Modules can be accessed by opening For teachers - Modules page. Here you can search for modules by name and labels, and choose which modules to display by categories (My modules, Modules shared with me, Public modules).
Modules are structured containers for learning units. Their purpose is to build complex learning materials from learning units by placing and arranging learning units to blocks and difficulty levels within a module.
Modules filled with learning units have to be added to learning routes. The learning routes are sent to students to play them.
One module can be added to multiple learning routes. Changes made to the module are automatically reflected in all learning routes where the module is added to.
Learning units within a module can be accessed for editing directly in the module list or on the Learning units - My learning units in modules page. Changes made to the learning unit are automatically reflected in the module where it is added to.
