Classes exist as containers to hold content. If your administrator configured a schedule for capturing the course, those scheduled capture dates are listed as classes on the course's class list page.
Each class can contain one video and one presentation. For scheduled classes/captures, the video placeholder is (or will be) occupied by the recorded capture for the class. However, you may have additional materials you want to provide for the course or a particular class. In this case you may need to create a new class to hold that content.
You can create a class with a corresponding date to an existing class, or create a class with a different date/time, or one with no specific date and time.
If creating a duplicate class to one that already exists, know that can create one additional class that duplicates the date/time of an existing class, however creating more than one duplicate may result in the original class disappearing from the list.
If this happens, simply edit the start date/time of the second class, offsetting by one minute. The original will re-appear, complete with any class content.
All new classes created appear at the top of the class list. Be sure to provide a Class Name and Description that makes clear the purpose or contents of the class for students.
To create a new class
NOTE: If you have a Start date, you must enter time and duration. If you have no date, the class must have a name. If you create a class with no date, be sure to provide a name and description that informs users what the purpose of the class/content is.
