Using Student Preview Mode
The Student Preview feature allows instructors to view their course from the student's perspective. You want to be confident that your course is well-designed and functions as you expect—before your students see it. You can also validate course behaviour. For example, you can review the Release Conditions of content and how grades appear.
About PreviewUser
When you enable student preview, your preview user is visible to all participants. For example, the user appears in the roster.
If you teach a course with another instructor, you each can have a preview user account.
As a preview user, all your activities are captured by Blackboard Learn. Other students can interact with your preview user, however your preview user activity isn't included in analytics and course reports.
Groups: Do not add a preview user to a group with other students. If the preview user submits a group assignment as the preview user and they are later deleted, you may not be able to access the group submission. If you create self-enroll course groups, your preview user is enrolled automatically at the end of the optional enrollment period.
Discussions: If you post to the discussion forum with your preview user, other students can reply. When you remove the PreviewUser from your course, the post remains but “Anonymous” appears as your preview user’s name.
Kaltura media: Any media created and uploaded to Kaltura in Student Preview mode will be stored in a separate My Media [Your Name]_PreviewUser account. To access this content, it would be necessary to use My Media in a course while in the Student Preview mode.
You can't use Student Preview or make other changes in a Completed course.
