YouTube - Khan Academy

This video is about the Khan Academy. How it started and where it is up to. Basically Sal uses YouTube as the blackboard to teach kids maths. This is good, not only because of his style, but the kids can stop, rewind and try again. Sal has enhanced the videos with a self paced program which provides data for the teacher to target developmental areas. This program is in some school districts in the US where the kids do the online activities at home leaving the classroom free for higher order thinking. Check out the website, even just to test your own numercy skills.
