Here is a relevant quote from the TFA:
> Although students were permitted to use AI to brainstorm topics and identify sources, in this instance the students had indiscriminately copied and pasted text from the AI application, including citations to nonexistent books (i.e., AI hallucinations).
(And re better rating: sadly making classes less useful usually improves the rating. I sure if there was a class where they were just watching cartoons, with super-simple quizzes at the end that everyone could answer, it'd have highest ratings from most students, as well as high ratings from many parents, and best scores on finals. Now, it might not work that hot in real world, but by that time the school would be long over...)
