The forum activity module enables participants to have asynchronous discussions i.e. discussions that take place over an extended period of time.

There are several forum types to choose from, such as a standard forum where anyone can start a new discussion at any time; a forum where each student can post exactly one discussion; or a question and answer forum where students must first post before being able to view other students' posts. A teacher can allow files to be attached to forum posts. Attached images are displayed in the forum post.

Participants can subscribe to a forum to receive notifications of new forum posts. A teacher can set the subscription mode to optional, forced or auto, or prevent subscription completely. If required, students can be blocked from posting more than a given number of posts in a given time period; this can prevent individuals from dominating discussions.

Forum posts can be rated by teachers or students (peer evaluation). Ratings can be aggregated to form a final grade which is recorded in the gradebook.

Forums have many uses, such as

• A social space for students to get to know each other
• For course announcements (using a news forum with forced subscription)
• For discussing course content or reading materials
• For continuing online an issue raised previously in a face-to-face session
• For teacher-only discussions (using a hidden forum)
• A help centre where tutors and students can give advice
• A one-on-one support area for private student-teacher communications (using a forum with separate groups and with one student per group)
• For extension activities, for example ‘brain teasers’ for students to ponder and suggest solutions to
