Good morning,
I've hit this issue a few times and it is a bug in the canvas system that can be replicated.
This only really occurs, if like me, you cannot use or choose not to use differentiated assignments.
Specifically if using the Turnitin LTI (not CPF), multiple differentiation does not work.
In the example we have a number of resubmissions that occur within a weighted group
The original assignment at the top is open to everyone to submit, the additional assignment slot is created if a student cannot meet the original dead line date or get a chance to resubmit after the first assignment does not pass.
When a tutor is marking the assignments it is likely that to indicate the original submission will be updated to 0% to show other markers this has been reviewed and marked at 0%
For example
Two assignment groups both weighted at 50%, each assignment is marked out of 100.
Assignment 1 the student does not have any problems with this assignment, a grade is entered of 57% for that student.
Assignment 2 the student has some problems and has to submit twice.
- The first submitted assignment is scored 0% for first submission to show it failed and to tell other markers it has been graded.
- The second assignment in that weighted group is then graded 57%
Assignment 1 = 57%
Assignment 2 = 57%
The overall course grade should be 57%?
(0.57 x 0.5) = 0.285
+ (0.57 x 0.5) = 0.285
= 0.57 or 57%
However if 0% is entered into the first submission slot for Assignment 2 then then calculation changes and becomes this:
42.75%
This is what seems to be happening
57 / 200 (the 200 is the total marks possible for that assignment group) = 0.285 then it applies the weighting even though a 0% grade was entered in one of these assignments.
(0.285 x 0.5) = 0.1425
+ (0.57 x 0.5) = 0.285
=0.4275
or 42.75%
Not sure if this is a new problem but suggestions to address it would be welcome
