<p>I have a very stick class room policy ( set by the department head) that no cell phone are to be used in class.&nbsp; It has not at this time caused any significant problems.&nbsp; Yes I have had to tell a student to put it up but not in a shaming way I make it very matter of fact.&nbsp; I have subtituted for a teacher that did not enforce this policy and the students seemed distacted and unconnected to the class or the class dicussion.&nbsp; This class has been a continueing issue because rules that are policy are not enforced and they have no shown a significant respect for this teacher or the school.&nbsp; Seeing this from both enforcing policies and policies that someone let slide the students are signifacantly different!!</p>
