The Learning Myth: Why I'll Never Tell My Son He's Smart

$

By: Salman Khan

Update: This Op-ed was part of a Khan Academy initiative to change how people think about learning. Since then we have launched LearnStorm, a free Common Core math challenge for 3rd-12th graders in the Bay Area to give parents, teachers and students a hand-on way to practice better learning mindsets. If you’re a parent, teacher or student in the Bay Area you can sign up for LearnStorm here.


My 5-year-­old son has just started reading. Every night, we lie on his bed and he reads a short book to me. Inevitably, he’ll hit a word that he has trouble with: last night the word was “gratefully.” He eventually got it after a fairly painful minute. He then said, “Dad, aren’t you glad how I struggled with that word? I think I could feel my brain growing.” I smiled: my son was now verbalizing the tell­-tale signs of a “growth­ mindset.” But this wasn’t by accident. Recently, I put into practice research I had been reading about for the past few years: I decided to praise my son not when he succeeded at things he was already good at, but when he persevered with things that he found difficult. I stressed to him that by struggling, your brain grows. Between the deep body of research on the field of learning mindsets and this personal experience with my son, I am more convinced than ever that mindsets toward learning could matter more than anything else we teach.

Researchers have known for some time that the brain is like a muscle; that the more you use it, the more it grows. They’ve found that neural connections form and deepen most when we make mistakes doing difficult tasks rather than repeatedly having success with easy ones.

What this means is that our intelligence is not fixed, and the best way that we can grow our intelligence is to embrace tasks where we might struggle and fail.

However, not everyone realizes this. Dr. Carol Dweck of Stanford University has been studying people’s mindsets towards learning for decades. She has found that most people adhere to one of two mindsets: fixed or growth. Fixed mindsets mistakenly believe that people are either smart or not, that intelligence is fixed by genes. People with growth mindsets correctly believe that capability and intelligence can be grown through effort, struggle and failure. Dweck found that those with a fixed mindset tended to focus their effort on tasks where they had a high likelihood of success and avoided tasks where they may have had to struggle, which limited their learning. People with a growth mindset, however, embraced challenges, and understood that tenacity and effort could change their learning outcomes. As you can imagine, this correlated with the latter group more actively pushing themselves and growing intellectually.

The good news is that mindsets can be taught; they’re malleable. What’s really fascinating is that Dweck and others have developed techniques that they call “growth mindset interventions,” which have shown that even small changes in communication or seemingly innocuous comments can have fairly long­-lasting implications for a person’s mindset. For instance, praising someone’s process (“I really like how you struggled with that problem”) versus praising an innate trait or talent (“You’re so clever!”) is one way to reinforce a growth ­mindset with someone. Process­ praise acknowledges the effort; talent­ praise reinforces the notion that one only succeeds (or doesn’t) based on a fixed trait. And we’ve seen this on Khan Academy as well: students are spending more time learning on Khan Academy after being exposed to messages that praise their tenacity and grit and that underscore that the brain is like a muscle.

The Internet is a dream for someone with a growth mindset. Between Khan Academy, MOOCs, and others, there is unprecedented access to endless content to help you grow your mind. However, society isn’t going to fully take advantage of this without growth mindsets being more prevalent. So what if we actively tried to change that? What if we began using whatever means are at our disposal to start performing growth mindset interventions on everyone we cared about? This is much bigger than Khan Academy or algebra — it applies to how you communicate with your children, how you manage your team at work, how you learn a new language or instrument. If society as a whole begins to embrace the struggle of learning, there is no end to what that could mean for global human potential.

And now here’s a surprise for you. By reading this article itself, you’ve just undergone the first half of a growth­-mindset intervention. The research shows that just being exposed to the research itself (­­for example, knowing that the brain grows most by getting questions wrong, not right­­) can begin to change a person’s mindset. The second half of the intervention is for you to communicate the research with others. We’ve made a video (above) that celebrates the struggle of learning that will help you do this. After all, when my son, or for that matter, anyone else asks me about learning, I only want them to know one thing. As long as they embrace struggle and mistakes, they can learn anything.

New course: Learn to make your web pages interactive with JavaScript

$

On Khan Academy, our two most popular programming courses are Intro to JavaScript, where you learn the fundamentals of JavaScript with the ProcessingJS library, and Intro to HTML/CSS, where you learn to create, style, and lay out a web page. But that’s like having strawberries and chocolate in front of you, and not dunking a strawberry in the chocolate.

