Discusses the use of computer-aided instruction (CAI) packages in promoting active student learning. Describes the development of a CAI package that highlights discussion of real engineering cases and students' ability to transfer knowledge to new engineering problems. Concludes that the students' problem-solving skills can be improved with the…

Presented is an analogy that can be used to explain the particle theory of matter. The three phases of matter are represented by preschoolers, yuppies, and senior citizens. The value of using analogies is discussed. (KR)

Described is an interdisciplinary program designed to coordinate the physics and calculus courses for seniors in a Massachusetts high school. Target audience, benefits, team coordination, and impact are discussed. A list of suggested crossover topics is provided. (CW)

The articles in this feature support the view that history and philosophy are useful to science instruction. Topics include the history of science teaching, the role of science textbooks, the relationship between science and the humanities, and a bibliography on history, philosophy, and science teaching. (IAH)

Described is a project designed to give students an understanding of the environmental implications of current energy practices and a chance to participate in a project that may have a measurable impact on environmental quality. Suggestions for the integration of this project into high school science classes are provided. (CW)

Presented are three computer projects: vector analysis, electric field intensities at various distances, and the Biot-Savart law. Programing suggestions and project results are provided. One month is suggested for each project. (MVL)

Presents two demonstrations using the overhead projector: (1) describes how to build a projecting voltmeter and presents uses for the classroom; and (2) investigates the color of fluorescent solutions by studying the absorption and transmission of light through the solutions. (MVL)

Provides explanations of 15 experiments, laboratory activities, demonstrations, and lessons for use in instruction. Includes information on Daphnia, wild garlic, crystals, gas chromatographs, bleaches, alcohols, reactivity series, chemistry formula, electronic keyboards and waveforms, interference and diffraction gravity, Moire fringe patterns,…

Presents information in brief on changing priorities in science education. Cites three categories of aims for science, traits of underachievers, and the processes of science. Includes reflections on the Salter's GCSE Scheme of Assessment, the integration of science and drama, and a historical perspective of practical work in school science. (RT)

Teacher-directed versus student-oriented remediation methods in high school physics classes in Nigeria were compared using 121 fifth-form students. Formative, achievement, and intelligence tests were administered. Teacher-directed remediation treatment enhanced learning and was more effective than was a student-oriented method. (TJH)

Examines the effect of solar radiation on colored shingles. Describes the experimental procedure, results, and discussion. Presents a picture of the experimental arrangement and three graphs of data measured at different dates. (YP)

States that quantitative modelling allows teachers to concentrate more on qualitative understanding. Suggests the main benefits as (1) repetitive calculations are reduced allowing greater attention to be focused on underlying models; (2) more "what if" models can be tested; and (3) a wider variety of data can be used to test models. (MVL)

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)

Examines if a self-paced, interactive microcomputer delivery system can decrease the time needed and improve the level of mastery as compared with a traditional self-paced instructional approach. Uses high school physics students with five activities and reports that no differences were found. (MVL)

Discusses the growth of computer networks in elementary and secondary schools and describes numerous benefits for both instructional and management functions. Topics discussed include ease of use; educational advantages; examples of use in physics, writing, and journalism classes; student records management; cost benefits; and greater efficiency.…
