A lot of Rhee-formers have bet that they can improve test scores in school districts by paying good teachers bonuses.
In DC, Atlanta, and many other cities, we now know from Eraser-gate scandals in the news that paying money for good test scores and firing teachers with low student scores will cause a significant number of teachers to cheat.
But a large, three-year study in Nashville, TN, involving hundreds of teachers, and large bonuses, showed that even if everyone is honest, it doesn’t work either. What’s more, even Roland Fryer found it didn’t work in NYC, and that paying students to be good and do their work wasn’t successful, either (“Capital Gains” experiment). Unfortunately, my own blog is one of the few places you’ll find any mention of that.
