Diving your class into groups
it's a tightrope when first dividing your class into groups. it can have bad effects on certain members if they feel they have been put into a certain group for a reason.
Maybe an idea would be taking a survey of the class, without the class knowing what this survey would mean ask them who their favorite composer is.
Based on the outcome of the survey, you can use that to make your groups.
I have had fair sucess leting classes break into self choice groups. When I notice a real imbalance of abilities Iwill make some changes by incouraging piticular stndent to take an associate under their wing. Most times they respond quite favorably to the idea they can help.
