 The important thing to realize is right now in a traditional classroom, kids go and even though there's human beings in the room, it's actually a fundamentally dehumanizing experience because even worse than sitting in front of a computer is sitting in a room with 30 people and not being allowed to interact with them. Not being allowed to talk to your peers, teach your peers, learn from your peers, object with your peers, not being able really to interact with the teacher. Some people sometimes say, well, you know, in a lot of you can ask questions. But what I point out is, yes, I agree, and questions are a good part of a live lecture. But for most of a live lecture, especially at the university level, you'll have 300 people sitting in a room and they're there passively listening, you know, trying, taking notes to really just to stay awake. The teacher is oftentimes just going through the motions. What we think is if a lot of the information delivery aspect can happen in an on-demand nature, a lot of the traditional problem sets, homework can happen in an on-demand nature, what it does is it frees the physical classroom to be about exactly what I believe Suzanne mentioned, face learning, more peer-to-peer interaction.
