Presents the results of a study that identifies misconceptions in chemistry by means of a two-tier diagnostic instrument. Data indicate that similar misconceptions are held by both Singaporean and Australian populations. Focuses on covalent bonding and structure. (DDR)

Recommends the use of concept mapping in science teaching and proposes that it be presented as a creative activity. Includes a sample lesson plan of a potato stamp concept mapping activity for astronomy. (DDR)

This paper examines the nature of physics students' knowledge, the means to identify alternative conceptions, and possible methods to overcome misconceptions. This examination is a survey of the techniques and ideas of a large number of researchers who are seeking their own solutions to this problem. An examination of the nature of knowledge…

Explores the integrative nature of problem-based curricula and describes a systematic process for content review in a problem-based curriculum. Utilizes consultation among students, faculty, and the clinical community. Delineates the advantages of this process. (DDR)

Considers the idea that concept mapping has applications beyond those associated with student assessment. Outlines further uses for concept mapping in the classroom along with suggestions for implementing this powerful tool. (DDR)

Investigates Grade 12 students' understandings of the nature of chemical bonds and the energetics elicited across five familiar chemical reactions following a course of instruction. Discusses the many ways in which students can misconstruct concepts and principles. Contains 63 references. (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)

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)

This paper discusses various aspects of conceptual change instruction and research related to conceptual change strategies. The role played by teachers in the conceptual change process has been neglected in the research and understanding that role requires that: (1) the Conceptual Change Model of Posner provide a reasonable framework for thinking…

This paper reports on an interdisciplinary theoretical framework for the characterization of models and modeling that can be useful in application to chemistry education. The underlying argument marks a departure from an emphasis on concepts that are the outcomes of chemical inquiry about how knowledge growth occurs through modeling in chemistry.…

Reports research that investigates the encoding that students use to develop molecular models at the undergraduate level. Focuses on the translation between symbolic and subatomic representations of molecules. (Contains 31 references.) (DDR)

Contributes to a reflection on the possibilities and the limits of a non-naive use of the history of mathematics for educational purposes. Discusses a problem related to the hypotheses that make it possible to confront past and modern conceptual developments. Contains 45 references. (DDR)

Presents evidence from the Yupiaq culture that demonstrates a body of scientific thought and epistemology that differs from that of Western science. Contends that this information can provide a more culturally relevant framework for science learning for some students. Contains 20 references. (DDR)

Investigates the effects of a constructivist versus objectivist learning environment on college students' conceptual change using a computer simulation of the human cardiovascular system as an instructional tool. Contains 33 references. (DDR)

This paper describes an instructional method designed to increase opportunities for students to learn and practice appropriate social skills. The strategies for development and implementation of such structured programs of nature-based and animal-based activities are based in part on a pilot program in three urban elementary and middle schools.…
