The Khan Academy is a non-profit educational organization, created in 2006 by Bangladeshi American educator Salman Khan. With the stated mission of "providing a high quality education to anyone, anywhere", the website supplies a free online collection of more than 3,200 micro lectures via video tutorials stored on YouTube. It teaches mathematics, physics, chemistry, biology, cosmology, microeconomics, etc
It had all started when Khan started to tutor his cousin through Yahoo's Doodle notepad. After repeated requests from his cousins and other persons who happened to see the videos, Khan decided to post the videos on Youtube. The videos were an instant hit and attracted a lot of viewers.
The basic idea behind the success of Khan's video method is its easiness and flexibility. You can watch the lesson anytime you wish. The videos are also of high quality with humour that doesn't make you feel bored.
These are all apparent reasons. Whats behind the hood? Silently, Khans is revolutionising the education system. A school has created a model where in students are given lectures to be watched as homeworks and actual homeworks are done in the school. This way teachers can interact more with students encouraging them and understand them.
