Ron,
You are absolutely right in your interpretation of my poorly described grade book.
I have 5 assignment groups, 1) case studies (total of 5), 2) exams (total of 5), 3) Quizzes (total of 10), 4) attendance (just a single item), and 5) extra credit (currently no weight), weighted 15%, 65%, 15%, and 5% respectively. We are in the middle of the semester, so I have not opened all of this yet. I am assuming Canvas is NOT counting the unpublished assignments for the calculation of the assignment group total, which would be ideal to show progress to students, but I would appreciate clarification on this from this community. Also, I have a rule set up for the two lowest grades in each category to be dropped. For the case studies, this would explain why I'm seeing Canvas getting the highest grade only, because we have only done 3 case studies so far, so if the student has 80-80-100, the 80s would be dropped and Canvas would keep the 100% as the grade for that category. But this is happening also in the quizzes group, where we have done 5 so far. The rule is the same, 2 lowest grades are dropped, but then if a student has 80-80-80-80-100, Canvas is giving them 100% instead of the average of 80-80-100 (after dropping two 80s), which would be 86.6%. As you probably understand, this may create BIG problems in the long run when I adjust these and students see their grades drop...
While I figure this out, it would be very helpful to hide the totals for each assignment group in the grade book, but our local support said we cannot do that either. I would have to hide the grade of one individual assignment for the group total to be hidden, which obviously does not work for me or my students.
Thank you so much for taking the time to help me!
Inma.
