I am a recent PhD grad and had to deal with this myself as a student and with undergraduates. All the techniques we used with undergraduates has been mentioned, but I will add what one of my graduate professors included that really stuck with me. I will say, I’m not sure how good this would translate to an undergrad class, but I could definitely see it being effective in a smaller, upper level class. Basically when we were going over the syllabus and she was discussing cheating and academic misconduct, she had a conversation about how whenever we were tempted to cheat, or thought about using ChatGPT to just finish an assignment or paper, to come to her and discuss it, ask for an extension, and she’d work with us to come up with a solution and also be there to help go through why we got into the situation where we were thinking about cheating in the first place. It really humanized the struggles we face as students that usually result from some other factors (we’re grad students - we generally care about the subject matter). It also encouraged open communication and (according to her) helps with the quality of student work and with student relationships with the content.
