We (professors + TAs) are reporting a few students for cheating on their midterms to the head of undergraduate studies. We had been monitoring their activities pretty closely, since we noticed they had been cheating throughout the semester on their weekly quizzes but felt that evidence was not compelling enough (e.g., 15 minutes, few questions). But with their recent cheating activity on an hour-long exam, we are confident in what we are reporting to the University.
In the event that they are allowed back into lectures for the remainder of this semester, how do we interact with these cheating students? Should we ignore them? I expect there to be some friction between them and us, and I wish to not be too distracted from teaching the rest of the class of students that have been working diligently and honestly.
