Summary
Because AI-written texts are relatively easy to present convincingly, detecting AI use in student work is becoming increasingly difficult. The article argues that oral assessments (discussions, interrogations, viva voce) expose a student’s reasoning in ways AI can’t mimic. Voice, hesitation, follow-up questioning and depth of thought are far harder for AI to fake in real time. The authors suggest reintroducing or strengthening oral exams and conversational assessments as a countermeasure to maintain academic integrity and ensure authentic student understanding.
Key Points
- AI tools produce polished text, but they fail when asked to defend their reasoning under questioning.
- Oral tests can force students to show understanding, not just output.
- Real-time dialogue gives instructors more confidence about authenticity than text alone.
- Reintroduction of oral assessment may help bridge the integrity gap in AI-era classrooms.
- The method isn’t perfect, but it is a practical and historically grounded safeguard.
