For this class, substantive means that your replies have substance, that it helps further the discussion of course content and move the discussion forward. Substantive posts will often include contributions of additional ideas and sources, insights or questions about classmates comments, connections to the course readings, ways of applying the lessons from the course, etc. Short comments, such as “Good idea” or “I agree,” do not constitute substantive posts on their own. Neither do comments that are unrelated to the topics at hand (for example, I saw that movie too!) If you say you agree about something, please explain why you agree, and add an additional insight or question.
