Illustrates the construction of a classroom demonstration of the moving cube illusion. Gives details for building this three-dimensional figure that appears to be a solid cube but is actually a hollow figure. Suggests ways in which this display may be used in the classroom or as a permanent exhibit. (KO)

Reviews various science activities investigating polarized light. (SL)

This article examines the 11-year Soviet experiment with boys' schools as a way to cast new light on scholarly research and public debates about single-sex education. Drawing on archival and published materials by educators who described school conditions, identified problems, suggested reforms, and evaluated remedies, the author argues that…

Directions for constructing a hand glider out of free or inexpensive materials are combined with measurements, tests and recordings of its flight done in metric units. (BR)

These demonstrations stress individual differences, a concept becoming increasingly important in psychological research. Intended for use in undergraduate psychology courses, four demonstrations that illustrate common examples of human variation are described. The demonstrations deal with the following individual differences: taste blindness,…

Stresses the importance of teaching the Greek classics so that they both "speak directly to the student" about matters of importance to modern life and provide an initiation into the ancient ways of life out of which they were written. (Editor)

Uses inexpensive equipment to demonstrate, through factorial design, an interaction between genetics and environment. Provides instructions for introducing and conducting the experiment, reporting that significant results are usually obtained. Notes the exercise is appropriate for experimental psychology, developmental psychology, behavior…

Describes several ways to demonstrate the relationship between various aspects of auditory stimulation and sensation. Discusses the equipment required to hear and to visualize simultaneously a variety of auditory signals. States that these demonstrations allow students to learn more about sensory processing in general and auditory function in…

In an experimental approach to the teaching of General Mathematics, students work individually on projects; two teachers work together with the class. Although evaluation is incomplete, the authors feel the approach has had a positive effect on student motivation. (SD)

Described is a simple demonstration that relates the techniques of magnetic resonance imaging (MRI) used in medicine and nuclear magnetic resonance (NMR) spectroscopy. Included are materials, procedures, and probable results. (KR)

Described is a demonstration that provides an introduction to nonequilibrium reaction-diffusion systems and the coupling of hydrodynamics to chemical reactions. Experiments that demonstrate autocatalytic behavior that are effected by gravity and convection are included. (KR)

Reports on apparatus for generating Lissajous figures, projecting Poisson's spots, photographing diffraction patterns, electric heating, and projecting moving longitudinal waves on an oscilloscope. (SL)

After discussing the objectives and challenges of mathematics courses for preservice elementary teachers, and their instructional implications, the author describes an experimental laboratory-based course. Achievement of those taking this course is compared with achievement in a lecture course. (SD)

Describes an educational experiment conducted at Miami University where graduate cable management seminar students were given hands-on experience in developing programming ideas and producing programs for a cable television channel. Learning objectives, evaluation methods, and faculty and on-site supervisor roles are discussed, and recommendations…

Describes a magic show designed to encourage young children in physics and chemistry. Discusses how a little "razzle-dazzle" can effect children positively. Tells how to organize and perform a magic show. Details six tricks that focus on principles of chemistry or physics. (CW)
