This is a well-written and carefully nuanced learning object. I was impressed at how well the examples capture the common gray areas that students so often struggle with. Great use of a fun tone in the answer desriptions! (Would that we all were the "Chuck Norris of plagiarism tutorial takers"!)
Very clear and clean formatting. It's a nice touch to offer the option to skip back and forth through the tutorial to facilitate discussion of how different examples compare. Also, I was thrilled to see the inclusion of an email form so that students can do this on their own and submit their results to an instructor with evaluation built in!
My only regret? That I didn't discover this tutorial before teaching a class along these very lines last week!
Because the button at the end of the 10th question triggers the results page and email form popup, it's possible for a student to skip some questions and prematurely finish the tutorial. If they're clever, they can close the form, return to the questions they skipped, and retrigger the form, but this isn't obvious. It would be less breakable if the results page and form were triggered by all 10 questions being complete, not by the button at the end of the 10th question being clicked. Not a big problem because most students will just go through the questions linearly. Still, this would be a nice refinement.
