This is a relatively formal method of presentation and is comparatively easy to organize. it allows for a systematic and relatively complete expression of ideas in an uninterrupted fashion. By it complex subjects and problems may be divided readily into logical component parts. Structuring of the presentation may be obtained readily by agreement among the participants prior to the symposium. There should be a minimum of duplication and repetition and time allotments should lead to precise, logical presentations. Excellent control of the subject matter, as well as of the length of the symposium. May be attained by mutual agreements among the participants made prior to the symposium. It must depend upon empathy with the speaker or subject matter, or upon competitive points of view, to develop audience interest and involvement. Hence it has limited usefulness in this respect. There is a minimum of interaction between the participants
