A course in Moodle is an area where you, as an instructor, will add resources and activities for your students to complete. It might be a simple page with downloadable documents or it might be a complex set of tasks where learning progresses through interaction. Progress can be tracked in a number of ways.
The course page is made up of central sections which contain the tasks and (if desired) blocks to the side. The course teacher has control over the layout of the course homepage and can change it at any time.
Students are enrolled in your course automatically Students can also be added to groups if they need to be separated from classes sharing the same course or if tasks need to be differentiated.
Please be advised that general Moodle documentation may contain slight variations from the University's specific version.
