In preparation for class, students read two essays related to a controversial issue, with one essay in support of and the other in opposition to a particular idea or viewpoint. In class, the teacher presents a statement that reflects one of the two sides. Students individually decide whether they agree or disagree, writing down their rationale. They then go stand in front of one of four signs the teacher has posted around the room (Strongly Agree, Agree, Disagree, and Strongly Disagree) and take turns presenting their rationales for the position they have assumed. They are then invited to move to another sign if the arguments they hear persuade them to change their minds. This activity encourages students to think critically, gives them opportunities to practice developing and presenting arguments, and to listen carefully to others' points of view. Additionally, by requiring each student to choose the corner that represents their position and articulate their rationale for that position, it ensures all students make some level of personal commitment to the issue.
