Fudan Exam Lets Students Design Questions to Stump AI
复旦期末考改革：学生出题考 AI，难倒模型得分高 ⭐️ 8.0/10

Fudan University replaced its traditional 'Data Mining Techniques' final exam with a human-versus-AI challenge, where 51 students each created 10 computation problems to test three AI models, earning higher scores for stumping the models. Results showed that 50 students stumped at least one model, but only 4 managed to make any model score zero on a full paper, and the strongest model, Claude, was never completely defeated. This novel assessment reflects a paradigm shift in education as AI makes traditional memorization-based exams obsolete, emphasizing instead the ability to evaluate, judge, and think critically. It directly addresses how universities can adapt curricula to an AI-driven world, potentially influencing pedagogical approaches globally. The exam involved 51 students generating 10 calculation problems each against three unnamed AI models, with Claude (by Anthropic) being the most robust. The class average score was 85.7 out of 100, and the instructor noted that future assessments will focus on commanding AI and judging its output rather than on algorithmic execution.

telegram · zaihuapd · Jul 5, 08:40

Background: Large language models (LLMs) like Claude are trained on vast text data to generate human-like responses. Adversarial testing is a method where inputs are deliberately designed to stress-test an AI model's assumptions and find its weaknesses. Fudan's exam effectively applied adversarial testing in an educational context, reversing the usual role of students from being tested by AI to testing AI.
