This is what I worry about the MOOC's: a lot of the best teachers I've had personally, and observed (with children), drew a vast tree of pedagogical techniques, but used their evaluation of a student's individual personality/psychology to inform them of which node/branch to select next. The most sophisticated MOOC's ever get is to brute-force try one node after another, if they support presenting the same material in a different way at all. And there isn't a classification system that I'm aware of to organize all the branches, especially around annotations that say "this branch appropriate if personality/psychology tends towards <this>" (yet another ontological terra incognita, I'm not aware of any classification system to describe students' pedagogical personality/psychology, which can change even depending upon context like subject matter, mood, etc.).

MOOC's are a step in the right direction, but far, far from a Young Lady's Illustrated Primer idealized vision that I would like to see.
