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)

Discusses recent approach at undergraduate engineering curriculum emphasizing bringing some engineering courses to freshman and sophomore levels. Summarizes several examples of the approach at various institutions throughout the country. (YP)

Describes a course, "Exercise Physiology and Biochemistry," for nonscience majors attracted to athletics. Outlines the lecture and laboratories combined with the lecture. Provides programs for daily exercise and weight training. (YP)

Describes and analyzes the Nigerian Secondary Schools Science Project which was adapted for use in the school system by the University of Lagos, Nigeria. Found that imprecision and lack of coherence in stating performance objectives led to confusion in interpretation by teachers. (KO)

Discusses pupil misconceptions concerning forces. Summarizes some of Assessment of Performance Unit's findings on meaning of (1) force, (2) force and motion in one dimension and two dimensions, and (3) Newton's second law. (YP)

Describes one teacher's approach to teaching science in preschool and discusses the advantages of experiential learning in preschool science programs. (RJC)

Described are three experiments on the photometric, Gaussian, and image-forming properties of a helium-neon gas laser. Details of the experimental method and typical calculations with diagrams and graphs are provided. (YP)
