Summarizes a simple design algorithm which identifies nested loops of equations which must be solved by trial-and-error methods. The algorithm is designed to minimize such loops, provides guidance to the selection of variables, and delineates the order in which systems of equations are to be solved. Examples are included.

Reports on a content analysis of 14 textbooks on endocrinology. Using thyrotoxicosis as the content maker, the study indicated major differences between books with regard to the information provided and the number of words devoted to the subject. Suggests that medical teachers selecting textbooks be aware of such differences. (TW)

Describes a laboratory experiment that is designed to aid in the understanding of the fundamental process involved in gas chromatographic separations. Introduces the Kovats retention index system for use by chemistry students to establish criteria for the optimal selection of gas chromatographic stationary phases. (TW)

Describes a computer program, "Activation Energy," which is designed for use in physical chemistry classes and can be modified for kinetic experiments. Provides suggestions for instruction, sample program listings, and information on the availability of the program package. (ML)

Suggests preparing displays which include both dynamic and static items to attract observers' attention and hold their interest. Includes instructions for making exhibits related to phenomena associated with Joseph Priestley and Michael Faraday. (DH)

Describes courses designed to develop approaches for teaching engineering concepts, applied mathematics and computing skills to liberal arts undergraduates, and to teach the history of scientific and technological innovation and application to engineering and science majors. Discusses courses, course materials, enrichment activities, and…

Describes curriculum enrichment aimed at giving engineers the background necessary to deal with systems from a holistic point of view. Explains science and society interactions as reasons for implementation of courses in (1) the physiology and psychology of work; (2) law, sociology, technology, and environment; and (3) economic growth and…

Provides background information and reasons for research in evaluation of engineering education sponsored by Petrofina Corporation, Belgium. Describes the purpose, reviews earlier and related work, early project results, Belgian industry's point of view, and a follow-up meeting of university and industry leaders. (JM)

Explains how self-produced software can be used to perform rapid number analysis or number-crunching duties in geology classes. Reviews programs in mineralogy and petrology and identifies areas in geology where computers can be used effectively. Discusses the advantages and benefits of integrating department-generated software into a geology…

Reviews a study that examined the effects of laboratories on the grade performance of undergraduates in an introductory crop science course. Results indicated that students enrolled in lecture and laboratory concurrently did not receive higher lecture grades than students enrolled solely in lecture, but did have higher laboratory grades. (ML)

Describes how a field research site provides grauduate soil physics students with practical field-oriented experiences. Explains the structure of the course and the nature of the course's investigations. Assesses the advantages and obstacles associated with the field research technique. (ML)

Provides an overview of the educational system and the instructional approach employed with earth science education in The People's Republic of China. Reviews the major characteristics of secondary, undergraduate, and graduate programs. Cites representative institutions and explains their earth science programs. (ML)

Describes an interactive, self-prompting BASIC program that can be incorporated in introductory and intermediate hydrology courses. Exlains how the program can be used to evaluate pumping test data and also to calculate transmissivity and storativity values of confined aquifers. The program is written for the IBM PC. (ML)

Describes three microcomputer programs that allow geology students to deform two-dimensional images on a computer screen and then to measure changes in angular relationships. Two of the programs simulate pure and simple shear and the third simulates variations in shear strain that occur in shear zones. (ML)

Describes a visual transparency method to develop the concept of resonance with respect to molecular resonance hybrid structures and partial charge on the atoms of an ion. Discusses the distinction between tautomerism and resonance, and emphasizes clarification of the Lewis structure concept. (JM)
