Imagine grading a college exam and discovering that nearly half the students earned perfect scores. For a professor, that might ordinarily be cause for celebration. But at Brown University, economics professor Roberto Serrano became suspicious when 40 students scored 100 on a take-home midterm in his advanced mathematical economics course. Some answers closely resembled responses generated by ChatGPT, prompting concerns about widespread AI-assisted cheating. According to EL PAÍS, Serrano believes at least 50 students cheated. When he required an in-person final exam, the class average plunged from 96 to 48, and 22 students who had previously earned perfect midterm scores did not show up. The results raise troubling questions about how much students are actually learning when artificial intelligence can complete increasingly sophisticated academic work.
