text: Using there phones between classes will also help keep students happy and the happier the student is the more likely they are to focus. Even if students were not allowed to bring cell phones to school, they would anyway and then they would use them in class. This just cause more students to get in trouble then necessary. If you do make the rule that students cannot bring cell phones at least consider keeping record of how may times each student has been caught with their cell phone and make it a set number of times they can be caught with it until they are severely punished( at least once).
