If you think about it, the way we teach now is really primitive. So much feedback could be gathered and incorporated so easily, and greatly increase the effectiveness of the whole process. Imagine something like this incorporated with the Kahn Academy. Also, imagine the feedback being used not only to help the teacher improve the lecture, but also in a "stack overflow" sense to cause the best lecture videos to "rise to the top". I am very excited about what is going to happen in the field of education.
