Abstract
In this paper, I will discuss new approaches to investigating increasingly influential, yet under-researched, theoretical assumptions regarding the role dialogic interaction plays in cognitive development. I will present a psychological theory that refines social learning models by integrating them with schema-theoreticperspectives. I will then review Philosophy for Children pedagogy, demonstrating how it can provide a useful context for conducting empirical studies of learning theories that emphasize the use of dialogue for promoting individual argumentation development. Next, I will describe a research design and data-analytic tools used to examine the educational potential of engagement in a philosophical dialogue for the development of argumentation. Finally, I will present preliminary results of a study evaluating the connections between 1) specific features of group interactions experienced by elementary school students and 2) individual student performance on multiple measures of argumentation.