Why? Well, JavaScript was originally invented in order to bring HTML/CSS web pages to life, to make them interactive with events and animation. The language has become very popular since its invention and is now used outside of browsers, but, still today, it is the only language that browsers natively understand and it is used by every interactive web page on the internet.

That’s why we’ve put together a course on making web pages interactive— combining your knowledge of HTML/CSS with your knowledge of JavaScript so that you can programmatically access parts of your page and modify them in response to all sorts of user events. With that knowledge, you can make slideshows, games, galleries, apps — virtually anything you’ve seen on the web.

Khan Academy helps students prepare for medical school admission test

There were many memorable moments on my road to becoming a doctor, but a few stand out.

1. Biking to the hospital in the snow, day after day after day (it was in Boston), during residency. Wet scrubs are no fun.

2. Talking to a teenage girl who was embarrassed about having to find a prom dress that would cover the large psoriasis plaques on her elbows

3. High-fiving and hugging a patient-turned-friend moments after finding out his leukemia was in remission!

4. Helping to give a baby its first breath…

5. Studying for the MCAT® exam (Medical College Admission Test)

Are you surprised that last one made the list? Don’t be. I studied for the MCAT for weeks and weeks, and walked out feeling drained. It was a grueling experience and I was a basket case, running around trying to balance my class-load with finding reliable study materials and knocking out practice questions on weekends. For three long months, I ate, slept, studied, and stressed (in that order). But I realize that the work I put into preparing helped get me ready for medical school.

This April, the Association of American Medical Colleges (AAMC) is unveiling a new and improved MCAT exam. More than 80,000 individuals will take this new test on their road to medical school each year. And with the help of the AAMC and a grant from the Robert Wood Johnson Foundation, Khan Academy has built resources to help students prepare for the exam.

For the past two years, we’ve worked with a fantastic team of educators to create more than 900 videos and 2,000 questions spanning all of the foundational concepts tested on the new exam. These include biochemistry, biology, physiology, physics, chemistry, and - for the first time ever - the social sciences, specifically psychology and sociology.  

It’s amazing to think that within four years, students taking the new MCAT are going to be physicians in every single clinic, hospital, and operating theater across the United States and Canada. They’ll be caring for you or someone you love.

We know that aspiring medical students want to learn, and we want to be a small part of their journey. Good luck to everyone taking the new MCAT exam - we hope you find our new study tools helpful!

Students celebrate at the LearnStorm finals

Sherry*, a 5th grade student, didn’t want to come to Google. For months she’d been working hard on LearnStorm, the Khan Academy math challenge, and had earned a top spot on the leaderboards. For weeks our team had been working with Google to build the most epic final award celebration we could devise. We asked her teacher, Jen Ellison, what was up and the response was heartbreaking:

“I don’t ride in cars much.”

Ms. Ellison said Sherry’s response reminded her of the crippling effects of poverty. Sherry is ten years old. She doesn’t often leave her neighborhood. “Driving an hour away might as well be the moon.”

The thing is, this kind of self-limiting thinking is not only a problem for kids from underserved neighborhoods: most people are held back in some way by their mindset. Last year Edelman-Berland helped us do a poll that showed that the majority of people think their intelligence level is fixed. The research shows not only that this is inaccurate, but also that when students think this way, their test scores suffer, and they are less likely to take on the learning challenges that will set them up for future success.

We designed LearnStorm as a direct attack on these ways of thinking. We knew that to be truly impactful we would need to create a hands-on way to practice positive learning mindsets. Could we design a math challenge that taught a lot more than just math?

We launched LearnStorm in the Bay Area as a pilot. Based on what we’d learned from other math competitions, we aimed to reach at least one percent of students in grades 3-12, which is about 13,000. Three months later, over 73,000 students from about 1,600 Bay Area schools have participated in LearnStorm. They’ve earned points and prizes not only for mastering math skills but also for showing “hustle,” a metric we created to measure grit, perseverance, and growth. They competed over 200,000 hours of learning and 13.6 million standards-aligned math problems.

In addition, thanks to the generosity of Google.org, DonorsChoose.org, and Comcast’s Internet Essentials, 34 underserved schools unlocked new devices for their classrooms and free home internet service for eligible families, increasing student access to online learning tools like Khan Academy.

