 Cohorts, bulk enrol. Cohorts are site-wide or category-wide groups which can easily be enrolled into courses. There are two ways of enrolling cohorts and they have different benefits. Let's first create a cohort as admin and then investigate both methods. From site administration, users, cohorts, our admin can add a new cohort, either in the system, site-wide context as here, or in the category context. The cohort will be visible to course teachers to use unless she hides it. She assigns some users and then, from site administration, plugins, enrolments, manage enrol plugins, she can enable cohort sync, checking the default settings meet her requirements. Now, teacher Mr Wilson has two options. Cohort enrolment from course navigation, participants, enrol users, allows him to enrol cohort members as individuals. So here we see him accessing his digital literacy course from enrol users, selecting a cohort, assigning them a role and quickly enrolling them. This is useful if our teacher doesn't expect the cohort to change often as he would manually need to enrol or unenrol more members. If he wanted to use groups, he'd also have to manually allocate them to groups. A second option is cohort sync when enabled by admin. Cohort sync from course navigation, participants, enrolment methods also allows him to enrol in bulk, but he can put the cohort members into groups and they are automatically synchronized when any changes are made to the cohort. Here we see our teacher in his Oceans for All course adding the cohort sync method. He then needs to choose the cohort and, if desired, either an existing group or a newly created group. From the participants list now, we see the cohort members enrolled into a new group. As admin, let's go to the cohort and remove mark and add a new member, Paula. What happens then is that in the digital literacy course using cohort enrolment, nothing has changed since there is no synchronization here. However, if we go to the Oceans for All course, we see that user mark has been removed and user Paula has been added to the group. To summarize, cohorts allow groups of users to be added to courses in bulk either by cohort enrolment or cohort sync. With cohort sync, members can be put into groups upon enrolment and changes to the cohort are reflected in the course.
