Discusses areas of modern astronomy that owe their development largely to nonoptical radiation: radio, infrared, ultraviolet, and x-ray radiation. Indicates new observations favor the big-bang" model of the universe, for it is now established that the earth is expanding at a measurable rate. Annotated bibliography. (LS)

The author sees the physical sciences as processes of inquiry and proceeds to analyze and criticize CHEM Study, CBA, and PSSC physics in terms of their views of inquiry and of the sciences. A discussion of some desirable features for a high school program in physical science is included. Bibliography. (LC)

Traces the major developments in libraries from ancient times and concludes that another major development is overdue--the establishment of an organized body of scientific principles as a foundation for the study of librarianship as an intellectual discipline at first-degree level, for the development of pure and applied research, and for the…

Focuses on the sigmoid growth curve as a biological principle that can be applied to the study of human behavior. (CS)

Discusses two educational issues: the constitutionality of competency-based education and the compatibility between this policy and contemporary scientific thought. The author presents her personal views on competency-based education and discusses the need for educational accountability on the part of teachers and other educational professionals.…

This article is a brief survey of alchemy since the chemical revolution. It shows that the reasonable expectation that alchemy could not survive the new chemistry is wrong, through a description of the work and beliefs of several prominent alchemists. (Author/DS)

Discusses some physical principals that can be used to understand the proper ties of Portland cement and concrete. (HM)

Discusses the existence of matter in smaller groups known as clusters. Applications of the findings in scientific studies are presented as they relate to technology. (SA)

Explores major expectations of Mach's principle concerning motions due to matter in the rest of the universe. (MLH)

Discusses theories about the possibility of the weakening or strengthening of the gravitational constant, and the cosmological effects of such a change. (MLH)

Reports on a study to elicit junior secondary students' understandings of the nature of science (NOS) through peer collaboration instruction based on science stories specifically developed to present several aspects of NOS. Investigates how students reacted to the stories and whether they were able to extract the aspects of NOS presented in the…

Describes a collaborative professional development program, Inquiry-Based Field Studies Involving Teacher-Scientist Collaboration, that uses scientist-teacher teams to improve teachers' understanding of scientific inquiry. Reports that the project allowed teachers to develop a deeper understanding on the nature of science. (Author/YDS)

Uses ideas about nature held by four high school science teachers to illustrate how any abstract notion of a scientific worldview does not adequately describe the perspectives of scientifically knowledgeable individuals such as competent secondary school science teachers. Effective science education helps students develop an understanding of…
