The paper has three major objectives. The first objective of the paper is to synthesize and define common categories of meta-analysis. The second objective is to propose a way to comprehend these common categories of meta-analysis through learning from their respective generic conceptual frameworks. The third objective is to point out which R…

This powerful resource is for researchers and educational leaders who are interested in understanding and applying research methods that emphasize youth voice. The authors argue that most educational research either omits critical understandings of youth or, even worse, presents inaccuracies due to faulty techniques. Researching how youth…

The purpose of this article is to clarify the discrepancy in the use of "queer" as a sexual identity classification in education survey research. This study extends the work completed by Dugan and Yurman (2011), who empirically demonstrated problems with treating LGB students as a homogenous population through collapsing all respondents…

A reliable and practical subtype system of stuttering should enhance all related scientific work concerned with this disorder. Although a fair number of classification systems have been offered, to date, none has received wide recognition or has been routinely applied in research or clinical spheres. Whereas progress has been made in understanding…

A total of 61 children from first through sixth grades participated in four balance-scale and four inclined-plane problem types in a study testing for invariance of subject classifications as rule-users across problems whose products differed but whose type did not. Results indicated that many children's classifications differed across…

Adopting the position, expressed by A. P. Bochner in his critique of small group communication research, that placing measurement in a secondary role increases the danger of accepting the claims of experiments with excessive error, this paper examines nine current quantitative small-group communication studies. Using a schema developed by J. F.…

This discussion of issues of definition and classification of attention deficit disorder (ADD) emphasizes the heterogeneity of the diagnosis, the overlap of ADD with reading disability, and lack of consistency across studies. A systematic classification study is proposed to develop a unitary, empirically derived classification for ADD. (Author/DB)

The hypothesis is the device scientists use to translate questions, theories, or proposed explanations into a form amenable to empirical research. This edition of W. W. Charter's treatise on clear, conceptual definitions and precise operational hypotheses, which was originally developed to assist students in educational policy and management…

This reaction paper criticizes the characterizations of clusters used in a study concerning a taxonomy of lifestyles of families with severely mentally retarded children, by I. T. Mink and others (EC 211 387). The criticism focuses on the use of cluster scores on criterion variables and use of cluster profiles across studies. (JDD)

This commentary responds to a critique (EC 601 711) of a paper (EC 211 387) concerning use of cluster analysis to develop a taxonomy of lifestyles of families with severely mentally retarded children. The commentary considers the model to be useful in social science inquiry, and properly validated when using cluster analytic techniques. (JDD)

Discusses problems of classifying racial and ethnic groups when collecting statistical data. Argues that surveys must acknowledge the great diversity of the American population and give respondents the freedom to choose the group or groups to which they belong. (FMW)

This survey of nine journals identified two distinct cultures in mental retardation research: classification by level of retardation (usually by psychologists and special educators) or etiology (usually by geneticists and psychiatric researchers). The paper discusses varied effects that genetic etiology may have on behavior, issues in reconciling…

To control for interactions in learning research due to subjects' prior knowledge of the instructional material presented, an imaginary curriculum was presented with a computer assisted technique based on Carl Berieter's imaginary science of Xenograde systems. The curriculum consisted of a classification system for ten conceptual classes of…

Argues that rank order correlations may not be ubiquitously suitable for assessing the relations between children's behavior or characteristics at one age or in one situation, and those shown later or in another context. (HOD)
