Making teaching teachable
Many of our recent ed-reforms—e.g. Teach for America, alternative certification, the Hamilton Project, and various “new teacher” projects—implicitly subscribe to the idea that great teachers are born, not made. Ed schools, too, largely consider “training” teachers to be beneath their dignity. Hence the path to instructional excellence is to welcome all sorts of smart people into the classroom via all sorts of entry paths, then weed out those who don’t cut it.
