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…

Kuhn (1970) considered textbooks to be good "pedagogical vehicles" for the perpetuation of "normal science". Collins (2000) has pointed out a fundamental contradiction with respect to what science could achieve (create new knowledge) and how we teach science (authoritarian). Despite the reform efforts, students still have naive views about the…

The objective of this study is to facilitate progressive transitions in chemistry teachers understanding of nature of science in the context of historical controversies. Selected controversies referred to episodes that form part of the chemistry curriculum both at secondary and university freshman level. The study is based on 17 in-service…

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…

The paper critically appraises the concept-learning and developmental perspectives in science education to show that Pascual-Leone's Theory of Constructive Operators leads to a progressive problem-shift between Piaget's epistemic subject and Pascual-Leone's metasubject. (SM)

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…

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 oil drop experiment is considered an important contribution to the understanding of modern physics and chemistry. The objective of this investigation is to study and contrast the views and understanding with respect to the experiment of physicists or philosophers of science with those of authors of physics or chemistry textbooks and…
