assignments: A Guide to Homeworkify and its Alternatives

Posted by: BlueStacks Content Team

Editor’s Rating:

May 27, 2024

Homework can be a double-edged sword. It reinforces learning but can also feel like a relentless uphill battle. Fear not, this blog tackles both Homeworkify, a popular homework help platform, and explores 16 alternatives to suit your learning style and budgetary needs.

Homeworkify: Unblurring the Path to Solutions

Launched in 2016, Homeworkify has become a popular destination for students seeking help with assignments. It functions as a search engine for homework solutions, crawling the web to find answers to student queries. Here’s a breakdown of what Homeworkify offers:

• Free Chegg Answers: One of its key features is the ability to access answers from Chegg, a subscription-based platform, for free. You can simply paste the question URL or type your question directly into Homeworkify’s search bar. This can be a game-changer for students who cannot afford Chegg’s subscription fees.
• Subject Variety: Homeworkify covers a wide range of subjects, including Mathematics (from basic Algebra to Calculus), Science (Biology, Chemistry, Physics), English Literature, History, Business courses (Finance, Accounting, Marketing), and more.
• Potential Learning Tool: Used strategically, Homeworkify can be a helpful resource to understand concepts by providing explanations alongside answers. Some solutions incorporate step-by-step breakdowns or visuals, aiding in grasping the thought process behind solving a problem.

Remember: While free access to solutions can be tempting, it’s crucial to use Homeworkify as a learning aid, not a shortcut. Here are some things to keep in mind:

• Source Reliability: The reliability of the answers found by Homeworkify can vary depending on the source. It’s important to critically evaluate the information you find. Double-check the solutions and explanations against your textbook or class notes, and consult with teachers or tutors if you have doubts.
• Learning vs Copying: While Homeworkify can be a helpful resource for understanding concepts, it’s important to focus on understanding the underlying principles behind the answers. Just copying answers won’t help you learn in the long run and may hinder your ability to tackle similar problems in the future.

Introducing Homeworkify: Your Free Homework Help Companion

It boasts a user-friendly platform where you can find solutions and comprehensive explanations for a wide range of subjects.

‘Furiosa: A Mad Max Saga’ Review: George Miller Paves the Way for ‘Fury Road’ with One of the Greatest Prequels Ever Made

Whatever dim but undying hope that Furiosa still maintained for the future would have to be seeded in the same barren Wasteland that had sucked her entire life dry; twice denied the utopia that had been promised to her, Furiosa would have to return to the Citadel from which she had just escaped and claim it for herself. There is no going back, but sometimes you can only find the path forward by looking in the rear-view mirror. Related Stories ‘Godzilla Minus One’ Is Now on Netflix and VOD, With No Advance Notice IATSE Pauses Negotiations on Area Standards Agreement Without a Deal, but Will Pivot Back to Basic Agreement Talks

And so it stands to reason that inveterate madman George Miller has followed the most spectacular action movie of the 21st century not with a sequel that continues where “Mad Max: Fury Road” left off (though he hopes to make one of those someday), but rather with a prequel that paves the way to where it began. By the same token, it also stands to reason that Miller hasn’t tried to outdo the orgiastic mayhem that brought his Ozploitation franchise screaming into the 21st century all shiny and chrome — the guy might be insane, but he isn’t stupid. 

Nor is he willing to settle for diminishing returns. Rather than reaching for — and failing to clear — the impossibly high bar that he set for himself, Miller has chosen to do something even crazier and more rewarding: He’s created a symphonic, five-part, decades-spanning revenge saga so immense and self-possessed that it refuses to be seen as the mere extension of another movie, even though it manages to deepen the impact of “Fury Road” at every turn.

Does “Furiosa” deliver the kind of system shock that made its predecessor feel like such a violent rebuke to superhero-era Hollywood? Absolutely not — though its two bonafide setpieces both eclipse the most electric moments of “Fury Road,” while also iterating on them in fantastic new ways (the much-hyped “Stowaway to Nowhere” sequence is an out-of-body experience). But Miller’s decision to shift gears ultimately proves to be his prequel’s greatest strength, even for those of us who might wish that it could end with another 30-car pile-up instead of a proverbial fender-bender. 

Avoiding the same traps that have made too many recent franchise offshoots feel like just less of the same (in part because it was fully written before a frame of “Fury Road” had ever been shot), “Furiosa” doesn’t try to reverse-engineer one of the most propulsive cinematic experiences ever conceived so much as it scours the Wasteland for the emotion that will be required to fuel it. Whereas “Fury Road” was driven by the search for hope, “Furiosa” is a glorious film about why you need it in the first place.

