Solving problems in Smart Technology

Consider the hottest topic in industry today – Smart Manufacturing, or Industry 4.0, sometimes called the Industrial Internet of Things (IIOT). Industry 4.0 is just one facet of the global push towards Smart Cities, Smart Homes, and Smart Agriculture.

All these concepts center on wireless connectivity between machines using cellular networks. So, for Smart Homes, this means your utilities, fridge, lights, security, HVAC, and other systems would be connected through an app on your smartphone. From there you can track and control these systems to keep your home safe and comfortable, while reducing water and energy use.

For Industry 4.0, companies are connecting the machines used in their manufacturing and power generation plants at different locations around the world. On top of that, they are creating “digital twins” of each machine, which are 3D animated computer models of the machines.

The idea is to collect real-time data from each machine and then use that data, along with artificial intelligence (AI), machine vision, and even virtual reality simulations, to:

• Design new products
• Predict when a machine will need maintenance BEFORE something goes wrong
• Optimize the output of the machines and harmonize them to work together

Solving problems in Robotics

Another major topic in industry is  robotics and automation . Automation means that machines are programmed to perform tasks without human help. Some robots are standalone, “service” robots, like the Roomba. Others, like robotic arms in factories and warehouses, pick and place items to be processed.

The more human-friendly “collaborative” robots can improve human capacity and are safe to work around. Put together, these technologies allow some manufacturing plants to run “lights out,” without any human input for days.

Robots are boosting agriculture, both in planting and harvesting fields and in packaging food. With Smart Agriculture technology, farmers collect data in their fields with mobile apps applying artificial intelligence (AI) software to reduce fertilizer needs and optimize water use.

When students learn within the context of authentic, problem-based STEM design, they can more clearly see the genuine impact of their learning. That kind of authenticity builds engagement, taking students from groans of “When will I ever use this?” to a genuine connection between skills and application.

Using STEM to promote critical thinking and innovation

“Educational outcomes in traditional settings focus on how many answers a student knows. We want students to learn how to develop a critical stance with their work: inquiring, editing, thinking flexibly, and learning from another person’s perspective,” says Arthur L. Costa in his book Learning and Leading with Habits of Mind . “The critical attribute of intelligent human beings is not only having information but also knowing how to act on it.”

Invention and problem-solving aren’t just for laboratory thinkers hunkered down away from the classroom. Students from elementary to high school can wonder, design, and invent a real product that solves real problems. “ Problem-solving involves finding answers to questions and solutions for undesired effects. STEM lessons revolve around the engineering design process (EDP) — an organized, open-ended approach to investigation that promotes creativity, invention, and prototype design, along with testing and analysis,” says Ann Jolly in her book STEM by Design . “These iterative steps will involve your students in asking critical questions about the problem, and guide them through creating and testing actual prototypes to solve that problem.”

Explore the best science fair projects for elementary kids

While classic projects like making a cyclone in a bottle or stacking liquids to teach density can make a lasting impact on kids, these projects offer some unique ways of getting elementary schoolers to engage with science.

1. LEGO Zipline

Kids love LEGO and this project only requires a few blocks and some lengths of string. Projects can teach kids about Physics concepts like gravity, tension, friction, as well as Math ideas like slope, angle, and weight. Set a large slope to make the zip line fast, and add slack to the line to slow it down. You could even arrange this project as a race.

2. Slow Ball Race

Another race idea involves building a tower of ramps to allow a ball to roll down. To give your students a unique challenge, instead of making the ball rush to the bottom, you can have them compete to see who makes the ball reach the bottom slowest. All you need are some building materials (paper, cardboard, or plastic) and a ball, ideally something small and smooth like a ping pong ball.

3. Hot/Cold Water Density Project

For this project, students will only need some clear containers of the same size, hot and cold water and food coloring. Students will study the characteristics of water and how its density changes based on temperature. By adding one color to the cold and another to the hot, students then will stack the openings on top of each other, and if done correctly, the different temperature liquids will remain separate. Pretty cool.

4. Soil Erosion in a Bottle

This simple project requires garden soil, some plants with roots in the soil, and three clear soda bottles. After cutting out the side of each bottle, they will then be filled with different materials. In one bottle there will be simple soil, in another the soil could be mixed with rocks, branches, and other large chunks. In the final bottle, students will plant some flowers, whose roots will prevent the soil from eroding. As water is poured through the others, students will witness how plants help preserve and retain our most precious resource: the Earth.

