Seven domains upon which public policy is said to have an impact are differentiated here. A major intention of the paper is to distinguish between science and trans-science and the validity of including non-objective phenomena as an input into public policy evaluation and formation. (Author/AM)

Presents an analysis of the conceptual demands of Nuffield O-level biology, outlines the teaching strategy of the course, describes the population for whom the course is suited, and relates possible instructional modifications for those pupils not ideally suited for the course. (GS)

The science curriculum in Anne Arundel County Maryland specifies a scheme for major unifying concepts in science and a scheme for scientific literacy as the basic structure of the program. (GS)

Describes a course developed in the United Kingdom that uses a patterns approach to science teaching. Outlines eleven novel features of the course and describes a method of integration that offers complete instructional flexibility. (GS)

Presents information about an atomic model of haemoglobin and describes the oxygenation mechanism as a teaching principle to illustrate the relationship between structure and function at the molecular level. (Author/PEB)

Traditionally, the Doppler effect for sound is introduced in high school and college physics courses. Students calculate the perceived frequency for several scenarios relating a stationary or moving observer and a stationary or moving sound source. These calculations assume a constant velocity of the observer and/or source. Although seldom…

A low-cost tensile testing machine was built for testing polymeric films. This apparatus also allows for tear-strength and flexural tests. The experimental results, obtained from common-use materials, selected by the students, such as plastic bags, illustrate important aspects of the mechanical behavior of polymeric materials. Some of the tests…

This book is written for children ages 5 through 10. Part of a series designed to develop their curiosity, fascinate them and educate them, this volume provides information on the origin and uses of salt, both in the ancient world and today. Topics are: (1) relationship of salt to the human body; (2) collection methods; (3) uses for human life;…

This is one in a series of publications designed for parents and teachers to help children acquire developmentally appropriate basic educational skills at home and in school. Topics included are: (1) "What is science?"; (2) "Why is science important?"; (3) "How children develop science skills?"; (4) "You can help…

This study evaluated the effectiveness of the use of videodisc technology in a school system. The videodisc "Understanding Chemistry and Energy" (Systems Impact, 1987) having 20 lessons was used in Physical Science classes (grade 9) and Biology classes (grades 10 and 11) in an experimental school. It was designed to be used with a variety of…

A brief overview of the history of the scientific study of the child in Canada is provided in this paper. Discussion begins with an account of the scholarly interests and activities of James Mark Baldwin, who brought modern psychology to Canada, and Frederic Tracy, who objected to child-centered approaches to child rearing. The remainder of the…

Students (N=22) enrolled in secondary school biology were evaluated for their abilities to use: combinatorial logic; correlational reasoning; separation and control of variables; exclusion of irrelevant variables; proportional reasoning; and probabilistic reasoning. Each student responded individually to six Piagetian tasks designed to measure…

Described is the use of praying mantises as organisms to illustrate the concept of predator. (PEB)

Inquiry has been one of the most prominent reforms in science education. One of the goals of teaching through inquiry methods is to enable students to have experiences that are authentic to scientists' experiences. Too often, inquiry science is taught as either the "scientific method" or as "hands-on," disconnected activities…
