The authors of this paper portray the perspective of Professor Leon Cooper, a theoretical physicist, Nobel laureate, active researcher, and physics textbook author, on teaching science and on the nature of science (NOS). The views presented emerged from an interview prepared by the authors and responded to in writing by Professor Cooper. Based on…

The objective of this study is to facilitate in-service chemistry teachers' understanding of nature of science and what "ideas-about-science" can be included in the classroom. The study is based on 17 in-service teachers who had registered for a 11-week course on "Epistemology of Science Teaching" as part of their Master's degree program. The…

Constructivism in science education has been the subject of considerable debate in the science education literature. The purpose of this study was to facilitate chemistry teachers' understanding that the tentative nature of scientific knowledge leads to the coexistence and rivalries among different forms of constructivism in science education. The…

Reports on a study designed to: (a) understand the nature of science as progressive transitions in heuristic principles; and (b) provide a rationale for the inclusion of three more characteristics of the nature of science to the original five suggested by Smith and Scharmann. Concludes that nature of science manifests in different topics of the…

Concludes that Pascual-Leone's theory extends Piaget's negative heuristic by introducing antecedent variables and at the same time enriches the positive heuristic by introducing metasubjective task analysis, which leads to a progressive problemshift. (Author/PR)

Historians and philosophers of science have recognized the importance of controversies in the progress of science. The objective of this study was to facilitate in-service chemistry teachers' understanding of conceptual change based on alternative philosophical interpretations (controversies). Selected controversies formed part of the chemistry…

Analyzes (n=32) Brazilian secondary school students' interactions (conflicts, controversies, and arguments) as they participate in an intact 9th grade classroom activity designed to facilitate their understanding of heat energy and temperature. Reports that the differentiation between heat energy and temperature constitutes considerable…

This paper helps to clarify the role of empirical evidence in psychological and epistemological theories. Following Galileo's idealization, epistemological theories do not describe the behavior of individuals in the real world. It is only when the "impediments" of the real subjects are gradually removed by experimental manipulation that…

Discusses differences between the epistemic and the psychological subject, the relationship between the epistemic subject and the ideal gas law, the development of general cognitive operations, and the empirical testability of Piaget's epistemic subject. (PR)

Establishes a relationship between students' understanding of gases and its parallels in the history of science. Finds that college freshman students' alternative conceptions about gas behavior are resistant to change and recapitulate theories scientists held in the past, such as the Lattice Theory of Gases. (Contains 52 references.) (Author/WRM)

Examines the role of empirical evidence in the interpretation of psychological and epistemological aspects of Piagetian theory. Concludes that Galileo's method of idealization has important implications for the construction of a neo-Piagetian epistemological theory. Contains 35 references. (Author/WRM)

The effect of manipulation of the perceptual field factors on undergraduate student performance in proportional reasoning tasks was investigated. Evidence was found to support the hypothesis that the manipulation of the perceptual field factor can affect student performance. Reports data correlated with the Group Embedded-Figures Test. (CW)

Maintains that, for a cognitive construct to be accepted as explanatory, it must specify target behaviors, posit antecedent variables, and indicate how the antecedent variables can be measured independently of behavioral changes. Discusses epistemological tools that can be used in similar fashion. (CFR)
