The more students use technology to do homework, the more they cheat:

In surveys, he asked students if they viewed bringing a cheat sheet to an exam as cheating. Most did. Then he asked the same students whether they would consider it cheating to bring a graphing calculator with equations secretly stored on it. Many said no, that wasn’t cheating.

“I call it ‘technological detachment phenomenon,'” he told me recently. “As long as there’s some technology between me and the action, then I’m not culpable for the action.” By that logic, if someone else posted homework solutions online, what’s wrong with downloading them?

One proposal:

Make it easier for professors to handle such cases, and reform academic judicial systems to make clearer distinctions between smaller violations, like homework copying, and larger ones, like cheating on exams. And assign appropriate punishments for each.

What stops students from cheating?  Social norms must play some role.  Formalizing a price for allowing a decision maker to violate a norm might invalidate the norm and cause its collapse.  This is the idea in an experimental paper by Gneezy and Rustichini “A Fine is a Price”.  If the norm collapses, cheating may actually rise if the fine is too small.  So the appropriate punishment for  small infringement is large – then, even if the norm collapses, the fine alone will deter cheating on homework.  Maybe a large fine for small infringements is not credible.  How could a professor or a university justify a large fine for a small crime morally or even worse to an angry parent? If that is a problem, the present system, turning a blind eye to small violations, might be the best system after all.