5. Water Filtration

In another climate science project, students will use a variety of materials to experiment with water filtration. By pouring dirty water through a mix of sand, charcoal, rocks, and debris, students can collect the filtered water and demonstrate how clean it is by passing through the filter. This could be a supplement to conversations about the water cycle.

See the best science fair project ideas for middle school kids

Middle schoolers will be able to do more independent projects, and they should have a higher bar for formulating a hypothesis and repeatedly testing it. By analyzing the data in a group, students can improve their verbal reasoning skills in a team.

6. Seed Sprouting Experiment

With some seeds and some containers filled with various growing media (sand, soil, mulch, compost, etc.), students can test which material is ideal for sprouting seeds. Students can also study ideas of sustainability, food security, and climate change/soil erosion as part of their project.

7. Newton’s Balloon Car

“For every action there is an equal and opposite reaction,” is one of the most famous quotes in science and engineering, and one of Sir Isaac Newton’s most famous Laws of the physical world. Middle school students can experience this law first hand by building a toy car that propels itself with the expelled air of an inflated balloon. Kids love this experiment because it can be presented as a race.

One of the best things about quick STEM activities is that there are no right or wrong answers.

In a true STEM experiment, children learn to think of solutions to problems on their own, with no particular planned outcome, just like in the real world.

STEM activities are one of the best ways to prepare children for problem solving and learning in the real world, and they give kids a taste of what sort of decision processes adults go through every day.

With the openness of STEM activities guiding children, there is no fear of failure and children who typically look for the “right” answer are encouraged to explore a topic, rather than just memorizing an answer.

Kids who regularly engage in quick STEM activities are better able to solve problems, think outside the box, go through a logical process to come up with an answer, and can tell you why they chose a certain solution clearly.

What Kids Learn Doing Quick STEM Activities

Quick STEM activities help illustrate the concepts of science, technology, engineering, and math in a fast, easy-to-see way that is ideal for quick science and STEM lessons, such as for early elementary science class, kindergarten lessons, STEM and science centers, preschool, STEM summer camp, and more!

The quick demonstrations work well when time crunches are an issue, and for many of these activities, kids can do them alone, making them perfect for self-guided play and exploration.

 45+ Engineering Science Fair Projects (and advice!)

Before I started Innovative Arts class, I was a science teacher. The science and engineering fairs were ultra engaging and everyone learned so much! I hope you are excited by the possibilities that lie ahead. A lot of the resources I have created can help you have a great experience.

What is so great about engineering science fair projects?

Engineering science fair projects can be a great way for students to develop problem solving, critical thinking, and research skills in a fun and engaging way. They are challenging! We do our best learning and growing when we are challenged. If you’re looking for some ideas for engineering science fair projects that your child can do at home or in school, here are my best ideas and resources. 

Do some popsicle stick engineering!

This one is my favorite. With a little patience and way to drill a hole in a popsicle stick, you can make a very cool project! Check out my entire page of movements and example videos .

Build Your Own Wind-Powered Car 

For this project, students create a wind-powered car out of everyday materials like cardboard or Styrofoam. It’s great for kids who are interested in renewable energy sources because it gives them hands-on experience building something that runs on wind power instead of electricity or gasoline. Plus, it helps them learn about aerodynamics and basic physics concepts like drag force and momentum—all while having fun!  

If you bring a fan to the fair, you could have a pretty cool demonstration set up for people to play with! Look at possible car projects.

Designing the Strongest Bridge 

In this project, students must design the most durable bridge out of everyday materials such as toothpicks, popsicle sticks, straws, string, etc. It teaches them problem solving skills as they figure out which materials will make their bridge strong enough to withstand certain levels of pressure without breaking down. Additionally, it helps them understand basic physics principles such as tension and compression forces.  

To take it a little further, you could test different designs and display the broken bridges with how much weight it took to break them. Possible bridge projects

Designing Windmills

 Windmills are becoming more popular these days due to renewable energy initiatives around the world. Designing windmills is another great engineering project because it involves researching different types of wind turbines and their associated components like blades and hubs. After researching wind turbine designs students can then go ahead with designing their own prototype using cardboard or other available materials. 

Bring a fan and let your windmill turn while the fair is being judged! Start looking for windmill projects here .

