I dunno, I think it’s a bit more clever and less desperate than that. The teacher knows the kids are saying it a lot. Getting them to even lightly associate it with their learning objectives will help at least some kids academically. Mnemonics are stronger when they are memorable and repeatable after all.

There is no way the teacher thinks this will make learning “cool”. And the fact that co-opting it speeds up the process that skibidi will become “uncool” is probably just a fringe benefit to the teacher. Really, it’s a masterclass in psychology, a win-win.
