Presented is a review and synthesis of research in science education conducted with students in grades 6 through 12 during the years 1964-78. In the meta-analysis process, eight constructs linked to learning outcomes were used as the theoretical constructs for the literature selection. The constructs include quality and quantity of instruction;…

Presented are the results of an exploratory study in which methods used in research on teaching were adapted to research on elementary school science teaching. An observation system was designed that enabled an observer to record detailed, context-specific information about the behavior of teachers (N=22) and students in grades 2-5 during…

Appropriate technology is an approach to meeting human needs which stresses local solutions using small-scale decentralized technologies that have minimal environmental impact. Presented in this manual are 10 lessons for upper elementary students that consider such topics as recycling, solar energy, transportation, and nutrition. Each lesson…

This learning module is concerned with the temperature field, the heat transfer rates, and the coolant pressure drop in typical high temperature gas-cooled reactor (HTGR) fuel assemblies. As in all of the modules of this series, emphasis is placed on developing the theory and demonstrating its use with a simplified model. The heart of the module…

This module is part of a series on Physical Processes in Terrestrial and Aquatic Ecosystems. The 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.…

Difficulties in implementing the EXCHECK/Voice Oriented Curriculum Author Language (VOCAL) System, a general program designed for university-level computer-assisted instruction in mathematics and science written in the VOCAL language, are presented in terms of informal mathematical procedures, audio and prosodic features, and a schedule of…

This final report on field testing of minicourses in undergraduate biology lists the objectives, procedures, applications, and conclusions of the project in which twelve schools utilizing minicourses, developed at Purdue University, were sampled. Data were collected and analyzed on student achievement, student attitude changes, and student…

Presented are environmental education lessons adapted for use in the second-grade classes of Pinellas County, Florida. Many examples are drawn from local situations. Six conceptual schemes provide the guide's organizational framework: interrelationships, heredity and environment, change, effects of population growth, finite resources, and…

This article presents a rationale for incorporating reading activities with science. It emphasizes that science investigations can provide a background for, and an interest in, reading among students. Three approaches for using science as a vehicle for reading are given: (1) the unit approach; (2) the tradebook, activity card approach; and (3) the…

This publication is a laboratory study guide designed for mechanical engineering students. All of the experiments (with the exception of experiment No. 1) contained in the Mechanical Engineering Laboratory Manual have been included in this guide. Brief theoretical backgrounds, examples and their solutions, charts, graphs, illustrations, and…

This paper is divided into two sections. The first section presents a discussion of the characteristics of the disadvantaged child and the ways in which the philosophy and approach of the Science Curriculum Improvement Study (SCIS) meets his/her needs. The second half is devoted to the descriptive reports from teachers and administrators in whose…

This report presents the results of an investigation of the Science Curriculum Improvement Study (SCIS) program and the effects of the Materials Objects unit on first-grade students and teachers. The contents of the report include purposes and limitations of the study, discussion of the instruments, observers, reliability of the Q sort, the…

THIS IS AN OUTLINE OF PROCEDURES FOLLOWED IN DEVELOPING EXHIBITS SUITABLE AS AUTOINSTRUCTIONAL DEVICES AND AS DEMONSTRATION DEVICES FOR EDUCATIONAL TELEVISION PROGRAMS. THE 27 TEACHING EXHIBITS WERE DESIGNED TO HELP STUDENTS UNDERSTAND CONCEPTS AND PERFORM EXPERIMENTS IN PHYSICS, MATHEMATICS, CHEMISTRY, AND BIOLOGY. SOME OF THE EXHIBITS EMPLOYED…

The Secondary and University Education Section of the National Heart and Blood Vessel Research and Demonstration Center (NRDC) at Baylor College of Medicine completed a statewide survey of Texas public secondary school teachers of biology, health education, homemaking, and physical education. The survey ascertained: (1) the status of…

Students in general undergraduate courses in both biology and genetics seem to have great difficulty mastering the basic concepts of Mendelian Genetics and solving even simple problems. In an attempt to correct this situation, students in both courses at Rollins College were introduced to three simulation models of the genetics of the fruit…
