There is an art to teaching. There really is. How you present a topic to a group of unmotivated high school kids is very different than how you would present that same topic to a group of college majors.
I strongly support using retired engineers and scientists as public school teachers. But without some training, it could be disastrous. I’ve seen that happen!
So what kind of training would be needed? A degree in education? Hell, no! That would pollute their minds. I would suggest instead that they spend a couple of months (yes, months) observing a master teacher in action.

All I have ever asked/expected of an instructor be it high school or college is for them to present the material in an organized fashion. That simple thing seems way beyond almost all the teachers I ever had from high school through college to graduate school. I can count on less then one hand those that approached instruction in an organized way.
