An approach is suggested for teaching science history through inquiry training. A series of investigations are given for illustrating to students the manner in which organisms are grouped taxonomically. (SA)

Discusses various kinds of symbiosis including commensalism, protocooperation, mutualism. Examples are given of each, and emphasis is on the interdependence of living things. (SA)

Presents a discussion for the principles of a Fourier Transform infrared spectrophotometer which is intended to provide chemists with a basic understanding of these principles. (HM)

An elementary science teacher's technique for stimulating children to think visually, is presented. Through the medium of magic, children are given opportunities to form mental images to explain certain phenomena in science class. (SA)

Catalysis is defined and discussed as the process relates to science history, chemical reactions, enzymes, industry, catalytic reactors, and catalyst preparation. (SA)

Answers criticisms of "On What Basis Hope? Modern Progress and Postmodern Possibility" (Danforth), which used a postmodernist perspective to discuss the history and utilization of modern social science and the myth of scientific progress. The "validation trap" of scientific research and its limiting effect on innovation is discussed. (CR)

Describes the use of a computer-linked camera to demonstrate Coulomb's law. Suggests a way of reducing the difficulties in presenting Coulomb's law by teaching the inverse square law of gravity and the inverse square law of electricity in the same unit. (AIM)

Reports on Project 3 from the Evidence-based Practice in Science Education (EPSE) Research Network. This project explores issues surrounding the inability of many science teachers to enable students to understand the nature of science. (DDR)

Presents a Public Health Service (PHS) program as a model for implementing the Responsible Conduct of Research (RCR) instructional program. Describes an ethical decision making framework designed to guide a discussion of issues surrounding the responsible conduct of research and facilitates the consideration of ethical choices in the context of…

The benefits and disadvantages in conducting universal infant hearing screening and in the transition of audiology from a master's to a doctoral level profession are discussed from an epidemiological point of view. Epidemiologic strategies which may inform decision making in these two important and controversial areas are presented. (Author/CR)

Traces the development of an open-ended instrument, the Views of Nature of Science Questionnaire (VNOS), and outlines the nature of science framework that underlies the development of the VNOS. (Contains 63 references.) (DDR)

Investigates the relationship between knowledge of geometrical optics and the understanding of the phenomenon of colored shadows through adult interviews. Reports that the knowledge of geometrical optics facilitates the pinpointing of the color problem while experience with the mixing of paints may act as a barrier. (Author/YP)

Provides an inservice workshop experience for underprepared physics or physical science teachers. Describes a demonstration showing conservation of momentum using an air track, gliders, and a model railway train. Includes a brief introduction to demonstrations of Newton's second law, scattering of laser light, and the effect of a telescope on…

Describes three activities: "Solar Approach to Ohm's Law," dealing with the Ohm's law and the inverse square law; "Using LED's to Demonstrate Induced Current," showing Faraday's law and Lenz's law by using light emitting diodes (LEDs); and "The Helium-Filled Organ Pipe," discussing a discrepancy between theory and experiment. (YP)

Describes the theory and operation of a computer program which was written to balance chemical equations. Software consists of a compiled file of 46K for use under MS-DOS 2.0 or later on IBM PC or compatible computers. Additional specifications of courseware and availability information are included.
