How do I add a module?
Modules are used to organize course content by weeks, units, or whatever organizational structure works for your course. With modules, you are essentially creating a one-directional linear flow of what you would like your students to do. Once you create modules, you can add content items, set prerequisites, and add requirements.
Note: If the Course Home Page is set to modules, modules can be added and managed directly from the Course Home Page.
If you want to restrict the module until a specific date, you can lock the module.
If you have added at least one module to your course, you can require a prerequisite module. A prerequisite module means students must complete the added modules before they can view the new module.
