Thankfully I have had very, few type A personality, angry students. They are the students who become angry when they don't get the perfect grade on an exam or project. They don't blame you. They blame themselves and make sure everyone else feels their frustration and disappointment. Currently, I have this student. The first incidence was the second class period. He took the same quiz that everyone else took. Afterwards, he punished us all for his failing grade eventhough I hadn't graded the exams, yet. His pouting, sideways comments and overall energy vampirism was enough. After class, I took him aside. Expalin what inappropriate, unprofessional behavior he displayed and firmly stated that if he decided to ever act that way in class, I would propmtly ask him to leave. It has been four class periods since and we have had a few outburst. Each time I take him aside and remind him how inappropriate and unprofessional he is behaving.
