Turnitin Similarity Score update

Starting in March, bibliographic material will be excluded from an Originality Report and Turnitin will recalculate the Similarity Score based on the remaining content only. This change will provide a more accurate score.

For all open assignments, reports will automatically regenerate to reflect this change. You are advised to log in and check the regenerated reports, as this change may cause a slight increase to a paper’s Similarity Score.

Turnitin is an online text-matching service and grading tool, integrated into Blackboard, which supports a fully online e-Submission and e-Grading process for assessments of any file type.

  • OriginalityCheck provides text-matching functionality that can be used to support academic integrity and address plagiarism.
  • GradeMark enables instructors to grade student papers online by evaluating against qualitative or quantitative rubrics and adding comments and feedback.
  • PeerMark is a peer review tool that enables instructors to create assignments that allow students to read, review, and evaluate papers submitted by their classmates.

RMIT’s approach to the use of Turnitin is one of promoting academic integrity in an educative context. This is achieved by using OriginalityCheck in conjunction with supporting practices and attitudes, such as correct referencing and citation styles, copyright management, and information literacy. This approach is supported by the University’s Guidelines for using Turnitin.

OriginalityCheck allows for any submitted text-based assignments to be compared for originality against previous text submissions and other database content (webpages, online e-journals, etc). A report is generated identifying similarities between the submission and pre-existing material, allowing instructors and students to review the attribution and paraphrasing used throughout the assignment to see if any improvements are needed.

Assignments of any file type can be submitted using a Turnitin Assignment within Blackboard, all of which can be graded online using GradeMark. Instructors can add comments within the body of the paper, highlight grammar and punctuation mistakes, evaluate the paper against qualitative or quantitative rubrics, assess the student’s performance within the class, and enter a grade for the assignment that is automatically saved into Blackboard GradeCentre. GradeMark also allows the instructor to record audio feedback on the assignment.
