Reexamines existing research in persuasion by testing the predispositional and alignmental hypotheses. Evidence of past investigative failures is discussed and implications for future research are presented. (MH)

Describes programs that have been developed to allow kinetic experiments to be simulated on a small computer. Reports the principles that have guided the conception of the programs and describes an instance of their application to a complex reaction. (Author/GS)

Information related to the history of optics with emphasis on the classical and medieval periods is presented. Notes are included on experiments dealing with refraction at a plane interface between two media; refraction by transparent spheres; light, color, and reflection by transparent spheres. (Author/SA)

The life and work of Isaac Newton and his investigations of light and color are described in detail. Notes include preliminary observations of chromatic dispersion; dispersion by an equilateral prism; the "Experimentum Crucos" or the composite nature of white light; the nature of colored light and illumination; transmissions and…

Presented is information related to the life and work of Charles Coulomb as well as detailed notes of his measurements of the distribution of electricity on conductors. The two methods that he used (the large torsion balance, and the timing of "force" oscillations) are described. (SA)

This publication is a systematized annotated bibliography of environmental education materials. The materials listed are grouped according to instructional methodology or format so that publications which may be used in similar ways are grouped together. Each publication is listed under every appropriate instructional category. Instructional…

This book contains 65 physics experiments. The experiments are for a college-level physics course for music and art majors. The initial experiments are devoted to the general concept of vibration and cover vibrating strings, air columns, reflection, and interference. Later experiments explore light, color perception, cameras, mirrors and symmetry,…

Presented is a review of three methods for evaluating the effects of laboratory work in high school science instruction. The report focuses specifically on evaluating student performance, what aspects are to be evaluated, and how to evaluate. A table is given of some of the limitations and benefits of each of the assessment procedures. The authors…

BASIC OBJECTIVES OF THIS EXPERIMENT WERE TO USE TEAM TEACHING BY TV TO HELP STUDENTS GAIN A REALISTIC VIEW OF THE INDUSTRIAL PROCESS AND OF THE IMPORTANCE OF EDUCATION AND TRAINING FOR PARTICIPATION IN THAT PROCESS. GRADE EIGHT STUDENTS IN AN INDUSTRIAL COMMUNITY WERE PLACED IN AN EXPERIMENTAL AND A CONTROL GROUP, AND EXPOSED TO INSTRUCTION FROM…

THIS REPORT IS A BRIEF REVIEW OF RESULTS OF AN EXPERIMENT TO DETERMINE THE INFORMATION RETRIEVAL EFFICIENCY OF A MANUAL SPECIALIZED INFORMATION SYSTEM BASED ON 700,000 DOCUMENTS IN THE FIELDS OF ENDOCRINOLOGY, STRESS, MAST CELLS, AND ANAPHYLACTOID REACTIONS. THE SYSTEM RECEIVES 30,000 PUBLICATIONS ANNUALLY. DETAILED INFORMATION IS REPRESENTED BY…

THIS VOLUME IS A COLLECTION OF EIGHT PAPERS DEALING WITH ASPECTS OF TEACHING PHYSICS TO RUSSIAN STUDENTS IN GRADES FIVE THROUGH ELEVEN. TOPICS OF PAPERS ARE (1) THE PRESENT SITUATION IN THE METHOD OF HIGH-SCHOOL PHYSICS AND ITS BEARING ON THE POLYTECHNICAL INSTRUCTION SYSTEM, (2) THE DEVELOPMENT OF RATIONAL THOUGHT IN STUDENTS DURING THE TEACHING…

INCLUDED IN THIS MANUAL WRITTEN FOR SECONDARY SCHOOL AND COLLEGE TEACHERS ARE DESCRIPTIONS OF DEMONSTRATION MODELS, EXPERIMENTS PERTAINING TO SOME OF THE FUNDAMENTAL AND APPLIED METEOROLOGICAL CONCEPTS, AND INSTRUCTIONS FOR MAKING SIMPLE WEATHER OBSERVATIONS. THE CRITERIA FOR SELECTION OF TOPICS WERE EASE AND COST OF CONSTRUCTING APPARATUS AS WELL…

GREATER UNDERSTANDING OF INFERENTIAL STATISTICAL METHODS AND EXPERIMENTAL DESIGN WOULD ENABLE LANGUAGE TEACHERS TO INTERPRET OBJECTIVELY AVAILABLE RESEARCH REPORTS AND HOPEFULLY WOULD ENCOURAGE MORE EXPERIMENTATION. TO UNDERSTAND THE EXPERIMENTAL PROCESS, EDUCATORS MUST REALIZE THAT ANY EXPERIMENT IS AS SUCCESSFUL AS THE EXPERIMENTER IS IN…
