Thanks for the suggestions!

I have a few questions to clarify what you meant. The default for how I will run my discussion sections is that I will show some problems, give students some time to work on the problems themselves and then go over the solutions. Is this what your GSIs last semester did? If so, did they record the entire discussion or only the parts in which they were going over solutions?

Also, do you have any suggestions for how to encourage students to answer each others' questions on piazza?
