Describes the phenomenological and microscopic aspects of solid-state diffusion in an electric field and presents a Monte Carlo method which is used to stimulate an atomistic model of diffusion in an electric field. The Nernst-Einstein relation is also discussed. (HM)

A discussion is given of the ways in which thermal conductivity, velocity, and viscosity of sound propagation of gases can be measured by freshmen college students. (Author/SA)

The use of microcomputers in the undergraduate chemistry laboratory is presented. Examples are included which can be implemented in the PET 2001. (SA)

Describes various experiments which high school students are preparing, to be carried on NASA's 500 or more Space Shuttle flights in the 1980s. The project is intended to stimulate superior secondary school students. (SA)

Described is a one-week summer chemistry workshop held at Lebanon Valley College, Annville, Pennsylvania, for secondary school students. Experiments and evaluation results of the workshops are provided. (HM)

Describes the details of constructing, and use of, a solar collector. Uses a black liquid to absorb the energy, the thermosyphon effect to drive the liquid through the collector, and a floodlamp as a surrogate sun. (GA)

The Springs task, an individually administered measure of ability to criticize and control experiments, is described. The task has characteristics similar to Inhelder and Piaget's Bending Rods task; it yields scores on naming variables, controlling variables, and analyzing experiments. (See also RIE: ED 163 092.) (JKS)

Describes a spot test experiment, designed for use in the undergraduate laboratory, that has been adopted to follow the progress of coupling reactions. (BT)

This paper, presented at the conference on the role of the laboratory in physics education, which was held in Oxford, England in July 1978, describes the role of the laboratory in school and university physics in Honduras. (HM)

This paper, presented at the conference on the role of the laboratory in physics education which was held in Oxford, England in July 1978, discusses whether physics laboratories are essential or merely desirable for secondary schools and universities. (HM)

Explains the unique benefits of using simulation software in place of physical experiments testing in high school science. Supplies detailed examples of students' usage. A sidebar presents vendors of simulation packages. (AEF)

Explored the impact of regular reading of selected children's books in Slovenian preschools on the development of language competencies among 4- to 6-year-olds. Found significant differences in receptive language, expressive language, and storytelling between children exposed to 2 selected books per week over 2 months and those exposed only to the…

Expresses the importance of scientifically based research in education reform and explains how to judge the validity of educational research. Describes control groups, randomized and matched experiments, statistical educational significance, sample size, and the difference between scientifically based and rigorously evaluated research. (Contains…

Described is a curriculum for a pathology class offered to eleventh and twelfth graders. Included are suggestions for laboratory activities and student projects. These activities can be incorporated into other science classes. (KR)

Discussed are facts about tort liability in science education and strategies that can be used to avoid liability. Variables such as maturity, size, age, mental capacity of students, and the nature of the activities are addressed. Included are four cases in which teachers were held liable for accidents. (KR)
