How I changed teaching after AI managed to do all my homework assignments

A course instructor replaced written reflections with short live conversations because AI could produce the written answers. In their account of the course redesign, each student schedules a 15-minute meeting with a teaching assistant after an assignment, and the assistants challenge them with follow-up questions about what they submitted.

AI is permitted on assignments, in any form and without attribution, except on written and oral exams, so these conversations are what check the student's understanding. The arrangement relies on teaching-assistant time: the course runs at about 20 students per assistant with roughly 10 hours of work per assistant each week. The instructor also writes that they cannot measure whether students learn more or less under the revised system.
