The Ground Rules in the Classroom

I was wondering if there was anything part of your program that kind of mitigated against that. I wouldn't say that you could necessarily mitigate against it other than through this use of ground rule, which is all set up to facilitate cooperation and fairness in practice. And especially if you give one person in the group the role of making sure that the ground rules are being followed. So that helps because one of them has got the sort of slight role of a policeman.
