Researchers at the University of Reading conducted a groundbreaking experiment where they successfully deceived their own professors by secretly submitting AI-generated exam answers that remained undetected and achieved higher grades than those of actual students.
In this project, the researchers created fictitious student identities to submit unaltered responses generated by ChatGPT-4 in online assessments for undergraduate courses. Despite the university markers not being informed about the experiment, only one out of 33 submissions generated by AI was flagged, with the remaining entries receiving above-average grades compared to human students.
The findings of the study indicate that AI systems like ChatGPT are now passing what is akin to a “Turing test,” named after Alan Turing, a pioneer in computing, by being able to evade detection by experienced evaluators.
Described as the “largest and most rigorous blind study of its kind,” the research highlights significant implications for how educational institutions assess students. Dr. Peter Scarfe, an associate professor at Reading’s school of psychology and clinical language sciences and one of the study’s authors, emphasized the international importance of understanding how AI impacts the integrity of educational assessments.
“Our research demonstrates the critical need to evolve educational practices in response to AI advancements,” Dr. Scarfe noted. “While we may not revert entirely to handwritten exams, the global education sector must adapt.”
The study concludes with a warning that as AI’s ability to demonstrate abstract reasoning improves and its detectability diminishes, academic integrity concerns will escalate. Experts, including Prof. Karen Yeung from the University of Birmingham, assert that such findings signal the potential demise of unsupervised coursework or take-home exams due to the ease with which generative AI tools facilitate cheating.
Looking ahead, the authors suggest that universities may need to redefine how AI-generated content is incorporated into assessments. Prof. Etienne Roesch, another author of the study, underscores the necessity for clear guidelines on AI usage to prevent broader societal trust issues.
Despite these advancements, Prof. Elizabeth McCrum, Reading’s pro-vice-chancellor for education, acknowledged the university’s shift away from unsupervised online exams toward more interactive assessments that apply knowledge in practical settings.
However, concerns remain regarding the implications of integrating AI into educational assessments, with Prof. Yeung cautioning against potential “deskilling” effects among students overly reliant on AI tools.
In an intriguing footnote, the authors playfully query whether using AI in preparing and writing their research could be perceived as “cheating,” prompting reflection on the ethical dimensions of AI’s role in academic research.
A spokesperson for the University of Reading confirmed the study’s human authorship, responding to lingering questions about the potential involvement of AI in its production.
