Presents reviews of audiovisual aids for chemistry including format, time, catalog number, price range, supplies, and reviewer's comments. (SK)

Summarizes results of a three-item questionnaire returned by 43 Michigan institutions expressing views on wearing contact lenses in chemical laboratories. Questions focused on eye protection, type of protection, and use of contact lenses. (SK)

Demonstrates how audiotutorial techniques can be applied to the teaching of more advanced subjects (physical chemistry and electrochemistry), and how this can have significant affect on the overall quality of instruction and the mechanics of teaching the course. Includes a general description of audiotutorial instruction. (SK)

Reviewed are various advantages to the use of videocassettes in chemical education. Common recorders and their accessories are listed and evaluated. (CS)

Reported and tabulated are results from the use of an integrated audiovisual methodology in teaching two different analytical chemistry courses in Venezuela. (CS)

Reviewed are experimental methods (diffraction, spectroscopic, and resonance methods) used to obtain the structural parameters of bond angles and bond lengths in molecules. The valence shell electron pair repulsion theory (VSEPR) is summarized and applied to several real molecules. (CS)

The discovery of a superconducting organic compound is reported. The compound, (TMTSF)-2, has no metal in its composition, and the author believes that it is the precursor of a family of superconducting organics. (Author/SA)

Reviews aspects of quality control (methods to control errors) and quality assessment (verification that systems are operating within acceptable limits) including an analytical measurement system, quality control by inspection, control charts, systematic errors, and use of SRMs, materials for which properties are certified by the National Bureau…

To help students develop career plans, opportunities are provided for self-assessment into an application for one of ten imaginary companies. Basic information is given for each company. During the term, students solve problems written in the context of the company for which they are working. (JN)

Describes a course based on the premise that an automated experiment consists of three distinct sections: experiment, computer, and interface (including both software and hardware). Includes course content, lecture topics, and discussion of necessary computer equipment. (Author/SK)

Describes a simple, inexpensive experiment for extraction of synthetic dyes permitted in foodstuffs, and their separation and identification using thin-layer chromatography and ultraviolet/visible spectroscopy. (Author/SK)

Discusses characteristics of materials and labels used by the Department of Transportation, including label design and color: red (flammable and spontaneously combustible), white/yellow (radioactives), orange (explosives), white (poisons), yellow (oxidizers), green (non-flammable gas), black/white (corrosive), blue (dangerous when wet). Includes…

A flow chart is used to illustrate analytical chemistry as a component of a problem-solving process. Beginning with a problem, the flow chart proceeds to the question, experimental design, experiments, data treatment, answer, and solution. Another flow chart is used to expand on experimental design. (Author/SK)

The increased emphasis on theory in undergraduate/introductory chemistry courses suggests a need for beginning students to understand philosophic aspects of scientific theory. Discusses alternative viewpoints on theory development and how misapprehensions about this can influence student creativity; argues for formal introduction to theory…

A set of ions is selected (by computer program available from author) for each student in this qualitative analysis course. Students work out a separation scheme based on results of their experimentation and using selected references. Course methodology, preparation of solutions/unknowns, grading, and student responses are discussed. (Author/SK)
