Moodle - Forum activity (staff/faculty)


The forum activity allows students and teachers to exchange ideas by posting comments. There are five basic forum types. Forums can be configured so that the posts are graded by either the teacher or other students.

This article is about how to add a forum. To learn strategies for facilitating discussions in forums, see this related article:

How to Add a Forum

Continue with a video presentation and/or read below for text:

The Forum can be used in many ways: from simple communication of information from the instructor to the class (as on a bulletin board), to the assessment of learner discussions.


1. From the main course page click on the Turn Editing on/off button in the top right of the page

Turning Editing on

2. Locate the section in your course where you want to add the Forum poll. Click Add an activity or resource, choose Forum.

3. Type a name into the Forum name field. This will appear as the activity title. The Description field is optional, but it's recommended that you describe the purpose of the Forum.

Forum type

There are 5 types of forums to choose from when creating a discussion forum. The default is Standard forum for general use.

forum type

  1. A single simple discussion: A single discussion topic which everyone can reply to.
  2. Each person posts one discussion: Each student can post exactly one new discussion topic, which everyone can reply to.
  3. Q and A forum: The instructor writes the initial post or question, and then students must post their reply and wait for the editing delay (30 minutes) to expire before being able to see the replies from other students.
  4. Standard forum displayed in blog-like format: Anyone can start a new discussion or reply, but the discussion topics are displayed on one page with “Discuss this topic” links.
  5. Standard forum for general use: The Moodle default. Anyone can start a new discussion or reply.

Subscription and tracking

You can change the subscription mode for a forum. When a participant is subscribed to a forum it means they will receive email copies of forum posts. Read tracking, if enabled, allows participants to track read and unread posts in the forum.

There are four subscription mode options:

  1. Optional subscription - Nobody is subscribed initially. Participants can choose to subscribe or unsubscribe.
  2. Forced subscription - Everyone is subscribed and cannot unsubscribe. This is the default for a course announcements forum.
  3. Auto subscription - Everyone is subscribed initially but can choose to unsubscribe.
  4. Subscription disabled - Subscriptions are not allowed.

If you change a live forum to optional subscription, everyone will be unsubscribed from the forum and will need to re-subscribe to receive email notifications.

If course visibility is set to hidden, as it usually is before the courses starts, course participants will not receive email notifications for any posts made during this time.

Discussion locking

Instructors can lock forum discussions after a period of inactivity (e.g. 1 day, 1 week, 1 month, etc.) so that students can no longer reply to to the forum. Permitted users (e.g. instructors, PAs, etc.) can unlock discussions by posting a reply. When students click to view a locked forum thread, they will see a message that the discussion has been locked. They won't have a reply button and will not be able to reply to posts. However, teachers and anyone with the capability to reply to locked discussions can unlock them simply by replying. The drop-down menu provides options for locking the forum discussion after a period of inactivity. The default is for discussions to never be locked, allowing students to contribute at any time.

NOTE: If discussion locking is enabled, there is no notification that appears automatically to indicate this to students. The discussion page appears the same, whether or not discussion locking is enabled. The screenshot below shows a student-view of a forum where forum discussion locking has been enabled. Note that there is no automatic warning indicating that the forum will be locked. This means that students may not know that discussion locking is enabled. 

no lock notification

We suggest adding a note in the description of the forum to indicate that the discussion will be locked after a certain amount of time. In the screenshot below, you can see the warning that the instructor wrote when setting up the forum. This lets students know that discussions in this forum will lock after a period of inactivity:

Group Mode

Use to set up class-wide and team forums.

group mode

This setting has 3 options:

  1. No groups - A class-wide forum.
  2. Separate groups - Each group member can only read and reply to the their own group's posts; other groups are not visible.
  3. Visible groups - Similar to separate groups but participants can also see (but not post or reply to) forum posts from other groups.

Restrict access

Use to set-up when students can access the forum.

add restriction

restrict by time

4. When you have finished setting up the forum, click Save and return to course. If you want to review the forum, click Save and display.
