An understanding of classroom learning requires careful analyses of variables constituting the learning environment. Among those most likely influencing learning are verbal behaviors, since verbal interaction is the principal mode of communication in most classrooms. Thus, the quality of verbal interaction may directly affect the amount of…

This four-part booklet examines various issues related to nuclear weapons and how they will affect an individual working as a scientist or engineer. It provides information about the history of nuclear weapons, about the weapons industry which produces them, and about new weapons programs. Issues are raised so that new or future graduates may make…

Presented are abstracts and abstractors' analyses of nine studies related to curriculum and instruction. These studies focused on: (1) the status of environmental education in Kansas; (2) attitudes of Israeli students toward two versions of a curriculum titled Agriculture as Environmental Science; (3) interrelationships among teacher intentions,…

The connection between high school chemistry pedagogical experiences and introductory college chemistry performance has been a topic researched in published science education literature since the 1920s. However, analysis techniques have limited the generalizability of these results. This review discusses the findings of a large-scale,…

This report examines the impact of the Soviet Academy of Sciences on the development of technology in the Soviet Union, finding that the future of Soviet technology depends significantly on the Academy and that severe problems stemming from its nature and its relationship with Soviet industry encumber the Academy's ability to serve Soviet…

This collection of articles, originally published in national and international journals, is fifth in a series devoted to trends in teaching chemistry. The volume is divided into nine sections, each with an introduction explaining why papers have been selected and outlining their particular interest. Section I provides a list of atomic masses,…

Following a brief description of the major components found effective in school safety programs (safety management, education, and services) and data on school accidents in Iowa, this book addresses various aspects of safety related to science instruction, emphasizing that responsibility for safety must be shared by both teacher and students.…

This study guide is part of a program of studies entitled the Science and Engineering Technician (SET) Curriculum developed to provide a framework for training technicians in the use of electronic instruments and their applications. This interdisciplinary course of study integrates elements from the disciplines of chemistry, physics, mathematics,…

Reported are results of a study proposing to determine whether developmental patterns in correlational reasoning could be identified among a large and diverse sample; whether developmental patterns in correlational reasoning were similar regardless of problem context; and whether developmental patterns in correlational reasoning were similar for…

Five instructional techniques for increasing the meaningfulness of technical or scientific information are summarized: (1) organization of prose; (2) use of concrete analogy and advance organizers; (3) use of inserted questions in prose; (4) elaboration activities such as note taking; and (5) discovery learning. Research on each technique is…

This book, intended to serve as a resource guide for teachers wishing to implement computer-based learning in their own classrooms, is a collection of 29 classroom tested instructional programs designed to supplement an introductory chemistry course, regardless of text or approach. The programs cover a wide range of topics, from metric units of…

Piagetian levels of 126 volunteers (60 males and 66 females) were measured using the Burney Logical Reasoning Test. Findings demonstrated that the six predictor variables succeeded in explaining 58% (pooled male/female sample), 53% (female sample), and 59% (male sample) of the variance in Piagetian cognitive levels. In addition, since prediction…

THIS BULLETIN IS PRODUCED BY THE NATURE CENTERS DIVISION, NATIONAL AUDUBON SOCIETY TO PROVIDE PROFESSIONAL GUIDANCE AND TECHNICAL KNOW-HOW IN THE DEVELOPMENT OF COMMUNITY NATURE AND CONSERVATION CENTERS. THE TOPICS COVERED ARE--(1) PURPOSE AND VALUE OF A NATURE AND CONSERVATION CENTER, (2) INITIAL CONSIDERATIONS SUCH AS COMMUNITY READINESS, LAND…

ELEMENTARY, SECONDARY, AND COLLEGE LEVEL SCIENCE COURSE IMPROVEMENT PROJECTS ARE DESCRIBED. INDIVIDUAL PROJECTS ARE CLASSIFIED ACCORDING TO INSTITUTIONAL LEVEL AND ACADEMIC DISCIPLINE. MANY OF THE PROJECTS REPRESENT COMPLETE EDUCATIONAL PROGRAMS AND INCLUDE SUCH MATERIALS AS STUDENT TEXTBOOKS, LABORATORY MANUALS, SUPPLEMENTARY READINGS, TEACHER…

These materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. Soil heat flow and the resulting soil temperature distributions have ecological consequences…
