If you haven't been at the front of a K12 classroom (and I mean really in front, not the guest lecturer with the teacher in the room to keep things in order), you're not qualified to make that statement. The fact of the matter is that you're with a room full of children. If you can't manage them you can't teach them. Without classroom management, you will fail at everything else. It's easy to forget this when you see a skilled/experienced teacher at the front of the room. They've internalized the management to a level that makes it almost invisible to an onlooker, but it's very much there.
