There are two main different types of Course Menu items: a Content Area, and a Tool Link.
A Content Area Course Menu item can be used to add text, images, audio and video to your course. You can also include assignments and tests for students to complete in Blackboard.
A Tool Link on a Course Menu takes students to one of Blackboard's specific tools that you have chosen to utilize in your course. Examples of Tool Links include: Discussion Board, Blogs, Journals, or My Grades.
