I gave my students a take home exam over spring break. (This is normal where I teach) One of the questions was particulary difficult. It came down to a factor of three in the solution. That factor inexplicably appeared with no justification on many of their exams. I intend to have the students I suspect of cheating come to my office to solve the problem on the board. What would you do?
I’ll take your word for it. At the institution I’m currently at and my former one this is academic misconduct as it isn’t your own work. I’m real suss on anyone claiming to have a phd while suggesting methods that essentially introduce a potential time bomb for your degree. May as well actually learn how to learn if you’re going to uni but hey that’s just my (apparently red hot) take.
