Discussions can be enabled for specific Groups of learners if you are using the Native Discussion app. This article discusses the steps for enabling Group Discussions that are private to the members of a group.
Before performing the steps below, make sure you've enabled the Native Discussion app in your school. Click here to learn more.
In the top navigation bar, click Community and select Groups. Open a Group (or create a new Group).
Click Actions and select Edit Group.
Check the box next to Enable Private Discussions. Click on the Update button.
Once you've enabled private discussions for a group, it will apply to all courses with activities that have discussion boards turned on (learn how to enable discussion boards in activities here).
In these activities, learners will see a second tab in the discussion board. These discussions are private, and only members of the group and the moderators can see and participate in the conversation.
