The Teacher’s Job is to Explain— To “Make Plain”

I have made the claim before that a teacher is essentially an “explainer.” I’ve sometimes felt some resistance from others to that claim, and I think I know why. When I state that a teacher is an “explainer,” for some it conjurers up an image of a dry, boring lecture such as the case of the economics teacher (played by Ben Stein) in Ferris Bueller's Day Off (“anyone, anyone…”). This is not my idea of an “explainer,” so let me try to “explain” my claim below.
