Identifies a trend in analytical chemistry toward greater use of instruments and a need for an understanding of the basic principles involved in instrumentation. This need can be fulfilled using homebuilt equipment; examples are provided in the areas of electrolytic conductance and electronic coulometry. (GS)

Presents information about new apparatus, equipment, and literature. Equipment includes such things as an educational computer, computerized analyzer, gas chromatograph, and laboratory extruder. New literature includes catalogs and pamphlets presenting technical data and procedures in areas such as water analysis, titrimetric procedures and…

Proposes an attack on the world food problem which includes the realization that we can eliminate hunger and starvation, the recognition of food as a world currency, and the recognition of the role of chemistry in the improvement of food production, distribution, and preservation. (GS)

Attributes learning difficulties in introductory chemistry to the thesis that many students have not reached the formal operations level of intellectual development. Cites instances to support this thesis, outlines an instructional procedure to overcome the difficulty, and presents a list of competencies that can be expected of these students. (GS)

Explains two approaches for stimulating the intellectual development of the student from the concrete to formal operations level. One method involves experimentation and critique during which the student deduces the principle. The second involves a lecture approach that utilizes the creation of the discrepant event. (GS)

Describes an introductory chemistry course for non-science majors with poor backgrounds in mathematics and English. The course goal was to develop an appreciation of the importance of chemistry to everyday life experiences and to the major area of the student. (GS)

Describes exercises using simple ball and stick models which students with no chemistry background can solve in the context of the original discovery. Examples include the tartaric acid and benzene problems. (GS)

Examines the task of adding historical perspective to the structure of chemistry while teaching the basic chemical knowledge associated with a high school course. Suggested instructional methods include a biographical approach with a newspaper article format, a storytelling technique, and a detective approach. (GS)

Describes an approach which begins with observations and systems familiar to the student and proceeds to develop and test models to explain them. Experimental topics include Brownian motion, a germinating cell, phase change of p-dichlorobenzene, extension and contraction of rubber, and an enzyme system. (GS)

Describes a series of experiments which provide excellent evidence for different degrees of dissociation of a series of complexes and precipitate. The series is based on the copper ion as the acid and sample data are provided. (GS)

Describes an experiment designed to augment textual materials conducive to the inquiry approach to learning. The experiment is the culminating experience in a series designed to illustrate the fundamental nature of the atom: its quantized energy nature, its electrical nature, and its combining ability.
