I often find that the students that are angry are dealing with traumas and situations that we are not privy to. That makes the situation very delicate, but not impossible to conquer. I tend to remove students that provide a disruption that prohibits learning from going forth. I often realize that the other students are watching and if I do nothing to the student with the disruptive behaviors, then it sends a message that they can too. When it comes to cheating and observing students during an exam, I tend to stand at the front of the class with an occasional walk around. The text suggests standing in the back of the room instead. I will be attempting that strategy to see if it makes a difference.
