You do have a point about differing cultural approaches, but after a generation or two, it seems like culture and socioeconomic status would correlate.
Right, but they would need to be identical, not just correlate, for a model that only includes one to be as good as a model that includes both.
I want to learn what's well-understood about education. I expect to launch myself into some endeavors in teaching the first few levels of epistemic and instrumental rationality - ie., critical thinking and problem solving. I'm a little suspicious, though, of the scattered educational texts that I've so far read. In particular, education seems like a field where it's easy to have motivated thoughts, and hard to gather good data.
With my background (Math and CS) I'm a little at sea in educational literature. Does anyone know of good, reductionist-grade or evidential-grade, introductory texts in education?
