As performance-based assessments have gained wider use, there are increasing concerns about their dependability. This study is a synthesis of existing studies regarding the reliability or generalizability of performance assessments. The meta-analysis involves summarizing, examining, and evaluating research findings. Articles on the dependability…

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 including 96 experimental studies considers the effects of reinforcement/reward on intrinsic motivation. Results indicate that reward does not decrease intrinsic motivation, although interaction effects must be examined. An analysis with five studies also indicates that reinforcement does not harm intrinsic motivation. (SLD)

A framework and concepts for developing inclusion criteria for meta-analysis are presented and illustrated in a meta-analysis of primary studies in patient education for preventive health services. Of 5,451 citations located and abstracts screened, 64 studies eventually met acceptability criteria. (SLD)

A systematic meta-analysis of research studies (N=22) published since 1980 concerning self-concept as a multidimensional phenomenon in children and adolescents was conducted. Results show a complex pattern of gender differences and similarities, some of which were consistent across grade level. Although some of the results defied stereotypes,…

Examines results of Piagetian spatial research studies while focusing on the existence of gender differences in Piagetian spatial assessments. Results indicate that a majority of performance assessments did not demonstrate a significant difference between males and females. Concludes that the clinical interview results provide evidence of the…

This study examines 103 meta-analyses related to educational achievement published over 10 years to produce a meta-synthesis. Various characteristics of the meta-analyses are summarized to produce a methodological profile of research, and effect sizes are synthesized to assess an educational productivity model. (SLD)

This meta-analysis offers decision-makers research-based guidance for intervening with adolescent struggling readers. The authors outline major implications for practice: (1) Adolescence is not too late to intervene. Interventions do benefit older students; (2) Older students with reading difficulties benefit from interventions focused at both the…

As a predominant research method, the mail survey has been the subject of a considerable body of research. Several major reviews of research have been published that attempt to synthesize findings of empirical studies and identify techniques that stimulate responses. The review articles are examined, identifying procedures and potential…

The meta analysis reported in this paper considers the implications of combined correlational evidence for the nature of the relationships of mathematical and spatial skills, and for the possibility that spatial skill underlies gender differences in favor of males on mathematical tasks. In all, 136 studies reported in 116 articles and…

This article is a response to Ruth Wade's meta-analysis of inservice teacher education research in the same issue of "Educational Leadership" (EA 518 308). Factors making a difference in inservice education are identified, but more work needs to be done in understanding the specific, practical details, allowing application. (DCS)

Describes a meta-analysis of 41 studies that looked at effectiveness of continuing medical education (CME) for improving physician knowledge and performance; at influence of CME on patient health status; at variables relating to quality of instructional program design; and at effects of intervening variables and threats to validity in methodology…

This Council on Library and Information Resources (CLIR) report summarizes and analyzes more than 200 recent research publications that focus on the use of electronic library resources (digital libraries and digital resources) and were published between 1995 and 2003. Eight major ongoing studies (each with multiple publications) are identified as…

There exist two types of reviews the Organization for Economic Cooperation and Development (OECD) is conducting, country reviews and thematic reviews. Although all country reviews are also thematic by nature, the focus lies more on one country and the analysis serves the specific needs of the country under review and the other member states as a…

This article provides an integrative review of prevention and intervention studies addressing dropout or school completion described in professional journals. Forty-five intervention studies were coded according to research design, participants, interventions, and outcomes to describe the range of data-based programs and approaches available in…
