In doing this exercise, we have confirmed that, although (on the “moderate quiz” page) it does not show individual students names, the names DO appear in the exact same order (alphabetical) as they do under the “people” tab. Our test had the 29th person on the roster for this course and am the only person who has completed the survey thus far. Lo and behold, Student 29 is the one and only person who has taken the survey. So it was fairly simple to match up who had taken the survey, and this violated student anonymity.
Is there any recommendation on how to push a true anonymous survey to all courses which can be submitted to the teacher in each course? It would need to be anonymous and show who completed it in a jumbled order which doesn't match the People tool?
