I could try to put together some kind of blog for today (and rest assured, good reader, that a blog post is brewing), but Mick Beltz has already put together a far more interesting blog post than I could muster. He responds to recent discussions of cheating at the University of Central Florida, and without getting into detail, sets out three basic lessons to keep in mind while preparing your end of the semester exams:
1. There is an optimal level of cheating on every assignment (and it isn't zero).
2. Grades and assignments have only instrumental value, not inherent value.
3. Cheating is not (just) a student problem, it is also an instructor problem.
The post is really smart, thoughtful, and thought provoking. In fact, it's so good, I'm going to link to it again.
