Well, point number 1 is why teachers aren't in favor of the current administrative fervor for it, at any rate.
I agree with Bostonian's post in its entirety. It can be good for autodidacts, assuming that the curriculum is current and high-quality (which I think that Val and I have shown is not always the case, in spite of assurances to the contrary).
It's pretty toxic for Socratic or top-down/big-picture learners, though. Far more so than I would ever have imagined without knowing my own child as a learner.
