I think that the Khan Acandemy is an amazing idea. I did understand what he was telling me. I like how if i didnt get something i could just pause it or rewind it. Another good thing is that they put Q&A and the bottom of the page for its like your pretty much in class learning from other people still. If I was a teacher and one of my students was going to be out for a week or more i would defliently have them use this web site also when i have subs. I deflitnly think that some of the classes should use this !
