The thing that bugs me enormously about this scandal is that Harvard has several times (I think) turned a blind or at least extremely lenient eye toward plagiarism among their faculty.
Oh lord, it was a take-home final and the prof expected them NOT to talk to each other about it? That's ridiculous. If you don't want students to talk to each other, then make them do it in the classroom like a normal exam. Harvard is acting all surprised like every angel of a student goes home with their take-home exams and locks themselves in their room and doesn't emerge until it's complete.
I'm glad we're all patting ourselves on the back for being more honest than a bunch of Harvard students, but those of us who have access to Harvard Q know that the professor in question is actually notorious for giving impossible final exams that often ask about material that wasn't covered in class. The story on campus is that students had been flocking to the department tutors for help and had complained to the department about the final before it was due. I guarantee you that this story is going to blow over pretty quickly with nobody getting punished for this within the week.
Doesn't surprise me. People openly cheat on the test to get food handler's cards, and they make you go through a "class" where they hold your hand through all the answers beforehand.
My experience teaching undergrads is that when half the class fucks up, there is usually something wrong with the exam or with course communication. I'm not so quick therefore to assume all these kids knowingly cheated. Was the policy on non discussion made crystal clear? How did TAs communicate with students during the exam time? What other resources were allowed? Could the exam be completed in the allotted time with the permitted resources? I bet you there is more to the story than simple cheating.
