Many urgent problems that societies currently face—from climate change to a global pandemic—require citizens to engage with scientific information as members of democratic societies as well as to solve problems in their personal lives. Most often, to solve their epistemic aims (aims directed at achieving knowledge and understanding) regarding such socio-scientific issues, individuals search for information online, where there exists a multitude of possibly relevant and highly interconnected sources of different perspectives, sometimes providing conflicting information. The paper provides a review (...) of the literature aimed at identifying (a) constraints and affordances that scientific knowledge and the online information environment entail and (b) individuals' cognitive and motivational processes that have been found to hinder, or conversely, support practices of engagement (such as critical information evaluation or two-sided dialogue). Doing this, a conceptual framework for understanding and fostering what we callonline engagement with scientific informationis introduced, which is conceived as consisting of individual engagement (engaging on one's own in the search, selection, evaluation, and integration of information) and dialogic engagement (engaging in discourse with others to interpret, articulate and critically examine scientific information). In turn, this paper identifies individual and contextual conditions for individuals' goal-directed and effortful online engagement with scientific information. (shrink)

Researchers in science education have converged on the view that 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. (shrink)

The present study has two goals: to explore elementary students’ understanding of evidence and the ways they deploy it to construct arguments, and to examine whether eliciting their concept of evidence during argumentation improves students’ evidence-based reasoning. Individual semi-structured interviews were conducted with 4th and 6th graders in a public school in Mexico. We found significant differences between groups regarding the concept of evidence, with better performance in the older group. A positive correlation between the concept of evidence and the (...) quality of evidence-based reasoning was found. Also, three performance profiles were observed after eliciting the concept of evidence when grade was excluded as a factor. Results suggest that the concept of evidence plays an essential role in developing argumentative competence in pre-adolescence. (shrink)

Studies of adolescents and young-adults suggest that deliberative dialogue, a form of consensus-seeking argumentation, leads to stronger learning outcomes than persuasive dialogue. However, this research has not been informed by an analysis of dialogue among more experienced arguers. In the present study, we compare the deliberative and persuasive dialogues of novice and experienced arguers to better understand the difference between these two forms of discourse at differing levels of argumentative expertise. Our results confirm theoretical distinctions between deliberation and persuasion. Results (...) also suggest that greater experience in argumentation is associated with a richer array of argumentative purposes, producing more cohesive, intersubjective and dialectically relevant dialogue. The implications of these findings for learning are discussed. (shrink)
