This is a sad topic to write about. It is a great waste of time and energy for instructors to have to deal with things that should not happen. Reflect on the number of hours and days you have spent on cases. We actually think that upon proof of the crime, the student should have a financial penalty as well, to cover the true cost of their actions to the institution. Time and material. Including opportunity cost. We have ALWAYS had better things to do with our time than deal with a student who crossed the line. The time and effort to deal with cases is usually over and above planned activities and other obligations are not reduced. For example, if 25% of the class is invovled in academic integrity cases, there is a significant effort to deal with all of the cases and this can take time away from other obligations. Does anyone care about this during the yearly merit review?
We will not repeat here the litany of reasons why academic integrity is important. If you do not think that cheating is an important topic, and must be dealt with in a serious, consistent fashion, beyond the 'I am sorry, I will not do it again' sing-song, you should probably go talk to the Dean.
However, we will repeat one or two points. A student cheating impacts the other students in many ways. A student cheating impacts the program as well. The impact is not limited to the student cheating. There is the whole honesty and integrity thing, but if that is not enough to motivate instructors, the reduced currency associated with the course and program might.
