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…

Discusses electricity's documented effects on the human body, including both the dangers to human health and the medical application of electrical stimulation to heart problems. Discusses the teaching of such physics topics to potential medical students. (TW)

Discusses the need for student experiments involving the complete characterization of "unknown" inorganic compounds. Describes a project employing a complex metal compound. The compound contains six different components in both inert and labile complexions. Outlines the complete procedure and the preparation of the unknown compound. (TW)

Discusses the difficulties that beginning chemistry students have in understanding acid-base chemistry. Describes the use of conjugate acid-base charts in helping students visualize the conjugate relationship. Addresses chart construction, metal ions, buffers and pH titrations, and the organic functional groups and nonaqueous solvents. (TW)

Discusses some of the federal and state engineering research initiatives that have been launched in recent years, including the National Science Foundation's Engineering Research Centers. Proposes that the status of the United States' competitiveness may depend on how well we manage this process as much as on the resulting technologies themselves.…

Describes the Semiconductor Research Corporation (SRC), a non-profit research cooperative designed to conduct research in the field of integrated circuits, principally in U.S. universities, with membership restricted to U.S.-owned companies. Analyzes SRC's impact on the U.S. educational system. (TW)

Discusses the development of innovation and business incubators, including the stages of innovation typically addressed by such programs. Describes the efforts of the Thayer School, a graduate professional school at Dartmouth College, in establishing an innovation incubator. (TW)

Discusses some of the advantages and disadvantages of both live and videotaped presentations, particularly in regard to courses in mechanical engineering. Describes a graduate-level gas dynamics course that was offered live and on videotape to students both on and off campus by the University of Illinois (Urbana-Champaign). (TW)

Studies the quality of graduating science education majors at Brigham Young University (BYU) and attempts to identify possible trends in the ability of students who entered secondary school science teaching. Concludes that there was no manifested trend toward lower quality college students entering the science teaching profession at BYU. (CW)

Describes the evolution of the programs of the School of Natural Resources at Ohio State University. Discusses the historical events that led to the creation of the school, the development of various natural resources programs over the last 20 years, and the current development of new programs and degrees.
