Reviews the initiatives taken by six states in promoting precollege Science, Technology, Society (STS) education. Discusses the exemplary efforts undertaken in Florida, Maryland, Michigan, New York, Washington, and Wisconsin. (ML)

Indicates the inadequacies and limitations of traditionally written elementary science textbooks. Offers suggestions and provides examples for teaching more accurately and experientially the nature and process of science. Identifies several sources for enrichment of the textbook. (ML)

Differentiates between the cultural environments of graduating engineering students in Nigeria and North America. Describes the existing curriculum of a bachelor of engineering student in Nigeria. Introduces a proposed curriculum for engineering education in Nigeria which would include a fifth year internship program. (TW)

Questions the use of the Reactivity Selectivity Principle (RSP) by teachers and authors of texts in discussing organic reaction mechanisms. Provides some applications and failures of the use of the RSP, reviews some quantitative aspects of the RSP, and discusses some of the rationalization of the RSP failures. (TW)

Discusses the classification of binary oxides as acidic, basic, or amphoteric. Demonstrates how a numerical scale for acidity/basicity of binary oxides can be constructed using thermochemical data for oxoacid salts. Presents the calculations derived from the data that provide the numeric scale values. (TW)

Differentiates between problems, exercises and algorithms. Discusses the role of algorithms in solving problems and exercises in chemistry. Suggests that very real differences exist between solving problems and exercises, and that problem solving steps can be and should be taught in chemistry education. (TW)

Describes a spreadsheet computer program which can be used with an Apple Macintosh computer to perform a multitude of calculations. Discusses two types of calculations taught in general chemistry. Demonstrates how to use the spreadsheet to calculate mass percent and the formula of a compound. (TW)

Suggests a way to change the role of physics teacher. Discusses the teacher as a coach, reducing anxiety, team cooperation, and a grading system including "forgiving learning" which recognizes student's progress. (YP)

Presents examples to show the ubiquitous nature of geometry. Illustrates the relationship between the perimeter and area of two-dimensional objects and between the area and volume of three-dimensional objects. Provides examples of distribution systems, optimum shapes, structural strength, biological heat engines, man's size, and reflection and…

Explores graph theory and use of topological indices to predict boiling points. Lists three indices: Wiener Number, Randic Branching Index and Molecular Connectivity, and Molecular Identification numbers. Warns of inadequacies with stereochemistry. (ML)

Proposes an educational model for chemistry PhD education that emphasizes productivity and centrality of research. Supports greater development of communication skills and suggests a four-year timeline. Listed is a curriculum usable for most sciences. (ML)

Recommends determining molecular weights of liquids by use of a thermocouple. Utilizing a mathematical gas equation, the molecular weight can be determined from the measurement of the vapor temperature upon complete evaporation. Lists benefits as reduced time and cost, and improved safety factors. (ML)

Reports on the session at the New England Association of Chemistry Teachers meeting on chemistry laboratories in March 1987. Speakers included Leonard K. Nash and Audrey Champagne on values and goals; Howard Ende on regulation; Stanley Smith and Jerry Bell on the uses of computers; and Miles Pickering on the human dimension. (CW)

Describes a molar volume-molar mass experiment for use in general chemistry laboratories. Gives background technical information, procedures for the titration of aqueous hydrogen peroxide with standard potassium permanganate and catalytic decomposition of hydrogen peroxide to produce oxygen, and a discussion of the results obtained in three…

Suggests that the process view of science is flawed. Argues that (1) it is superficial and misleading to portray the method of science in process terms; (2) many of the processes have no special association with science; and (3) there is no evidence that performance is improved. Speaks of the challenge facing science education. (RT)
