Presents the case for the use of bogs as ideal sites for hundreds of interdisciplinary lessons that combine chemistry, geology, various branches of biology, and wetlands archaeology. Includes general guidelines to aid in the design of interdisciplinary bog studies. (DDR)

Presents the results of a survey on volcanism completed by secondary students (N=1000) in Northern Italy. Findings indicate that these students, who live in a non-volcanic area, firmly believe that their area is volcanic. (DDR)

Outlines a workshop for teachers that illustrates a method of extracting DNA and provides instructions on how to do some simple work with DNA without sophisticated and expensive equipment. Provides details on viscosity studies and breaking DNA molecules. (DDR)

Describes a radiation experiment developed to complement a new environmental chemistry laboratory curriculum. A scintillation counter is used to measure radon in water. The procedure relies on the fact that toluene will preferentially extract radon from water. Sample preparation is complete in less than 90 minutes. Because the level of…

This paper advocates a philosophy of science teaching that embraces intellectual conflict, suggesting that it is important to engage students in productive intellectual conflict in order to teach for conceptual change. Presents two approaches that could actualize the philosophy of "teaching the conflicts" within science instruction. (SM)

Focuses on the gap between research findings and implementation of the results into science teacher education programs, curricula, and professional practices. Addresses one implementation issue that needs to inform future research, teacher education, professional development, and classroom instruction: How views of science, learning, discourse,…

Analyzes the science frameworks of 49 states and the District of Columbia to determine the emphasis given to evolution in these documents at the middle and secondary levels. Collectively, the 50 frameworks emphasized evolution in a manner that suggests that if the public's support for standards-based curricula is a reality, the study of evolution…

Comments on Fensham's suggestion for a change of driver for developing new curricula in school science. Discusses the support needed for a curriculum driven by societal experts, unintentional contributions to the existing problem, and a personal research agenda. (Author/YDS)

Offers a psychological role that external representations can play in the process of refining intuitive ideas into scientific knowledge. Presents an argument for this role through historical analysis of Galileo's ramp experiments, then through documentation of an innovative 6th grade classroom activity. (Contains 19 references.) (Author/YDS)

Presents research on gifted children in primary science. Discusses the implications of the research for the identification of students gifted in science and for preparing a successful science curriculum for these students. (DDR)

Documents the process of building a classroom for environmental education studies. Describes an experiential program that the classroom supports. Provides insight into the integration of subject areas. (DDR)

Uses examples of rich tasks that are linked with traditional science curriculum topics to demonstrate how teachers can come to a better understanding of how to teach topics in context, how rich tasks help build student understanding, and what opportunities exist for making connections within and between topics and disciplines. (Author/YDS)

Describes a science learning program sponsored by the State University of New York College (SUNY) at Geneseo which brings together elementary students, parents, and university students and faculty for an evening of fun, meaningful science experiments, demonstrations, and activities. Includes sample activities. (KHR)

Uses self-report data from school contexts to cluster participating (n=33) senior high school biology teachers in Harare, Zimbabwe according to their own perceptions of the contextual circumstances of their schools. Reports that in theory lessons, teachers from the self-perceived better-resourced schools used less individual organization and less…

Described is the need to incorporate the concepts and applications of advanced composite materials into existing chemical engineering programs. Discussed are the justification for, and implementation of topics including transport phenomena, kinetics and reactor design, unit operations, and product and process design. (CW)
