The assignment involves no laptop, no chatbot, and no technology of any kind. In fact, there’s no pen or paper, either. Instead, students in Chris Schaffer’s biomedical engineering class at Cornell University are required to speak directly to an instructor in what he calls an “oral defense.”
It’s a testing method as old as Socrates and making a comeback in the AI age. A growing number of college professors say they are turning to oral exams and combining a variety of old-fashioned and cutting-edge techniques to help address a crisis in higher education. “You won’t be able to AI your way through an oral exam,” says Schaffer, who introduced the oral defense last semester.
Educators are no longer naively wondering if students will use generative AI to do their homework for them. A big question now is how to determine what students are actually learning.
College instructors across the U.S. are noticing troubling new trends as generative artificial intelligence becomes more sophisticated. Take-home essays and other written assignments are coming back perfect. But when students are asked to explain their work, they can’t. The long-term impact of AI use on critical thinking remains to be seen, but educators worry that students increasingly see the hard work of thinking as optional.
At the University of Pennsylvania, Emily Hammer, an associate professor of Middle Eastern Languages and Cultures, now pairs oral exams with written papers in her seminar classes. “It comes across as if we’re trying to prevent cheating,” Hammer says. “That’s not why we’re doing this. We’re doing this because students are actually losing skills, losing cognitive capacity and creativity.”
Hammer forbids AI use on all writing assignments but tells her class she knows she can’t enforce that. However, if they haven’t written their papers themselves, defending the material face-to-face will likely be “a very stressful situation.”
Hammer’s class is part of “a massive shift toward in-person assessments,” both written and oral, at Penn, says Bruce Lenthall, executive director of the school’s Center for Teaching and Learning. The Ivy League school is one of a small but growing number of universities that have started running faculty workshops on oral exams.
