TAed last semester and I caught about 8 students for cheating, all time high out of 6 semesters (never really caught anyone before). All of it is pretty unsophisticated since I don't think we even could police sophisticated methods that well, you know the legendary printing the exam notes on the coca cola label and other high effort methods. Most of them were actually
whispering to eachother in exam or otherwise blatantly staring at answers from another student, in a room with 4 proctors. Another case for an essay sort of assignment we saw straight up copy and paste of entire paragraphs from another student in their class, and for another case from past materials. I don't know how they thought they could get away with any of this. Both of these students emailed actually surprised they failed the assignment....
Really our detectors don't check AI use at all. You can probably chatgbt it all and I couldn't really tell. However, they check if this sentence matches with a sentence either out there on the internet in the primary sources or, most often, from another students submitted assignment from our or a partner university using the same saas. And people are getting caught and having their college career ruined just from that, straight up copying and pasting with no paraphrasing even and thinking we won't notice that.
They must have gotten away with highway robbery in highschool during the COVID years. Employers will have to look at this COVID generation with a big side eye and put more emphasis on in person tests of knowledge. Maybe they should use the various testing centers used for MCAT/GRE/LSAT/etc for these remote interviews where they provide a locked down desktop and have cameras surveilling the room.
