Describes the construction of a timer to determine reaction time for use in life science classes. Uses a computer program with a menu that suggests specific experiments. (DDR)

Recommends beginning certain chemistry courses with revision and consolidation of mole calculations. Argues that by choosing examples related to health and safety, mole calculations can be made less academic while raising student awareness of important issues. (DDR)

Describes a laboratory exercise that simulates the spread of an infectious agent among students in a classroom. Uses a modified Enzyme Linked ImmunoSorbent Assay (ELISA) to provide students with experience using an authentic diagnostic tool for detecting human infections. (DDR)

Presents a weeklong earth science module that allows students to explore the relationships between natural and manufactured materials. Relates rocks and minerals in the earth science curriculum to observations students make in their urban and suburban travels. (DDR)

Discusses BioProjects, a new technique for helping students understand the scientific method, in which students formulate a hypothesis, test it, and present the project to the class. States that through biological, quantitative investigations conducted outside of the classroom, BioProjects helps students develop investigative as well as oral and…

Presents a teacher's reflection on his teaching using two different perspectives. The first perspective uses the cognitive apprenticeship metaphor as a tool for analyzing and understanding teaching. The second, a methodological perspective, uses conversational analysis to arrive at microanalytic descriptions and conceptualizations of teaching. (PR)

Three themes emerged from interviews with 149 elementary through secondary students: instructional strategies, cognitive demands, and students' ideas about how science should be taught. Elementary students enjoyed the messing around quality of their activities. Junior high school students were becoming uncomfortable with open-ended activities. In…

Discusses programs and research that support the integration of literature and science. Reviews literature selections across a range of genres that complement topics included in middle school science, including science fiction and poetry. Considers resources educators can use to find additional science-related material. (JPB)

Explains Knowledge Integration Environment (KIE) activities which are designed to promote lifelong science learning. Describes the partnership process that guided the design as well as the Scaffolded Knowledge Integration (SKI) framework that gave the partnership a head start on creating effective materials. (Contains 52 references.) (Author/YDS)

Explains the process of creating a curriculum based on the National Science Education Standards (NSES). Introduces an activity where students experience flowers and their environments. Focuses on Content Standard C of the NSES. (YDS)

Discusses the reform of the middle school science curriculum to engage students in their own development, represent the ethos of contemporary science, recognize social changes and cultural shifts, and assure productive learning, all focused on the welfare of young adolescents. (JPB)

Assesses the potential of multimedia authoring as a learning tool using the software ASTOUND. Investigates the knowledge acquisition caused by a multimedia program among 32 grade 12 students on a multi-disciplinary environmental unit about earthquakes. Provides basic background about earthquakes via laboratory experiments and field trips to…

Examines the views of approximately 60 secondary science teachers and university scientists from three different research projects for insight into issues of gender and ethnicity in science education. Explores the participants' professional and personal identities from the perspectives of nature of science and beliefs related to students'…

Shows how the tobacco mosaic virus can be used in conjunction with the common bean plant Phaseolus vulgaris to provide a discernable, experimental model that students can use to study induced resistance. (Contains 17 references.) (DDR)

Tests a multifaceted curriculum for use in introductory earth science classes from the secondary school to the introductory undergraduate level. Simulates the greenhouse effect with two fish tanks, heat lamps, and thermometers. Uses a hands-on science approach to develop a deeper understanding of the climate system among students. (Contains 28…
