So, let me give you a little bit of background information. I'd appreciate any and all views on how to handle this situation.
About a month ago, I saw one of my students in the hallway, gripping onto the stairwell railing and sitting on the floor. There were three teachers trying to yank him up; however, he wouldn't get up. I walked on by because I didn't feel it was my business to interfere.
Today, this same student was in one of my sixth grade classes. I was playing a trivia game, where the students were put into groups of four, and were writing down answers on a whiteboard and then revealing the answers after 10 seconds. This particular boy was seated in the front row, about five feet away from me, and wasn't interested in the game, so he took out a pencil and paper. I knew that he had prior anger issues (fighting with teachers in the hallway, and throwing a temper tantrum a few weeks ago during one of my lessons), so I didn't say anything to him about being off track. In most of my classes, as long as the student isn't disrupting other students and stopping others from learning, I don't mind if they need a little break. I figured he wasn't disrupting anyone, so better not to make a big deal of it. After all, I was speaking the questions out loud, as well as the answers, so at least I knew he was listening and involved to some extent. Anyways, my Co-teacher came over and took his pencil away, which by the look on his face I could tell he was really angry. She walked away and he took out another pencil. Again, not speaking, or disrupting. So, she came over and took his notebook, and I'm guessing assumed that he would turn to his group and begin participating. Instead, he sat at his desk, still silent and still angry. My CT saw that he still wasn't participating, came over and PUNCHED him in the head. I'm not talking, a little tap, a full out blow to the head. I was absolutely shocked, and I'm quite sure the class saw my jaw hit the floor. The boy was now at his desk crying, while my CT got in his face and said something in Korean, I'm not sure what. The punch actually made his head jolt.
I know that when I started this job there would be some degree of corporal punishment taking place. I've seen students get knuckled to the forehead, their cheek pinched, and/or have to stand with their hands and feet on the floor, but NEVER have I seen an actual punch to a poor child's head.
At the time, I didn't step in because I thought I shouldn't undermine my CT in front of my class, but after class when the boy wouldn't even look at me, I felt that I had done the wrong thing. I couldn't bring myself to look at my Co-Teacher for the rest of the day. As I said, I know with Korean culture, teachers are allowed to discipline students through physical means, but where does the line get drawn?
I'm not sure if anyone else has had this issue, but any advice on what I should do would be appreciated. Am I supposed to talk to the Principal (which would involve getting another teacher involved to translate), or do I say nothing at all? Should I speak to her? My CT and I have had problems in the past, which is why I didn't say anything today, but the more I think about it, the more I think I should.
Thoughts?
