Reply #3: about the presumption of guilt -

[noamnety]

the presumption is not that you as an individual will cheat, but that odds are someone in the class will.

Unfortunately that's been my experience. When I was working on my masters in education I had (stupid) team projects to work on. This was with people about to get certified as teachers. I started running our own group papers through turn it in, and twice people in my own group plagiarized sections of papers my name was going on. I guess even the future teachers didn't have enough integrity to give a shit about potentially screwing me over and getting me kicked out of a program.

When I went to get fingerprinted for my certification, in the lobby of the police station two cops were laughing about plagiarizing papers for a college class they were taking.

When my husband recently was evaluating proposals for bids for an army contract, he saw that one of the contractors had the nerve to plagiarize a technical paper my husband cowrote!

My experience: cheating is completely out of control, beyond what you could imagine. A teacher would have to be a fool to presume that everyone in their classroom valued integrity.
