Instant Notifications - Grade Item updates when associated with assessment
In D2L I have noticed that an Updated Grade instant notification is triggered when a grade item is associated with an assignment or discussion, even if the score itself has not changed.
In my test, I had a Quiz, a Discussion, and an Assignment all linked to the grade book with a test student having received a score for all three. The Updated Grade notification was sent to the student when their grade for each item was published (as expected). Then, as an instructor, I removed the grade item association for each of these assessments, the student did not receive any sort of notification from this change. However, when I re-associated each assessment with its corresponding grade item - having changed nothing else - this triggered Updated Grade notifications for the Assignment and the Discussion, but not the Quiz.
Is this expected behavior and if so can someone explain the reasoning behind it?
