Is there evidence that using Turnitin actually reduces student plagiarism?

According to Turnitin:

A statistical analysis of 7 years of data from high school and college submissions to Turnitin found that after two years of Turnitin use, serious instances of unoriginal content and plagiarism in student writing decreased by 20 percent or more. After four years, institutions experience improvements of 35 – 70 percent.  Read more…

Creating Revision Assignments

If an instructor would like students to submit multiple drafts of an assignment without overwriting previous drafts, s/he could a) manually go through the process of creating new, separate Turnitin Paper Assignments or b) they could use the Revision Assignment option.  In short, a Revision Assignment simply copies settings from an existing assignment thereby reducing the time spent in setting up the assignment.  Instructors still have the option to modify Revision Assignment standard and advanced settings, if desired.

To create a Revision Assignment:

  1. Log into your course site with Edit Mode set On.
  2. Click on the content area (i.e. Content, Course Documents, Information) where you would like the link to the assignment to appear.
  3. Click Assessments > Turnitin Assignment.
  4. Select Revision Assignment and click Next Step.
  5. Select the assignment this revision should be based on.
    Enter the point value for this revision assignment.  Please note:  Point values must be whole numbers.  Turnitin does not accept decimals.
    Select the corresponding Start, Due, and Post Dates.
    Enter any special instructions, if applicable.
  6. Make your Originality Report selections, and click Submit.

Creating a PeerMark Assignment

PeerMark is a tool that allows students to provide feedback on each other’s papers.  Before this tool may be used, however, an instructor must first create a Turnitin Paper Assignment to which students submit their individual work.  Once that is in place, then the instructor can elect to create a PeerMark Assignment that pulls documents from the original Turnitin Paper Assignment pool of papers to be distributed to and assessed by students.  For step-by-step instructions about how to create a PeerMark Assignment, please see page 12 in the Turnitin Blackboard Learn Integration Manual.
