The best way to raise the quality of teachers would be to fire the bad ones, and then start allowing smart & capable people to teach, regardless of their educational certifications.
No degree in the world tells me who a good teacher is. No credentials in the world tell me what a good teacher is. No union membership tells me who a good teacher is. Yet, you can’t become a teacher without the degree, without the credentials, and without fealty to the unions.
People, in ignorance, keep contending year after year that the reason we don’t have good teachers is because we don’t pay them enough. Yet, time and time again, evidence is plainly available that teacher pay has no correlation whatsoever on student perfomance. The best paid teachers are those that stuck around in massively-subsidized and union-protected billets. These are not necessarily the best teachers-- just the best survivors.
We live in a society where we expect our doctors to not only know medicine, but to safely and effectively practice it. We expect our engineers to not only have professional licenses, they must safely and effectively construct their designs.
Yet, we largely feel that teachers shouldn’t be held to similar standards, for fear of dumbing down education, or-- horrors!-- making school boring. We expect our ideal teachers to be inspirational, outside-the-box thinkers who motivate students through unconventional means to a love of learning. We idealize our teachers in TV and movies-- it’s always the noble teacher arguing how math, or poetry, or dance, or music, or whatever can set children’s minds free. If only our teachers were Mr. Holland, our children would never hate learning again.
This is a fiction, of course, as fictional as the romantic comedies that tell me tubby unshaven guys get the hot lithe girls.
Anyway. . . I’m ranting here, but really, my solution is simple: teaching should be open to everyone who has a modicum of skill and desire to be a teacher-- professionals out of work, retirees, veterans, whomever. Smart people are out of work right now, why not get them a job teaching? Why tell a professional with a master’s degree that he/she can’t be anything more than a substitute high school teacher only because they never took the time to get a two-year master’s in education?
And teaching should be evaluated rigorously, not just based on credentialling and routine benchmarks.
For more on this, I strongly suggest this Malcom Gladwell’s New Yorker article on identifying talented teachers-- and just how hard it is to do.
