> ...increased data collection on teacher effectiveness, the introduction of performance-based teacher pay... A friend of mine teaches music in a public school, and half of his performance review depends upon his students' math and english scores (à la Common Core). Many of his students were raised in families that don't value education. And if all of that absurdity isn't enough, he's making a lousy salary, with the prospect of making a modest living in five years if he plays the administrative game well and gets a bit lucky. It's not that complicated: if we paid teachers like we pay coders, we would have better teachers. That would cost something like 1% of GDP per capita in the US.