On Saturday, we invited the LearnStorm students who mastered the most math and showed the most hustle to a finals celebration on the Google campus. These students competed in individual and team challenges and earned educational prizes from organizations such as the Exploratorium, Ardusat, the Lawrence Hall of Science, the Tech Museum of Innovation, the California Academy of Sciences, NASA, NASCAR, and the San Francisco 49ers.

Thanks to the efforts of her teacher, Ms. Ellison, Sherry was there. Thanks to her grit, determination and growth in math, she earned a prize and was celebrated by 300 of her peers from across the Bay Area at the heart of Google. As Ms. Ellison put it:

“LearnStorm taught us about hope, endurance and grit… It taught us to encourage one another because everyone struggles. It taught us that you can learn anything. It taught us that we are capable of more than we can imagine…. Oh, and we learned some math, too.”

At Khan Academy we’ve been inspired by Sherry and all the participants, volunteers, teachers and parents who made this LearnStorm pilot such a success. We’re working with the same hustle, grit and determination to make LearnStorm bigger and better. So stay tuned for updates later this year!

Hi, I’m Cam from Khan Academy, and I challenge you to join me for a surge of summer learning!

I'm learning!

I can’t unicycle yet, but I’m learning. My other summer learning goals are focused around biology and economics.

No matter what you choose to learn on Khan Academy, you’ll be eligible to earn two special badges:

- Get the Summer Surge badge by earning at least 50,000 energy points this summer.

- Get the I Beat Cam badge by earning more points than I do this summer.

The challenge runs from the June 23rd through August 28th (official rules below). There’s no special signup to earn these badges; all you have to do is start learning now!

Not sure what you want to learn this summer? Here are three ideas:

1. Supercharge your math skills. For example, if you’re headed into Algebra I, jump into the Algebra I mission and get started on those mission foundations (pre-requisites) to make sure you start the school year strong!

2. Join Pamela in a Summer of Scripting! Sign up for reminders and weekly contests to help you learn JavaScript, one of the world’s most popular and important programming languages!

3. Explore a new topic you’ve always been curious about, such as economics, finance, art history, or health and medicine. Remember: You can learn anything!

I look forward to learning alongside you this summer. You can track my summer learning progress by watching my KA profile or by following me @icamlearn on Instagram or Twitter. Let me know what you’re learning using the hashtag #KASummerSurge.

Your fellow learner,

Official rules

All points earned anytime from the very start of the day (PDT) on June 23rd to 11:59pm PDT on August 28th will count towards these badges.

Badges (described above) will be awarded only after the contest has ended. I’ll give everyone their badges on August 31st.

Who is beating me so far?

I have earned a total of 0 points so far this summer (as of June 23rd), so I imagine lots of people are beating me right now. But, remember, badges are awarded at the end of the summer (after August 28th), and you’ll only get the “I Beat Cam” badge if you earn more points than I do over the course of the entire summer.

Check back here in coming weeks to see a list of usernames that are beating me.

College students share their experiences with Khan Academy

This spring, Stanford Consulting - a nonprofit, student-run organization - ran a survey to learn about the impact that Khan Academy has had on the educations of current college students. These students were asked whether they “found Khan Academy meaningful to their education” and whether they were the first in their family to go to college. The results are in, and today we’re excited to share some of the key findings.

Of the students who responded to the survey…

- 65% of Stanford students found KA meaningful to their education (out of 504 surveyed)
- 57% of students in other top schools* found KA meaningful to their education (out of 159 surveyed)
- 64% of first-generation college students (the first in their family to go to college) at these schools found KA meaningful to their education (out of 164 surveyed)

*Surveyed schools include Harvard, Princeton, the University of Pennsylvania, UC Berkeley, Caltech, Notre Dame, MIT, Vanderbilt, and Yale.

We’re thrilled to see how many college students have benefited from Khan Academy and to hear their stories. One first-generation student from Stanford shared the following note with us:

For all the times I couldn’t turn to my parents for homework help, I had Khan Academy videos to help me. Khan Academy was the private tutor that my family could not afford. For all the times I wanted to learn for the sake of learning, I would pick from the hundreds of Khan Academy videos.

Every day, learners around the world visit Khan Academy to brush up their skills and explore new subjects. Maybe you’ve studied math on Khan Academy, and maybe you’ve wondered how artists, scientists, and engineers use math to build amazing things.

To help answer that question, Khan Academy, with support from Disney, teamed up with Pixar Animation Studios to create Pixar in a Box: a free online curriculum that shows how Pixar artists use the concepts we all study in school to create their amazing movies.

