This model emphasized the importance of estabilshing netiquette rules early and to establish a pattrn of communication. The best way for instructors to manage communication in a course is to be involved, consistent, and to model the appropriate behavior as well as delineate the expectations clearly. The example of appropriate postings and responses and use of a rubric for discussion boards is very relevant. In my experience, most students won't expand on the conversation in a discussion board beyond, "I agree/disagree", etc. unless the instructor indicates that the student must be more participative, thorough, and reflective in their responses.
