Detecting similarity matches for consecutive student submissions in the same subject
It has been noted that if a student resubmits their paper from a previous assignment to a subsequent assignment in the same subject, Turnitin does not generate a similarity report based on their previous submission and will automatically exclude it.
Instructors need to click on the similarly score of students in the speed grader (If they are using Turnitin plagiarism Framework) and open the Feedback studio. In Turnitin LTI, instructors can click on the view similarity matches or Instructor feedback within the assignment itself.
