The Course Builder in D2L is designed to help add and organize the Content area of the course.
The Course Builder can be used to create modules, add topics to Content, and duplicate modules.
Note: If Course Administration page is set to show tools by category (the default), Course Builder will be under the heading "Site Resources." If the Course Administration page is set to view by name, then Course Builder will be listed alphabetically.
Note: Anything added in the Notes section will not visible to students.
Modules can be copied in the Course Builder. When a module is copied, it will duplicate the structure, so any topics or sub-modules within the module will also be copied.
