Describes a study to evaluate the effect of the Energy Education Curriculum Program as perceived by elementary and secondary classroom teachers. Results indicate that energy education is taught in schools when materials and information are made available to the classroom teacher. (RT)

Presents a computer program for use in teaching ion speciation in soil solutions. Provides information on the structure of the program, execution, and software specifications. The program estimates concentrations of ion pairs, hydrolytic species, metal-organic complexes, and free ions in solutions. (Author/RT)

Discusses the advantages of using discrepant events in elementary school science classrooms in terms of motivation and problem solving skills. Describes the materials, procedures, and reasons behind five discrepant activities. (YP)

Describes five basic concepts, such as displacement, velocity, momentum, force, and moment of force. Discusses an experimental model to improve the intuitive understanding of acceleration in a straight line and a non-linear situation. (YP)

Argues that there are five domains of science education: knowing and understanding, exploring and discovering, imagining and creating, feeling and valuing, using and applying, and not just the two domains of content and process which many people view as being science. (RT)

Evaluates the attributes of a microcomputer software package as a supplement to chemistry instruction. Reports higher scores among the students in a control group. Discovers no significant interaction between treatment and development stage. Discusses several implications for further research. Provides the General Chemistry Test and error analysis…

Presented is a blueprint for restructuring the first two years of the engineering curriculum. Four new concepts for the first two years are discussed: (1) the mathematical and scientific foundations of engineering, (2) fundamentals of engineering, (3) the engineering laboratory, and (4) the professional and personal enrichment program. (MVL)

Uses simple pulse NMR experiments to discuss Fourier transforms. Studies the generation of spin echoes used in the imaging procedure. Shows that pulse NMR experiments give signals that are additions of sinusoids of differing amplitudes, frequencies, and phases. (MVL)

Presents a device to illustrate the concepts of entropy of mixing and the contribution of one term in the Gibb's equation. Notes the device is relatively easy to construct and provides a visual demonstration on diffusion. (MVL)

Examines whether participation in physical experiments together with social interaction with adults and school-mates favor the development of causal knowledge and the understanding of a complex physical subject. Concludes that the treatments can lead students to give up pre-causal explanations and to resort to physical ones. (Author/YP)

Tests in each science area were developed around six laboratory tasks. Students had to plan an investigation, collect and organize data, and formulate conclusions based on calculations and graphs. Over 1,000 students from 32 Ohio schools formed the sample for this study. Data are presented by skill and by task. An analysis for gender and school…

This paper urges educators of deaf students to make a greater effort to teach science conceptually to foster real understanding and produce scientifically literate students. The state of science education in general, and for deaf students specifically, is reviewed. Recommendations stress process-oriented teaching, cooperative learning, and…

A springtime forest probably contains over 100 shades of green. Describes outdoor observation activities that let the children monitor tree and plant growth. (PR)

Provides a set of guidelines and useful examples to help teachers assess the effectiveness of inquiry investigations. The authors focus on seven issues: (1) meaningful and accurate learning; (2) time; (3) cost; (4) safety; (5) level of difficulty; (6) preparation procedures; and (7) science activity resources. (ZWH)

This case study describes 1 teacher's implementation of a modified version of Glynn's Teaching-with-Analogies model with a grade-10 optics class on refraction of light. (PR)
