禁止AI后成绩暴跌50%——学术界是否面临作弊危机？
布朗大学的一项研究发现，当监考考试取代了允许AI使用的开卷考试后，学生平均成绩从96%暴跌至48%，这表明普遍存在的学术不端行为正在挑战传统的评估模式。
a brown university investigation revealed that student grades crashed from a historical high of 96% to a record low of 48.6% after an economics professor moved the final from an unsupervised take-home format to an in-person, proctored setting. the professor noted that students utilized the same obscure mathematical proofs as chatgpt rather than standard methods, and data from 26,000 students in china and 500,000 grades at a us university confirm that ai usage inflates homework scores while degrading actual exam performance. these findings expose a growing disconnect between ai-assisted assignments and genuine learning, forcing institutions to rethink grading policies and assessment integrity.
