 I think that cell phones is not a entertainment to students why they are in class.

Students need to be paying attention on classroom instruction without the distractions of cell phones. While cell phones are very convenient and a common part of everyday life, cell phones, for the most part, are a entertainment everywhere. Have you ever been on a bus or plane and somebody is carrying on a loud personal conversation? At a school, the distraction may be even greater than in a public place. For many teachers one of the biggest concerns about including cell phones in schools is that they will be used improperly.It is very necessary to ban the use of cell phone in school to make a healthy and suitable atmosphere.

When a student have a cell phones in school it takes them off track of what they are doing in class. and that students shouldn't have cell phones while they are in class or at school.
