There has been a lot of confusion about using Blackboard's new Student Preview. This short video should help to clear up some of that as I explain how to use this tool to create a test submission.
NOTE: This test submission refers strictly to the version of writing text into the submission box. However, it would work the same if you were to upload a file, except that you wouldn't click on the 'Write Text' button. You would choose the file upload instead.
NOTE 2: I'm afraid the title is incorrect, as it says, 'Student Rubric Tool'. The correct title would be 'Student Preview Tool', as the narrative states. Apologies.
