Smart phones in school

Nowadays in all schools mobile phones are not allowed because it is believed that students will use them badly.

Indeed students would use the phone to chat to each other but also they could work easily with it. In fact we could use phones in the same way as we use the computers, so schools would save more money than they do because most of the people, except children, already have a personal smart phone and they can use it to explore in the internet instead of using computers.

 If schools do that, they have the risk of teenagers taking photos of their teachers or they could use the phone to copy in the exams.

In conclusion, we could say that for using mobile phones instead of computers, they should look first to the pros and cons of it.
