Describes, and illustrates by reference to chemistry, a systems approach to the development of instructional segments. Uses a model with Behavioral, Temporal, and Substantive elements as axes. (AL)

Survey taken of Missouri chemistry teachers indicates that CBA and CHEM Study teachers devoted a greater portion of class time to laboratory work and emphasized quantitative laboratory work and the discovery method more than did teachers of conventional chemistry. (BR)

Reported is an evaluation of chemistry syllabuses in Scotland. The development of the curriculum reform movement is briefly sketched, syllabus content described, student reactions and attitudes noted, student performance surveyed, and experimental studies summarized. The author concludes that curriculum developers should be warned against…

Teaching science via a socio-historical approach utilizing selected concepts related to the social and historical development of science and selected concepts related to atomic energy was found to be feasible. (Author/CP)

Provides, from the author's experience as a curriculum development officer, some guidelines for planning instructional units. (AL)

Discusses ways to improve physics curricula, such as including events from science history and using discovery techniques. (MLH)

Describes an approach to chemistry for sixth form students which incorporates many practical applications of chemistry in the areas of pollution, drug problems and other areas. (BR)

Compared was the effectiveness of a two-year integrated chemistry-physics course with a two-year sequence of separate courses, in developing understanding of chemistry and physics concepts, understanding science and its methods, and reactions to the study of science. Both groups used the content, materials and instructional approach of the…

From an organizational point of view, a new high school physics program was developed. The teaching load was divided between two teachers. Benefits of the program were more preparation time for teachers and better student motivation. (PS)

A scheme is suggested for teaching concepts of polymer chemistry. Laboratory activities are suggested for the major topics. Interrelationships of different industrial uses of polymers are emphasized during the course. (PS)
