Today's Gratitude Item: Being able to easily prove that some of my students cheated. Obviously I'm really, really annoyed that they did not do the work themselves but at least in computing it is very easy to prove cheating when it happens. I have all the evidence on my computer and come next week there are going to be a number of very upset students (and parents) at school.