It starts with a simple prompt: “As the world falls around us, how must we brave its cruelties?” Before “Furiosa” is finished with the first of its five distinct chapters, it will begin to offer two competing answers to that question. One is buried within young Furiosa (Alyla Browne, her performance so fierce and hyper-capable you might forget her role is due to be recast an hour later). Kidnapped from her idyllic home as a human map that her captors intend to sell to the nearest warlord (provided they can outrace the girl’s rifle-packing mother across the desert in a muted day-for-night chase that would be the coolest sequence in almost any other movie), Furiosa is instructed never to reveal the location of the Green Place from whence she came. Instead, she’s given a seed of her own to plant somewhere else, though she won’t understand the full implications of that gesture until halfway through the next film, when she realizes the difference between a home and a memory. 

Ruthless but theatrical, Dementus is only scary because you know he’ll take anything and everything he can in order to avoid thinking about what he’s lost. It would have been easy for Miller and his co-writer Nico Lathouris to imagine the main antagonist of this prequel as a mere sub-boss for “Fury Road” baddie Immortan Joe, but “Furiosa” tacks in the opposite direction by making Dementus the most loquacious character in the history of this franchise; by stressing his wayward humanity in a wasteland of inbred power-mongers (the ratty stuffed animal he keeps pinned on the back of his flowing white cape is a dead giveaway). Less motivated to rule than he is to build, Dementus shares Furiosa’s impulse for creation, the only difference being his foolish belief that anything useful might grow out of a world seeded with hate. 

Furiosa has other ideas. She disguises herself as a mute War Boy the first opportunity she gets, and then bides her time for the better part of a decade until she transforms into Anya Taylor-Joy and the chance avails itself to stow away in a War Rig that might lead her away from the Citadel. The driver of that hulking metal beast is a road warrior by the name of Praetorian Jack (“The Souvenir” breakout Tom Burke, one-upping Mel Gibson with just a knowing stare and a thick smudge of black paint across his forehead), and Furiosa senses that he’s capable of enough kindness to help steer her in the right direction. 

This set-up offers plenty of opportunity for the kind of fill-in-the-blank fan service that has made prequels so insufferable, but Miller doesn’t belabor the meet-cute between Furiosa and her twin-action “boom stick,” and even the inevitable reveal of how she loses her left arm is handled with refreshing casualness. To call undue attention to such details in the middle of a life-or-death sprint across the sand dunes would disrupt the rhythm of a film that unfolds with the precision of a symphony (I was often reminded of Park Chan-wook in that regard, especially as “Furiosa” curdles into a maximalist revenge saga), its violence so inextricable from its drama that even its moments of rest tend to vibrate across the screen with the shudder of a 1,000 engines being revved at once.

The virtuosity of Miller’s approach is so arresting that you might not even notice how seldom Furiosa actually speaks; like Charlize Theron before — or after? — her, Taylor-Joy conveys so much strength and desperation through the whites of her eyes alone that words would only cheapen the unparalleled purity of her purpose. That nascent intensity so perfectly matches the established template for the character that Taylor-Joy’s credible resemblance to Theron is just icing on the cake, and the former actress deserves kudos all her own for how willfully she kindles the flame that ignites the latter’s performance. In her hands, Furiosa is reborn as the rare film character who’s become iconic twice over in two distinct (but inseparable) forms, and future generations will awe at the fact that “Fury Road” came first. 

At certain junctures, the expansiveness of “Furiosa” can seem to its detriment, as Miller occasionally speeds over massive plot developments as if they were minor potholes; the life-changing apprenticeship that Praetorian Jack offers Furiosa is resolved in the span of a single fade, while the much-anticipated showdown between Dementus and Immortan Joe is yadda yadda yadda-ed off-screen with the help of some quick narration. Most egregious of all is how the time gaps make it hard to track Dementus and Immortan Joe’s respective relationships to Furiosa, such as they are.

For the most part, however, that such omissions might be misconstrued for oversights is a testament to the richness of this franchise’s lore, just as Miller’s refusal to distract from its heroine’s single-minded focus is ultimately to the benefit of a movie that sees chaos as Furiosa’s greatest chance to look for home, and not — as Dementus might conceive of it — as a home unto itself. 

Her quest to avenge her mother’s death is what drives this story, but that’s not what makes it worth telling. “Furiosa” derives its inestimable horsepower from how it forces its heroine to watch Dementus’ motorcycle horde ride in circles for 15 years, killing themselves and countless others in a futile bid to control a part of an irradiated Wasteland we already know they won’t be able to keep. Each new indignity brings her closer to accepting that going nowhere with hope is better than going anywhere without it.

How do we brave the world’s cruelties? By refusing to become them ourselves. Such an internally combusting prequel might seem like a strange lead-in to a movie that spit fire in every direction, but don’t you worry: George Miller still has what it takes to make it epic. 

Warner Bros. will release “Furiosa: A Mad Max Saga” in theaters on Friday, May 24.
