A class represents a specific instance of a course offered during a particular time period. Each class has its own Learning Plans, students, and facilitator(s). Semester - Visible only in Academic Calendar programs, this field specifies the semester during which the class takes place. Grading System - Defines or overrides the default grading system for the class. Note that the grading system cannot be changed once students start completing assignments. TipCloning ClassesWhen the day comes when you must make a new version of an existing class, save time by using the Copy button. This duplicates the class and its learning plan activities but excludes students and facilitators. For always-active (On-Demand) classes, remember to uncheck the Public checkbox on the newly cloned class until it's fully prepared. This prevents enrollment before it's ready. Once the new class is complete, re-check the Public option for the new class and uncheck it on the old class. Once the class is set up, the final steps are to create Learning Plans and add facilitators, and optionally, students. Adding facilitators and students is simple, and details about creating Learning Plans are covered in the next chapter.
