This is one of those why-didn’t-anyone-think-of-that stories about what is rapidly becoming the most influential teaching organization on the planet. Salman Khan was a hedge fund analyst educated at MIT and living in Boston in the summer of 2004. The job was okay but he so much more enjoyed recording Web videos to tutor his younger cousins in New Orleans in math and science. Other people started asking him for tutoring help so started putting math videos up on YouTube. He’d put 70 videos up in a row on algebra, geometry and calculus. Soon a lot of people started watching the Khan Academy–our Name You Need to Know in education.
Since Khan started putting videos up, his Khan Academy videos have been watched 24 million times. You Tube told him he has the most popular open-course video library on its site, with more views than MIT, Stanford or UC-Berkeley. Khan has produced 1,600 videos so far, all simple 8- to 20 minute takes on subjects such as torque, ebitda, debt loops, probability, exchange rates, the Paulson bailout, binomials and the battle of Trafalgar. Khan records each himself. You never see him. You only hear his baritone and watch the trail of his track pad pen scribbling on a black screen.Click here to read more
