When viewing a Moodle course, the content and resources will be displayed in the main course area.
There are several ways of presenting this material, however the two most commonly used approaches are to group teaching materials by either topic or by week.
To specify a course format:
If you want to group content and resources by date, you should choose a Weekly format and should specify a start date and number of weeks. If you prefer to group your materials by topic then you should select Topic format from the drop down list instead.
If you select a weekly format, Moodle will create sections for you incrementally. Should you wish it to skip a week (in the event that teaching did not take place); you will need to hide the topic manually.
The Navigation block will reflect whatever format you have chosen.
