My simple policy for class project groups
September 2015 (perspective of an assistant professor)
Here's my super-simple policy for class project groups:
Everyone forms their own group of 2 or 3 students. To pass the class, you must find a group. The course staff will not intervene in group assignment.
I think this policy works well because:
Note that larger groups (e.g., with 4 to 6 students) means less work for the course staff, since there are fewer groups to supervise and grade. However, I would rather sacrifice some amount of detail in supervision and grading in exchange for students getting to work in smaller groups. I think that's better for students while still keeping a manageable work load for the course staff.
