AI禁止で成績が50%低下 — 学界はカンニング危機に直面しているのか?
Brown大学の研究では、AI使用可の持ち帰りテストを監督付き試験に置き換えたところ、成績が96%から48%へ激減。学業不正の蔓延を示し、従来の評価モデルに疑問を投げかけている。
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.
