A program written for the Apple II microcomputer that plots the "one-S" orbital of an atom is described. The material is used to move from the Bohr model of the atom to the quantum mechanical description. (MP)

Suggesting a distinction between student attitudes toward science as a school subject (SUBATT) and toward the social implications of science (SOCATT), reports results of a study using various measures focusing on SOCATT and SUBATT of approximately 2,200 students in 33 schools, including findings related to sex differences. (DS)

Following a brief introduction to the origin and nature of a course in polymer rheology and melt processing, discusses course objectives, detailed content, teaching strategies, and observations/experiences from its first offering. (SK)

Suggestions for chemistry teachers in their attempts to teach and inspire students are provided. (HM)

Announces the availability of grants from the National Bureau of Standards for the compilation of reliable reference data and the weeding out of faulty data. The grants are in response to the demand for data in all areas of science and technology. (Author/SA)

Describes a solution calorimetry apparatus useful in measuring heats of metal ion-ligand reactions. (SK)

Discusses and simplifies the theory behind Electron Spin Resonance (ESR). Describes applications to radiation chemistry. (CS)

Discusses reactivity of metal ions with the primary products of water radiolysis, hyper-reduced metal ions, zero-valent metal ions, unstable divalent ions from the reduction of bivalent ions, hyper-oxidized metal ions, and metal complexes. (CS)

Discusses the use of steady-state radiation chemistry and pulse radiolysis for the generation of initial free radicals and formation of peroxy radicals in the autoxidation process. Provides information regarding the autoxidation process. Defines autoxidation reactions and antioxidant action. (CS)

Expands the basic concepts regarding the radiation chemistry of simple aqueous systems to more complex, but well defined, organized assemblies. Discusses the differences in behavior in comparison to simple systems. Reviews these techniques: pulse radiolysis, laser flash, photolysis, and steady state irradiation by gamma rays or light. (CS)

Summarizes the technology of the field known as radiation processing, the term used to describe the large scale production or modification of materials by ionizing radiation. (CS)

Describes an interdisciplinary student experiment based upon the radiation effects on polymers, integrating some of the fundamentals of radiation chemistry, polymer chemistry, and material science. Also demonstrates how the information gained in the experiment has direct commercial application in product manufacture or processing. (CS)

Compares two methods for computer generation of tests: question retrieval and question generation. Both techniques are described with specific applications for university teaching. Also evaluates the effects of these methods on student performance. Future developments of computer assisted test construction are also discussed. (CS)

Describes several general high school chemistry activities including: (1) making Christmas glassware, (2) some energy-related activities, (3) some learning activity modules developed by the Unigraph Corporation, and (4) some consumer chemistry activities. (CS)

An approach to the teaching of steady-state recycle calculations is presented. Included are the solutions to two sample problems. (BB)
