I think it's slightly unethical to take it word-for-word without giving a hat tip.

That said, this is a rather remarkable video if, like me, you don't know much about the theory of education (I showed it to a smart friend who teaches undergraduate literature and he said that it was all old hat to him.)

What really stood out to me was the hard data behind Mazur's conclusions -- it's "common sense" that students do better when engaging in the process of learning, but I had never before seen it so convincingly demonstrated.
