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…

Ruth Wade replies to an article written by Georgea Sparks in the same issue of "Educational Leadership" (EA 518 309) as a response to Wade's meta-analysis of inservice teacher education also appearing in this issue (EA 518 308). A closer look at the major findings is needed. (DCS)

This paper highlights the relative strengths and weaknesses of the contemporary methods of research synthesis and proposes a multistage approach to research synthesis that draws on the strengths of each of these individual methods. In this approach, the decisions at every step of the synthesis process are guided by the nature of the data. The…

Presents meta-analysis evidence of the association between paternal sensitivity and infant-father attachment from eight studies with 546 families (combined effect size r = 0.13). A meta-analysis of 950 families from 14 studies found an overall correlation of 0.17 between infant-mother and infant-father attachment. Presents a data-based model of…

Arguments supporting the use of the exploratory case method in evaluating reviews of multivocal literature are repeated, and points of general agreement with M. Q. Patton and R. F. Elmore are reviewed. Disagreement is expressed with R. K. Yin about the value of grounded theory in analyzing multivocal literature. (SLD)

Argues that there are two central reasons for concern about the adequacy of M. Allen's metanalysis of the research literature concerning the relative persuasive effectiveness of one-sided and two-sided messages: (1) the classification of the message types in a number of studies is questionable; and (2) the literature search underlying the review…

Responds to an analysis by D. O'Keefe (in the same issue of this journal) of a research study by the author. States that most of what O'Keefe suggests contains merit but that acceptance of the suggestions still generates a conclusion that two-sided refutational messages constitute the most persuasive form of message.

Discusses issues inherent in the four meta-analyses of instructional interventions for students with learning disabilities conducted by Gersten and Baker, MacArthur et al; Elbaum and Vaughn, and Swanson. Considers the effects of meta-analyses in general on practice, the effect of including studies that do not meet methodological criteria, and…

Discussion of the need for systematic methods for summarizing single-participant research describes various approaches for quantitative synthesis and reviews conclusions of completed synthesis efforts. The issue of whether outcomes of single-participant research can be represented by a single common metric is addressed with the recommendation that…

In their article "Scholars Before Researchers: On the Centrality of the Dissertation Literature Review in Research Preparation", David N. Boote and Penny Beile argue that the literature review is the fundamental task of dissertation and research preparation. They claim that doctoral students receive minimal formal training, and little guidance…

Studies of memory impairment in humans and experimental animals have been fundamental to learning about the organization of memory and its cellular and molecular substrates. When memory impairment occurs, especially after perturbations of the nervous system, the question inevitably arises whether the impairment reflects impaired information…

The original authors respond to a critique of their meta-analysis of 94 studies which had failed to support the presence of distinctive Wechsler Intelligence Scale for Children profiles for learning disabled children. The critique contended such a pattern does exist. (Author/DB)

As part of a continuing dialog concerning the validity of a meta-analysis of 94 studies suggesting that there is a lack of any distinctive pattern in the Wechsler Intelligence Scale for Children (Revised) profiles for learning disabled children, this article maintains the view that such differences do exist. (DB)

The commentator finds that Slavin's synthesis is limited by its failure to distinguish between school and classroom organization and classroom instruction as well as the lack of consideration of intervening circumstances. (SLD)

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)
