Teachers are people; people are subject to human foibles and failings across the spectrum. I have no quarrel with teachers here.
What I quarrel with is that subset of people who don’t believe in math:
A gubernatorial investigation found in 2011, after looking closely at erasure marks on test sheets, that more than half of Atlanta’s elementary and middle schools contained classrooms with an average number of wrong-to-right corrections more than three standard deviations above the state average.
We can tell if a kid is cheating. Or a teacher. We can tell if a teachers adds to or detracts from a year of instruction.
Pay the best like rock stars – fire the worst.
