The article does say that math and science classes inspire the most incidents which obviously interests me. Whenever I require a paper now, I require students to submit it to Turnitin first to check for plagiarism - students still try to get away with it, just a couple of weeks ago a student handed in a paper with over 50% directly-copied content (no quotations, no citations).
I'm not naive, I know students cheat and plagiarize each other on assignments and labs. I encourage students to work together, but some take that to mean they can copy off their classmates. I generally know who's doing it (although I can't always prove it) and I always announce to the class that they're not going to be able to work together on the lab exam. And, predictably, a certain number of people fail the lab exam (the same ones I suspect are copying on labs all semester). Since the lab exam is worth a lot more than individual labs, they're only hurting themselves in the end.
I really do hate having to treat all students as potential cheaters. I'd rather be grading or reading something while students are taking exams instead of pacing around watching them like hawks. Unfortunately, past experience has shown that some people do try to cheat and that's not fair to the honest students.
I also surf the web looking at web sites on how to cheat. I'm wise to many of the tricks used!
