Seeks to identify some of the issues associated with the role of models in scientific explanations. Develops a typology of explanations and explores the notion of appropriateness in scientific explanations. Investigates the nature of models and their contribution to explanations. (DDR)

Analyzes the problem students have in learning the Theory of Relativity. Points out that the results of the study are ambiguous and intriguing. Describes the publication of Lorentz's Transformation Equations, the presentation of two postulates by Einstein, and the rejection of the Electron Theory and the final acceptance of the Theory of…

Outlines and defends claims about the metaphysical nature of the theory of Democritus; the modified theories of Gassendi, Boyle, and Newton; and the chemical atomic theory of John Dalton. (DDR)

Identifies four different types of science stories: (1) heroic; (2) discovery; (3) declarative; and (4) politically correct. Examines the philosophical assumptions that underpin heroic science stories. Considers the implications of these stories in the science classroom. Contains 33 references. (DDR)

Reports on the application of Gowin's epistemology to examples from geological inquiry which yield criteria of excellence responsive to the demands characteristic of geological problems. Supporting this approach is a case study about how geologists apply analogies. Contains 33 references. (DDR)

Discusses how scientific knowledge emerges from social, natural, political, cultural, historical, and economic contingencies of scientific work. Illustrates the advantages of familiarity with research in science and technology. Contains 96 references. (DDR)

Students (n=45) in an introductory course in hydrology used a Vee map to guide their laboratory investigation. The Vee mapping technique was utilized by groups of students working together during the investigation and was graded with a scoring rubric developed by the instructor. At the end of the investigation, students completed a survey…

Presents stories that illustrate how children learned lessons about the nature of science. These lessons include such ideas as observing closely and keep records, accessing resources, and collaborating with each other. Describes the use of a classroom bird station and nature walks in accomplishing the goals. (DDR)

This study investigates gender differences with regard to three factors of scientific literacy. The study involved students (N=772) in Grades 9 and 10. A 100-item multiple choice test based on National Science Education Standards was used to assess scientific literacy while gender differences were explored using analysis of variance procedures.…

This paper reports on the analysis of concept maps of the nature of science constructed by preservice secondary science teachers during a semester-long reflective process. During the 16-week fall semester of 1996, 17 students were enrolled in a 5-credit course. After analyzing all students' concept maps, students were classified as either good…

This paper aims to demonstrate how listening to and discussing the stories inservice science supervisors tell about a novice science teacher provides an opportunity for student science teachers to construct practical knowledge about teaching. Three levels of practical knowledge of teaching are recognized: (1) rules of practice; (2) practical…

This paper reports on the evaluation of an 11-week curriculum created to foster seventh grade students' understanding of scientific modeling. In the curriculum, students engaged in model-oriented activities such as creating non-Newtonian computer microworlds to embody their conceptual models, evaluating their models with criteria, and reflecting…

This paper reports on the analyses of concept maps on the nature of science constructed by preservice secondary science teachers (N=17) during a semester-long reflective process. Analysis of their electronic journals also provides hierarchical evidence. The research questions explored in this study pertain to determining the views of preservice…
