How do I set up a Group Discussion Assignment?
Groups are a subset of a course with a course-like environment including their own Calendar, Discussion board, and Collaboration tools. Only students added to a group have permission to see and use the respective tools within the group.
A group discussion assignment creates an identical discussion topic in each group category. When students reply to the discussion topic they do so within their group environment, which is linked to the course from which the assignment was created.
