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.
Very few are negative, or if they are, they do not mention it on evaluations. Several students commented that I must not explain the material as well because more of my students attended the cooperative learning study sessions. However, since I organize these, I also promote these heavily. This probably lowers teaching evaluations - especially if the students haven t been subjected to it before. No, but again I used it for a very select group.
