Step-by-step explanation:
In case of an emergency students should be able to have a direct line to their emergency contact. For instance, a school shooting, if no one is able to reach the main office or whatever the case may be danger would only increase. Studies show that phones are actually a way to keep a class more engaged, if the class is aware that if they get their work done they can have a break to do what they please on their device or even listen to music during, that may give incentive to get more work done.
