I have been known to berate the quality of classroom discussions—student-teacher exchanges that occur in the presence of mostly uninvolved others. Perhaps instead of berating I ought to be trying to help faculty improve how they lead discussions, and that has gotten me thinking about all the details discussion leaders must keep track of and make decisions about — all on the fly. Leading discussions effectively is not an easy task for any of us. Even those who make it look easy have actually worked very hard to hone this important skill.
