1 Technology Enhanced Learning Blackboard Guides A staff guide to viewing the Similarity Report in Turnitin What is a Similarity Report? The similarity report highlights text in a student s paper that matches an online source. Lecturers can choose to generate a similarity report when a student submits their assignment through Turnitin in Blackboard. Why make use of Similarity Reports? A similarity report can support tutors in the deterrence or detection of plagiarism and collusion to help maintain the academic integrity of work. The similarity report can be used as a formative learning tool to assist students in understanding and avoiding plagiarism. It is possible to allow students to see the similarity report produced on their submitted work. How to do it When is a Similarity Report produced? The choice to generate a report is made when a New Assignment submission is set up. You will need to choose Optional Settings and select Yes under the heading Generate Similarity Reports for submissions? to enable this feature. Allowing students to see their Similarity Reports Choose the following settings when creating a New Assignment, select the Yes box under Allow students to see the Similarity Reports?. And then under the drop down menu beside Generate Similarity Reports for submissions choose either: Immediately first report is final, if you want students to see a report before the Due Date but not be able to submit further work. Immediately (can overwrite reports until due date), if you want students to be able to see their report before to the Due Date. They can then re-draft their work in response to the content of the report and re-submit. On due date, if you only want students to see their report after the hand-in deadline for reference.
