17 Checking for plagiarism in assignments submitted through Canvas

IU has a contract with Turnitin that allows instructors to use the tool to check student work within Canvas. For more on using Turnitin, see the Best practices for teaching with Turnitin in the IU Knowledge Base. Note that you cannot use Turnitin to compare two papers side-by-side. If you would like to check for the same text in two different Word docs, use the MS Word “Compare” function. Instructions are available at Compare document differences using the legal blackline option on the Microsoft website.

There are two ways to use Turnitin with Canvas: using the TII integration with your regular Canvas assignment or having students submit directly to TII using Turnitin’s Feedback Studio tool.  The differences between the two options are detailed in the table below. If you are interested in learning more about TII Feedback Studio, see the “Learn more” links in Use the Turnitin external LTI tool in Canvas in the IU Knowledge Base.

Creating an assignment using the Turnitin Canvas integration

To create a Canvas assignment using Turnitin

  1. Create a new assignment or click the “Edit” button on an existing assignment.
  2. Scroll down to the “Submission Type” setting and choose “Online | File Upload.”
  3. Scroll down to the “Plagiarism Review” setting and select “Turnitin” from the drop-down menu.
  4. Choose which repositories you would like the paper to be checked against (articles, websites, and other student papers)
  5. Choose what you would like excluded (references, text in quotation marks, or small sources (i.e. 2-3 words))
  6. If you would like students to see the Similarity Report, be able to correct errors, and resubmit before the due date, make sure the Submission Attempts setting is set to more than one Show report to students is set to “Immediately” (Note that it’s not always immediately as it can take a few minutes to process. How long depends on the size of the paper and how busy their system is.)
  7. Save the assignment.

Checking a single paper

If you would like to see the Similarity Report on a particular submission but did not have Turnitin enabled on the assignment, you can submit the paper in Student View and see the report without requiring the student to resubmit. There are a couple of ways to do this. You can either use an existing Canvas assignment or creating a generic assignment in a practice course.

Using an existing assignment

  1. If you already have an assignment set up with Turnitin, even if it’s in a different course, you can use it to check any paper.
  2. If you don’t have any assignments set up with Turnitin, you can edit the assignment in question to use Turnitin by following the instructions above.

If you use either of these methods, make sure to remove any past “Available Until” date set on the assignment. You will not be able to submit a paper in Student View if the Available Until date has passed. Once you have submitted the paper in question you can re-add the Available Until date. 

Creating a reusable generic assignment in a practice course

Alternatively, if you regularly need to check individual papers that are not always associated with a particular class, the easiest thing to do is to have a Canvas practice course site with a generic assignment that you can re-use to check papers across multiple assignments, classes, and semesters.  If you don’t already have a practice course site, the IU Knowledge Base provides instructions for creating a Canvas course site that you can use for this purpose. Follow the instructions above to create the assignment and make sure to set it to have unlimited submissions to be able to resubmit additional papers at a later date.

Checking a single paper in Student View

Once you have an assignment set up, to check an individual paper:

  • Go to the assignment and click the Student View button at the top right of the page. (Don’t click the edit button. You will not see the Student View button when editing the assignment.)
  • Submit the paper.
  • Click the “Exit Student View” button at the bottom right of the page in the pink bar.
  • Wait a few minutes.
  • Click on the Speedgrader button, navigate to Test Student at the bottom of the student list dropdown, and check for the Similarity Report.
To download a pre-formatted template for a Turnitin Assignment where students see the Similarity Report and can revise and resubmit, go to Canvas Commons by clicking the Commons icon () in the red navigation bar on the left of any Canvas page and search for “Turnitin report assignment template.”
