Ivy League professor mandates in-person finals over AI cheating fears, resulting in 50% score drop

An Ivy League professor suspected that students were using artificial intelligence to cheat on exams. Consequently, the professor decided to order that the final exam be administered in person. This shift in testing format resulted in a dramatic decrease in student performance on the final. The average scores for the exam reportedly fell by 50% following the return to in-person testing. The significant drop suggests that previous high scores may have been inflated by AI assistance. This incident highlights the difficulties educational institutions face in policing AI usage. It serves as a case study for the potential impact of generative AI on academic assessment. The professor's decision underscores the importance of verifying student work in the AI era.
