The authors provide a template for counseling researchers who are interested in quantitatively aggregating research findings. Meta-analytic studies can provide relevant information to the counseling field by systematically synthesizing studies performed by researchers from diverse fields. Methodologically sound meta-analyses require careful…

Background: Using meta-analytic review techniques, this study synthesized the results of 79 unpublished studies about the nature of transformational school leadership (TSL) and its impact on the school organization, teachers, and students. This corpus of research associates TSL with 11 specific leadership practices. These practices, as a whole,…

Systematic reviews and meta-analysis are techniques for synthesizing primary empirical studies to produce a summary of effects. To facilitate this goal, the Campbell Collaboration (C2) supports reviews within the disciplines of crime and justice, education, international development, and social welfare. At the annual Campbell Colloquium, experts…

In this introduction to the applicaton of meta-analysis as a quantitative synthesis technique, several alternative approaches to research synthesis are described. Their advantages and disadvantages, as compared to those of the techniques of meta-analysis. Decisions that must be faced by the prospective user of meta-analysis are described.…

This monograph provides a portrait of non-tenure-track faculty, describes studies of their experiences, and proposes plans of action. Much of the research, particularly early on, tried to provide a picture and description of this faculty that have been largely invisible for years. Therefore, "Portrait of Non-Tenure-Track Faculty" focuses on the…

The need for research synthesis is explored as well as the benefits of meta-analysis, particularly those related to understanding and explanation. The problems with traditional review methods are discussed, with special relevance to their failure to resolve problems. Finally, the findings from several meta-analyses are summarized and contrasted…

Several developments in the use of the new method of meta-analysis give cause for optimism. First, different meta-analysts are doing work in the same areas, leading to increased confidence in meta-analytic results. Second, meta-analysts are beginning to include raw data in their reports, which helps readers pinpoint the exact studies that lead to…

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)

Methods for meta-analysis have evolved dramatically since Gene Glass first proposed the term in 1976. Since that time statistical and nonstatistical aspects of methodology for meta-analysis have been developing at a steady pace. This guide is an attempt to provide a practical introduction to rigorous procedures in the meta-analysis of social…

Forty studies using one or more components of Lozanov's method of suggestive-accelerative learning and teaching were identified from a search of all issues of the "Journal of Suggestive-Accelerative Learning and Teaching." Fourteen studies contained sufficient statistics to compute effect sizes. The studies were coded according to substantive and…
