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 construct of metacognition appears in an ever increasing number and range of contexts in educational, developmental, and cognitive psychology. Can it retain its status as a useful construct in the face of such diverse application? Or is it merely an umbrella term for diverse mental phenomena that are loosely if at all connected? Here I argue…

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…

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…

We examine how extended engagement in argumentation with peers leads to enhanced metalevel understanding of argumentive discourse. Following such engagement, young adolescents demonstrated enhanced understanding of counterargument and use of evidence as objectives of skilled argumentation, relative to a nonparticipating comparison group. Among the…

In a pedagogical method increasing in popularity, students of all levels--from elementary to post graduate--are likely to be asked to engage in debate with peers. How they understand the purposes and values of argumentive discourse is likely to affect its effectiveness. The 3 studies presented here involve junior high school, senior high school,…

Museum educators often think about what they want children to take away with them from museum visits. But at least as important is what children bring to these visits. Research in developmental psychology shows that children and adolescents progress through a sequence of ways of understanding knowledge and knowing--understanding that lies at the…

Outlines a developmental model of critical thinking that is derived from contemporary research on directions and processes of intellectual development in children and adolescents. Identifies metacognitive, metastrategic, and epistemological forms of second-order cognition that enter into critical thinking. (Author/SLD)

We propose a concept of intellectual values as (a) shared within a group and defined by the extent to which intellectual engagement is regarded as worthwhile to the group's interests, (b) supported by an epistemological belief system, and (c) an important dimension of sociocultural practice and learning. A series of studies is described in which…

Subjects between adolescence and older adulthood were asked to describe their causal theories for three social problems. Links between informal reasoning, as displayed by subjects in the study, and scientific reasoning are examined, and the development of reasoning competency is discussed. (BC)

Asserts the importance of developing in students an intrinsic valuing of intellectual activities as the firmest basis for sustaining intellectual motivation. Discusses how to develop in students an understanding of what it means to learn and to know, including a movement up the levels of epistemological understanding from realist to evaluativist.…
