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)

Presents a brief description of the Dutch school system's structure. Describes the most important issues that have contributed to the development of physics education resulting from changes with respect to the physics curriculum, the final physics examination, and stimulation by a Dutch curriculum development project. (RT)

Describes a graduate course designed to teach the noncrystallographer how to read a structure paper critically. The course combines formal didactic instruction with student seminar presentations of specific papers from the crystallographic literature. Includes a course outline. (CW)

Discusses a method to use several diffraction gratings at one time with one hydrogen bulb. Describes the experimental set up, background, and results. (CW)

Describes a purification process through affinity chromatography necessary to obtain specific blood group glycoproteins from erythrocytic membranes. Discusses the preparation of erythrocytic membranes, extraction of glycoprotein from membranes, affinity chromatography purification, determination of glycoproteins, and results. (CW)

Discusses ways in which poetry and etymology can be used to capture and/or convey scientific principles. (JK)

Reports on a study using two alternatives for evaluating the quality of teaching and courses in an undergraduate engineering program. Results indicate that the relationship between a global problem and individual questions is highly correlated. (TW)

Describes an evaluation program which is aimed at providing well-designed, comprehensive, and objective tests to a specific category of engineering students. Involves the use of a computerized statistical analysis. Provides recommendations for organizing such an activity. (TW)

Described are the objectives, schedule and evaluation of an institute. Listed are demonstrations performed illustrating physical properties and physical change, energy changes, and chemical equilibrium. Discussed are the advantages of using demonstrations in teaching precollege chemistry. (CW)

Describes a laboratory experiment designed for use in a freshman chemistry course. Considers the use of a set of known "training reactions" with a "training set" of solutions. (CW)
