Cell phones can be a distraction in the classroom. Students whose minds wander during a lecture or discussion may find the temptation of texting instead of listening hard to resist. They are also potentially a distraction to the class if the student forgets to set their phone to vibrate rather than ring during calls. Even the vibration can be distracting, and it does not take much for a teacher to lose their momentum. Besides, picture phones and other applications such as calculator in particular can be used to cheat on tests and quizzes.
