The group assignment feature cannot be used with a Turnitin LTI assignment in Canvas, but there are other ways to support group submissions in Canvas.
Once students have already taken a graded quiz, any changes that affect the quiz score such as deleting questions or answers, or manually entering a new mark typically do not work.
Turnitin rubrics can be attached to Turnitin (LTI) assignments. Qualitative rubrics provide feedback only. You cannot apply the rubrics as grades for the students’ submitted works.
By default, all Turnitin submissions are added to the standard paper repository and checked against three sources for the Originality Report. You can choose different options for the assignment via Canvas.
If you are using a program outside of Canvas, such as Remark or TeamMates you can bring the exported marks from these programs into Canvas.
Create a ‘no submission’ assignment instead of a quiz.
