We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Why Einstein Was Not Qualified To Teach High-School Physics.
Not that simple. Yes, the education bureaucrats' requirements can be stifling. At the same time, a lot of states have short-term training programs for prospective teachers who already have a bachelor's degree and work experience.
But those who can walk in cold into a classroom and succeed without any previous instruction in pedagogy are few and far between. At least that is my experience. Coincidentally, high school physics would likely be the field in which a newby teacher who knows the subject matter would have the greatest chance of success, as you are dealing with students who are more mature and more committed.
I spent two years as a second-career math teacher. Pedagogy is important, as it is NOT intuitively obvious how to present different teaching materials to different age and ability levels. Unfortunately, the ed schools are totally inept at pedagogy, as they emphasize politically correct nonsense and the unproven teaching theory fad of the year instead of WHAT HAS BEEN PROVEN TO WORK in the classroom. Very little of what ed schools present to prospective teachers is actually useful- which is my guess why the linked article stated that there was little difference in performance between certified and uncertified teachers. There is useful material that ed schools could present to teachers- they just don't do it.
My guess is that some sort of apprenticeship would be a good way to train prospective teachers. I would also suggest a part time load with heavy mentoring for beginning teachers.
Have you looked at this union boss Trumka? He looks like a prototypical union thug. His forehead is only about half an inch high and is prognathous. Not only would I fear to get on an elevator with him, I would fear being in the same room with him. He makes all the longshoremen thugs of my youth look like Sunday school teachers. Not only was he behind the door when Mom Nature handed out the good looks to the new babies, he was not even in the same building.
