> Most of my normal public school classes were nothing more than repetition, rote memorization, and parroting back answers

Doesn't that directly support my point? The school system ends up relying on rote memorization even when it pretends to be all about having the students learn by themselves and exert critical thinking and open inquiry, as advocated for by the most "Progressive" educators! Isn't it then worth it to just get the rote learning part done with in the easiest, quickest and most effective way, by employing the structured approaches that are ignored by most teachers today?
