Educators try to crack down on it because of the cheating angle. I know of one situation where a student got a 0 on her midterm by the school because she was caught with a cell phone in class the day of the exam.
They read her the riot act, and then asked if she wanted to tell her parents about it or if she wanted them to. Those were her choices.
If that is the case how did this girl rackup so much texting when she was in school?
