The line between collaboration and cheating is fuzzy. It’s still clear at the edges, but messy in the middle. When students are working in groups, searching for a solution to a problem, looking through possible answers for the best one, or sorting out material to include in a presentation, that’s collaboration. When one student in the group solves the problem and everyone else copies the answer, that’s cheating. When one student fails to deliver material she or he’s been assigned and the rest of the group covers, that’s cheating.
