The Khan Academy started by Salman Khan, a Harvard Business School alum takes a radically different approach to education.
Salman was working as a hedge fund analyst and was remotely tutoring his cousins and once his tutorials got a little famous, he ended up delivering the same (read: repetitive) tutoring to other students.
He started recording the videos and put up the tutorials on Youtube. Initially, he started creating tutions using Microsoft Paint (black background/florescent colors) and later moved to sophisticated software donated by the site viewers.
Salman covers pretty much all the range student asks for – mathematics to Economics, Algebra, Trigonometry, Physics, Chemisty etc.
Whats amazing about Khan academy is the simplicity of operation – its a one man show. As of writing this article, there were 13 million views of the academy videos on Youtube; and the videos are visited by 100,000 students a month, averaging around 40,000 video views a day!
