My brother’s girlfriend is correcting papers now. One kid already plagiarized on a takehome midterm. She just found a student who paraphrased (barely) one of the assigned reading books without of footnote. She didn’t even have the book with her and recognized it. Got the ebook version to doublecheck and yup, there it was. I don’t know why students are so stupid, but they are. (This is Columbia by the way.)
She’d probably have let it go with a warning not to do it again if there had been a footnote, but the wording was really barely changed. No question that it was a problem.
