Dropbox – Create an Assignment with Anonymous Submissions
To avoid unconscious bias in the grading and feedback process, instructors can configure Dropbox assignments to use anonymous learner names.
Note: At this time, the Anonymous Marking option (Hide student names during assessment) is only available upon request. Please contact the IT Support Centre, provide details of your course and a system administrator will be able to turn on the tool for you.
