I first describe competitive and cooperative approaches to argumentation, and I claim that cooperative argumentation aligns with the rhetorical tradition yet needs to be developed further. I focus on civil rhetoric as one form of cooperative argumentation. Building off the abstract description of civility offered by Theresa Enos and Kathleen Blake Yancey, I move to the practical level. Blending a quantitative and qualitative approach, I analyze students' writing from an anthology assignment (which pairs collaboration and argumentation) to determine: What kind of civility moves does the anthology assignment foster? In my analysis, I identify six civility moves: (1) common ground, (2) counter-arguments, (3) logic, (4) nuance, (5) openness, and (6) tone. I then claim that rhetoric which includes the six civility moves-along with attention to ethos and the rhetorical situation's structure-can lead to more productive arguments and argumentation in both our classrooms and wider culture.
