Abstract

Gregory reports on a study by researchers from Ohio State and Pennsylvania State Universities that evaluated nine programs of classroom discussion. The programs were evaluated on their evidence of discourse features that have been shown in research literature to characterize quality discussions. Two programs, Philosophy for Children and Collaborative Reasoning, were found to provide the richest opportunities for individual and collective reasoning, due to the way teachers in these programs model and scaffold argumentation and cultivate a culture of dialogic inquiry in the classroom.
