The first reason why cooperative learning doesn't work for everyone I can relate to. Some students like to work alone (educational psychology), I found that when I was forced to work in a group I was less active than if I worked on the assignment alone. By pairing more qualified students with less qualified students, this could help less qualified students feel that grouping these two together could hold back more qualified students. I've also been in groups where when work is given out for use we simply don't do it. We prefer to sit and socialize rather than work. I believe this often happens with cooperative learning when students are placed in groups with their friends. According to wcer.wisc.edu, cooperative learning can break down when one student tries to take control of the group. This does not allow all students to participate in the work and power is not balanced, which could cause problems when working in groups. Another problem that the cooperative learning system might have is that people in the group don't get along. I could see this as a problem in higher grades like 9th-12th grade because when students don't like each other in high school it is very difficult to get them to work together to successfully complete a task. Finally, one of the most common problems I have encountered when working in groups is that students will participate in “social” activities”.
