Assessment of the ways students generate arguments in science education: Current perspectives and recommendations for future directions

Abstract

Theoretical and empirical research on argument and argumentation in science education has intensified over the last two decades. The term "argument" in this review refers to the artifacts that a student or a group of students create when asked to articulate and justify claims or explanations whereas the term "argumentation" refers to the process of constructing these artifacts. The intent of this review is to provide an overview of several analytic frameworks that science educators use to assess and characterize the nature of or quality of scientific arguments in terms of three focal issues: structure, justification, and content. To highlight the foci, affordances, and constraints of these different analytic methods, the review of each framework includes an analysis of a sample argument. The review concludes with a synthesis of the three focal issues and outlines several recommendations for future work. Ultimately, this examination and synthesis of these frameworks in terms of how each conceptualizes argument structure, justification, and content is intended to provide a theoretical foundation for future research on argument in science education. © 2008 Wiley Periodicals, Inc.
