I have noticed what seems to be an inordinate amount of violence at the 7 middle schools I teach at, given the age group and the location (rural Korea). Almost every week, a window is broken, a fight started, or a teacher yelled at, at one or another of my schools.
Maybe I was just sheltered at my private school in middle school, but to me, this seems very odd, and something I would associate more with city schools, if any middle schools at all.
Is this normal?
