What happened first wasn’t that surprising. What happened later was.
As predicted, the noise and inattentiveness of two classes inspired me to stop talking about the final exam. Instead I passed out an assignment and said “good luck”. Later I helped the students who actually seemed interested in passing.
I also sent three students back and forth between their desks and my desk until they actually completed their homework. (Long story.)
Then, this evening, as I was grading daily journals written by my university students, I realized that one of my students wrote well enough that he could have been an editor for Wikipedia. Actually, given that his “handwritten journal” matched a Wikipedia entry word for word, I suspect he might already be a Wikipedia editor. Or is it adopter?
Either way, all the students are now required to look up the word “plagiarism” and explain what will happen to them if they try that in the USA.
The trap is that I expect most of them to plagiarize the entry, which will lead to a teachable moment.
