How a math challenge can teach more than just math

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!

Khan Academy helps students prepare for medical school admission test

image

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!

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.

A big thanks to our early reviewers for all their great feedback:

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.
