"I had a student who yelled in my class. I told them to stop, but they either did not hear me or were ignoring me. I walked up to them and put my hand on their shoulder. It eased the situation and diffused things. I then asked to speak to the student in the hallway so we could have a private conversation and they could calm down. It helped to get the student in a private setting to talk through his feelings. Then, I let him go get a drink and he returned to class ready to work."
