People often ask me if the attitudes and quality of the work of college/uni students have changed over the 20+ years I have been teaching. Yes, they have, and none for the the better.
However, on another issue, I have had twice as much plagiarism in the last year than I have had in the preceding 20 years.
And try to fool me once with plagiarism and get caught, shame on you. Try to fool me twice with plagiarism and get caught, you are just an idiot.
