I have a lot of group work structures in my classroom. Science is a collaborative activity, and I believe students learn more when they talk to each other and use the vocabulary and discuss ideas. However I have had a few students this year who all but self-destruct when they're required to work in groups. They want to do everything on their own, and rush ahead of the others. They don't want to speak to each other, or share their responses. One student was on an IEP and that kind of made sense that he was just anti-social, but another student was not on an IEP and I could see him getting more and more frustrated each time I asked him to work collaboratively with his group. The way my groups are structured are that each person has a role: reader (reads the questions and passages), manager (keeps everyone moving at a good pace), document control (makes sure everyone is working at the same pace and on the same question), or spokesperson (shares responses with others or me). I also have them split their handout down the middle, and do a quick-write of each question before coming together and coming to a consensus with the rest of the group as to what the answer is. The consensus needs to be written the same exact way for everyone in the group. I find I have to be strict with my group work procedures or one person will just complete the entire thing on their own and everyone else will copy with little to no discussion or learning happening. I believe my structures make group work as effective as they can be, but they seem to frustrate the "good" students who are used to just getting everything done on their own without having to work as a team to make sure everyone is learning and contributing. To them, they just want to race to the finish line. I feel bad, because these students do do well on their own without doing group work, but I think they would benefit from doing group work. I feel like the bad guy when a kid gets as frustrated as he did today to the point where he had to sit outside, and wouldn't talk to me (this is a sophomore!). Thoughts?
