Almost half of the US public rejects the idea that humans originated via evolution rather than by supernatural design. Moreover, studies demonstrate that even biology teachers have difficulty teaching their students about evolution, often including creationist explanations as well. A typical response to such findings is the argument that greater…

Wertsch's clarification of Vygotsky's claims about the role of social interaction in the development of children's thinking made an important contribution to educational research. Revisiting that clarification, I suggest that "talk" instead of "speech" best describes Vygotsky's concern with the functional dynamics of dialogue rather than the…

Reviews and discusses Piaget's recent work on abstract reasoning. Piaget's distinction between empirical and reflective abstraction is presented; his hypotheses are considered to be metaphorical. (Author/DB)

Presents a brief overview of research and developments in the study of formal operations thought since 1972 along with some speculations concerning future research directions. (Author/MP)

Comments on the articles presented in this issue devoted to the Japanese perspectives on conceptual change. Discusses the overall conveyed message: The human cognitive system is a thematically organized knowledge base with agentive causality as the main mechanism for explain phenomena and analogy as the main mechanism for promoting conceptual…

Comments on the articles presented in this issue devoted to the Japanese perspectives on conceptual change. Suggests that different approaches to knowledge acquisition and conceptual change should be carefully examined in light of their implications for the teaching of science. Discusses critically the issues advanced from the Japanese…

Proposes causal field theory as a model of causal reasoning. Suggests that anomaly detection through comparison with natural events triggers causal reasoning. This anomaly is interpreted in terms of agency; therefore, natural phenomena can be understood through an appeal to agency. The mechanism proposed never changes with development, whereas…

Pragmatic and semantic problem solving are examined as processes that enhance acquisition of mathematical knowledge. It is suggested that development of mathematical cognition involves restructuring and that math teachers can help restructure children's knowledge systems by providing them with situations in which semantic and pragmatic problem…

Proposes analogy as the central mechanism of knowledge acquisition in formal domains. Discusses experimental data on preschoolers' knowledge of one-to-one correspondence and college students' understanding of force decomposition. Suggests that a knowledge base domain is a thematically organized knowledge structure and that thematic relations in a…

Suggests that while doubting that the dichotomy introduced by Subbotsky can cover the entire domain of motivation, he should applaud the emphasis on the neglected but critical importance of motivation in developmental psychology, and the attempt to distinguish different types of motivation, even as contributors to a single behavior. (AA)

Examines two theoretical approaches on how we understand our own and others' minds: a causal explanatory and an interpretive social approach. Explores the relations between these views and suggests that the real challenge of the cognitive revolution is to unite the two approaches, to achieve a causal naturalistic account of the acquisition and…

Suggests that a better understanding of the development of children's theories of mind, requires theoretical perspectives that do not privilege the child who conceptualizes or actively participates in social interactions. Proposes that a better understanding of the relationships among brain, psyche, behavior, and culture should be promoted. (AA)

Examines Astington and Olson's proposal under the context of von Wright's and Hempel's theories of explanation and understanding. Suggests that for taking children's meaning making seriously, researchers should find a principled way to acknowledge the role of interpretation in scientific thinking even in the making of explanation itself. (AA)

Examines the relationship between causal-explanatory and interpretive-hermeneutic approaches to how we understand our own and others' minds. Suggests that the two approaches discussed by Astington and Olson are mutually enlightening but, contrary to the proposed position, are irreducible to each other. (AA)

Points out agreement that the concepts a child acquires are variants of those exemplified by the cultures in which they grow up. Suggests, however, that learners interpret these cultural practices in terms of models causally determined by their cognitive or representational capacities and by the stock of concepts currently available. (AA)
