I graduated from high school is 1962 and from college in 1966. How does that align with other people's perception of when we started the shift from education to indoctrination?
I'm sure geography plays a role. I graduated High School in 1978, and from my old man recollection, my K-12 education was very "reading, writing, arithmetic". I don't recall being assigned any commiepinkohippie books to read in English/lit classes. I distinctly remember many of my history and government teachers were Veterans who taught what you would call a traditional history with a Western orientation. Math was math, and 2+2=4, and if you said you felt like it should be 5, you failed.
I took around a ten year break between High School and college, and that was an absolute eye-opener. By the time I got to it, the University of Calif system was inundated with hippies, both staff and students. As a science major, I will say that the actual curriculum was still at a high standard. You would have to solve the Earth radiation budget equation by hand (like three pages of equations), however after you did, you had to listen to the professor's diatribe about global warming. So social indoctrination was going on, but at least in the sciences, there was no degradation of instruction, and there were still standardized forms of testing. If you failed, you failed, regardless of gender, race, etc.
Outside of the sciences, I don't know what the educational standards were. Though I recall that at least once a week, and often more, there were some kind of protests going on, almost always with English, feminists studies, creative studies, etc. majors participating.
