A meta-analysis of randomized, controlled trials of social skills training for schizophrenia was conducted. Outcome measures from 22 studies including 1,521 clients were categorized according to a proximal-distal continuum in relation to the presumed site of action of skills training interventions, with content mastery tests and performance-based…

At the core of higher education is the experience of students whose focus for learning is often directed towards their future employability. In this paper, we explore the intersections between two large international research projects involving over 500 students. Interviews with students yielded their conceptions of learning and work in specific…

We review significant empirical studies of the arithmetic abilities of children with dyslexia. These studies suggest that the academic impairments of children with dyslexia are not limited to reading and spelling, but also include aspects of mathematics. A consistent finding across a number of studies is that children with dyslexia have difficulty…

This study is a meta-interpretative analysis that focuses on research conducted and published by other researchers. Concepts central to this study include global practical relevance, curriculum design, and formative situation. We analyzed 35 studies selected from 374 published studies in the years 2000 and 2001 in three journals referenced in the…

Despite the growing number of collaborations between volunteers and professional scientists, research efforts investigating the impacts of such collaborations, which we have termed Public Participation in Scientific Research (PPSR), have been very limited. Examples of PPSR projects include citizen science, volunteer monitoring, and participatory…

The past two decades have seen an emerging trend in urban school governance: mayors taking the reins of school district leadership. The impetus for putting the mayor in charge of a city's schools usually stems from at least one of the following being documented or generally perceived about an urban school district: (1) Lack of accountability; (2)…

This meta-analysis of the experimental literature of distance education (DE) compares different types of interaction treatments (ITs) with other DE instructional treatments. ITs are the instructional and/or media conditions designed into DE courses, which are intended to facilitate student-student (SS), student-teacher (ST), or student-content…

Peer review is valued in higher education, but also widely criticized in terms of potential biases, particularly gender. We evaluate gender differences in peer reviews of grant applications, extending Bornmann, Mutz, and Daniel's meta-analyses that reported small gender differences in favor of men (d = 0.04), but a substantial heterogeneity in…

A systematic literature search for studies reporting effects of Early Intensive Behavioral Intervention identified 34 studies, 9 of which were controlled designs having either a comparison or a control group. We completed a meta-analysis yielding a standardized mean difference effect size for two available outcome measures: change in full-scale…

An initial research step, developing an effective interview strategy, presents unique challenges for novice and master research alike. To focus qualitative research in the human ecology of the study, the strategy presented in this paper used an initial interview protocol and preanalysis process, called meta-analysis, prior to developing the formal…

Reliability generalization (RG) is a measurement meta-analytic method used to explore the variability in score reliability estimates and to characterize possible sources of the variance. Summarizes some RG considerations, and suggests how confidence intervals might be portrayed graphically. (SLD)

Used reliability generalization to study five versions of the Working Alliance Inventory (A. Horvath, 1981; WAI), analyzing 67 internal consistency estimates, 6 interrater reliability estimates, and 4 study characteristics. In general WAI scale scores appear to be robust. (SLD)

Focusing on psychotherapy research, illustrates methods for studying mediator and moderator variables in meta-analysis, discusses their advantages and disadvantages, and shows how inclusion of these variables can change interpretation of meta-analytic results. Notes that therapeutic orientation may make significant difference to outcome but only…

Discusses two estimators of the variance of random effects models often used in meta-analysis. Provides mathematical proof that the second, less intuitively appealing, estimator is more efficient when the variance of the random effects model is small. (SLD)

The relationship between brain volume and intelligence has been a topic of a scientific debate since at least the 1830s. To address the debate, a meta-analysis of the relationship between in vivo brain volume and intelligence was conducted. Based on 37 samples across 1530 people, the population correlation was estimated at 0.33. The correlation is…
