Describes the nature of the neutron and describes how it was discovered. The interaction of the neutron with other nuclear particles is also discussed. (SK)

Discusses an addition to an apparatus which allows the effect of temperature on a paramagnetic compound to be measured, therefore demonstrating the Curie-Weiss law. The experiment can be used as a demonstration or student experiment to stimulate discussion of magnetic susceptibility and ligand field trips. (Author/JN)

Summarizes the advantages in using the Daedalon Air Table, which supplies compressed air to the pucks instead of the table surface itself. Describes methods for constructing an electronic null detector using a Weston type galvanometer and an integrated circuit operational amplifier. Also describes a redesigned and improved sound-level meter. (CS)

Presents three different procedures in which reagents are added in a specified order to a large beaker containing an aqueous solution of nickel sulfate. Complex ions of nickel (II) are prepared by using aqueous solutions of ammonia, ethylenediamine, dimethylglyoxime, and cyanide ion. (CS)

Different programs have been developed for the simulation of physics experiments by using TI-57 programmable calculators. Two of these programs, describing the simulation of a successive radioactive decay and the random motion of a gas molecule, are presented. (Author/SK)

Describes a slide presentation method for preparing graduate students as lab instructors for engineering courses. The course may not only reduce faculty training time but also provides continuity in quality and content of instruction. (DS)

Describes a systematic investigation of the understanding of velocity by students in introductory physics courses. Data were obtained using the individual demonstration interview, similar to the clinical interview. Results are reported for success of different populations in comparing velocities for two simultaneous motions. Implications for…

Explains how fluctuations of emphases in the economy, job market, and supply and demand for engineers, in the past decade have influenced enrollments in engineering schools, thus creating a cyclical behavior of boom and bust in enrollments, and in the engineering labor market. (GA)

Presents an experiment for inorganic, organic, or physical chemistry students utilizing acid-base titrimetry to study the stoichiometric of a solid state reaction. Time involved ranges from one to three, three-hour lab periods. (Author/SA)

Described are the results of research in chemical education carried out at the University of California, Berkeley. Individualized instructional materials to teach major concepts of stoichiometry to unprepared students were developed and validated. (BT)

Outlines an approach for instruction in a physical chemistry laboratory which combines traditional and project-like experiments. An outline of laboratory experiments and examples of project-like experiments are included. (BT)

Discussed are three aspects of the development of computer-aided learning materials: (1) reconstructing a beginning college physics course to be more efficient and flexible; (2) exploring simulations and learning sequences not usually accessible to students; (3) dissemination of project ideas to administrators and faculty elsewhere. (CS)

To encourage and recognize student academic achievement, the faculty of Natural and Social Sciences, State University College at Buffalo, sponsors a grant program to fund student-initiated research. The program and related projects, including a reception and publicity for achievers, are described. Also discussed are program fund-raising and…

Described is a workshop for graduate students and faculty members that focused on improvement of teaching methods. Topics included were: common weaknesses of inexperienced lecturers, diagnosing teaching weaknesses, elements of a good lecture, creating an atmosphere of participation, Piaget's developmental psychology, behavioral objectives,…

An experiment is presented on the formulation of a negative photoresist. It is intended for use as a fifteen minute classroom demonstration for undergraduate general chemistry students. (SA)