 Creating an Effective Water Filter System 

This project requires students to use everyday items such as coffee filters and gravel to construct an effective water filter system that can clean dirty water into drinkable water. It’s ideal for children who want to learn how filtration systems work since it gives them first-hand experience designing one from start to finish! Plus, it provides important lessons about water purification methods too!  

To do this, research some simple water filter setups and choose an easy option. Make sure you demonstrate it at the fair! I would start here .

Creating Robots

 Another great engineering project is creating robots. Robotics is becoming increasingly important in our society and more companies are investing in robotics research and development every day. To create a robot, students need to understand the components needed such as motors, microcontrollers, sensors, etc., as well as the coding language used to program them. Once these basics are understood students can start designing their own robot prototype! 

There are a lot of kits available for this. I recommend using a robot that can be programmed using Scratch because you can learn it so quickly! See my tutorials below.

Other project ideas available!

I’ve spent years figuring out what works in a middle school classroom using cheap materials. Here are just a few projects from class!

 Engineering science fair projects are a great way for students to apply their knowledge in STEM topics in real life situations while getting creative with their designs at the same time! Whether your child is interested in robotics or renewable energy sources, there’s bound to be an engineering science fair project that fits his/her interests perfectly!

I am creating this site to advance student creativity and help students to take ownership of their learning . The resources on this site are intentionally open-ended and a part of my Innovative Arts curriculum .

50 Simple STEM Activities using 15 Materials

I started doing simple STEM activities with my children at home, and students at school, a few years ago. They all loved it! They were always excited when I brought in materials and gave them a chance to create, problem solve and use their imagination. Because of the learning and engagement I saw every time we did one of this projects, STEM activities have become a regular part of my teaching program.

One of the great things about STEM activities is that they don’t have to be expensive. As a teacher I wanted to find a collection of STEM activities and challenges that didn’t require expensive materials or a lot of prep.

I created this collection of 50 Simple STEM Activities using only 15 materials. Most of the materials are supplies you likely already have on hand, such as paper, elastics and scissors.

STEM activities are a great way to develop Science, Technology, Engineering and Math skills. The more of these skills mixed into the activity, the better.

The collection of 50 STEM activities featured below are all hands-on building challenges. They each use, one or several of the 15 materials needed to do all of the challenges.

If you teach a STEM program, or simply want to bring more STEM to your child’s learning, this program is the perfect place to start. Print the activity cards, fill a bin with the 15 materials and you’re ready to go!

For more STEM activities, check out 10 Exciting STEM Activities with 10 Materials and the popular collection of 45+ STEM Challenge Ideas for Kids .

Simple STEM Activities Materials

There are 15 materials you will need in order to do the STEM challenges. The more of each material you can collect, the better. All of the 50 STEM activities in this program use some combination of the materials below. It may look like a lot of supplies, but keep in mind that it is for 50 different activities! You will need:

• Wooden blocks
• Construction paper
• Clothes pins
• Plastic cups
• Plastic building blocks
• Ping pong ball
• Large craft sticks (tongue depressors)
• Paper rolls
• Aluminum foil

Once materials are used for a STEM challenge, hang onto any left over supplies and any other supplies that can be reused for your next STEM challenge. Many of the challenges allow the materials to be recycled and used again and again.

I’ve included an example below of a STEM bin I created in the past full of materials that I pulled from for each STEM challenge.

Once you have all of your materials collected, print the activity cards for the challenges.

Benefits of Simple STEM Activities

STEM activities are a great, and fun way to encourage essential skills. These challenges promote critical thinking, creativity, team work, and problem solving. Children learn that the process is as important, if not more important than the final result.

A key part of STEM challenges is trial and error. Encourage children to create and test their solution. If it doesn’t work, have them think about what does work, and what doesn’t and recreate based on what they have learned.

If there is an activity in this collection that you think is going to be too challenging for your group of children, you can always alter the activity, or add more supplies, to make the activity easier. However, avoid helping children as soon as they run into problem. Part of the learning comes when children get stuck. Give them the chance to learn from their mistakes.

STEM Activity Printables

There are 50 activity cards included in the product for the STEM challenges. They are included in the resource in different formats. Print the format that works best for you.

You can print the full page cards, half page or smaller (4 per page) activity cards. Each of the sets are included in black and white and color.

