Components are the area in a unit that contains your course content; they are represented by an icon in that unit's ribbon. There are five types of content you can add to your course:
Discussion components: This is where you and your students can go to add posts, comments, and responses to a question. Discussions added to an individual unit appear in the course's Discussion Forum. For additional information about discussion components, refer to the Discussion components section. You can also read the Course discussions section of Chapter 7, Facilitating Your Course, for more detailed instructions.
HTML components: This is used to add information to a unit, including text, lists, links, and images. You can import LaTeX code here and insert hand-coded content (or any content that you've programmed using a WYSIWYG editor). For additional information about HTML components, refer to the HTML components section.
