Statement Over the course of 5 days, Junior had 20 tantrums in school. Junio is a 4 year - old who is in my PreK class who throws many tantrums during the day, which includes grabbing my arms so tight that I get nail marks, scratch, lay on the floor, climb on furniture, when he was asked to come to the carpet for our morning routine. Not only does he have tantrums but also nonverbal as well as a runner. Self-injurious behaviors are common in children with autism spectrum disorders. These tantrums are disruptive to the learning of the other children in the classroom, and they keep Junior from learning. I want to conduct this action research because I believe that it may help Junior be more successful and support the learning of the other children. I want to conduct this action research to improve Juniors learning outcome
