How do you get students to turn off their cell phones and sit facing you?
I have been a long-term substitute in 9th grade physical science at an inner city high school for the past 2-1/2 weeks, but my students have not had a science or a math teacher since September, 2014. I instituted classroom rules at the beginning of my long-term job and updated them yesterday to include consequences and rewards. These rules included the turning off of electronic devices and sitting at the lab tables facing forward, among others. The consequences included deducting points and detention if I have to say something to them two times in a row. These are slowly working, but the cell phones and sitting with their back to me is still a bone of contention. Any suggestions?
