Modules are used to organize course content like folders on a computer or chapters within a book. Modules can be set by time frame (e.g., Week 1), by topic (e.g., Cellular Biology), or by course components (e.g., Final Project).
A module must be created before files can be added to a D2L course.
By default all modules are set to "Visible."
Submodules are optional and allow further organization of content.
Note: When viewed within a main-level module, submodules do not display descriptions or dates attached to topics. To view descriptions and dates, users will need to navigate directly into the submodule. Because of this, it is recommended to use main-level modules for overarching organization.
Once a module is created, files can be added. View
