Refutes the view that two capacitors in series with a source of constant voltage carry identical charges. Provides experimental procedures to verify this claim. (YP)

Describes a laboratory demonstration that illustrates principles of miscible displacement and chemical retardation in soils. Discusses how the experimental apparatus can be constructed from readily available materials. (TW)

Describes the practical workup of a multiple choice examination system in electrical engineering. Discusses some of the pedagogical advantages obtained by statistical handling of the data. Provides some examples of items. (TW)

Presented is a classification of polymers according to physical condition. Considered are molecular structure and arrangements. Described are demonstrations using polarized light and the mechanical properties of polymers. (CW)

Provides an annotated list of references on computer-oriented projects. Includes information on computers; hands-on versus simulations; games; instruction; students' attitudes and learning styles; artificial intelligence; tutoring; and application of spreadsheets. (RT)

Presents a model system designed for the electrophysiological investigation of single unit activity in intact anaesthetized animals. Illustrates how information is coded into action potential patterns by sense organs. Uses the ampullary electroreceptor of the brown bullhead catfish as an example. (Author/CW)

Characterizes students who transfer into engineering programs from liberal arts colleges and two-year colleges. Discusses the number of transfers and suggests ways to enhance the success of these students including faculty involvement, articulation agreements, and orientation and counseling programs. (CW)

Discusses a new computer modelling system and compares a teaching strategy that uses computers to explore exponential decay with a teaching method employing the Cellular Modelling System in which the monitoring of a real experiment and the development of a model representing the experiment are done at the same time. (CW)

States that students who simultaneously acquire subject matter concepts and high-level thinking skills are more likely to learn, remember, and be able to apply the concepts. Provides an example for assisting faculty in developing better decision-makers. (RT)

Discusses some of the drawbacks of using a demonstration of the electrolysis of water to illustrate the interconversion between electrical and chemical energy. Illustrates a simple apparatus allowing demonstration of this concept while overcoming these drawbacks. (CW)

Outlines an adaptive framework for the study of plants and their pollinators in which both partners in the ecological relationship are seen as maximizing fitness through efficient use of the other as a resource. Suggests experimental projects to examine the validity of these assumptions giving an evolutionary emphasis. (Author/CW)

Describes the Tardigrada as a group of animals suitable for close study in project work. Gives reasons for their suitability and an illustrated identification key. Discusses possible investigations into the ecology and physiology of tardigrades. (Author/CW)

Contains the annotated bibliographies of introductory books and sections of books, recent introductory articles, more advanced articles, and more advanced books dealing with quasars and active galaxies. (CW)

Discussed are field analyses of data involving paleocurrent directions using a goniometer and special programs for a pocket computer. States that on-site evaluation can provide immediate realization and verification of anomalous results. Includes computer programs and directions for building a goniometer. (CW)

Compares the effectiveness of two instructional models in bringing about a valid understanding of science concepts in prospective elementary teachers. Describes the two instructional models; an expository model and a learning cycle model. Concludes that college students understandings of science concepts may be improved using a combination of the…
