One of my freshman math teachers gave grades out for 3 tests and none on homework. He also told us that if we didnt take the first 2 tests, it wouldn't count against us and only the grade on our final would count. Along with that he had extensive open office hours.
It was the math class where I learned the most as well as I wasn't doing rote work and was able to talk to him whenever I had an actual question.
I dont like AI destroying some of our systems but if we return back to the sort of learning that college used to be where it was self directed with guidance from professors, I will count that as a win over the factory worker production system that high school was and universities were starting to ape.
My university math and even my high school calculus class was pretty much like this.
We had homework assigned and in the high school class the teacher spent part of class time reviewing and taking questions about the previous homework set. In the university classes this was done in a discussion section or in office hours.
In high school the homework was supposed to all be in one notebook which would be reviewed periodically but only to see that some effort was being made, it was not graded. It counted maybe 10% of the grade. In the university classes it wasn't even looked at.
The vast majority of the grade was based on quizes and exams, we were typically allowed to bring one standard-sized page of notes for these, and a calculator.
This was all in the 1980s time frame.
