I’m a UK teacher. I have built a custom GPT that marks essays for the subject I teach in a repeatable and reliable way. It gives actionable feedback to students.
I use it, and have given my students access to it too - they use it to help their revision.
Kids making mud cakes, climbing trees, and taking shots at each other with shanghais. Teachers lounging on a beach somewhere. Meanwhile in classrooms, bots.
How about critiquing? Like, the moral equivalent of an editor pointing out issues and/or suggesting alterations? I think it would still be the student doing all the things you pointed out, but I suspect there's a fair amount of leeway in the interpretation of each of those.
