Argumentation enables students to engage in real world scientific practices by rationalizing claims grounded in supporting evidence. Student engagement in scientific argumentation activates the negotiation process by which students develop and defend evidence-based claims. Little is known, however, on the intricate process and potential patterns…

This study aims at investigating the change of cognitive presence (CP), which is one of the basic variables for effective learning in online discussions, based on the cognitive style. Cognitive styles of the participants were identified based on the group embedded figures test (GEFT). The participants of the study took part in online discussions…

It is commonly observed that during classroom or group discussions some students have greater influence than may be justified by the normative quality of those students' contributions. We propose a 5-component theoretical framework in order to explain how undue influence unfolds. We build on literatures on persuasion, argumentation, discourse, and…

Describes the Persuasive Arguments Theory (PAT), a noninteractional theory of group decision-making that predicts postdiscussion shifts from prediscussion cognitive arguments, elaborates on it, and advances two models to test the PAT perspective on argument. Finds the second model demonstrates superior predictive ability to the PAT model at some…

This article reports the findings of a research project concerned with children engaging in scientific argumentation. Discussion activities were designed to enable groups of children to use evidence when making decisions. The findings show a variation in the success with which children construct scientific arguments; some groups debate most of the…

Posits a theoretical process model of group argument. Uses the Group Valence Model and two versions of the Distribution of Valence Model to investigate argument-outcome links. Finds that both frameworks were good predictors of group outcomes, and that all argument acts tested were good predictors of group decision choices except those of…

Because of a multiplicity of approaches to small group argument, research in this area often needs to be summarized, condensed, and redirected. Researchers have identified the rational, cognitive and interactive components of argumentation, and have demonstrated that arguments can take several forms and fulfill a variety of functions. The result…

Six papers dealing with decision support and knowledge based systems are presented. Five of the papers are concerned in some way with the use of artificial intelligence techniques in individual or group decision support. The sixth paper presents empirical results from the use of a group decision support system. (CLB)
