Describes experiences teaching biology for nonscience majors in Spring, 1967 by using taped-lecture and taped-documentary approaches. Indicates that, although pessimistic conclusions were arrived at, the documentary was superior to the taped blackboard lecture. (CC)

Describes an indirect laboratory method of calculating pi by using circular aluminum foil pieces as reactants with sodium hydorxide solution in a eudiometer, and indicates the presence of errors ranging from +0.05 percent of 3.1416 to +0.5 percent of 3.142. (CC)

Describes the conducting of three experimental courses by using texts, programmed supplements, lab manuals, behavioral objective sets, study guides, and tutoring and lecturing techniques in instruction. Indicates the feasibility of this model in institutions that can not use strict Keller Plan systems. (CC)

Introduces packaged learning modules in environmental and applied sciences education, general-education courses with emphases on chemistry impact on various institutions, methods of presenting homework solutions by tape cassettes, and experimental approaches to teaching of science for inservice elementary teachers in Vancouver, Canada. (CC)

Describes redesigning of a genetics course on the basis of Pella's referents, Banathy's system, and Bloom's taxonomy in effort to evaluate affectively behavioral changes among reference groups of science and nonscience majors, in addition to genetics students. Indicates preference of learning environment to course content in results analysis. (CC)

Presents an outline of the 1973 program and a summary of science education issues including curriculum developments at the graduate level. Discusses the controversy existing during hearings between the Foundation and the Committee on Science and Astronautics and between Congress and the Administration. (CC)

Describes a surgical technique for performing pinealectomics, applicable to classroom and laboratory studies, by using a head-holding device for small animals and a flat dissecting tray outfitted with holding straps for larger animals. (CC)

A discussion of Harvey's discovery of the circulation of blood illustrates that the contribution of the history of science can be logical as well as chronological. (DF)

Describes the use of audio-visual-tutorial methods in chemistry teaching which was reinforced by color slides, study guide, and laboratory experiments. Concludes the presence of satisfactory results when a minimum rate of progress was set out in advance. (CC)

Describes an interdisciplinary research project on production of food or fodder yeast from sewage. Indicates the presence of satisfactory educational and experimental results in operation of a pilot plant. (CC)
