I have two sections of one class and decided to cross list them after having started them independently. Upon cross-listing, the scores from the child course are no longer appearing in grades. That is, it appears as if they didn't complete the assignments/quizzes. Is there a way for me to retrieve this information? Going forward will it report all scores?
Cross-listing should be done while courses are unpublished. Coursework is retained with the course, not with the section enrollments, so if a published course is cross-listed, all cross-listed enrollments will lose any associated assignment submissions and grades.
,,,and it sounds like that's exactly what happened in your case. I recommend that you submit a help ticket to Canvas Support to see if they can retrieve the lost scores. Since cross-listing active courses is not recommended, I can't say for sure whether all scores will be reported for all students in the newly cross-listed entity; it should, but those waters are officially uncharted. Perhaps Support will be able to determine that as well.
If you de-cross-list those sections, all the scores will come back. Of course, they'll be back in the original shell. So if you want to keep them cross-listed, you'll have to note the scores, re-cross-list, and manually add the child scores into the parent shell.
Any work done after the cross-listing will show up in the gradebook.
Where you able to find an answer to your question? I am going to go ahead and mark this question as answered because there hasn't been any more activity in a while so I assume that you have the information that you need. If you still have a question about this or if you have information that you would like to share with the community, by all means, please do come back and leave a comment.
What I found out after encountering the same thing was to re-assign your assignments and quizzes back to the Section you Cross-listed. Your scores should reappear with the original scores. Hope that helps for some one who comes across this same encounter.
