Students' poor argumentation in the context of socio-scientific issues has become a concern in science education. Identified problems associated with student argumentation in socio-scientific issues are misevaluation of evidence, naive nature of science conceptualizations, and inappropriate use of value-based reasoning. In this theoretical paper, the authors propose that incorporation of decision-making research findings to argumentation research may help students overcome these problematic areas. For this aim, decision-making research findings about value-focused decision-making framework and common heuristics have been discussed. Specifically, the authors propose that explicit teaching of argumentation research should provide students a decision-making framework in which students can consider their values about a socio-scientific issue and assess different alternatives as well as incorporate teaching about common heuristics. The authors believe that this incorporation is necessary for a quality student argumentation in socio-scientific issues. (Contains 1 figure.)
