There is evidence that violence in motion pictures viewed by children on screen or television can contribute to violence in real life, although the movies can rarely be blamed as the sole cause of anti-social conduct. Clinical reports cite instances of the effect on "susceptible" youngsters; e.g., emotionally disturbed individuals. Long-term…

An experiment was designed to test the hypothesis that a program of prompting, practice, and feedback would improve the beginning teacher's ability to observe pupil performance in the classroom. Eighty-four teacher education students were randomly assigned to four 35-minute treatments: (I) viewing an instructional video tape of 21 brief…

The experiment studied the "relative effectiveness of tangible and social rewards upon the performance of a simple discrimination learning task by culturally disadvantaged children." Also assessed were the effects of the sex of the subjects (Ss) and the examiner. Ss were 144 five- and six-year old youngsters in a Georgia Head Start…

A laboratory study was performed with four levels of discovery and two levels on an overlearning factor. An improved experimental paradigm was chosen so as to avoid a number of confusions which have obscured previous research. An operational definition was developed for discovery and guided discovery and discovery teaching, and inquiry learning.…

This book was developed for use in India and is adapted from "Ideas for Science Investigations" by Victor M. Showalter and Irwin L. Slesnick. It is a source book of ideas for student research projects. Three model projects are described, illustrating different approaches taken by three students to the investigation of the rise of sap in…

In 1973 the Michigan Department of Education and the Cooperative Accountability Project attempted to develop a greater understanding of the problems which might be associated with dissemination of information about educational accountability programs. From this project three papers resulted that outlined a potential dissemination model designed to…

The effects of stress on state anxiety and heart rate of male high school subjects were investigated. Two psychomotor tasks were used. In the stress condition, subjects received negative feedback about performance; the subjects in the nonstress condition were given rest intervals. Subjects in both conditions showed differing regression lines. The…

The unit presented in this teacher's guide is the first of two developed for the fifth year in the Science Curriculum Improvement Study (SCIS) curriculum. Attention is focused on energy transfers involved in the interaction of matter in solid, liquid, and gaseous forms. The chapters are presented in six parts which include activities for reviewing…

The author views the primary purpose of the modern engineering laboratory as teaching the student how to experiment. An attempt is made to update the engineering laboratory and make it generally meaningful for all students, whether headed for graduate school or an industrial job. The intent is to broaden the experimental picture so that students…

The publication presents outlines of some of the difficult experiments suggested in the chemistry syllabus for the Certificate of Sixth Year Studies in Scotland. The experiments included in the publication form a small part of the total experiments suggested in the syllabus. Simple experiments, the details of which are available in textbooks, are…

This report attempts to cut through the rhetoric of both the opponents and the proponents of performance contracting and to bring the main issues into focus. The report (1) describes different kinds of contracts; (2) discusses testing problems; (3) gives a description of the Texarkana and Banneker elementary school projects; (4) provides sample…

Much of the current research in experimental plant biology requires highly uniform plants. To achieve this, many plants are grown under conditions in which the environment is carefully manipulated. This pamphlet has been prepared, therefore, to present and describe growth procedures which will produce vigorous, healthy, uniform plant material in…

This paper emphasizes the need for empirical research and objective discovery procedures in semantics, and illustrates a method by which these goals may be obtained. The aim of the methodology described is to provide a description of the internal structure of a semantic field by eliciting the description--in an objective, standardized manner--from…

This manual is designed for use in the laboratory phase of courses dealing with microbial aspects of pollution. It attempts to cover the subject area broadly in four major categories: (1) microorganisms in clean and polluted waters, (2) carbonaceous pollutants, (3) nitrogen, phosphorus, iron, and sulfur as pollutants, and (4) sanitary…

The investigations for topics 9-14 in the earth science course developed by The University of the State of New York for secondary schools are contained in this supplement to the syllabus (ED 046 749). The topics in this supplement include the erosional process, the depositional process, the formation of rocks, the dynamic crust, interpreting…
