Aaah, life was different inheriting the legacy of the late 60s and early 70s. Most of my schools were not like this, but let me tell you about one year of grade school just for contrast, it was on a native reservation, so it was a little unusual, especially compared to a parochial school i knew with coats and ties, but it was interesting all the same.
We called our teachers by first names. It wasn't disrespectful, but it did instill a great deal of affection and trust in them, including one wonderful elder woman who had to be in her 70s who could teach even grade schoolers to sketch competently. Everything they could try to do differently they did, we'd rotate in groups 2-3 times a day to different teachers in a fairly open space. We learned math not by just memorization but by illustration, practical exercises, and even games and puzzles I spent hours on I'd never have done if it had been "homework". It registered. We learned Newton's laws by firing off a model rocket. Even students could assist in certain contexts. We learned history and archeology not out of text but by listening to speakers and visiting a dig site. The basics were supplemented by elective fun like not just band but drama in which we wrote and produced our own plays. It was fun getting taught by the hippie types ;-)
You had touches of that into the early 80s - math and others were out of normal texts, but in English if you were advanced enough, you could do independent study, deciding what book you'd read for that week with a teacher and writing a competent 5-page paper - good prep for college. Language classes were supplemented with visits to places you really did have to speak the language - it wasn't just pass some written test, you had to get the idea you needed to speak this subject the same way you spoke English. I kicked the AP exam's butt around the block and back.
I definitely think that era did good things for education, although ultimately the most important thing is less the method or the philosophy than the enthusiasm of the teacher.
