Just as computer science is missing from our school system, so is science fiction.

There are things you can get in that physical experience you cannot get virtually.

There is too much acceptance of people saying, 'I am a math person, or I am an artsy person.' It makes me cringe.

If a student has access to a great school, Khan Academy can supercharge it. It should help a well-resourced school, and if you don't have that, then Khan Academy can have even a bigger impact. But I don't see it as replacing the actual schools... we want to empower teachers and fill in the gaps.

Teachers can use technology-based assessments to inform their instruction. These assessments can quickly produce data and surface patterns that help teachers identify where students are faltering and intervene with targeted coaching immediately, before the student falls too far behind.

All too often, technology is treated as a silver bullet for perceived problems in education. This sometimes leads to knee-jerk investments, using scarce resources to invest in software or hardware without a clear notion of how either might actually empower learning.

Later in life, when my kids struggle to understand a tricky concept or master a new skill, I want them to have the strength and experience to tell themselves, 'I don't know how to do this... yet!' I want them to be confident that, even if something seems challenging today, they have what it takes to figure it out.

As my kids grow up, I think a lot about the lessons and values I want to impart to them. More than any particular skill or even financial support, I believe perseverance and resilience will serve them best, regardless of what curveball life inevitably throws them.

Rather than saying, 'I can't do this,' 'Sesame Street' encourages us to say, 'I can't do this... yet!' That one word changes everything. It emphasizes that your capability isn't fixed. It highlights the reality that our brain is like a muscle.

When I used to try and describe what the Khan Academy was, I would tell people that if it were a for-profit, I would be on the cover of 'Forbes.'

Being a billionaire is sort of passe.

By early 2009, tens of thousands of students were watching tutorials on the Khan Academy every day. The software I wrote for my cousins had become so popular, it was making my $50-a-month web host crash. The possibilities surrounding the academy were so exciting that I had trouble doing my day job properly. And soon, I quit.

We don't believe that you should ever replace physical education. Even in a thousand years, a computer will never be able to do so.

I realized that there are many people who are very good students, but they think of themselves as bad students. At the end of the day, what they are really missing is way to understand where their gaps are and a way to address those gaps.

I've learned that certain things are much harder than when you write about them in a book.

I never viewed technology as a replacement for the human experience. I viewed it as something that could liberate the human experience.

A lot of times, when kids have problems with algebra or trigonometry, it has nothing to do with the subject matter, has nothing to do with their innate intelligence. It's just they that they had some gaps in elementary school that they never got to fill in.

It's an old idea. It's arguably the first way that people learn, that, hey, if you need to learn something, if you're having trouble with it, keep working on it until you master it and then you go to a more advanced concept. But in the education systems that all of us grew up in, we all learned at a fixed pace.

What you have in most education software is that they're catering to the decision-maker who makes the budget allocations, and that decision-maker has a lot of check boxes. Does it do this? Check. Does it do that? Check. They could care less about the end user experience.

Our mission at Khan Academy is a free, world-class education for anyone, anywhere, and college readiness is a crucial part of that. We want to help as many students as possible prepare for college and for life, and since the SAT measures preparedness for college, our partnership with the College Board is a natural fit.
