Some professors are geniuses at communicating their subject matter and some are dolts.
Video tape, VCR, Youtube...that is the medium for communication geniuses. The best excel and the worst die a painful death!
Condolences for your faves!
Decades ago there were teachers who taught in one-room schoolhouses. Their students all managed to earn Regents diplomas or the equivalent.
The difference? The students were motivated.
It has never been demonstrated that teachers with a degree from a school of education provide a better education.
Sorry not getting down on your level.
