Examines three errors and learning difficulties found to be typical in general chemistry, gives the source of each problem, and presents a method of correcting each problem. Suggests using analysis of examination errors for the purpose of altering instruction for the improvement of student learning. (CW)

Describes a science activity designed for undergraduate biochemistry classes. Provides background, a list of materials, experimental procedures, and the results of this experiment. (CW)

Presents a practical exercise that enables students to measure flux control coefficients in a metabolic pathway in vitro, to verify the summation property, and to compare the differences in the distribution of these coefficients in different steady states. Discusses background, materials, methods, and results of the activity. (CW)

Announces and presents highlights from a new report from NSF "Proposal Review at NSF: Perceptions of Principal Investigators." This report presents the results of a 1986 NSF survey of 14,000 applicants from academic institutions whose proposals for research support had been awarded or declined during 1985. (CW)

Discusses the use of the FT-IR spectrometer in analyses that were previously avoided. Examines some of the applications of this spectroscopy with aqueous solutions, circular internal reflection, samples with low transmission, diffuse reflectance, infrared emission, and the infrared microscope. (TW)

Illustrates the 29 steps involved in the development of a model of a coordination polyhedron that represents the hexagonal closest packed structure. Points out it is useful in teaching stereochemistry. (TW)

Listed are ways to demonstrate physical and chemical properties of matter and to show electrolysis using an overhead projector. (RH)

Reviews National Research Council's (NRC) book, "Opportunities in Chemistry: Today and Tomorrow." Describes the difference between this volume and the NRC's earlier version, "Opportunities in Chemistry." Discusses the initial circulation of the new volume. Indicates how to obtain the new volume. (CW)

Provides coverage of 1987 American Chemical Society's (ACS) public celebration in schools and communities nationwide. Covers the wide variety of activities that were held. Lists important organizations and personalities that were involved. Suggests how to inform the local ACS office of local activities that were held. (CW)

Describes a technique to improve the adaptation, development, and utilization of laboratory worksheets. Two sample worksheets (on decomposition of ethanol and on solubility of potassium chloride) are included. (JN)

Contains a reading list of articles published in 1985 covering 14 biological topics. Includes descriptions, procedures, and references for 26 experiments. These investigations deal with selected concepts in biology, ecology, chemistry, and physics and include computer-based instruction. (ML)

Describes a chemistry "trail" (similar to a nature trail) which focuses on chemical phenomena in the environment. The trail includes 20 stops in and around a local school. Types of phenomena examined include building materials, air pollution, corrosion of metals, swimming pools, and others. Additional activities are also suggested. (DH)

Presents an open-ended experiment which has students exploring polymer chemistry and reverse osmosis. This activity involves construction of a polymer membrane, use of it in a simple osmosis experiment, and application of its principles in solving a science-technology-society problem. (ML)

Discusses theory of thermodynamics of the equilibrium in solution and dissociation-dimerization kinetics. Describes experimental procedure including determination of molar absorptivity and equilibrium constant, reaction enthalpy, and kinetics of the dissociation-dimerization reaction. (JM)

Explores parallels between new paradigms in the sciences, particularly quantum physics, chemistry, and biology, and new paradigms in reading and literary theory, particularly a socio-psycholinguistic, semiotic, transactional view of reading, and a transactional view of the literary experience. (HOD)
