Khan’s calling

Salman Khan’s found a new calling: teaching.
I am, of course, talking about Salman Khan the hedge fund manager turned online tutor and not about the muscle-bound Indian actor. This Salman Khan is the founder of Khan Academy, an online library of short, free lectures on a handful of subjects including algebra, economics, history and science.
The 1,800-plus videos on the site — on YouTube actually — are between 10 and 20 minutes long and lean towards quantitative-oriented subjects. Each clip breaks a specific topic down into easily understandable bits. Khan plays teacher, explaining things orally, while also using an electronic blackboard with doodles and pictures to illustrate what he’s talking about. Not very hi-tech, but interesting and effective.
Do check out the Khan Academy. Oh, and Sal Khan is touted as ‘Bill Gates’ Favourite Teacher’.