Beyond the activity cards, the resource also includes instructions on how to use the cards, a material list to help keep you organized as you collect materials, and a marking rubric if you are using the resource in a class setting.

Included in the printables, there is also information about STEM education, a student planning sheet, certificates for children upon completing STEM challenge(s) and a list of all of the activities.

If you are just starting your STEM program, these are great sheets and information to make setting up your program easy.

The title of the activity, the challenge as well as the materials needed are all listed on the activity card. A picture of the supplies needed is included to help children know what materials they can use for the challenge.

Preparing Your STEM Activities

Whether you use the activities to keep kids busy on rainy days or plan a weekly STEM challenge virtually all year round, this resource is easy to set up and, with the exception of collecting materials, there is no extra prep work involved.

There are lots of different ways you can set up your STEM program. You can print the cover page with the activity cards to create individual packages for children to work through at their own pace, as one option.

Since I have been doing STEM activities in my classroom for several years, I have found that they make great centers!

Grab a collection of clear bins, print an activity card and attach the card to the top. Inside the bin, include the materials children need for the challenge.

For older children, you can print the smaller activity cards and attach them all with a ring. I laminated my set so that I can use them for many years. Children can choose an activity, and grab the supplies needed and begin creating.

Another way to use the activity cards is to print them and put them in a bag along with the supplies needed for the challenge. These make great kits, or gifts, to give to children to create with at home.

Get your STEM program ready and prepared quickly and easily with the 50 simple STEM activities shown above.

• Problem Solving in STEM

Solving problems is a key component of many science, math, and engineering classes.  If a goal of a class is for students to emerge with the ability to solve new kinds of problems or to use new problem-solving techniques, then students need numerous opportunities to develop the skills necessary to approach and answer different types of problems.  Problem solving during section or class allows students to develop their confidence in these skills under your guidance, better preparing them to succeed on their homework and exams. This page offers advice about strategies for facilitating problem solving during class.

How do I decide which problems to cover in section or class?

In-class problem solving should reinforce the major concepts from the class and provide the opportunity for theoretical concepts to become more concrete. If students have a problem set for homework, then in-class problem solving should prepare students for the types of problems that they will see on their homework. You may wish to include some simpler problems both in the interest of time and to help students gain confidence, but it is ideal if the complexity of at least some of the in-class problems mirrors the level of difficulty of the homework. You may also want to ask your students ahead of time which skills or concepts they find confusing, and include some problems that are directly targeted to their concerns.

You have given your students a problem to solve in class. What are some strategies to work through it?

• Try to give your students a chance to grapple with the problems as much as possible.  Offering them the chance to do the problem themselves allows them to learn from their mistakes in the presence of your expertise as their teacher. (If time is limited, they may not be able to get all the way through multi-step problems, in which case it can help to prioritize giving them a chance to tackle the most challenging steps.)
• When you do want to teach by solving the problem yourself at the board, talk through the logic of how you choose to apply certain approaches to solve certain problems.  This way you can externalize the type of thinking you hope your students internalize when they solve similar problems themselves.
• Start by setting up the problem on the board (e.g you might write down key variables and equations; draw a figure illustrating the question).  Ask students to start solving the problem, either independently or in small groups.  As they are working on the problem, walk around to hear what they are saying and see what they are writing down. If several students seem stuck, it might be a good to collect the whole class again to clarify any confusion.  After students have made progress, bring the everyone back together and have students guide you as to what to write on the board.
• It can help to first ask students to work on the problem by themselves for a minute, and then get into small groups to work on the problem collaboratively.
• If you have ample board space, have students work in small groups at the board while solving the problem.  That way you can monitor their progress by standing back and watching what they put up on the board.
• If you have several problems you would like to have the students practice, but not enough time for everyone to do all of them, you can assign different groups of students to work on different – but related - problems.

When do you want students to work in groups to solve problems?

• Don’t ask students to work in groups for straightforward problems that most students could solve independently in a short amount of time.
• Do have students work in groups for thought-provoking problems, where students will benefit from meaningful collaboration.
• Even in cases where you plan to have students work in groups, it can be useful to give students some time to work on their own before collaborating with others.  This ensures that every student engages with the problem and is ready to contribute to a discussion.

What are some benefits of having students work in groups?

