Moodle Course Format
Moodle Courses have several layout formants to organize a course in the best manner possible. To edit the course format, click "Edit Course Settings" and each format is under "Course Format".
Social format is only used for discussion forums so that students can interact with one another on one page. It is not particularly useful for implementing entire courses onto.
Single Activity Format
Single Activity format contains only one Activity for students to do. If you only need to use moodle for one activity, for instance a one quiz, use this format.
One Topic Format
One topic format is particularly useful if you have a very long course on Moodle and do not want to scroll through the topics. Instead, each tab contains a topic and students can access each topic by clicking on each tab at the top of the screen.
Collapse format is also useful for large courses with a lot of content. They are able to expand sections by clicking on them thereby saving space on the screen.
