This study investigated the relationship among 68 high school students' scientific epistemological beliefs (SEBs), cognitive structures regarding nuclear power usage, and their informal reasoning regarding this issue. Moreover, the ability of students' SEBs as well as their cognitive structures for predicting their informal reasoning regarding…

The impulse to investigate the natural world is deeply rooted in our earliest childhood experiences. This notion has long guided researchers to uncover the cognitive mechanisms underlying the development of scientific reasoning in children. Until recently, however, research in cognitive development and education followed largely independent…

This paper draws attention to the literature in the areas of learning, specifically, constructivism, conceptual change and cognitive development. It emphasizes the contribution of such research to our understanding of the learning process. This literature provides guidelines for teachers, at all levels, in their attempt to have their students…

With respect to the specificity and structure of epistemological beliefs, we contend that beliefs about knowledge are reflective of the multidimensional, multilayered, and interactive nature of knowledge. Here we present a model of the nested and reciprocal relations between domain-general and domain-specific epistemological beliefs. Additionally,…

Viewing truth and knowledge as intertextual phenomena, the theory of rhetoric-as-epistemic presented in this paper defines the consensus model as unanimity and the "discourse community" model as involving primary texts (rather than people). A theory of intertextual reality and knowledge is developed, based on five major assertions: (1)…

The purpose of this review is to provide educational practitioners with a brief overview of cognitive load theory (CLT) and its major implications for learning. To achieve this objective, the article includes a short description of human cognitive architecture as conceived by cognitive load theorists. Following this overview, the article provides…

The prominent cognitive theories of probability judgment were primarily developed to explain cognitive biases rather than to account for the cognitive processes in probability judgment. In this article the authors compare 3 major theories of the processes and representations in probability judgment: the representativeness heuristic, implemented as…

Evolution by natural selection may be characterized as a system in which a large store of genetic information will persist indefinitely while it remains coordinated with its environment but will continuously produce small random variations that are tested for environmental effectiveness. In any environment, effective variations will persist while…

The world presented to our senses is essentially continuous in space and time. The simplest observations of children have shown that we are not born with ways of "breaking up" the world. The structures of our knowledge must be developed, and the major issue this paper considers is how those structures develop. The discussion focuses on Jean…

Good thinking can be placed within a descriptive framework which includes a state of doubt about what to do or believe; goal, possibilities, and evidence seeking; and evidence use. The framework is useful in describing all types of thinking, although the search process may differ in the degree of control the thinker has over his search. Examples…

Two experiments examined whether the correlation between advances on theory-of-mind and executive function tasks results from the tasks posing the same executive demands among 3- to 6- year-olds. Findings indicated that performance on the dimensional change card-sorting task (a measure of executive function) was correlated with performance on the…

Reviews Karmiloff-Smith's "Beyond Modularity," suggesting that her work highlights phenomena that seem counter intuitive when regarded from current developmental frameworks, and advocates that understanding them requires more complex perspectives than can be supported by either extreme nativist or domain-general models of cognitive…

Isolates domain-general decision-making (DM) processes in their specific instantiations in adult second-language acquisition (SLA). Some impediments to success in SLA may be artifacts of mature (adult) DM procedures. (Contains 29 references.) (JP)

Activity theory posits that culturally organized actions guide the acquisition and organization of knowledge. This theory was applied to the organization of knowledge within a large milk processing plant. The dairy was found to be organized by social knowledge, yet individuals creatively synthesized several domains of knowledge to organize their…

Most research on personal epistemologies has conceived them as made up of relatively large, coherent, and stable cognitive structures, either developmental stages or beliefs (perhaps organized into theories). Recent work has challenged these views, arguing that personal epistemologies are better understood as made up of finer grained cognitive…
