The synthesis of four instructional models for argumentative writing--the Toulmin, Hiduke, Winder, and Crebbe-Debate approaches--with basic discourse theory produces a practical and positive method of teaching college students to write effective persuasive essays. A battery of questions based on a modified communication triangle--subject (problem), writer (rhetoric) and audience (opposition)--helps students to analyze argument components. Adapted from the Crebbe-Debate approach, peer evaluation of arguments emphasizes the importance of the audience in persuasive essays. Combining inductive analysis of writer, subject, audience, and sense of audience immediacy with solid organizational options, this method teaches students not simply what weakens arguments, but how to write good persuasive essays.
