Discussed is the historic development of Snell's law and derivation of the law without using mathematical expressions. Describes laboratory procedures using diagrams. (YP)

Summarizes research on inquiry and investigative strategies for teaching laboratory science. Concludes that meaningful laboratory instruction is distinguished by: student engagement in science inquiry processes, student manipulation of experimental materials, and the experiential teaching of specific scientific concepts. (RT)

Describes exercises in which tabs from aluminum beverage cans are used to introduce principles of classification, biostratigraphy, and evolution. Provides diagrams which represent dorsal and ventral views of species and a table which graphs units of time in relation to species duration. (RT)

Describes the contribution made to the quality of human life by the study of genetics. Presents a description of the current status of genetics education. Suggests changes in genetics education necessary to keep up with new developments. (39 references) (CW)

Glaring and basic textbook errors and misconceptions about photosynthesis are discussed. The Calvin Cycle, photosynthetic products, alternative cycles, and plants as producers are considered. Included are observations of both college and secondary textbooks. (CW)

Described is a laboratory study designed to demonstrate loss of vegetation, alterations in the species composition of a community, and the impoverishment of a community with respect to desirable food plant species when herbivore feeding exceeds the rate of vegetation regrowth. The laboratory uses a classroom aquarium. (CW)

Described is a study conducted to measure trends in the coverage of environmental issues by popular magazines during 1961-86. Suggested that coverage increased during this period and that environmental articles have become more mainstream. (CW)

Reviewed are three controversial incidents from the history of biomedical science for the lessons they may teach about the nature and context of scientific discoveries. Considered are William Harvey and blood circulation, Louis Pasteur and spontaneous generation, and Frederick Banting's discovery of insulin. (Author/CW)

Discusses student difficulties in problem solving. Presents a structured approach to one-dimensional constant acceleration problems. Provides researcher's experience including an example problem, advantages of the approach, and student responses with two illustrations of problem solving. (YP)

Describes a demonstration of the transmission of data signals from one microcomputer to another using an optical fiber line. Discusses the set-up method and demonstration steps for sending program and graphics. Provides a block diagram of the system and two circuit diagrams. (YP)

Described is an experiment for measuring the coefficient of restitution with a meter stick, balls of different types, and scraps of material for the plates. Provides the experimental procedure and an apparatus diagram. (YP)

States that the downward movement in undergraduate engineering enrollments can be attributed to demographic factors. Provides data on enrollment in specific schools and states, including details for women, minorities, and foreign nationals (in engineering only). Cites information for each program title within the general disciplinary groups. (RT)

Discusses procedures used to evaluate and enhance the journal's effectiveness. Presents survey methods and information on membership perception, results, a background discussion, and recommendations for changes. Tables on production and subscription data, survey attitudes of department heads and reviewers, and topics for review articles are…

Discusses procedures for teaching basic soil morphological concepts using soil cores collected along a toposequence. Describes materials and methods for collecting, laboratory use of cores, and student evaluation results. Shows a table of criteria used to describe soils for profile descriptions. (RT)

Investigates using the microcomputer to develop a sentence parser to simulate intelligent conversation used in artificial intelligence applications. Compares the ability of LOGO and BASIC for this use. Lists and critiques several LOGO and BASIC parser programs. (MVL)
