Anyone who has ever taught knows that teaching is not a job everyone can do. My former school had several teaching fellows who knew their subject material inside out but could not handle a classroom. My cousin, a PhD in physics and the smartest person I know died in a high school classroom.
Unfortunately this practice of hiring teachers who know nothing about education is exactly the method being used to hire school administrators right here in NYC, okay, not in all schools. Newbies with a minimum amount of time in the classroom are suddenly in charge to say nothing of the Principal Academy which took no educators and made them the supreme leader of many institutions.
No one would ever go to a doctor who just had a degree in anatomy or use an architect with experience with Legos yet these same people have no problem using teachers with zero education experience or credits.
Limbo lower now--how low can you go?
