sometimes students engage in rude behaviors because they have become disengaged from the class. This can happen if they are bored, confused or frustrated. It can also happen if the material is sufficiently controversial or sensitive that students become anxious, uncomfortable, or angry. Sometimes students act rudely as a way of registering their disapproval with the course as a whole. This may be particularly true in required courses, but may also occur if students view the class as unfair, irrelevant, or disorganized..
Pay attention to what the behavior is communicating.
If students are behaving rudely, pay attention to additional cues (e.g., body language, facial expressions) to determine the cause. If students look confused, you may have to slow down; if they look bored, you may want to pick up the pace. If they look disgruntled or angry, you may need to ask questions to diagnose areas of misunderstanding or discomfort. You may also want to collect information more formally
