Some courses are fairly straightforward, while others require a more structured hierarchy so instructors and students don’t get lost in the chaos. For example, the 100 Ton Master’s License course contains a lot of information that has to be organized for easy study. We do this by segmenting the information into smaller chunks.
A course is the actual package you are getting ready to open. It lists all minimum requirements if there are any (such as minimum days at sea), states required materials (such as practice charts, or other downloadable reference content), and states the desired outcomes both in skills learned and in certificates gained.
A module is a place holder. Think of it as a container. It contains a number of related lessons. For example, the module for Navigation General, in the 100 Ton’s Master’s License course, has a module titled Navigation General. This includes a lesson on Aids to Navigation as well as a lesson on Meteorology. Both relate to navigation but have their own subsets of coursework.
A lesson consists of a number of related topics. The lesson for Meteorology would contain topics on tides, another topic on weather fronts, and yet another topic on ocean currents. It is similar to a module in that it acts as a container. It will list the various skills you will be learning related to that lesson and its information will be a more focused overview. Lessons contain topics and quizzes.
Topics are stand alone concepts. Like the page you are reading now. This is where the information actually gets delivered. Topics contain media and quizzes.
Once all of the lessons in all of the modules are completed, you will be able to take the final quiz for the course.
