I wish more teachers and academics would do this, because I"m seeing too many cases of "That one student I pegged as not so bright because my class is in the morning and they're a night person, has just turned in competent work. They've gotta be using ChatGPT, time to report them for plagurism. So glad that we expell more cheaters than ever!" and similar stories.
Even heard of a guy who proved he wasn't cheating, but was still reported anyway simply because the teacher didn't want to look "foolish" for making the accusation in the first place.
Something I saw from the link someone provided to the thread, that seemed like a good point to bring up, is that any student using a screen reader, like someone visually impaired, might get caught up in that as well. Or for that matter, any student that happens to highlight the instructions, sees the hidden text, and doesnt realize why they are hidden and just thinks its some kind of mistake or something. Though I guess those students might appear slightly different if this person has no relevant papers to actually cite, and they go to the professor asking about it.
My college workflow was to copy the prompt and then "paste without formatting" in Word and leave that copy of the prompt at the top while I worked, I would absolutely have fallen for this. :P
Is it invisible to accessibility options as well? Like if I need a computer to tell me what the assignment is, will it tell me to do the thing that will make you think I cheated?
