I have never used physical force on students, though I have sometimes witnessed it from other teachers. Occasionally my anger at a particularly noisy or unruly class transforms into a loud voice demanding quiet. I will usually try to understand why they are that way. I do not expel or remove students from classrooms. If a student is misbehaving I might admonish him/her, but will take no other action. I can mange to teach a noisy unruly class (though I don’t really like it) by teaching to small groups of students instead of the class as a whole. Sometimes I will conclude the class is just not interested in learning and will decide next time to “dumb-down” with a game or activity that may distract their lack of all attention. I don’t know what other foreign teachers do in these situations, but I will stick to using whatever “psychology” I can. Fortunately, noisy and unruly classes are not the norm. It is a rule for students to misbehave if the teacher is new and inexperienced. Good teachers are universally respected. Students who have teachers who use physical punishment are sometimes a little too anxious to please the foreign teacher, but not unduly. Maybe I’m a welcome relief if they know that I am not going to hit them. Maybe some students misbehave thinking I will send them out of the class, which is what they may want to do, but I don’t do this. It’s very hard to shout in English over a loud class and I have decided it is easier to teach small groups by working around the class than to loose my voice or get sick by shouting. The best way is to avoid this from the beginning by having a lesson planned that will hook their attention. But they are children and they do not have long attention spans. So, have a variety of activities they can do. Yes, but they want to learn and appreciate an activity deeply. It was suggested I just play a video to a “problem class”, or if I was sick or tired I could just play a video. Though I was often sick, I never “just played a video”, but tried to deliver a lesson. Admittedly, I began to use video more in classes that had developed an indifference to foreign English teachers.
