Experimental and theoretical data are presented which verifies the existence of the hydronium ion. This existence was confirmed directly by x-ray and neutron diffraction in hydrochloric acid. Recommended is the abandonment of the erroneous hydrogen ion formulation and names such as proton hydrate. (BT)

This study recalculates outdated values for thermochemical radii using more reliable and elaborate calculations of lattice energy and recently obtained ancillary thermodynamic data. (BT)

Presents a derivation which yields a general relationship between the relaxation time, and equilibrium concentrations and rate constants. (BT)

Presents the Award Address for the 1979 American Chemical Society Award in Chemical Education. Discusses teachers and learning situations which made a difference in the recipients' schooling and the significant attributes of teachers and techniques of teaching that stand out as lessons for would-be teachers. (BT)

Describes a practical, job-related, 3 1/2 month long, basic chemistry course developed by Monsanto Research Corporation to train laboratory technicians and service employees. The course, centered around 31 chemistry topics, is designed to supplement university courses and stresses application of concepts. (BT)

Describes a unit developed to introduce chemical technology students to basic library research using the resources related to chemistry. The unit consists of a lecture on basic library organization, bibliography and abstracting, a lab with hands-on bibliographic searching, and a follow-up independent exercise in research. (BT)

Describes a program developed to expose college chemistry students to some of the more modern information retrieval tools, as computerized online databases. Following classroom lectures and discussions, students individually develop a search statement relevant to their own research needs and run it in the Chemical Abstracts files. (BT)

The following aspects of the radiochemistry program at San Jose State University in California are described: the undergraduate program in radiation chemistry, the new nuclear science facility, and academic programs in nuclear science for students not attending San Jose State University. (BT)

Reports the development of an integrated clinical approach to introductory chemistry education at the undergraduate level for students majoring in nursing and the allied health professions at the University of Lowell. (BT)

Discusses research attempting to identify difficulties experienced by undergraduate chemistry students in performing specific logical operations at the formal level as described or implied by Inhelder and Piaget. (BT)

Describes an attempt to develop and staff a new first-year laboratory course at the University of Jordan. A postgraduate course in chemical education is used as the development and training vehicle. (BT)

Details a summary presented by a distinguished high school chemistry teacher at the close of the symposium on the High School Instruction Interface dealing with the modernization, restructuring, and improvement of chemistry teaching. (BT)

Describes a laboratory demonstration in chemical equilibrium using ferric chloride and ammonium thiocyanate that would serve as a useful basis for an inquiry investigation. (BT)

Presents a detailed discussion on the chemistry of glass. Topics discussed include: natural glass, early history, modern glass composition, raw materials for glass melting, chemically modified glasses, modern glass forming, glass ceramics, and new developments in glass research. (BT)

Describes a chemistry word elimination game that can be used to provide an instructive student activity. (BT)
