This paper reports some methodological approaches to the analysis of argumentation discourse developed as part of the two-and-a-half year project titled "Enhancing the Quality of Argument in School Science" supported by the Economic and Social Research Council in the United Kingdom. In this project researchers collaborated with middle-school science teachers to develop models of instructional activities in an effort to make argumentation a component of instruction. We begin the paper with a brief theoretical justification for why we consider argumentation to be of significance to science education. We then contextualize the use of Toulmin's Argument Pattern in the study of argumentation discourse and provide a justification for the methodological outcomes our approach generates. We illustrate how our work refines and develops research methodologies in argumentation analysis. In particular, we present two methodological approaches to the analysis of argumentation resulting in whole-class as well as small-group student discussions. For each approach, we illustrate our coding scheme and some results as well as how our methodological approach has enabled our inquiry into the quality of argumentation in the classroom. We conclude with some implications for future research in argumentation in science education.
ABSTRACT:In argumentative discourse, there are two kinds of activity-dispute and deliberation-that depend on the argumentative task goal. In dispute the goal is to defend a conclusion by undermining alternatives, whereas in deliberation the goal is to arrive at a conclusion by contrasting alternatives. In this study, we examine the impact of these tasks goals on the quality of argumentative discourse. Sixty-five junior high school students were organized into dyads to discuss sources of energy. Dyads were formed by members who had differing viewpoints and were distributed to one of two conditions: 31 dyads were asked to discuss with the goal to persuade the partner, and 34 were asked to reach consensus. Argumentation was analyzed using a schema based on Toulmin (1958). Eleven different argumentative structures resulted from the combination of Toulmin's basic elements. Students in the consensus group scored significantly higher than students in the persuasion Correspondence to:
