Shells allow you to develop your course materials by adding content, creating activities, and building assessments well in advance for upcoming courses. Shells also allow faculty to retain course materials in Blackboard after Courses are deleted (generally after 13 months). Shells can not be made available to students, and student enrollments are not added to Shells. If a Shell is made available, it will revert to being unavailable the next day.
When you are ready to teach the course, you can request the Blackboard Course and copy your materials from the Shell to the Course.
