Setting up a Group Forum
To have students communicate with one another in separate groups, use discussion forums with groups enabled. This configuration will allow the instructor to choose the groups. Students will be able to contribute to only their group's forum, but it is possible for students to view other groups' threads depending on how the group forum is configured.
Enabling Groups in a forum:
1. In the course, click the "Turn editing on" on the top right:
2. Mouse over the forum that you wish to modify. Wait for the Edit button to appear on the far right. Click on it and select Edit Settings.
3. Scroll to the bottom of the page and open the tab Common module settings. Then change the Group mode setting to:
Separate Groups to allow students to contribute and view posts from only their own group.
Visible Groups to allow students to contribute to their own group, but only view posts from other groups.
4. Click the Save and Display button.
