I think I really messed up! In the begining of the year i gave my students a lot of freedom to work in partners and groups but now it's gotten out of hand. When I want them to work independantly the talking doesn't stop. Sometimes when i'm teaching a lesson I can't even get their attention. Many times I will pose a question for discussion and the class breaks into a dozen or so conversations about the question and it is hard to get them back. I feel like they have no respect for me. Do you think this problem can be fixed or is it too late?? Any suggestions?
