Single Activity course format The single activity format has one section, and allows the teacher to add one activity to the course. When using single activity format, you can select which activity to use for the course from the Type of activity menu. This course format replaces the SCORM format in earlier versions of Moodle, as it is possible here to select a SCORM package as the single activity. Single activity format can be used in most themes. If your course is using the Snap theme, think about using the Weekly or Topic format for a better user experience.
