I was a Head of English in the days before AI was in the picture, but cheating on coursework still existed and the same sort of consequences exist for using AI as paying someone to write your essay or buying answers online or getting your parents to write it or just copying something you’ve found. I’ve had all of those happen with GCSE coursework.
The student may get away with it for a while but not forever. It’s easy to fool one teacher here or there, but further into the course there will be moderation when more than one teacher is looking at the student’s work. If one person queries it (and this is likely, as some people are easily fooled by AI and others just aren’t!) then the work submitted will be compared to exercise books from classes, possibly multiple subjects. Either the quality will be very different, and the coursework will be disallowed, or the quality will be similar and then it’s daft that the student even tried to cheat. Those students are still usually caught out in the end because something will give it away (usually that the cheat answer doesn’t jive with something the teacher specifically pushed in class).
Once a student is caught, if it is for coursework, there’s a whole series of knock on actions. We would then inform all subjects in the school of this incident and bring all the coursework from all subjects into question. In fact we had one HOD in Humanities who had a blanket policy of disallowing all coursework if you were caught cheating in another subject, and the student would have to come in before/after school and complete an entire folder of new coursework in her classroom so they could be monitored.
I’ve also had to inform exam boards of known persistent plagiarists so their folders across multiple subjects could be moderated by staff outside the school.
I didn’t teach in a fancy school (in fact the opposite, quite a rough comprehensive) so it’s not just schools with an excellent reputation that can be quite serious about this. Could a student get lucky and their school doesn’t do much? Sure. But it’s a lot to risk. I remember a student getting caught quite late in the game and when all the other y11s were off doing fun stuff, he was spending all his hours in the school, redoing everything in hopes he would pass at all. He was moved from higher to foundation papers so couldn’t achieve his predicted grades and had to change his A Level plans. He was barred from the leavers’ prom. It can all be an absolute mess. I think he cheated more and more because he got away with it once and started to feel invincible, so he did less and less actual study as the time passed.
I guess I would impress that there’s a domino effect to come, one line leading to all the trouble and having to rework everything or possibly being entirely withdrawn, and the second line leading to being completely unprepared in the exam when it’s just the student and a desk and no AI to help at all. The odds are just not in her favour!
