If ever there was a useless department in any university, it has to be the Department of Education. They are dedicated to employing the academically unemployable and coming up with new theories and studies rather than enforcing principles and methods that work.
IMHO, future teachers would be better served by majoring in academic studies pertinent to their area (liberal arts, science, math, etc.) and then taking one or two required courses in teaching methods/psychology (6 hours max) in order to be certified. Stop wasting so many class hours on theory and jargon--learn the subjects.
The fact that homeschool teachers/parents have not gone through his self-sustaining department of indoctrination is probably what galls him the most. It must be especially maddening for him to realize that homeschoolers excel as scholars and seldom have a problem beating students from public schools in the academic arena.