Through video lessons, interactive exercises, and hands-on activities, you can learn how Pixar artists use math to solve design problems at each stage of the creative process. In particular, you’ll discover:

- How large swarms of robots in “WALL•E” were designed using combinatorics
- How a field of grass was created in “Brave” using parabolic arcs
- How simple models are transformed into realistic characters using weighted
averages
- How animators bring characters to life with the help of animation curves
- How sets are constructed using geometric transformations
- How all of Pixar’s images are painted using simultaneous equations

But this is just the beginning. In the years ahead, we’ll explore many other subjects, including science, computer science, arts, and humanities.

We’re excited to hear your feedback so we can make Pixar in a Box even better, so let us know what you think in the comments below. We hope you’ll have as much fun exploring Pixar in a Box as we did creating it!

Khan Academy and BELL team up to help kids code

Guest post from Michael Sikora, Director of Communications at BELL (Building Educated Leaders for Life)

“Pick two:  Sculpture, Drawing, Team Sports, Coding, Improv Comedy, Drama, Film Appreciation.”

When the time came for Paolo to select the enrichment activities he wanted to participate in this summer, the opportunity to take a coding class jumped out at him.

“I didn’t really know anything about coding before this summer,” said Paolo. “But I wanted to try it out because I wanted to know how people made video games.”

Along with his peers at Davidson Middle School in San Rafael, California, Paolo learned some of the basics of computer programming as part of his summer learning experience thanks to a collaboration between BELL (Building Educated Leaders for Life) and Khan Academy.

This was the first summer that students – or, “scholars” as they are recognized in BELL’s programs – encountered Khan Academy’s free coding course, Intro to JavaScript, as a summer elective.  The two nonprofit organizations are also expanding individualized learning opportunities for scholars through Khan Academy’s free math resources, based on scholars’ individual needs identified by the results of the pre-program computer adaptive assessments.

Here’s how it all works:  the school leaders and teachers who deliver BELL’s summer learning programs for scholars in grades K-8 can choose to integrate the free Khan Academy math and coding resources into their summer learning plans, based on variables such as scholar needs and technology access.  BELL provides training, instructor guides and resources (such as primers, video tutorials, and sample reports) and ongoing coaching via email and webinars. Teachers, scholars, and parents can all access the math and coding resources, and continue using them after the summer program concludes. In fact, at a site visit at Davidson, Emily Radwin, BELL’s Learning and Assessment Systems specialist, was able to hear from both scholars and staff that many scholars were choosing to work on coding projects at home and on the weekends.

The Khan Academy coding curriculum also allows scholars to work collaboratively in pairs, and has opportunities for scholars to have “free time” and use what they’ve learned to work on free-form coding projects.

“One of the most rewarding things for me is to see the class so engaged by the curriculum,” said Anne Carmin, a teacher at the Davidson Middle School. “Scholars are excited to be here.”

You read that correctly: the opportunity to learn about computer programming, while also honing their academic skills, motivates scholars and makes them excited to spend a big part of their summer – five weeks, five days per week, six hours per day - at school.

“I like that we get to try out new things each day,” said Hendy.  One of his favorite activities was creating clouds with his newfound coding skills.  Jossie agreed.  “I like that we get to try new things here at BELL. When I started with coding, I didn’t know anything about the subject.  I started asking for help, and now I really like it.”

Read more about the summer learning scene in San Rafael in this article by the Marin Independent Journal, and learn more about how the math and coding activities work in BELL’s summer learning programs.

We’re excited to share that, with support from the Amgen Foundation, we’re making lots of new videos, articles, and quizzes to help students taking biology courses at the AP and introductory college levels. Several areas of biology are already complete, and we’ll continue adding more throughout this school year and beyond.

Here’s a more detailed list of the biology topics we’ve revamped so far:

Chemistry of life
Water, acids, and bases
Properties of carbon
Macromolecules
Structure of a cell
Membranes and transport
Cellular and molecular biology
Energy and enzymes

In addition to funding from the Amgen Foundation, scientists from the foundation’s parent company, the biotechnology firm Amgen, are volunteering their time to provide expert quality reviews of our new biology resources to ensure they’re top-notch. “Khan Academy has shown how to leverage technology to put an excellent education in the hands of every student,” says Eduardo Cetlin, president, Amgen Foundation. “We are proud to support Khan Academy in the development and launch of this exciting new biology content and hope these resources will help nurture, engage and inspire many future scientists in the U.S. and across the globe!”

