Submission folders in to D2L can be set with Originality Check® from Turnitin. When enabled, Turnitin will check all submitted files for matches in a database of Internet sources, academic journals and publications, and student papers. Turnitin works for the following document types: MS Word, WordPerfect, PostScript, PDF, HTML, RTF, and plain text.
Instructors can use Turnitin outside of a Submission folder by requesting an external account. To request an external account, use the External Turnitin Account request form.
For information on Turnitin's AI detector, see AI in Higher Education.
If an assignment requires students to use a template with text, instructors can upload the template document so Turnitin will not review this text during the Originality Check.
Originality reports can take time to generate after a file has been submitted to Turnitin. Usually it only takes a few minutes, but sometimes it can take up to 24 hours.
If a report indicates that a submitted file matches another submitted file in Turnitin's database,
contact the CTL to obtain a copy of the file.
To begin providing feedback to and evaluating student submissions within D2L, see Annotating Submissions and
Evaluating All Files Submitted to a Submission Folder.
