Mobile Phones

    Currently, the number of students who bring mobile phones to school is increasing. They are allowed to do this by their parents for emergency reasons. From my point of view, bringing mobile phones to school can be accepted, as long as it does not disturb learning activities in the classroom.

    Students commonly go to school and come home without their parents. In this case, I believe that mobile phones are essential. If the students get into some trouble on their way, they can phone their parents immediately.

    Moreover, the parents need to inform their children every time they have to get home late from work. I have no doubt that mobile phones are very useful for parents. Parents can easily contact relatives to take care of their children when they have to be late.

    Nevertheless, what makes mobile phones annoying is the fact that the ringing of the mobile phones can interrupt the learn ing process in the classroom. The students will also lose concentration when they text their friends.

In conclusion, my attitude towards this case is that students can bring their mobile phones to school for emergency cases, as long as they turn them off in the class.
