Describes examples of force in daily living. Discusses some examples of gravitational, internal, external, and centrifugal forces in various situations by using force vectors with diagrams. (YP)

Described is an activity for grades kindergarten through three called "Let's Slide Down the Slope." Shows how to apply mathematics and scientific skills to the sliding demonstration. Provided are the procedures, a list of materials, key concepts, background, and extension of the activity. (YP)

Examined are boys' and girls' achievement from a developmental perspective over the three years of science curricula. Results show the overachievement of girls relative to boys in both chemistry and physics in grades 10 through 12. Discusses implications of the results. (YP)

Examines 11 elementary science texts in terms of conceptual structure and reasoning demands using concept maps. Reports that (1) the conceptual structures vary widely across texts; (2) most of the structures are well defined; and (3) the reasoning demands are above the developmental capabilities of most of primary-level children. (Author/YP)

Explains a technocratic ideology--providing the future leaders of society--as main theme of school science reform. Describes the historical frameworks of interpretation. Discusses the growth and failure of the reform. (YP)

Describes an evaluative study that examined the extent of integration between a school library program and the science program. The discussion covers areas in which cooperative planning and teaching were found to be weak and makes recommendations for improvements in communication, curriculum planning, library collections, and creative library…

Discusses the possibilities of accelerating the rate of cognitive development and describes the design and trial of intervention lessons. Gives preliminary results from one laboratory school indicating that the possibility of accelerating general cognitive development is worth pursuing. (YP)

Investigated were 17-year-old British students' comments on their previous science education. Satisfying science education entails (1) relevance, coherence and continuity; (2) concern for student needs; (3) and practical work such as inquiry activity. (YP)

Evaluates 16 commercially available courseware packages covering topics for introductory physics. Discusses the price, sub-topics, program type, interaction, time, calculus required, graphics, and comments of each program. Recommends two packages in measurement and vectors, and one-dimensional motion respectively. (YP)

Community college anatomy and physiology students participated in a 14-hour study skills class designed to determine the effectiveness of a self-regulated strategy on immediate recall and retention of science knowledge. Results indicated that students who constructed graphic postorganizers recalled significantly more than students who simply…

Presents 10 guidelines for developing performance-based assessment items. Presents a sample activity developed from the guidelines. The activity tests students ability to observe, classify, and infer, using red and blue litmus paper, a pH-range finder, vinegar, ammonia, an unknown solution, distilled water, and paper towels. (PR)

Reviews the work of the Commission on Undergraduate Education in the Biological Sciences (CUEBS) from 1964 to 1972. Suggests that now is the appropriate time to reassess their efforts, to build on their successes, and to use their experience to attack some of the continuing problems facing biology education.

Uses air temperature profiles--a topic taught in beginning meteorology courses--to illustrate the ease of restructuring the teaching/learning environment as a problem-solving mode. Students access real-time information through Accu-Weather's interactive database. Students use the data to answer the question, "What happens to air temperatures…

Eighth graders' ideas about thermodynamics, and their understanding of thermodynamics principles, were assessed before and after they attended a one-semester course on thermodynamics. Results characterized students' views concerning scientific explanations of phenomena, parsimonious versus descriptive explanations, the application of science…

In this article, implications for policy, development, and implementation of educational change are offered, along with suggested directions for research. The author contends that all involved need to work together; they need to develop a holistic view of the system and work with an approach that engages interactive partners in the educational…
