If you ever wonder if you or another educator is clueless about classroom management, just ask yourself (or the other person) what the best classroom management plan would be. If the answer you get is to have a great lesson then you are clueless.
There are two cases when this method would actually work: 1) If you are a natural at classroom management (which includes very few people) and 2) If your lessons are compelling and entertaining 100% of the time (which includes no one).
Most teachers are not in either of these two categories.
One of the best ways to reduce stress from public speaking and teaching is to be prepared. Have a classroom management plan from the beginning. Know what you will do ahead of time to handle any potential behavior problem.
You will have much less stress having a specific plan ahead of time than you will if you try to handle misbehavior as it happens.
