A series of educational experiments are being conducted in Canada on the Communications Technology Satellite. The description of these experiments reveals a diversity not previously encountered in educational applications of satellite systems. In evaluating these experiments, the authors adopted Stufflebeam's Context-Input-Process-Product model in…

Measurements of various parameters derived from different reaction time (RT) paradigms are found to be correlated with psychometric measurements of general mental ability. Such RT-derived measurements, when combined in a multiple regression equation, predict some 50 percent or more of the variance in intelligence. This relationship of intelligence…

This is the final report of the evaluation of Project CAUSE, a three year project to improve the laboratory portions of undergraduate physics courses at North Texas State University. The report is divided into six sections. Included in the overview are goals and purposes, the instructional format, and the evaluation plan. Demographic profiles…

Longitudinal and intervention laboratory studies were conducted to investigate the effects of viewing televised violence on the aggressive behavior of elementary school children. In the longitudinal study 505 children were studied over a 3-year period. The measures used included peer nominated aggression, aggression anxiety and popularity,…

A SPEECH THERAPY METHOD FOR MENTAL RETARDATES WAS DEVELOPED AND EVALUATED. THE METHOD WAS BASED UPON THE ESTABLISHMENT OF FAVORABLE ASSOCIATIONS IN THE CHILD BETWEEN THE WORDS AND SOUNDS OF LANGUAGE AND THE PRODUCER OF THE LANGUAGE, USING STIMULUS-REWARD AND SITUATION-REWARD PRINCIPLES. TRADITIONAL METHODS OF SPEECH THERAPY WERE ADMINISTERED,…

NINTH GRADE STUDENTS ENROLLED IN FIRST-YEAR VOCATIONAL AGRICULTURE IN TWENTY-SEVEN NEW YORK SCHOOLS MADE UP THE SAMPLE. TEACHERS WERE CONTACTED BY MAIL, SUPPLIED WITH THE MATERIALS AND INSTRUCTIONS, AND DID THE ACTUAL ADMINISTERING OF THE TREATMENTS. INTACT CLASSES WERE RANDOMLY ASSIGNED TO ONE OF THREE CONDITIONS. GROUP 1 RECEIVED PROGRAMED…

This guide is designed to assist teachers in involving students in individual or small group laboratory investigative experiences in the life sciences. Each of the 22 experiments contains a prelab and postlab section for teachers and a detailed procedures section for students. (Author/CO)

This paper represents two intentions: to discuss the need for theoretical advance in generational studies, and to make suggestions about expanding the design repertoire of generational studies in the interests of these theory developments. First, because generational phenomena on the face seem intransigent to experiment, a comment on…

This workbook contains laboratory exercises designed for use in a college introductory biology course. Each exercise helps the student develop a basic science skill. The exercises are arranged in a hierarchical sequence suggesting the scientific method. Each skill facilitates the development of succeeding ones. Activities include Use of the…

The Radio Mathematics Project was established to design, implement, and evaluate a prototype system of teaching elementary mathematics using radio as the major medium of instruction. The project, working in rural and urban primary schools in Nicaragua, presents daily mathematics lessons in second and third grade classrooms. Each lesson has a 30…

This paper discusses ways managers can motivate their employees to work and at the same time to increase their performance. Two theories of motivation--Vroom's theory and Atkinson's theory--focus on the use of extrinsic and intrinsic rewards respectively. A managerial strategy that combines the best of both intrinsic and extrinsic approaches to…

This document is a report on a course in nuclear science for the high school curriculum. The course is designed to provide a basic but comprehensive understanding of the atom in the light of modern knowledge, and to show how people attempt to harness the tremendous energy liberated through fission and fusion reactions. The course crosses what are…

This guide contains lesson plans and outlines of science activities which present concepts of solar energy in the context of biology experiments. Each unit presents an introduction; objectives; skills and knowledge needed; materials; methods; questions; recommendations for further work; and a teacher information sheet. The teacher information…

The scientific method is described as intending to be the guarantor of objectivity, neutrality, and diligent application of its rigorous procedures and to produce a body of cumulative knowledge that is systematic and general. The central argument of this essay addresses the discovery that research findings appear to be context-dependent; methods…

THE PROGRESS OF THE RESEARCH AND DEVELOPMENT (R AND D) PROGRAM IN VOCATIONAL-TECHNICAL EDUCATION DURING THE FIRST 18-MONTH CONTRACT PERIOD IS SUMMARIZED, AND PROJECTIONS ARE MADE REGARDING ITS FUTURE OPERATION. THE R AND D PROGRAM IS ROOTED IN THE CLINICAL APPROACH TO TEACHER EDUCATION AND PROGRAM EXPERIMENTATION. THIS APPROACH UTILIZES THE…
