Abstract

The development of a framework for coding argumentations schemes in the transcripts of classroom dialogical deliberations on controversial, socioscientific topics is described. Arriving at a coding framework involved resolving a number of complex issues and challenges that are discussed in order to create practical remedies. The description of the development process is based on audio recordings and written exchanges between the authors as they attempted to resolve differences in the interpretation and application of argumentation schemes . These deliberations address theoretical and practical concerns for adapting notions of argumentation schemes to the practical context of analyzing authentic classroom interactions. The framework was developed to accommodate research and curriculum development in school science education. A practical framework for analyzing argumentation in authentic classroom contexts is proposed and implications for science education and argumentation theory are raised
