Yes, I have tried the homework quiz. I don't think all the kids really thought I was going to do it. I had a lot of them fail it. However, on the other hand, those students that do well did. They are still confused with the idea that I am not picking up their homework nor am I checking it daily. We do go over the homework daily, I just don't spend all that time to check it anymore.
I am planning another quiz probably late this week. I bet they do better..
