I've set up a Moodle course and have several groups. Each group has a course coordinator and a mentor (archetype role is non editing teacher). Both roles are added to each group. I've forced the group settings to separate groups so that teachers (for us this is coordinators and mentors) only receive notifications from their group and only see the activities from their group. However I'm getting reports that notifications are going to teachers of other groups. Any easy to follow advice out there?
Step 1: Add your users into respective groups.
Step 2: After that create "grouping" and assign groups into grouping.
Step 3: create activity in course, go to "Group submission settings". set Yes to Students submit in groups and Require group to make submission. Go to Common module settings and then choose your desire group for "Grouping" .
Hope this resolves your issue.
