I've been thinking how I proctor and design exams, and I suspect (from things I hear) that there is much more cheating than I find evidence of. What are the most common ways university students cheat, say in a large lecture math or science class? For instance, some possible ways are:
- looking at other students exams
- sneaking in a cheat sheet
- using a phone/prohibited device in class
- getting help on a bathroom break
- having someone else take the exam for you
- getting a copy of the exam in advance
- modifying an exam after grading and asking for points back
But I don't know if any of these happen often enough that I should do more than I currently do.
Ideally, I'd like an answer with data from some studies on cheating, but I'd welcome extensive ancedotal evidence as well.
