Hi Brant!
You are exactly right and no matter how hard an instructor works to prevent this from happening invariably it does. I like forming a group of no more that 3 students on the second day of class. Discuss the importance of group work and the group process. Then have them to work together as a team from the beginning. This enables the students to get to know each other and - I feel - helps them to become more synergistic.
Any other ideas out them?
Keep up the good work!
