Critiques the "energy circus," an approach to the introduction of ideas of energy transformation and conservation which is in common use in secondary schools. Identifies some practical and conceptual difficulties and outlines an alternative approach used in introducing ideas about energy using real devices and arrow notation. (CW)

Contains the annotated bibliographies of introductory books and sections of books, recent introductory articles, more advanced articles, and more advanced books dealing with quasars and active galaxies. (CW)

Reports on a study which investigated the effect of instructional objectives on seventh grade students' attitudes toward science. Results indicated that students in the integrated science program had better attitudes than those receiving traditional instruction. (TW)

Describes an attempt to ascertain the validity of the assumptions of the developers of a technology-based biological curriculum. Considers the organization of its learning materials and the transfer of key concepts. Illustrates some of the crucial issues faced by scientific curricula emphasizing technology. (CW)

Studies the quality of graduating science education majors at Brigham Young University (BYU) and attempts to identify possible trends in the ability of students who entered secondary school science teaching. Concludes that there was no manifested trend toward lower quality college students entering the science teaching profession at BYU. (CW)

Describes how a series of models can be constructed to illustrate the structure of eukaryotic chromosomes, emphasizing the structure of DNA. Suggests that by adapting a different scale for each series of models, a complete picture of the complex nature of the chromosome can be built up. (TW)

Traces the development of environmental education in Scotland. Describes the interdisciplinary efforts that have taken place in both elementary and secondary schools since 1974, noting the integration of environmental topics and concepts into various subject areas. Urges Scottish schools to further infuse environmental education into the…

Presents the results of a survey of high school biology teachers in Ohio. Indicates that Ohio biology teachers are far more likely to support the teaching of evolution, and less likely to support the teaching of creationism, than is the general public. Includes the questionnaire in the appendix. (TW)

Describes a program in which teenage students serve as the explainers of the displays in a museum. Reports on a study designed to determine whether such programs can significantly affect students' social development, their attitudes toward science, and their interest in science, teaching, and museums.
