Yale University intends to issue a statement of policy governing the nature and extent of university and faculty involvement in the commercial application of scientific research. Highlights of the policy statement and issues related to faculty involvement with profit-oriented companies and conditions of grants and contracts are discussed.…

Traces the history and development of temperature scales which began with the 17th-century invention of the liquid-in-glass thermometer. Focuses on the work of Olaf Romer, Daniel Fahrenheit, Rene-Antoine de Reamur, Anders Celsius, and William Thomson (Lord Kelvin). Includes experimental work and consideration of high/low fixed points on the…

Describes development of microcomputer-controlled gamma scintillation spectrometer and chromatographic data analyzer, including design and construction of interface electronics and production of software. Includes diagrams of electric circuits and project evaluation indicating that both instruments functioned as intended. (JN)

Introductory college biology students (N=101) reported frequencies of 20 overt, in-class teaching behaviors and rated the instructor on 12 measures of teaching effectiveness. Moderately strong relationships were found between student perceptions of "information-transmitting" behaviors and achievement, while generally stronger…

Discusses the uses of talk in science classrooms in general and physics classrooms in particular. Presents examples from three physics lessons illustrating the issues raised, focusing on the use of thematic systems of science--ways of talking about particular phenomena. (Author/JN)

Describes the International Organization for Chemical Sciences in Development's (IOCD) activities and programs in applying chemistry to the economic, social, and scientific needs of developing countries. The fundamental aim of IOCD is to assist chemists in developing countries exploit their indigenous natural resources and overcome their…

Provides an annotated list of technical and nontechnical astronomy books (reviewer's remarks, cost, publisher's name/address). Topics include general astronomy, general astronomy textbooks, solar system, amateur astronomy, astronomy history, archeoastronomy, space exploration, related physics books, pseudoscience, and others. (JN)

Discusses the meaning of Schwab's "substantive structures" of a discipline in terms of science philosophy. Presents three techniques for representing substantive structures and discusses some of their uses in science education research. (SK)

Highlights current U.S. research and development (R&D) efforts, focusing on sources of funds (chief federal supporters being Department of Health and Human Services and National Science Foundation), who spends them, and how they are divided among basic and applied R&D. Includes human resources (scientists and engineers) trends (Author/JN)

Discusses who takes college-level courses on solar energy; what material should be covered; sources of texts, outlines, curricula, and teaching aids; kinds of equipment needed; and science-, business-, and vocationally-oriented programs to prepare for such solar energy careers as design, research, education, and construction. (Author/JN)

Describes the life cycle, reproduction, and various classroom uses of the Louisiana Red Swamp Crayfish. Includes advantages and disadvantages of two different culturing techniques. (JN)

Provides procedures for demonstrations: (1) the ferrioxalate actinometer, which demonstrates a photochemical reaction; and (2) the silver mirror, which demonstrates the reduction of a metal salt to the metal and/or the reducing power of sugars. (CS)
