Thanks Andy. I haven’t thought out exactly what this means in terms of what I will do in planning for classes next week. One way might mean that the class as a whole attempts a large bank of problems so there is some group wide accountability or incentive to work through them. The big obstacle I see is that a social classroom is not an environment in which focus is easy to establish or maintain. The mental demand of assembling pens is also low compared to answering questions in math or physics. Those two factors are keeping me from changing my approach completely. That said, there is obviously something here to investigate.
