Moodle course formats

Weekly format

The course is organised week by week, with a clear start date and a finish date. Each week consists of activities. Some of them, like assignments, may have "open windows" of, say, two weeks after which they become unavailable.

Topics format

Very similar to the weekly format, except that each "week" is called a topic. A "topic" is not restricted to any time limit. You don't need to specify any dates.

Social format

This format is oriented around one main forum, the Social forum, which appears listed on the main page. It is useful for situations that are more freeform. They may not even be courses. For example, it could be used as a departmental notice board.
