Various aspects of chemical equilibrium were discussed in six papers presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982). These include student problems in understanding hydrolysis, helping students discover/uncover topics, equilibrium demonstrations, instructional strategies, and flaws to kinetic…

Forty-five "poster session" papers presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982) are highlighted. These papers focused on computers in chemistry and chemical education (emphasizing programs) and on instructional innovations (including courses, teaching methods, testing, experiments, and others). (JN)

Highlights four workshops held at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982). Workshops focused on microcomputer tools for chemists, writing software for microcomputers, Project SERAPHIM instructional computer programming contest, and preparing three-dimensional photographs of models and structures. (JN)

Anxiety reduction strategies (lasting 2.5 hours) were incorporated into chemistry laboratory sessions to reduce anxiety and increase academic performance. Treatment enabled students (N=23) to recognize and talk about their chemistry anxieties and experience relaxation techniques. Results showed that treatment significantly lowered level of…

Discusses a successful program in which University of Calgary science/engineering departments offer high school students the opportunity to work on a research project under guidance of a faculty member. Includes history and benefits of the program, selection of students, project work, and orientation/seminar days. (Author/JN)

Highlights seminar which addressed education of the nonmajor. Following brief comments on plan/execution of the seminar program and Japanese system of education, 19 recommendations are outlined and summarized. Recommendations focus on various aspects of courses, curricula, instructional strategies, and other factors related to nonmajors in the…

Describes a forensic-oriented, college-level course in consumer chemistry. Includes course goals, topical outline, and list of chemical ingredients in consumer products useful for student research projects. The first section of the course focuses on mathematics since students in introductory courses may fear doing the most rudimentary mathematical…

Selected aspects of a self-paced chemistry program are described. These include student selection, supervision requirements, and grading indicating that student selection is the key to a successful program. Also points out that quality/quantity of learning (determined by testing) is comparable to traditional lecture courses. (Author/JN)

Three models used in teaching crystallography/mineralogy at the University of Technology (Papua, New Guinea) are described. These include stereographic projection model, optical indicatrix models for Istropic/Anisotropic minerals, and model showing effect of anisotropic minerals under crossed polars. Photographs of the models are also included.…

Eleven computer/calculator programs (most are available from authors) are described. Topics include visualizing molecular vibrations, dynamic nuclear magnetic resonance spectra of two-spin systems, programming utilities for Apple II Plus, gas chromatography simulation for TRS-80, infrared spectra analysis on a calculator, naming chemical…

Written at the student level, wave functions in a single dimension are discussed. Wave functions considered included: (1) linear; (2) wiggle-functions; and (3) dying exponentials. (JN)

Discusses how, in some circumstances, a two-body reaction (association in absence of a third body) is the only possible association, and how reactions proceed in this case. Taking competition between two/three-body reactions into account, considers relative importance of such combinations and conditions under which the former can be competitive.…

Carbon Monoxide obtained from coal may serve as the source for a wide variety of organic compounds. Several of these compounds are discussed, including phosgene, benzaldehyde, methanol, formic acid and its derivatives, oxo aldehydes, acrylic acids, and others. Commercial reactions of carbon monoxide are highlighted in a table. (JN)

An apparatus is described in which effects of pressure, volume, and temperature changes on a gas can be observed simultaneously. Includes use of the apparatus in demonstrating Boyle's, Gay-Lussac's, and Charles' Laws, attractive forces, Dalton's Law of Partial pressures, and in illustrating measurable vapor pressures of liquids and some solids.…

Describes an inexpensive tensiometer, a balance consisting of a plastic drinking straw as the crossarm, a needle as a pivot, and wire loop counter balance to assure proper balance. The instrument permits the quantitative demonstration of interfacial tension and effects of various agents that modify it. (Author/JN)
