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…

The issue of the "research-practice gap"--the problematic relationship between research in education and educational practice--has been widely reported in the literature. This critical literature review explores some of the causes and features of the gap and suggests some possible approaches for addressing it. These solutions involve changes in…

Meta-analysis does not solve all the problems encountered in qualitative research reviews, but it holds out some hope for increasing the reliability and dependability of a reviewer's conclusions. Several developments in meta-analysis are cause for optimism. First, different meta-analysts are doing work in the same areas, leading to increased…

The most important problem in psychology and the social sciences today is the failure to produce cumulative knowledge. This situation has led many to conclude that cumulative knowledge and general principles and theories may be impossible to establish in psychology, a conclusion suggesting that psychology can never be a science--only at best a…

Identifies three sources of reporting deficiency for meta-analytic results: quality (adequacy) of publicizing; quality of macrolevel reporting, and quality of microlevel reporting. Reanalysis of 25 reports from the Smith, Glass and Miller (1980) psychotherapy meta-analysis established two sources of misinformation, interrater reliabilities and…

The paper discusses problems resulting from the substitution of meta-analysis for qualitative reviewing of special education research, employing H. Cooper's framework for assessing integrative research review and using illustrations from research on class placement and mainstreaming. (Author/CL)

A quantitative method, meta-analysis, is used to integrate research findings from a representative group of 38 coaching studies. Because different studies reported results on different scales, effect size was used to transform all results to a common metric. This meta-analysis showed that there are two distinct literatures on the effectiveness of…

Examines 2,000 Strange Situation classifications obtained in eight different countries. Differences and similarities between distributions in classifications of samples are investigated using correspondence analysis. Substantial intracultural differences are established; data also suggest a pattern of cross-cultural differences. (Author/RWB)

Monte Carlo studies explored the sampling characteristics of Cohen's d and three approximations to Cohen's d when used as average effect size measures in meta-analysis. Reviews of 10, 100, and 500 studies (M) were simulated, with degrees of freedom (df) varied in seven steps from 8 to 58. In a two independent groups design, samples were obtained…

There exists an abundance of research on topics relevant to the decisions organizations must take in allocating and developing their resources. This paper addresses the problem of integrating those research results. Data needed for the meta-analysis approach to research integration are sometimes not available in the published literature.…

A meta-analysis was conducted on 44 educational studies that used either a (labelled) Hawthorne control group, a manipulation of Hawthorne effects, or a group designed to control for the Hawthorne effect. The sample included published journal articles, ERIC documents or unpublished papers, and dissertations. The studies were coded on 20 variables,…

Reported in this paper are the findings of five meta-analyses assessing the relationships among children's interpersonal cognitive problem-solving (ICPS) skills, training, and behavioral adjustment. Five hypotheses were examined: (1) Adjusted children score higher on ICPS measures than do nonadjusted children; (2) Children trained in ICPS skills…

The purpose of this study was to determine the types of research methods used to study cognitive processing development in gifted learners, from 1975-1986. Of 870 research publications identified on giftedness, 522 publications (60 percent) dealt with cognitive processing development. Research designs used most frequently were causal-comparative,…

The status of recent research on staff development and inservice education for teachers, administrators, and other school personnel was reviewed in studies completed between 1977 and 1984. More than 400 articles from 23 professional journals and 507 doctoral dissertations were analyzed. For each study, the research design and procedures, purposes…

Reviews, analyzes, and critically assesses a sample of articles reporting research findings related to the instructional effectiveness of computer-assisted instruction (CAI). Problems in CAI research are described, including validity of the experimental research design, and current trends in CAI research are discussed. (31 references) (LRW)
