I have to look those terms up later. Sounds like an excellent class. In 1968? Your teacher was prescient, also.
The school district I attended was incredibly good.
So good, that I was spoiled by the time I went to college. I actually thought the professors would be as good as my middle- and high-school teachers. They were not, with one (or perhaps two) exceptions.
I’ve compared notes with my classmates at reunions, and many agree: our teachers were very good back then, were smart and really tried hard to be effective.
