Thank you Dr. Meers for your comment to my question, I think the method would be fun to try!

It is usually a challenge the first class day to establish yourself as the "manager" of the course, when their are various student's that have already, set their opinions of either fellow peers, previous intructors and bunch themselves into these cohorts. What are some techniques you have learned to either heal the group(s) without offending anyone or starting a debate, but standing your ground on classroom behavior and respect for others.
