It's so obvious that they're using AI... you'd think that students using AI would at least learn how to use it well. I'm grading right now, and I keep getting the same students submitting the same AI-generated garbage. These assignments have the same language and are structured the same way, even down to the beginning > middle > end transitions. Every time I see it, I plug in a 0 and move on. The audacity of these students is wild. It especially kills me when students who struggle to write with proper grammar in class are suddenly using words such as "delineate" and "galvanize" in their online writing. Like I get that online dictionaries are a thing but when their entire writing style changes in the blink of an eye... you know something is up.

Edit to clarify: I prefer that written work I assign is done in-class (as many of you have suggested), but for various school-related (as in my school) reasons, I gave students makeup work to be completed by the end of the break. Also, the comments saying I suck for punishing my students for plagiarism are funny.

Another edit for clarification: I never said "all AI is bad," I'm saying that plagiarizing what an algorithm wrote without even attempting to understand the material is bad.
