This module is designed to give the learner an understanding of the nature of light and how its properties are used in the design of spectrophotometers. Problems promote the use of spectrophotometers in qualitative analysis, the optical elements used in a monochromator, and the physical properties of the prism and the diffraction grating. Other…

This report addresses the initial phase of a multiphase effort to install Training Assistance Technology (TAT) capabilities on a submarine combat system trainer (SCST), and evaluate their effectiveness during a formal training course. This phase addresses the (1) selection of the trainer and course with which to conduct the evaluation, (2)…

A study was designed to (1) compare two types of reliability in the observation of teachers' behavior, (2) explore the relationship between observer reliability and the validity of their systematic classroom observations, and (3) investigate the effects of training, observer beliefs, and the passage of time on reliability and validity estimates.…

A program was initiated at Indiana State University (ISU), Terre Haute, to enable students to complete their student teaching during the summer. Twenty-four students participated in the program which provided four hours of activity daily, two to four hours of which were spent in teaching. Principles of using video tape for studying lesson…

This is the second in a series of guidebooks written for elementary school teachers to help improve their science teaching. The book emphasizes processes of science and creativity as well as science content. The book is divided into three sections--the atmosphere, the lithosphere, and the hydrosphere. Each chapter begins with simple concepts, and…

This is the third in a series of guidebooks written for elementary school teachers to assist them in improving their science instruction. The book attempts to emphasize processes and creativity as well as content. Atoms and molecules constitute the subject matter of the publication. Many experiments and demonstrations are included.

The University of California, Los Angeles (U.C.L.A.), Coordinators of Supervised Teaching in the elementary schools conducted a study to determine whether assignment to a poverty school (family income less than $4,000 per year) as opposed to assignment in an affluent school (family income in upper 10 percent, high-middle income neighborhoods)…

Helical scan video tape recorders were tested for their dubbing characteristics in order to make selection data available to media personnel. The equipment, two recorders of each type tested, was submitted by the manufacturers. The test was designed to produce quality evaluations for three generations of a single tape, thereby encompassing all…

The report provides an account of the work accomplished and the publications produced by the Council of Europe since 1967 concerning permanent education. Part 1 examines the historical perspective of permanent education, its development within the Council of Europe, and the implications of the principle of recurrence for other stages of the…

Investigates the effect of delay of reinforcement upon human discrimination learning with particular emphasis on the form of the gradient within the first few seconds of delay. In previous studies subjects are usually required to make an instrumental response to a stimulus, this is followed by the delay interval, and finally, the reinforcement…

The first article in this publication concerns radio-telemetry temperature studies of homoiotherms and poikilotherms. Radio telemetry reduces the problems related to demonstrating the differences between "warm-blooded" and "cold-blooded" animals; results may be plotted graphically, compared and used to generate classroom…

The problem of the uncooperative experiment arises with the use of human subjects. Evidence shows that typical volunteer subjects have the following characteristics: better education, higher paying jobs, greater need for approval, lower authoritarianism, higher I.Q. score, and better adjustment to personal questions than nonvolunteers. Data also…

The purpose of this study is to determine categories of learning styles based on research on the chemical and physiological correlates of learning, as well as the development of simple measures that would allow an investigator to place a subject within one or more of these categories. The data from eight experiments with rats suggests that there…

The purpose of this study was to determine: (1) the effects of repeating words in compound sentences; and (2) the differences in encoding processes in short term memory for natural language materials compared with nonlinguistic material. A series of give experiments was administered to first graders, college students, and older subjects. The…

Two separate subject matter areas were selected for investigation which were felt to represent two distinct types of learning situations. One was a kind of logico-mathematical procedure; the other was a visual form discrimination task. Two separate courses were developed for each subject matter area. One reflected an inductive instructional…
