They may be more positive. They certainly haven t declined. Some students really like the group work while some students really like lectures and wish I did that more. I have found, however, that the evaluations given at GSU are very different than at Purdue and since I switched schools and teaching styles simultaneously, I have had a hard time distinguishing between the two factors. I have lower course evaluations scores now.
More positive comments mention group work and projects.
As usual some students like the cooperative learning environment and others felt the teacher was failing to meet their obligations of presentation of material. Too many different things to go on. I changed from a research University to a liberal arts college, then I tried cooperative learning. Students seemed more positive in the course evaluations. Students are generally positive about the cooperative learning and say so.
