Note To Self:
All learning is cooperative. Okay, not so much. All school is cooperative. (Sometimes learning is very anti-social, which is probably why you were better at learning than you ever were at school.) Designating an activity "cooperative learning" makes the assumption that it's okay for some learning to be uncooperative or that you are really okay with uncooperative students. Sorry but you're just not that patient. Call the activity what it is - group work.
