BEEPER
I believe that beepers should not be banned in schools. In the modern world beepers are mainstream, it makes human life more convenient. Just like telephone, without that people can't communicate well, students also.
There many reasons to support beepers not being banned in schools. Many students carry beepers because their parents want them to. Parents want to be able to reach their children easily in an emergency. Also, beepers are mainstream in the modern world. If students carry then to schools, students can simply set their pagers on vibrating mode.
Beeper is the best item for communication; it also is mainstream and convenient. It makes students life more comfortable because students can easily communicate with each other, like after school activities. That's why I think beepers should not be banned in schools.
