Brown Professor's Anti-AI In-Person Exam Sees Scores Halved
An Ivy League economics professor at Brown University suspected students of using AI to cheat on a take-home midterm exam and subsequently changed the final exam to an in-person format. This decision caused the class average to plummet from 96 to 48 points, nearly halving the scores. The incident highlights an academic integrity crisis triggered by AI tools in higher education and the severe challenges traditional evaluation methods face in the AI era.
Causes and Key Details
According to information provided by several users, the professor noticed abnormally high class averages on the take-home midterm, far exceeding historical levels. In addition, some students' answers featured wording highly similar to ChatGPT, raising strong suspicions that they were using tools like ChatGPT or Claude to cheat.
Responses and Reactions
To combat the potential cheating, the professor shifted to an in-person final exam worth half of the overall grade to compare the score distributions. As authors like @prasadpilla noted, with the exception of a few students, there was a significant discrepancy between most students' midterm and final exam scores. The professor believed that a severe inconsistency in the distributions would confirm the cheating hypothesis. Furthermore, @EchoOfOppenheimer pointed out that the professor sternly warned that the proliferation of AI cheating could lead society toward failure. Multiple posters also used this incident to emphasize the urgent need to rebuild academic integrity in the current technological landscape.
