Described is a Piagetian learning cycle based on Monte Carlo modeling of several simple reaction mechanisms. Included are descriptions of learning cycle phases (exploration, invention, and discovery) and four BASIC-PLUS computer programs to be used in the explanation of chemical reacting systems. (Author/DS)

Described is a diffusion apparatus to be used in an undergraduate physical chemistry laboratory experiment to determine the diffusion coefficients of aqueous solutions of sucrose and potassium dichromate. Included is the principle of the method, apparatus design and description, and experimental procedure. (Author/DS)

Cites recent experiences of the Leeds School Science Industry Liason Committee in organizing contacts between schools and industry. Procedures are discussed for developing kits of teaching materials based upon local industries. (CS)

Describes the tasks of the Industry/Education Unit (IEU), established within England's Department of Industry to deal specifically with changing the attitudes of young people toward industry. (CS)

Provides a coding system, with flow charts, for "Hazchem," which provides an application of the knowledge of chemical behavior to emergency situations. (CS)

Reviews and provides sources for acquiring three filmstrips and one film concerning the following topics: laboratory safety, energy and entropy in chemical reactions, and chemical bondings. (CS)

Describes a competency-based, modular laboratory course emphasizing the synthesis and characterization of polymers and directed toward senior undergraduate and/or first-year graduate students in science and engineering. One module, free-radical polymerization kinetics by dilatometry, is included as a sample. (CS)

Outlines a variety of laboratory procedures, discussions and demonstrations including the preparation and analysis of a square planar copper (11) complex, thermit reactions in a sand mould, product solubility, an aid for learning common oxyanions, thermal decomposition of nitric(v) acid. and nine others. (GS)

Presents arguments for and against the viewpoint that the teaching of chemistry and of physics should fall in line with modern mathematics. Concludes that modern mathematics has been beneficial in some respects and harmful in others. (CS)

Presents examples of combination, decomposition, replacement metathesis, and neutralization chemical reactions. Suggests that students will gain knowledge of some general trends in the chemical properties of the main group and transition elements by examining reaction types. (JN)

Reports the results of a survey of practicing scientists, recent graduates, and undergraduates about their perceptions of undergraduate laboratory programs in biology, chemistry, and physics. Scientists and graduates regard laboratory experiences in pragmatic terms stressing the scientific process skills while undergraduates regard laboratories as…

A method is described for measuring differences in grading that is free from the effects of individual student abilities and teaching quality. The analysis locates teachers on a continuum scale from "hard" to "easy" and enables the identification of possible extremes in grading that might manifest themselves in unfair treatment of students. (JMD)

Reports on the Dreyfus Foundation Conference held in Boston at Northeastern University. The proceedings are outlined and some statistics are presented on the supply and demand for chemistry graduates. (Author/SA)

Presents the procedures involved in conducting a photochemical experiment intended to provide undergraduates with exposure to the synthetic advantages of organic photochemistry. (Author/SA)

Discusses the use of formulae in the teaching of chemistry as part of the individual culture and of the conceptual structure of chemistry. A historical viewpoint on the procedures for structure representation and some educational implications for teaching chemistry in Italy are also presented. (HM)
