If you're proposing that people have "innate" teaching skills... you're sadly mistaken. With your methodology, you'll have a bunch of type A personality power freaks. Sure all your kids will be quiet but their results will vary widely. How would you deal with a teacher who has perfect classroom control but doesn't improve the students' test scores? You're just using the appearance of discipline and not the actual outcomes. In Asia, I see teachers who have perfect class control and their students are terrible. The schools use your methodology...
There is actual research on what makes an effective teacher and it can be taught. The core of the problem in the US is not the teachers themselves but rather the bureacracy of people who get paid but don't actually teach. You also have parenting problems that are pushed off onto teachers. I think a better approach would be to stop sending kids to school that don't want to be there. This would immediately resolve the discipline problem for most teachers as well as lower their class sizes. There is a direct correlation between teacher effectiveness and class size. There is also a direct correlation between student performance and problems at home. This is the traditional role that education has had before mandatory schooling. I've worked in schools where very few kids wanted to be there but their parents were rich so there they were. It was sort of like a prison for both the teachers and students. I've also taught in institutes with small(10-15) class sizes where everyone wanted to be there. It was a real joy and the students did very well. Instead of spending so much money on security guards, metal detectors, social workers/counselors, principals, vice principals, narcotics officers, truancy officers, etc just SOLVE THE PROBLEM! Perhaps all those kids can become tradesmen or laborers and let the kids who want education get it. If they can't hack a regular academic program, send them to school that can meet their needs. Otherwise, GET THE F OUT OF THE CLASSROOM!!!
