Where I used to have to call on students and provoke and pull discussion out of them, the discussions took off. I had assigned student teams to experiment with collaboration using wikis and forums to plan group projects. The presentations that the students gave at the end of the term blew us all away — the other students were as amazed and rapt as I was. So I began thinking about radically changing the way I taught. What about eliminating lectures entirely, and assigning the students to co-teach with me?
