"Salman Khan: Let's use video to reinvent education."
Salman Khan presents an effective way of using video to instruct content mastery so that students can watch at their own pace at home. This opens up the class time for activity-based learning, more one-to-one time and peer interaction. I have seen so many attempts to shoe-horn technology into the classroom, this is an example of a way to really use technology to enhance education. This is an inspiring and motivating talk.
