“Actually, knowledge of the subject being taught is almost irrelevant to the matter at hand,”
Your comment above is beyond the pale of stupid. It’s the kind of thinking put forward by those incompetents who have no comprehension of math or science. Neither can be taught unless knowledgeable in the subject.
Actually, you might want to look into the success of home schooling. We would be at a great loss if Albert Einstein's teachers had not been able to take his thoughts far beyond what they could imagine. Pretty obviously, if anyone listens to your advice they will be severely limited.
My own experience was that the first time I took calculus in college I got a D with the teacher and the text used. So I took it over again, and with a different teacher, I got an F.
After leaving college, I recognized that this would be a block to any advancement in technology. So I consulted a local high school math teacher, borrowed a better book that tied calculus in with analytical geometry, and taught myself two semesters of calculus by tackling every problem in the book, and if I couldn't at first answer one, then I read and pondered on what I read until I understood the principle and answered it correctly. Actually, by completing every answer to every question perfectly, I was able to confidently determine that a few of the text-supplied answers were incorrect, possibly confusing a less able student.
Subsequently I contacted the staff of an excellent engineering college, submitted myself to a discerning four-hour examination prepared by the chairman of the mathematics department, passed it with a grade of 96%, and was invited to matriculate in the fall. To make a long story short, this was the first step in overcoming the obstacles of poor teaching, take advantage of academic resources, satisfy degree requirements through the PhD eventually, and finally retire after serving three prestigious corporations and a well-known university as research scientist.
I also trained my children how to learn, which is the real object of teaching, isn't it? All three are highly-placed officers of technology-driven national or global corporations, and are passing on to their children the ability to learn, of whom several are accomplished college graduates.
According to you, "What a wagon load of crap!"
Well, even crap has value when it is used to fertilize another productive crop of self-starters. Maybe you can come up with yet another of your responses that is "beyond the pale of stupid," eh? (Though you seem to be a rather slow learner, in fact.)
