Grouping users
From MoodleDocs
It is useful to put students(or users) in group. Moodle has several flexible ways of doing this. Here is a simple overview of things that can create a complex structure.
- Group: On the Course level can you assign a user to one (or more) group. Basically, in a course you can assign a context(activity) to a group. When members of the group leave the course, they lose their identity with the group.
- Cohort:On the site level you assign a user to a Cohort group. Cohorts are used in the enrolment process. You can enrol a cohort in one or more courses. A cohort looses it's identity once the individuals enter a context of a course but gains it back when they leave.
- A Grouping is a collection of groups. If you had 10 groups, you could combine or mix and match the smaller groups into 2 or more groupings. You can assign a grouping to a context like an assignment.
It can get complex in planning a course where students can belong to more than one group and more than one grouping.
