I have some of the same feelings on post-conferences. It can be valuable, but not if the students don't want to be there! I have two clinical days a week. On the first day we stay for a traditional post conference. On the second day, Friday, I had too much trouble keeping the students engaged. On this day, I give them an online discussion board post-conference assignment. This still allows for interaction between the students, but I give them until Sunday night to complete it.
