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.
