For assignments using the plagiarism framework (we use Turnitin), the originality report is available via a link next to the submitted file in SpeedGrader. When you click on the tag icon (with the originality score) next to the file name, the Turnitin originality report opens in a new tab.
This functionality is not available in SpeedGrader on the Canvas Teacher app. The tag and originality score is displayed, but it's not an active link. Though the similarity score is displayed in SpeedGrader on the Canvas Teacher app, there is not a way to access the originality report. I would need to go to a web browser and navigate to SpeedGrader for that assignment in order to access the originality report.
Feature Idea: Make the similarity score an active link in SpeedGrader on the Canvas Teacher app so that teachers can access/open the originality report on a mobile device. This would increase the parity of SpeedGrader on the app with the web browser version of SpeedGrader.
