Occasionally my sensei will ask me to demonstrate and coach a group of youngsters in his karate class, something I am happy to do. However, I have noticed a pattern of behaviour with the students which I find very annoying to say the least and I wondered if any experienced teachers had any tips or hints. I seem to spend the lesson continually shushing my students and trying to maintain discipline, it makes me feel like a substitute teacher at an inner city high school and its beginning to get me down. I don't notice any of the other senior students having similar problems. I don't want to just give up (I never gave up on a challenge in my life). I talked to my sensei and he isn't really helping, he just seems to think I will get the hang of it.
