Discusses a National Research Council report which summarizes what laboratories need to know about Environmental Protection Agency and Department of Transportation regulations that apply to laboratory waste. The report provides guidelines for establishing and operating waste management systems for laboratories and gives specific advice on waste…

Discusses the use of property diagrams as an instructional tool to help students understand and visualize important, complex thermodynamic relationships. Also discusses the approach used in preparing these diagrams, which were computer-generated as part of graduate students' research. (JN)

Reviews various spectroscopic techniques currently used to analyze real physical surfaces that bound two actual phases. Problems inherent in analyzing these surfaces and possible approaches that may be taken are considered. (JN)

Proposes an approach to teaching analytical chemistry and chemical analysis in which a problem to be resolved is the focus of a course. Indicates that this problem-oriented approach is intended to complement detailed discussions of fundamental and applied aspects of chemical determinations and not replace such discussions. (JN)

Describes a series of challenges related to areas other than the knowledge content of a course to achieve a similar goal. These challenges are designed to teach not only analytical skills but also such process skills as organization, record keeping, report writing, cooperation with fellow workers, and resolution of discrepancies. (JN)

Discusses issues related to teaching about orbitals in beginning chemistry courses. Lavoisier's rule, Lewis's orbitals, Pauli's principle, the physics related to chemical concepts are examined. The American Chemical Society's Committee on Professional Training's position on these issues is briefly addressed. (JN)

Describes three strategies used in chemistry teaching: (1) chemistry by extension, a reading program in which students write four papers each year; (2) chemistry related to humanities; and (3) chemistry by analogy. Examples of analogies used are provided in the latter description. (JN)

A five-week course for fourth- and fifth-grade students (titled "Chemistry for Kids") was developed. Each class session consisted of a brief lecture, a demonstration, and one or more experiments. An outline of concepts fostered, instructional strategies, and procedures used is provided. (JN)

Discusses a strategy used to incorporate value-related issues into introductory chemistry. Indicates that the approach, necessarily limited to few topics each year, encourages students to reflect on the causes and effect of science-related social issues and to define their personal values. (JN)

Surveyed dietetics directors (N=186) and biochemistry instructors (N=153) on topics emphasized in biochemistry courses for dietetics and nutrition students. Results indicate a consistent pattern of variation in topics emphasized and that this variation is influenced by whether students in other major fields are also in a course. (JN)

Discusses the brief history of microcomputers, offering some predictions about hardware trends. Gives explicit criteria for judging a computer language and discusses different programing languages in terms of what has been used in the past, and why, and what might be appropriate for the future. (JN)

Advantages and disadvantages of using multi-image or lap-dissolve (LD) slide techniques in large lecture sections are discussed. Production, use, and evaluation of LD programs are also discussed. Indicates that these programs are an effective way of improving instruction on visually oriented topics. (JN)

Reports on a project in which observations of student and teaching assistant behavior were used to redesign a teaching unit on recrystallization. Comments on the instruction manual, starting points for teaching the unit, and list of objectives with related tasks are included. (JN)

Describes an experiment in which students become familiar with the organic chemistry extraction process, perform analyses by thin layer and column chromatography, and use the absorption spectrum (obtained from a spectrophotometer) for identification. List of materials needed and procedures used are provided. (JN)

Suggests that pseudophase liquid chromatography, which uses aqueous surfactant solutions instead of organic solvents for the mobile phase, can be substituted for thin-layer chromatography in the introductory organic course. Outlines the method as it applies to common separations in the laboratory. (JN)
