Modules vs Courses
Think of Modules and Courses in terms of books. Modules are the chapters within a book, whereas a Course is a book itself. Think of your favorite book. What's the title of it? That is the name of the Course. The content would be the Modules, separated by chapters like chapter books.
Modules are where you upload your content using existing training materials, such as PowerPoint slide decks, Word/PDF documents, SCORM, and video. These types of modules are known as On-Demand modules. To track offline training, you would create an In-Person module.
Courses are comprised of one or more modules. To distribute training to your trainees, you enroll them in a course containing the module(s) you want them to complete.
