Discussion takes place in a physical classroom. The instructor often leads and controls the focus of the discussion to reach a conclusion in a limited amount of time. Since time is limited, responses must typically be formulated quickly. There could also be some intimidation of speaking live in a classroom setting, but there is also the benefit of visual cues of fellow students and the instructor. Students have more of an opportunity to develop well thought out, researched, discussion responses. The students often carry the bulk of the discussion interaction with the instructor acting as a facilitator only interjecting when necessary. The online discussion evolves over a period of time longer than that of the face-to-face classroom (often more than one week) which allows the time and flexibility for all students in the course to contribute and reach conclusions together.
