There is a huge value in learning with instant feedback.

Concepts like edX and online learning will transform education. This will completely change the world. I believe that people will move to online learning, both on campuses and worldwide. We have a real opportunity to be able to bring people around the world into our fold.

We already have a professor who's using an online social network of MIT alums to help educate students in programming. Just imagine expanding that in Facebook-fashion to tens or hundreds of millions of people around the world.

When you're teaching a hard concept and the students all have puzzled looks on their faces and then suddenly you can see that 'aha' moment, that they got it, that's just an incredible thing.

If great lecture is theatre, the future of learning is games.

Online education is like a rising tide, it's going to lift all boats.
