It would be interesting to see if it could be improved on (with actual experimental studies, perhaps?)
As opposed to the non-actual experimental studies findable here?
Ok, I take that part back: I actually haven't researched education experiments. I think there's something wrong with education schools, because they produce teachers who are very ignorant of the material they're supposed to teach (I've seen this firsthand) and because US K-12 students do poorly compared to other countries. So I think it makes sense to be skeptical of education schools' methodology.
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?
