Specifically, I currently use Speedgrader to comment on, and rubrics to score, essays submitted. I also link essay rubrics to Learning Outcomes. Turnitin LTI 1.3 says Speedgrader and rubrics will no longer work. That says to me that grading will only take place in Turnitin, which I have never used for that purpose before (I have been using it just as a tool for students prior to final essay submission). I can't find documentation that tells me how grading will be transmitted to Canvas, if I can override an essay grade in Canvas, and if I can still use the Learning Outcomes Gradebook. Any information would be greatly appreciated.
