Take a moment and remember your favorite teacher – now imagine that teacher could reach, not 30 kids in a classroom, but millions of students all over the world. As we first reported last year, that’s exactly what Sal Khan is doing on his website Khan Academy. With its digital lessons and simple exercises, he’s determined to transform how we learn at every level. One of his most famous pupils, Bill Gates, says Khan — this “teacher to the world,” is giving us all a glimpse of the future of education.
36-year-old Sal Khan may look like a bicycle messenger, but with three degrees from MIT and an MBA from Harvard, his errand is intensely intellectual. In his tiny office above a tea shop in Silicon Valley, he settles in to do what he’s done thousands of times before.
[Sal Khan: We've talked a lot now about the demand curve and consumer surplus. Now let's think about the supply curve.]
He’s recording a 10-minute economics lesson. It’s so simple – all you hear is his voice and all you see is his colorful sketches on a digital blackboard.
[Khan: In this video we are going to talk about the law of demand.]
When Khan finishes the lecture, he uploads it to his website – where it joins the more than 3,000 other lessons he’s done. In just a couple of years he’s gone from having a few hundred pupils to more than six million every month.
