It became a popular idea with people reading from that time because school sitcoms were still a thing. Also, in the movies, the school and students are a secondary element of the main story.
The x-men are heroes and they're meant to fight big robots and aliens and some occasional psycho, not being stuck in a classroom studying or teaching.
To me, the absolute bottom of this insanity was Kitty close to begging Gambit to be a teacher because apparently that was all the contribution he could make to the Xmen to the point they had to create a class for him to be there and somehow he was the unreasonable for wanting to do something else with his life and skills.
