Introduces a method for two-dimensional kinematics measurements by hanging marbles with long strings. Describes experimental procedures for conservation of momentum and obtaining the coefficient of restitution. Provides diagrams and mathematical expressions for the activities. (YP)

Discusses a teacher education program for helping teachers facilitate the development of students' understanding of the nature of mathematics and science and to motivate students' interest. Describes the rationale, courses, delivery format, admissions, and program evaluation. (YP)

Describes management courses for undergraduates and postgraduates and supplementary training methods at the Indian Institute of Technology (IIT). Introduces tasks of the Center for Management Studies created in the Institute. Provides courses of study for Bachelor of Technology, Master of Technology, and Master of Science in the Appendices. (YP)

Investigates the potential for carry-over of prior learning from one scenario to the next at various parts of the hard-soft spectrum in a control engineering context. Discusses hard-soft systems, input-output analysis, law of industrial dynamics, decision-making, developing models, model sensitivity analysis, and educational programs. (YP)

Describes an apparatus that facilitates the quantitative study of fermentation in yeast by allowing simultaneous measurements of fermentation rates in several treatments and a control. Explains a laboratory procedure in which the apparatus is used. Several suggestions for further investigations are included. (Author/RT)

Describes an exercise in which students use a hydrological instrument in an actual field situation to measure stream discharge. (RT)

Reviews current biochemistry, education, and polymer course options found in chemistry programs. Proposes a new core curriculum with 28 semester hours with courses in inorganic, chemical, and instrumental analysis, organic, bioorganic, and physical chemistry. Notes that the new curriculum would better prepare students for the existing employment…

Illustrated is the confusion over centrifugal force in sample problems, diagrams, formulas, and examples. Some recommendations to remedy the situation are suggested. (YP)

This article presents an extended abstract of the summary of a survey of environmental studies programs conducted in 1987 by Disinger and Schoenfeld. Covered are survey procedures, responses, and the status of environmental studies programs. (CW)

Many claims that the standard Science, Technology, and Society (STS) movement has generally neglected one aspect of scientific and quantitative literacy: the evaluation of expert disagreements on technical matters. Described are the limitations of the standard approach, elements of an alternative approach, and examples of the alternative approach.…

Discusses a demonstration of interference phenomena using three sheets of polaroid material, a light source, and a light meter. Describes instructional procedures with mathematical expressions and a diagram. (YP)

Discusses a history exhibit of the American Chemical Society, now on national tour. Focuses on lecture to laboratory, chemistry in early America, the Civil War era, the research model, the early twentieth century, the post-war era, textbooks, and the recent past. (MVL)

Describes the spectrum of process design problems. Suggests a methodology for teaching some concepts used in design, including the types of processes considered and their designs, new tools useful in conceptual design, and a strategy for developing conceptual designs. (YP)

The purpose of this study was to develop a procedure for the evaluation of M-demand of chemistry problems. It was shown that dimensional analysis upon the Neo-Piagetian theory of Pascual-Leone could help science teachers to understand the epistemological basis of their discipline. (CW)

Errors in the teaching of the concepts of Charles's Law are traced back through history to a major French physics text published in 1816. Relevant original sources are quoted and remedies are suggested. Five major criticisms are summarized. (Author/CW)
