I had a teacher telling us to change a 120 pages long document back and forth three times. The third time we showed her the hardcopies with her revisions and hand waved it away, trying to gaslight saying it wasn't her handwriting(!). Same person saying that the hardcopy we had of the OMG.org specs[1] was wrong (same class, I believe it was a different day) because she wanted Use Case Diagram[2] didn't have arrows denoting directionality (Use Case Diagrams do not have directionality, they just represent interactions). It's one of the two teachers I've ever walked out in the middle of a class in my life.

(The other was one in an engineering thesis orientation class where one of the "teachers" said that "everything that could be invented has already been invented". I walked out immediately, followed by a few other people seconds later after some other comment.)

Huh, teachers. I had one teaching computer architecture who treated Linda Null's book as a Holy Bible of the course. She liked to correct students by saying "you're wrong, you haven't read Linda Null, go read the book". It was fine until the point when she disagreed with what someone wrote on the test - and when that person has pointed out that it's straight from the book, she shrugged and said, "well, Linda Null is wrong". sigh

I think it was somewhere in middle school where I had several teachers who insisted that there had to be corrections made between a rough draft and a final draft of a paper, because thirteen-year-olds were obviously incapable of getting anything right the first time. I would write a paper, save it, introduce a few typos, submit that as the first draft, then submit the original a few days later when the final draft was called for.

That reminds me of an English paper I had in freshman year of high school. Final grade on the rubric: 6/6 for each category, but 3/6 for "revisions" because I didn't change anything. Final grade B-.
