Theoretical background, experimental procedures, and analysis of experimental results are provided for an undergraduate physical chemistry experiment on electron paramagnetic resonance (EPR) linewidths. Source of line broadening observed in a spin-spin exchange process between radicals formed in aqueous solutions of potassium peroxylamine…

Describes an approach to quantum mechanics exploiting the periodic structure of the elements as a foundation for the quantum theory of matter. Indicates that a quantum chemistry course can be developed using this approach. (SK)

Discusses whether chemistry should be taught using a purely descriptive approach or using the current "principles" approach. Considers what sort of background should be provided given the uses students are most apt to make of their general chemistry training. (SK)

Analyzed are university instructor behaviors in introductory and advanced level laboratories of botany, chemistry, geology, physics and zoology. Science Laboratory Interaction Categories--Teacher (SLIC) was used to assess 15 individual categories of teacher behaviors in the areas of questioning, giving directions, transmitting information,…

Summarizes current trends in the number of BS, MS, and PhD graduates of chemical education programs on a nationwide basis. The data are from the report of the American Chemical Society's Committee on Professional Training. A halt in the decline of PhD graduating chemists is reported. (SA)

Provides information on the financial support of scientific research in Austria, including comments on the training, employment, and future activities of chemists in this country. (Author/JN)

Presents an overview of the university fleet, its purpose, relationship to the rest of the United States oceanographic research fleet, history, cost factors, and other information. (DC)

Presented is the full text of the 1980-1981 report of the American Chemical Society's Committee on Professional Training which provides information on chemistry and chemical engineering programs and graduates (bachelors, masters, doctorates) of different universities. Includes list of 1980-1981 degrees awarded by approved schools. (DC)

Presents viewpoints of scientists and postdoctoral students on issues involving the commercial applications and ventures related to recombinant DNA research. Suggests that how universities deal with issues could impact future school/business relationships as well as the future conduct of basic research. (SK)

Reviews identified learning problems dealing with stoichiometric calculations. Suggests solutions to these problems along with consequences for the curriculum. Includes remarks from a mathematics teacher concerning these problems. (DS)

Discusses a one-semester course on recovering fossil fuels and minerals from underground formations. Includes course outline and information of its major divisions: (1) Geological Background; (2) Flow, Transport, and Interfacial Phenomena in Porous Media; and (3) Description of Underground Processes. (SK)

Reviews an elective course designed to incorporate: (1) study of operating methods for adsorption, chromatography, and ion exchange in a pattern set by the instructor; (2) study of student selected topics with instructor developed lectures and assignments; and (3) course project done by each student. (SK)

Two computer-oriented chemistry laboratory simulations are described. The material focuses on acid-base titration and an ideal gas simulation. (MP)

Described is a study that confirms positive effects on student achievement of manipulation of molecular models by high school chemistry students over a long period of time. Also examined but unanswered were questions regarding applications of Piaget's theories in determining differential effects for concrete and formal operational students. (CS)

A physics teacher describes the learning environment of an independent day school in Oklahoma. Emphasis is directed towards the science and mathematics curriculum and the teacher's responsibilities in teaching and advising the young people. (SA)
