Student Fights University Over Plagiarism-Detector

(Maly) writes "CBC is reporting that MCGill University has lost a fight to have students first turn papers over to an anti-cheating website before handing them in to professors. The student refused to hand in three assignments to the service, received a zero on those assignments, then fought the ruling. The story doesn't have many specifics, such as the venue of the fight (court or some internal university tribunal), but it is an interesting case. As a recent graduate of the social sciences, I find that practice appalling. The student is right to refuse, as he gets no compensation from the service for making money off his original work (assuming it was original!!). Although I don't like the idea, and I'm glad I never went through it, I suppose its analogue would be mandatory drug tests in sports."

    I have two takes on this story. First, I do find it a bit offensive to presume cheating on the part of students and to require them to "prove" they didn't cheat rather than the burden of proof running the other way. I do believe that if you expect certain behavior from people and let them know your expectations, then they are more likely to confirm them. This is the same reason that I find the anti-cheating posters in our classrooms at Wright State University offensive -- students know they aren't supposed to cheat, so the posters just create the impression that it's a pervasive part of the academic experience.

    Second, that little quip about financial compensation is completely off-base. Students pay to learn, and once the prof has decided that they'll have a better learning experience if they submit to the site (presumably because they will feel forced to think for themselves instead of copying from term paper mills) they have no "right" to compensation. The practice is offensive, but from an educational standpoint, it is little different than the professor using their papers in class as examples for others. Either way, other people benefit from the student's work without compensation for the student. That's the way education works. The fact that antiplagiarism sites make money from their line of business (and the examples submitted by the students) is of no import, as long as they aren't selling the essays as part of an anthology or something. It's a feedback loop within the educational process and even though I disapprove of the practice, nobody's "rights" are violated.

    What you did was not plagarism, but it probably was against policy. It surprises me that there was no name attached to the original work. I suppose you could do something like officially copyright your work as you turn it in, so that there's no question that you wrote it.

    If your H.S. teacher turned it in without your permission, it may have been a violation of copyright law. You could actually sue to get the paper removed from the database (although since you submitted it in college, and presumably agreed that it would be turned in to the service, it would probably be replaced in the database).
