I believe phones are very essential due to many reasons. Phones can help us learn without disrupting class. Students seem to feel more comfortable with cell phones at their sides. There are also many learning apps that can help make everything a more hands-on experience. You can take it home for help without breaking your back with 20 pound books. Students may use them in case of emergencies. Also, (I just HAVE to say this) I believe that students should be able to use them appropriately in their free time. One more thing. They shouldn't get their phones TAKEN AWAY!!!!!!!! I cannot stress this enough. To fix this problem make them sit through a boring a hard task cell-phone etiquette class.
Students should not use cell phones, and rather use iPads. Students would text each other in class and would be able to get away with it. Also, not all students have cell phones, so it will be unfair. iPads can have restrictions that would help teachers. It is a lot easier to get away with messing around with a phone, rather then an iPad.