We’re super lucky to have Emily Abrash on our team to lead all of this new biology work. Emily joined us after completing a PhD in biology at Stanford, where she was a biology teaching assistant. Emily also just so happens to be an intrepid cyclist who bikes dozens of miles to work each day!

Stay tuned for updates on new content in other subjects. There’s way more coming soon!


Happy Mole Day from Khan Academy!

As a chemistry nerd, Mole Day is one of my favorite days. What’s a mole, you ask? It’s another name for Avogadro’s number, 6.022 × 1023. And 1023 is today’s date - 10/23 - see how we did that?! Chemists, so creative. So really, it is just a number like a “dozen” or a “pair.” It is actually a really really big number that we could also write out as 602214129000000000000000. In fact, did you know that Avogadro’s number is more than a million times as big as the number of seconds since the Big Bang?

Chemists use moles to make counting easier, like when talking about numbers of atoms or molecules. We can actually count anything in terms of moles, like water molecules. How many molecules are in a cup of water, which holds about 240 g of water? It turns out that a cup of water contains about 8,000,000,000,000,000,000,000,000 molecules of water. That’s a lot of molecules and chemists don’t want to write that out every time, so we can also just call it 13 moles of water instead.

You can learn more about Avogadro’s number and lots of other fun chemistry topics on Khan Academy. Happy Mole Day!

Earlier this year, Khan Academy and Breakthrough Prize challenged teens around the world to share their passion for math and science through video. The results blew us away - more than 2,000 teens from 86 countries submitted videos, bringing challenging concepts and theories to life.

After a peer review, the video submissions were evaluated by the Khan Academy team, Breakthrough Prize laureates, and other leaders in science, technology, and education. We’ve published some of our favorite entries - including winner Ryan Chester’s video about relativity - here.

Congratulations to everyone who participated in this year’s competition - we hope you’ll join us again in 2016!

Many students take chemistry classes, but they aren’t sure how their classroom knowledge might translate into careers in the real world. That’s why we’ve launched our“Meet the chemistry professional” series. We found people working in fields such as medicine, epidemiology, and software engineering, and with cool hobbies ranging from rock climbing to dog training:

Syud Momtaz Ahmed, industrial scientist and tabla player

Andrew Chadeayne, inventor and coonhound trainer

Colin Fuller, software engineer and outdoor enthusiast

Mary O’Reilly, science illustrator and comic strip writer

Rachel Price, engineer and bike-traveler

Jared Roop, forensics/analytical chemist and Cardinals fan

Monica Shah, epidemiologist and bicyclist

Karen Wheeler, physician and long distance runner

George Zaidan, science media jack-of-all-trades and rock climber

We asked each person to share what they work on, how they became interested in chemistry, and what they do for fun. We also asked them to give one piece of advice for people interested in chemistry, and we got some great responses! A few advice snippets that I’d like to share:

“Develop an excellent understanding of the fundamentals. More often than not, the ‘smartest’ person in the room is the one who actually understands everything in a freshman chemistry book.” - Andrew Chadeayne

“Understanding chemistry involves a lot of building mental models and understanding what details are ok to abstract away and what details are important. That’s something that’s useful for many things, like the software development that I do nowadays. Chemistry is great, no matter what you end up doing.” - Colin Fuller

“Chemistry has applications in many careers, so don’t feel limited in scope by the core areas that you study in school. It is also important to gain experience to truly understand how chemistry applies in different settings.” -Monica Shah

“Do what feels right, not what (you think) other people (might) want you to do.” - George Zaidan

We hope you enjoy getting to know these folks, and we look forward to adding more interviews to this series. If you have a chemistry-related career you’d like to learn more about, or if you know someone whom we might include, please let us know in the comments below!

Last spring, we piloted a new kind of math challenge called LearnStorm here in our own backyard, the San Francisco Bay Area. LearnStorm was designed to help students learn how to learn, and it was a runaway success. Over 70,000 students of all ability levels participated, and we were flooded with stories about students who began to love math for the first time.

Now LearnStorm is back for round two, and it’s bigger and better than ever! We’re excited to announce that - in addition to the Bay Area - LearnStorm is also coming to Idaho, the Greater Chicago Area, and all of Ireland! Signups are now open, and the challenge starts January 29.

For more details, or to sign up, visit learnstorm2016.org. You can also like LearnStorm on Facebook and follow us on Twitter for updates.
