In this case and many other facets of teaching / classroom mgmt / policy / etc..., I can clearly see that there is no ONE perfect solution. Amazing how all sorts of experts, and I'm not talking about anyone on this message board, can claim to have the answers... But every teacher has to find what works for him / herself! I think when my colleagues start filtering back into their classrooms, I will survey a number of them to see how they handle it. I do not want to be the oddball in the faculty but I don't want to have the same problems I had last year. If I am to have the beginning of successful high school teaching, I'll have to stomp my foot somewhere and it will start with a sensible cell phone policy that I can manage and within guidelines.
