Instead of trying to fire our way to the high performance of Finland or anywhere else, why not try to emulate the policies that these nations actually employ? It seems very strange to shoot for the achievement levels of these nations by doing the exact opposite of what they do.
In any case, Gates, Rhee, et al. constantly repeat the “fire 5-10 percent” talking point, along with the promise of miracle results, because of its potent political message: all we have to do is fire bad teachers, and everything will be fixed. They use Hanushek’s calculation to provide an empirical basis for this message. They do not, however, seem at all attuned to the fact that the proposal is less an actual policy recommendation than a stylistic illustration of the wide variation in teacher effects.
Let’s stick with meaningful conversations about how to identify, improve, and, failing that, remove ineffective teachers. Test-based measures may have a role in the evaluation of both teachers and overall school performance, but not a dominant one, and certainly not an exclusive one.
Does it bother anyone else that Gates and Rhee and Christie and all the other 'formers seem to care more about punishing "bad" teachers than upgrading the profession?Systematically firing large numbers of teachers based solely on test scores is an incredibly crude, blunt instrument, fraught with risk. We’re better than that.