• Students bring different strengths, different knowledge, and different ideas for how to solve a problem; collaboration can help students work through problems that are more challenging than they might be able to tackle on their own.
• In working in a group, students might consider multiple ways to approach a problem, thus enriching their repertoire of strategies.
• Students who think they understand the material will gain a deeper understanding by explaining concepts to their peers.

What are some strategies for helping students to form groups?  

• Instruct students to work with the person (or people) sitting next to them.
• Count off.  (e.g. 1, 2, 3, 4; all the 1’s find each other and form a group, etc)
• Hand out playing cards; students need to find the person with the same number card. (There are many variants to this.  For example, you can print pictures of images that go together [rain and umbrella]; each person gets a card and needs to find their partner[s].)
• Based on what you know about the students, assign groups in advance. List the groups on the board.
• Note: Always have students take the time to introduce themselves to each other in a new group.

What should you do while your students are working on problems?

• Walk around and talk to students. Observing their work gives you a sense of what people understand and what they are struggling with. Answer students’ questions, and ask them questions that lead in a productive direction if they are stuck.
• If you discover that many people have the same question—or that someone has a misunderstanding that others might have—you might stop everyone and discuss a key idea with the entire class.

After students work on a problem during class, what are strategies to have them share their answers and their thinking?

• Ask for volunteers to share answers. Depending on the nature of the problem, student might provide answers verbally or by writing on the board. As a variant, for questions where a variety of answers are relevant, ask for at least three volunteers before anyone shares their ideas.
• Use online polling software for students to respond to a multiple-choice question anonymously.
• If students are working in groups, assign reporters ahead of time. For example, the person with the next birthday could be responsible for sharing their group’s work with the class.
• Cold call. To reduce student anxiety about cold calling, it can help to identify students who seem to have the correct answer as you were walking around the class and checking in on their progress solving the assigned problem. You may even want to warn the student ahead of time: "This is a great answer! Do you mind if I call on you when we come back together as a class?"
• Have students write an answer on a notecard that they turn in to you.  If your goal is to understand whether students in general solved a problem correctly, the notecards could be submitted anonymously; if you wish to assess individual students’ work, you would want to ask students to put their names on their notecard.  
• Use a jigsaw strategy, where you rearrange groups such that each new group is comprised of people who came from different initial groups and had solved different problems.  Students now are responsible for teaching the other students in their new group how to solve their problem.
• Have a representative from each group explain their problem to the class.
• Have a representative from each group draw or write the answer on the board.

What happens if a student gives a wrong answer?

• Ask for their reasoning so that you can understand where they went wrong.
• Ask if anyone else has other ideas. You can also ask this sometimes when an answer is right.
• Cultivate an environment where it’s okay to be wrong. Emphasize that you are all learning together, and that you learn through making mistakes.
• Do make sure that you clarify what the correct answer is before moving on.
• Once the correct answer is given, go through some answer-checking techniques that can distinguish between correct and incorrect answers. This can help prepare students to verify their future work.

How can you make your classroom inclusive?

• The goal is that everyone is thinking, talking, and sharing their ideas, and that everyone feels valued and respected. Use a variety of teaching strategies (independent work and group work; allow students to talk to each other before they talk to the class). Create an environment where it is normal to struggle and make mistakes.
• See Kimberly Tanner’s article on strategies to promoste student engagement and cultivate classroom equity. 

A few final notes…

• Make sure that you have worked all of the problems and also thought about alternative approaches to solving them.
• Board work matters. You should have a plan beforehand of what you will write on the board, where, when, what needs to be added, and what can be erased when. If students are going to write their answers on the board, you need to also have a plan for making sure that everyone gets to the correct answer. Students will copy what is on the board and use it as their notes for later study, so correct and logical information must be written there.

What Is an AHK File?

Keeping yourself safe in college: everything you need to know, myths about online high schools: everything you need to know, reasons you should study geography: everything you need to know, the vtoman jump 1800 portable power station: the best of the best, key roles of a school superintendent: everything you need to know, is earning a degree online worthwhile and beneficial, why learners cheat: everything you need to know, top issues in education: everything you need to know, duties of a school principal: everything you need to know, 14 project-based learning activities for the science classroom.

One of the most popular methods of facilitating deep learning in K-12 schools in problem-based learning. It starts, as the name suggests, with a problem. In this model, students are presented with an open-ended problem. Students must search through a variety of resources, called trigger material, to help them understand the problem from all angles. What would project-based learning look like in a subject like science? That’s what I plan to explore in this piece. Below you will find a list of 14 project-based learning activities for the K-12 science classroom.

