Deliberation versus Dispute: The Impact of Argumentative Discourse Goals on Learning and Reasoning in the Science Classroom

Abstract

Researchers in science education have converged on the viewthat argumentation can be an effective intervention for promoting knowledge construction in science classrooms.However, the impact of such interventions may be mediated by individuals’ task goals while arguing. In argumentative discourse, one can distinguish two overlapping but distinct kinds of activity: dispute and deliberation. 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 discourse goals on both content learning and argument quality in science.
