This commentary explicates two principal arguments against the conclusions drawn by Robin Perry in his article "Do Social Workers Make Better Child Welfare Workers Than Non-Social Workers?" The first concerns the methodology used, whereas the second centers on the measurement of the dependent variable, performance expectation. Considering the…

Analysis of variance (ANOVA) was invented in the 1920s to partition variance of a single dependent variable into uncorrelated parts. Having uncorrelated parts makes the computations involved in ANOVA incredibly easier. This was important before computers were invented, when calculations were all done by hand, and also were done repeatedly to check…

Analysis of variance (ANOVA) is a frequently used statistical procedure in education and the social sciences. Very often the use of ANOVA involves situations with unequal cell sizes. When confronted with data to analyze from an unbalanced design, the researcher should select very carefully from the method or option in the statistical package being…

Errors in methodology occur regularly in the conduct of surveys for educational research. This paper discusses some of these errors and alternatives. In the area of survey design, errors are common in: (1) missed opportunities in attitude scale planning; (2) blunders in item construction; (3) missed opportunities in item construction; (4) blunders…

A brief discussion of children's perceptions of animate and inanimate objects. It is suggested that studies on child animism must consider the child's criteria used in the classification of animate objects, as well as those used for inanimate objects. (Author/ED)

An announcement of a project to be commenced at the University of Newcastle upon Tyne in October 1968, given at the International Seminar on Experimental Research in Music Education (Reading, England, July 9-16, 1968).

Investigated is the topic of research implementation and how it can affect evaluation results. Even when evaluations are well planned, the obtained results can be misleading if the conscientiously-constructed research plan is not correctly implemented in practice. In virtually every research arena, one finds major difficulties in implementing the…

This conference was designed to facilitate an exchange of information and experiences on the major issues in research with human subjects. In each session, a speaker from the United States and one from the United Kingdom reviewed procedures, progress, and problems related to a particular topic, leading to a thorough discussion of the advantages or…

THIS MONOGRAPH WAS WRITTEN FOR EDUCATORS INTERESTED IN INITIATING RESEARCH STUDIES ON UNDERACHIEVEMENT AND OVERACHIEVEMENT. DEFECTIVE EXPERIMENTAL PLANNING, INHERENT DEFICIENCIES IN CONCEPT DEFINITION, AND OTHER FACTORS RESULTING IN FACULTY RESEARCH DESIGN RENDER MANY RESEARCH FINDINGS IN THIS AREA INCONCLUSIVE OR MISLEADING. THE CONCEPTS OF…

THE PURPOSE OF THIS MONOGRAPH IS TO DISCUSS SOME PRINCIPLES OR GUIDES THAT SHOULD BE KEPT IN MIND TO INSURE DEVELOPMENT OF SOUND RESEARCH CONCLUSIONS AND RECOMMENDATIONS BY WHICH THE QUALITY OF BUSINESS EDUCATION CAN BE UPGRADED. THE MAJOR DIVISIONS ARE (1) NATURE OF SCIENCE AND ITS RELATIONSHIP TO PHILOSOPHY AND ART, (2) NATURE OF SCIENTIFIC OR…

This is an experimental 2-phase study which focuses upon perceived respondent burden (PRB), that is, upon negative feelings which may be experienced by people who participate in household surveys. For phase 1 of the study, whose results are reported here, the effects of two variables-- interview length and interview effort--upon PRB were assessed.…

The repeated measures design is of importance to those interested in doing learning studies concerned with repeated trials on a single type of task, repeated trials on different tasks, or both together crossed with and following different treatments. In doing analysis of variance with such data it is assumed that the data fits an additive model.…

This book presents controversial aspects of evaluation and aims at broadening perspectives and insights in the evaluation field. Chapter 1 criticizes modes of evaluation and the basic rationality behind them and focuses on assumptions that have problematic consequences. Chapter 2 introduces concepts of evaluation and examines methods of grading…
