Q&A

I used to rely on essays written at home for course grades, but now with AI provided even by the university (and knowing that AI detectors do not work) this does not work any more. How should I redesign my assessment?

My student submitted a text and I am 99% sure that it is written by AI. It uses all those words that are all over AI-generated texts, like “thus”, and “leverage”, and I just feel it in my gut. So I uploaded the student’s text to ChatGPT and asked “did you write this?” and it confirmed that it had written it. I even uploaded it to one of those AI checkers, and it gave me a score of 83% AI generated. I confronted the student, but they deny having used ChatGPT or any other AI at all. What can I do? I don’t want to escalate this if I am not 100% sure.

A master student wants to use AI to generate an image in their thesis. The publisher of the original image does not respond to attempts to contact them, and the student really wants to use this image and says they need it. The image is a photograph of some structure they are discussing in the thesis through a microscope. I do not think generating and using an AI image is right thing to do. What should I do?
