The most important understanding science students should acquire is arguably an understanding of science as a way of knowing, one central to science but not specific to it. Students' own engagement in scientific inquiry and argument can support this developing understanding but does not guarantee it. We report the results of urban adolescents'…

Sixty college students either read a script of a dialog between two individuals holding contrasting positions on the issue of U.S. immigration or read texts containing their two individual position statements on the issue, expressing their same respective views. With this material removed from view, participants expressed in writing their own…

Social studies educators who applaud discourse-based approaches may benefit by adding research on argumentation to their conceptual toolkit. We make the case here for its value, in particular emphasizing that argumentation skill needs to develop, suggesting an apprenticeship model of this development and highlighting evidence supporting it.

Is it important to hear positions opposing one's own from others who genuinely believe them? We examine whether the thinking of those who engage in discourse with peers who hold an opposing view benefit by hearing arguments favoring the opposing position expressed by individuals known to hold this position. We report on 131 young adolescents who…

Agreement has become widespread that students' peer-to-peer argumentation should play a central role in science classrooms. Coordinating evidence with claims lies at the heart of a skilled argument. Yet evidence takes numerous forms that pose different interpretational challenges. Might cognitive limitations on the part of the individual student…

The thinking underlying people's positions on complex issues is often of limited scope or complexity, yet changing minds is notoriously difficult. We investigated the thinking underlying people's positions on the Deferred Action for Childhood Arrivals program. Rather than seek to influence their thinking by engaging them in considering alternative…

In most assessments of students' argumentive writing and in most research on the topic, students write on topics for which they have no specific prior preparation. We examined development in the argumentive writing urban middle school students did as part of a two-year dialogic-based intervention in which students engaged deeply with a series of…

Education for citizenship is more important than ever. The author describes a technology-supported curriculum that engages young teens in electronic discourse with peers on significant personal and societal issues and assists them in decision making on topics ranging from their personal futures to the futures of their communities, nation, and…

The study presented here examines how interacting with a more capable interlocutor influences use of argumentation strategies in electronic discourse. To address this question, 54 young adolescents participating in an intervention centered on electronic peer dialogs were randomly assigned to either an experimental or control condition. In both…

It is now widely accepted, and indeed emphasized in the Next Generation Science Standards, that science education should encompass scientific practice as well as science content. By participating in an intellectual community engaged in the broad range of activities that constitute scientific inquiry, rather than simply mastering isolated science…

Collaborative intellectual engagement is held in high regard in contemporary educational thought as a pedagogical practice of broad value to K-12 students. To what extent is this enthusiasm warranted? Is the practice uniformly productive, or does variability exist in the contexts in which collaboration is effective, the mechanisms involved, and…

We report on an extended effort to introduce and evaluate argumentation as a stand-alone component of the middle-school curriculum. The dialogic-focused curriculum continued over two school years and from a research perspective benefitted from the availability of a closely-matched comparison group who participated in a parallel but non-dialogic…

Central to argument are evidence-based claims, requiring coordination of a claim with evidence bearing on it. We advocate a dialogic approach to developing argument skills and in the work reported here examine the further scaffold of prompts that exemplify functions of evidence in relation to a claim. This scaffold was successful in accelerating…

Argumentation is increasingly recognized as a fundamental intellectual skill, but evidence suggests that few adolescents or adults are skilled arguers. This article reports on an extended (3-year, twice weekly) intervention designed to afford dense practice in dialogic argumentation to middle-school students from traditionally academically…

The concept of science as argument, and the view that engaging in scientific argumentation should play a key role in science education, has become widely endorsed. The case is made here that this objective will be enhanced by broad understanding of the nature of argument skills and their directions and patterns of development. A line of research…
