Mobile phone at school.

Why we can't take our mobile phones at school.

Now in Spain studients are not allowed to take or use their mobile phones at school, there are some reasons because of this standars:
The mobile phone can be stolen and the school are not going to take care of it.
If we use it in class, we are not going to learn or take advantage of our classes and then we won't know what we have to do. In some cases the mobile phone has been one of the reasons of ciberbullying taking videos, photos...
If all the class forget to turn of the mobile phone it would be a continuous interruption for the class.
