Plagiarism Detection through Blackboard

Turnitin logo


Turnitin identifies overlap between pieces of writing and produces an originality report as well as a tool for peer review and a tool to facilitate online marking of student papers. The following features are included with Turnitin:

Originality Check
When a paper is submitted to Turnitin, it is compared against three large databases of content from three primary sources:

  • The Current and Archived Web: Turnitin currently contains over 40 billion web pages from the current web as well as archived web pages.
  • Student Papers: Turnitin compares submitted papers to a database of over 300 million papers in the Turnitin paper database.
  • Content Partnerships: Turnitin has partnered with leading content publishers, including library databases, text-book publishers, digital reference collections, subscription-based publications, homework helper sites and books. These partnerships have contributed over 110 million additional articles to our databases.

Instructors using GradeMark are able to provide students with rich feedback. With this feature not only are they able to overlay the OriginalityCheck but they are able to quickly add standard or custom marks and comments directly on the paper. Additionally with the Rubrics tool they are able to convey clear expectations and speed up the grading process.

The PeerMark feature within Turnitin facilitates peer review so that students are able to easily evaluate each other’s work.

Turnitin for iPad
Originality Report, QuickMark comments, voice comments, custom text comments, and highlights—everything you need to provide effective feedback on student writing is available on the iPad. Instructors are also able to sync assignments to their iPad so they can grade them on- or off-line.

About Originality Check
Papers submitted to Turnitin may be compared against billions of internet documents, archived internet data that is no longer available on the live web, a local repository of previously submitted papers, and subscription repository of periodicals, journals and publications. The comparison may be against any or all of these repositories as set on a specific assignment by the instructor of the class.