• Student Farm. Students will learn lessons about science, social studies, math, and economics through planting their organic farm. They can begin by researching the crops they want, figure out what kind of care is needed, and then use a budget to determine what materials they must purchase. They can even sell food from their farm to contribute to a cause or fundraiser.
• Bridge Building. Students begin by studying the engineering of bridge building, comparing the construction of famous bridges such as the Golden Gate Bridge or Tower Bridge in London. Then they work in teams to construct bridges out of Popsicle sticks. The challenge is to get their bridge to hold five pounds (for younger students) or twenty pounds (for more advanced students).
• Shrinking Potato Chip Bags in the Microwave. Students can learn about polymers through hands-on activities using some of their favorite products, like shoes and sporting equipment. As a culminating activity, they can put a wrapper from their favorite chips or candy bar into the microwave for five seconds to learn about how polymers return to their natural state when exposed to the heat.
• Design an App. Students love using the newest apps and games, so take it to the next level by having them design their own! With Apple developer tools, kids can learn how to create an app or online game. They can learn about technology and problem-solving skills while engaged in what they love.
• Gummy Bear: Shrink or Grow? For a project-based lesson on osmosis and solubility, you will just need gummi bears and different liquids and solutions (water, salt water, vinegar, etc.). Children will place a gummi bear in each solution overnight and then measure the results.
• The Old Egg in a Bottle Trick . This old trick is an impressive PBL activity for kids to learn about the correlation between temperature and pressure,. Using just eggs, a wide mouth glass bottle, matches, and strips of paper, children will be able to make an egg “magically” fit through the bottle’s opening.
• Cabbage Acid-Base Indicator . Children will love this hands-on approach to learning how to identify an acid or a base just using purple cabbage and seeing colors change.
• Carnation Color Wonders . An uncomplicated way to teach the importance of the various parts of the flower, the carnation color experiment shows kids how stems provide nourishment to the whole plant.
• Polymers & Pampers . If your middle school scientist has a younger sibling at home in diapers, this is a great PBL activity to teach how polymers are essential for products like diapers.
• Make a Battery Using… Anytime a kid can turn produce into a battery, it is fun! So, why not compare a lemon battery to a potato battery to see which one works better?
• Helmet Drop Test . The helmet drop test is a practical PBL project to teach kids the importance of safety helmets. Simply gather different types of helmets and a several melons. Strap the helmets to the melons and drop each from the same height and measure the results.
• How Much Sugar is in that Soda? . Health-conscious parents will love this PBL activity because it teaches kids how much sugar is in their soft drinks. If you have soft drinks, sugar, and measuring cups, you can do this experiment in your kitchen.
• Ways to Clean a Penny . To teach children how acid reacts with salt works to remove the dullness of pennies, kids can do a simple PBL activity using salt and vinegar. They can also test other acids to compare results.
• Oranges: Float or Sink? . To teach kids about density, all you need are oranges and a bowl of water. You can add to this experiment by testing other fruits with peels.

65+ Real-World Project-Based Learning Ideas for All Ages and Interests

Find and implement solutions to real-world problems.

Project-based learning is a hot topic in many schools these days, as educators work to make learning more meaningful for students. As students conduct hands-on projects addressing real-world issues, they dig deeper and make personal connections to the knowledge and skills they’re gaining. But not just any project fits into this concept. Learn more about strong project-based learning ideas, and find examples for any age or passion.

What is project-based learning?

Project-based learning (PBL) uses real-world projects and student-directed activities to build knowledge and skills.

Abstract: In this study, we investigated the effects of self-reflection in large language models (LLMs) on problem-solving performance. We instructed nine popular LLMs to answer a series of multiple-choice questions to provide a performance baseline. For each incorrectly answered question, we instructed eight types of self-reflecting LLM agents to reflect on their mistakes and provide themselves with guidance to improve problem-solving. Then, using this guidance, each self-reflecting agent attempted to re-answer the same questions. Our results indicate that LLM agents are able to significantly improve their problem-solving performance through self-reflection ($p < 0.001$). In addition, we compared the various types of self-reflection to determine their individual contribution to performance. All code and data are available on GitHub at this https URL
