I am starting Lit. Study groups and have been trying to gather as much information as I can. I have not done them in a while (this year or last) and was expecting to use roles within the groups, but have come across some sites saying teachers should not use defined roles for the students. What are you opinions? And if you use roles, what roles do you find most useful/effective? I know I am doing Indian in the Cupboard, not sure the other books yet.
