A discussion forum is a tool that allows students and educators to have an online written dialogue. Forums can form the basis of open discussions, or they can be used to facilitate activities where the tutor sets a task and students post their responses to it.

In both types of forums, you will typically see the original topic or question with all the responses grouped underneath in a nested discussion thread. These discussions can be left open for a long period of time, or closed and left as a resource for students to refer back to.
