No mobile phones at school
Nowadays more and more students bring their mobile phones to school. While I believe that students should carry mobile phones in case of emergency, I am strongly opposed to these phones being used at school, particularly in the classroom.
Firstly, many students travel to and from school without their parents. Therefore, it is important for them to have a mobile phone in case they need help or have an accident on the way to school or home.
Furthermore, parents who work may need to contact their children. For example, if a parent has to work late, the student has to be told if arrangements have been made for a relative or neighbor to look after them.
On the other hand, nothing is more disruptive during a lesson than the sound of a mobile phone ringing or playing an annoying tune. Moreover, students who send and receive text messages in class are not paying attention to the lesson.
In conclusion, I feel that students should be allowed to take mobile phones to school for use in an emergency. However, all phones should certainly be turned off during lessons.
