I was reading a Wired's article on **"How Khan Academy is Changing the Rules of Education" ** features a fifth-grader who's "completed 642 inverse trigonometry problems at Khanacademy.org,". Out of curiosity, i went to the site to see what it is all about. A former boss described Khan as a "natural" teacher and Bill Gates calls him "amazing". I cued up the necessary video and founder Salman Khan's voice, but not his face, filled the screen as his hand worked problems across a chalkboard. I found his content really interesting and with his simple methodology he tried to make his audience understand about the logic he is using. This site address is http://www.khanacademy.org.
