This University of Tasmania resource is linked from the CANVAS Essentials module on Collaboration and Communication. Focused specifically on the issues of establishing and supporting effective discussion boards, this resource gives tips on establishing a netiquette guide for students (which they could contribute to formulating) along with a staff guide regarding good practice in facilitation and if the discussion board contributions are to be formally assessed.
