The text of Volume 4 represents an international review of research in mental retardation dealing primarily with human and animal laboratory behavior. The contents range through the following topics: memory processes in retardates and normals by Norman Ellis; a theory of primary and secondary familial mental retardation by Arthur Jensen;…

The purpose of this study was to describe the implementation of a system of individually guided motivation utilizing individual and goal setting conferences. Before students were assigned to groups, they completed a self assessment form on which they rated themselves on 20 behaviors. Teachers from each Unit, using a Consensus method, also…

Provided are biological science laboratory experiments which have been developed and used as a part of an experimental one year undergraduate course in general science for non-science majors. The experiments are directed at the student understanding the balance of chemical and physical processes which must be maintained in order to sustain life,…

Provided are physical science laboratory experiments which have been developed and used as a part of an experimental one year undergraduate course in general science for non-science majors. The experiments cover a limited number of topics representative of the scientific enterprise. Some of the topics are pressure and buoyancy, heat, motion,…

This laboratory manual, part of a series of instruction books on basic experimental chemistry, is designed to provide the secondary school students of developing countries in Asia with laboratory experiences that bring out the fundamental concepts and ideas of chemical kinetics. Taking into consideration the possibility of limited facilities of…

The APPROACH (A Procedure for Patterning Responses of Adults and Children) technique was used to code observations of behavior and setting in this ecological study of adult-child cognitive communication patterns. The subjects observed were 32 children who proportionately represented each of four age groups (1 year, 2 years, 3 years, and 4 years)…

This paper asks whether all the current attention being given to educational evaluation and all the activity going on indicates real progress in the output of evaluation and its use in the policy process. The paper reviews the brief history of educational evaluation and gives a qualified "yes" as an answer to the question, noting: significant…

The primary purpose of this study was to determine if self-instructional data analysis sessions could be used effectively as traditional college laboratories to reinforce students' understanding of certain principles of mechanics. The secondary purpose was to determine whether any of the 140 college physics students involved had a dependence on…

Designed for use in Pennsylvania secondary school science classes, this guide is intended to provide fundamental information in each of the various disciplines of the earth sciences. Some of the material contained in the guide is intended as background material for teachers. Five units are presented: The Earth, The Oceans, The Space Environment,…

After an extensive study of the effective use of resources in colleges and universities the author offers some suggestions that envision radical rearrangements of higher education. Among his ideas are the following: (1) entrance requirements should be eliminated; (2) colleges and universities should be open to everyone the first year, and all…

Presented is a compilation of eight articles relating to science teaching in England, primarily at the secondary school level. An editorial describes recent changes in sciences and science education, decreased student enrollment in science courses, and increasing emphases on scientific methods training. The articles are then presented in three…

This publication is one of a series of single-topic problem modules designed for use in undergraduate geology and earth science courses. The first section, "Ain't It Flat? A Series of Experiments in Geodesy," presents various experiments for determining the earth's circumference (historically) and describes the use of satellites in determining the…

Experimental designs address themselves to two concerns: providing answers to research questions and controlling variance. The latter involves threats to internal and external validity. The threat to internal validity constitutes the greatest difficulty because of maturation, history, experimental mortality, and differential selection. Examples of…

This packet contains (1) informational booklets for parents in the Alum Rock Union Elementary School District, (2) a booklet on the pros and cons of a voucher system, (3) promotional material, (4) a progress report on the project, (5) the project proposal to OEO, and (6) a sample school and program preferences form. The program, according to the…

The objective of this manual is to provide a set of basic analytical procedures commonly used to determine environmental quality. Procedures are designed to be used in an introductory course in environmental science and are explicit enough to allow them to be performed by both the non-science or beginning science student. Stressing ecology and…
