An analogy between electron transfer reactions of the elements and those of organic molecules is offered. Examples of organic electron transfer reactions are presented. The rationale of constructing an organic chemists' periodic table is also discussed. (HM)

Described is a new approach to investigative physiology based on computerized transaxial tomography, in which visualization and measurement of the internal structure of the cardiopulmonary system is possible without postmortem, biopsy, or vivisection procedures. Examples are given for application of the Dynamic Spatial Reconstructor (DSR). (CS)

Explored were the effects on student attitudes of autotutorial laboratory instruction in a lower-division life sciences course designed for nonbiology majors at Skyline College, San Bruno, California. Positive results indicate the effectiveness of this mode of instruction in enhancing attitudes of students towards their learning and this…

Discusses some of the common problems facing the librarian of geoscience publications, including standards, criteria for selecting materials, budgets, and availability of materials. (SA)

Presents two examples of physics demonstrations: (1) vibrating aluminum rod suitable for use in a small room, and (2) vibrating white rubber tubing suitable for use with larger audiences. (SK)

Describes features and uses of the ZX81 microcomputer developed by Clive Sinclair. Includes a sample run and indicates that, although it is inexpensive, it can stand up against microcomputers costing several times as much. (SK)

Social, medical, and technological innovations are discussed, first with reference to historical examples and then with modern studies. The need for evaluating both the innovations themselves and the research processes leading to them is also discussed. Suggests needed research and explains new initiatives by AAAS in science and engineering…

Reviews the purposes of laboratory instruction as they were perceived in the literature from 1865 to the present. The paper is divided into three sections based upon the main influences on chemistry instruction: the university community, economic conditions, and technological development. Future trends in science education are also discussed. (CS)

Indicates that although Newton's achievements were rooted in an atomistic theory of matter resembling aspects of modern nuclear physics, Dalton developed his chemical atomism on the basis of the character of the gross behavior of substances rather than their particulate nature. (Author/SK)

Describes a circuit designed to measure time-of-flight velocity and shows how to use it to determine bullet velocity in connection with the ballistic pendulum demonstration of momentum conservation. (Author/GA)

It is suggested that short quizzes be given during the last ten minutes of lecture periods. Examples of the type of material that is recommended are presented. (BB)

Discusses how concept maps with two dimensional diagrams which show hierarchical relationships among concepts of a discipline can be used in teaching physics. An example for teaching a course in electromagnetism at the Federal University of Rio Grande do Sul, Brazil is presented. (HM)

Describes a systematic study of skills for solving problems in basic physics. Also discusses how detailed observations of individuals were used to formulate models for problem-solving processes in mechanics and applications for teaching basic college physics or engineering courses. (HM)

Presents results of the 1976 workshop organized by the European Communities' Biologists' Association (ECBA) in Amsterdam. Recommendations on university training of European biologists prior to specialization are included. (HM)

Describes the purpose of establishing the task force on teaching responsibilities, and outlines the recommended guidelines which called for clear definitions of conditions and components necessary for high quality physics programs. (GA)
