The heart of learning chemistry is the ability to connect a compound's structure to its function; Lewis structures provide an essential link in this process. In many cases, their construction is taught using an algorithmic approach, containing a set of step-by-step rules. We believe that this approach is in direct conflict with the precepts of…

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)

Explores the current images that students have of scientists, student perceptions of science study in school, and student awareness of their use of science outside of school. Fifth grade students (N=117) were the subjects of this study that asked students to sketch scientists and school science. (DDR)

Draws from studies in the sociology of scientific knowledge to create a new perspective for understanding school science. Merges ethnography and discourse analysis to study science-in-the-making in a physics classroom. Investigates local conceptual ecologies. Contains 55 references. (DDR)

Describes a study in which secondary students (N=32) were interviewed to determine their understanding of the nature of scientific knowledge. Presents some of the strengths and weaknesses of these views and provides cross-cultural comparisons. (DDR)

Reports on a study that used high school students to test the assumptions of the multiple hypothesis theory posited by Lawson to explain the essence of scientific reasoning. Contains 19 references. (DDR)

Argues that students are conditioned by years of multiple-choice testing to use only simple recall and view knowledge as an uncataloged museum full of independent facts that are collected, recited, and left to gather dust. (DDR)

The purpose of this study was to investigate teachers' perceptions of the instructional role of the history of science and their actual practices of teaching science from an historical point of view. Specifically, this study is intended to answer the following research questions: to what extent do science teachers agree with the proposed…

Reports on a case study that is part of a larger study taking place in Trinidad, West Indies. Focuses on one subject and how a person makes use of conventional science and traditional knowledge in everyday life. Contains 29 references. (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)

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)

Addresses the question of what bearing the nature of educational theories has on their application to practice and focuses on the application of normative goal-directed theories of science education. Contains 40 references. (DDR)

In response to an article in the same issue by Norris and Kvernbekk, argues that the theory of Driver and associates, elaborated upon in the three articles which form the basis for their analysis, is not a normative goal-directed theory. (DDR)

Argues that scientific knowledge in school is a social construct in which curriculum proposals are simply points of departure that are transformed by the social interaction that takes place within the classroom. Considers discourse as playing an important role in knowledge construction. Contains 31 references. (DDR)
