We have 2 main systems that allow students to upload work to be assessed – Turnitin or directly via My Dundee (Blackboard). While Turnitin (accessed from My Dundee) remains the preferred option, there are some instances when My Dundee is more suitable. There are a number of reasons for recommending Turnitin generally

  1. The improved similarity checking.
  2. It allows for a larger file size for similarity checking.
  3. It allows for a more consistent approach across the university.

N.B. If you are marking with student names visible, then many of the Blackboard features are also available if you want to use Turnitin for similarity checking.
