Discusses seven-coordinate complexes of the first-row transition metals. (SL)

Reviews Piagetian concepts, the identification of student cognitive level of development, and chemistry instruction. (SL)

Discusses instructor considerations to be made concerning student cognitive development in preparing and teaching introductory chemistry. (SL)

Presents a method for demonstrating Seebeck, Peltier, and Thomson effects in a single experiment. (SL)

Describes a cooperative program in physics between Stanford University and community colleges within a one hour driving distance of Stanford. (SL)

Reports that allowing senior physics students at the Technion, Israel Institute of Technology, to substitute an experiment in teaching physics to an eighth grade class for one three-week laboratory experiment provided stimulating experience for students, pupils, and teachers, and changed some student career goals. (SL)

Discusses the calibration of bolometric and photoelectric devices utilized for the measurement of solar energy. (SL)

Discusses the need of introducing corrections due to wire stiffness arising from end constraints and wire axis distribution curvature in the measurement of ac electrical frequency by exciting transverse standing waves in a stretched steel wire. (SL)

Reports cost and academic achievement differences between a traditional course and a Personalized System of Instruction (PSI) fluid mechanics course taught at San Jose State University. The PSI course cost 7.3 percent more than the lecture course; grades were 48 percent higher on a 4 point maximum scale. (SL)

Provides an outline for a semester course in the history of organic chemistry. (SL)

Describes a follow-up study of all engineering graduates of McNeese State University since 1961. Reports that the data obtained were useful in preparing for accreditation and in structuring the ongoing engineering program. (SL)

Proposes that a resident engineer program would be an effective way to prevent a future decline in the quality of engineering graduates. (SL)

Discusses the Fermilab summer program for minority students, its evolution, selection of student participants, selection of student assignments, living arrangements, salaries, and the impact of the program. (SL)

Presents an apparatus for demonstrating two-dimensional random motion suitable for illustrating molecular phenomena. Three specific uses are presented. (SL)

Describes an experiment for estimating the half-life of thorium-232. (SL)
