Hi Mark!
It's true that students in learning groups can get off topic quickly. I have found that clearly defined objectives (desired learning outcomes) helps to keep students focused; I also guide the group to assign roles; one such role is the "evaluator" whose task is to keep the group members on task and on course.
I know you have successfully completed ED108, but I would be interested to hear what methods you have used to ensure that learning groups are effective.
Thanks!
