Discusses revisions in general chemistry laboratory to include group project work. Describes evaluation techniques and sample projects. (MKR)

Describes some key events at the Centennial Meeting of the American Chemical Society and reflects on major chemical discoveries of the last 100 years. (MLH)

Discusses fossilization as a topic involving chemistry, geology, and biology. Describes the processes of silicification and pyritization. (MLH)

Discusses an instructional method that uses a videotape-telephone system to teach graduate level courses to students working in industrial locations up to 250 miles from the main campus. (MLH)

Describes a method of identifying students who are poorly prepared for freshman chemistry, and a preliminary chemistry course designed to prepare such students for the standard chemistry course. (MLH)

Presents demonstrations on (1) ion exchange (softening hard water) and (2) vapor pressure measurement. (RH)

Presents four questions (and provides answers) related to biology and chemistry. Items are concerned with genes, sodium transport, osmosis, and early earth history. (RH)

Discusses the objectives and classroom management of IAC (Interdisciplinary Approaches to Chemistry) modules designed for individualized, self-paced instruction in secondary school chemistry. (MLH)

Describes a study showing that the results of a practical laboratory examination correlated more positively with written examination scores than the teaching assistant's evaluation of laboratory technique. (MLH)

Describes a set of laboratory experiments designed for a chemistry course revised for non-chemistry students. (MLH)
