We just had our third presentation day in complex analysis. So far, things are mostly going well. The document camera is working very well now, and is saving a lot of time; we can do about eight presentations in fifty minutes.
I am still looking for a way to increase audience discussion (which would reduce the amount of presentations we could do). Most presentations have no questions following them. However, whenever there is a mistake, we have picked up on it. My best guess is that there are no questions because people generally understand the presentations. Students tend to work on the same problems, and—in many cases—work together to solve the problems. Also, the content for the first two presentations was not been terribly difficult.
That said, I threw – proofs at them yesterday. Only two of the students have had real analysis, although I think that most of the students probably have seen them in our Introduction to Proofs course (although I am not certain—we have a lot of physics majors in this class). But students did remarkably well figuring out how to do them. I will ask them next time why they were so successful.
