The Power of Student Teams

"It often happens that two schoolboys can solve difficulties in their work for one another better than the master can. When you took the problem to a master, as we all remember, he was very likely to explain what you understood already, to add a great deal of information which you didn't want, and say nothing at all about the thing that was puzzling you. . . . The fellow-pupil can help more than the master because he knows less." As C.S. Lewis tells us in this quotation, teachers can try too hard: they can focus on teaching rather than learning, on control rather than guidance, on the material rather than the student. Lewis argues, in effect, that too much Teacher can crowd out other important avenues of learning. Finding the Goldilocks mixture of neither too much nor too little Teacher Presence is one of the subtle challenges confronting the instructor and program designer. Here is where using peer-based teaching tactics can help immensely.
