A question on the academic integrity side: I know that some UBC stats questions have breadcrumbs in their datasets, so that when a question is posted online, it can be traced back to a particular student.
Has anyone thought about how to do this in something like a standard Calculus problem?
(E.g. if I see a question on a site like Chegg, and a particular set of values are present for random variables, could they be traced? Not with standard problems, I think. Is there something we could add that wouldn't be an obvious attempt to make the question traceable?)
Context: a colleague (who is also my wife, so I have extra motivation in this case) is currently teaching Calculus 1 online, in summer session.
She's using WeBWorK, and made it clear to students that the homework was for practice, and provided the following conditions:
- It's only worth 3%.
- They can work in groups.
- She will walk them through the solution (with different numbers) in either a Zoom meeting or the discussion forum.
So there should be really low incentive to cheat. And yet, those WeBWorK problems are already up on Chegg. (And not all the students are dumb enough to leave their user ID in the screenshot.)
