Here are notes from ITS and COLI administrators that are the result of our investigations or recorded observations about D2L and it's various features. The latest of these have not yet made it into our training videos, but will be included in the next replacement of the appropriate video.
D2L Quiz Submissions - Instructor Setup
The "View Restrictions" date establishes the time after which the quiz submission views will become available to students taking the quiz.
Submission views require the quiz to “allow attempt to be set as graded immediately upon completion” in order to appear to students. If there is no grade, there is no submission view available to students.
If there are multiple attempts allowed, the earlier grade can be replaced by a higher grade, depending on the quiz options set for multiple attempts. (Overall Grade Calculation)
D2L has a minor bug in the "Attempts" selector within quiz submissions. If the Instructor chooses an attempt for a particular submission view, the instructor must also include a min score and max score. This can be Min Score - 0 and Max Score - 100. If these are left empty, the submission view will not function. Min and Max score stipulations are not necessary if the Attempt selector dropdown is left at N/A.
