Overview
First, I have to write one well-developed body paragraph (10–15 lines) that begins with a general topic sentence and gradually moves to more specific supporting details and explanations. Then, after posting my paragraph, I must reply to two classmates. Each reply should be 8–12 lines long, summarize one key idea from the classmate's paragraph, and continue the discussion by asking a meaningful question, sharing a personal experience, offering a different point of view, or expanding on one of their ideas.
