Overview of Copy Course Component : The Start and end dates specify when learners can access a topic or module. The detailed information is shown in this page.
Overview of Add an existing activity to Content : You can add the different existing activities and can reuse them in the current course.
Overview of Create a new Module : You can create a new module to add the content to it.
If you set a start, end, or due date for a topic or module, it appears on the Upcoming Events page and the Agenda view in the Calendar tool. Setting an end date later than the due date for a topic enables learners to access and complete the topic from the Overdue tab on the Course Schedule page. Topics with a due date and no end date also appear in the Overdue tab on the Course Schedule page.
Note: Adding a due date to a content item that is associated to an assignment overrides an existing end date that is further in the future. The due date also overrides the end date in the Calendar tool.
You must create a new module before you can add topics. You can also create sub-modules (modules within existing modules) to establish a deeper hierarchy.
