Reports a study examining the relationship between affect and achievement for grade eight students in Australia (n=390). It was found that affect is related more strongly to previous than subsequent achievement and that much of the common variance can be attributed to students' perceptions of their competence in science. (PR)

Describes the distributed practice technique to review course material. Results of a study to compare distributed practice to massed practice indicated that students using the distributed practice technique scored significantly higher when tested two months after practice was completed. (MDH)

Presents examples of physics as applied to the sport of skiing. Examples examine the physics of sliding, unweighting, ski turning, wind resistance, the parabolic and circular motion of aerial skiers, and the aerial maneuvers of ski jumpers. (MDH)

Reports a study to compare the performance of Australian university students on chemistry questions delivered in two different formats: multiple choice and grid. Concluded that students encounter more difficulties with questions presented in the grid format and that grid questions demand a deeper understanding of the topic. (MDH)

Discusses the rate of fall of a wooden beam or a chimney by examining the fall of a highway lamp pole when it is sheered off at its base upon impact by a vehicle. Provides the mathematical formulas to explain and an experiment to illustrate the phenomenon. (MDH)

Compares the chemistry textbooks used in China's elite schools with those used in other levels. Comparisons indicate that the textbooks differ only in the quantity of material required. (MDH)

Development of two interactive videodisks in space science for middle-school-age children is described, and suggestions for development of affordable and successful interactive products are offered. The first interactive program is a touchscreen exhibit designed for museum use, and the second is a classroom tool for teaching a planetary sciences…

Describes the design of the superconducting bird, a device to demonstrate the phenomenon of superconductivity. Discusses the utilization of the device as an example of a motor and compares it to the toy called the drinking bird. (MDH)

Describes a small-scale study of a course that placed emphasis on context- and activity-based science. The Salters' science course makes use of a wide range of learning strategies. Author concludes that pupils' interest and enthusiasm for school science may be increased through a combination of using pupil's everyday interests and employing a wide…

Describes ideas for applying research from space programs to life science instruction including plants in space, exercise and diet on space flights, environmental advantages from space exploration, and the effects of microgravity on health. Discusses space spinoffs used in medicine including digital imaging processing and the Ingestible Thermal…

In this article, constructivism is examined as an epistemological basis for school science and mathematics instruction. The nature and process of constructing scientific and mathematical knowledge in school settings is also considered. A distinction is made between truth and feasibility, and the implications for science education are discussed.…

Offers an adaptation of Readers Theatre based on nonfiction trade books as an alternative to content area textbooks. Discusses the benefits of nonfiction trade books and of Readers Theatre. Offers guidelines for adapting materials to Readers Theatre scripts. Discusses suggested titles and sample script excerpts for health, math, science, and…

The integration of science and mathematics in the middle school using the topic of meteorology is discussed. Seven selected activities for this approach are suggested. Lists of materials and resources for use in this teaching approach are appended. (CW)

Described is an undergraduate biology course which uses exercises for teaching critical thinking. A line-of-reasoning model is presented. Evidence for the effectiveness of this approach is presented. (CW)

Described are modifications made in a traditional introductory biology course and the resulting improvement in student achievement and attitude. The use of cooperative learning groups is stressed. (CW)
