Despite overwhelming evidence that gender plays a significant role in the course of numerous psychological disorders, researchers have historically neglected to address gender similarities and differences in their research. Previous reviews of the psychological literature have indicated that personality, psychotherapy, and behavioral psychology…

This article addresses the set of articles in this special issue of "Applied Measurement in Education" and reflects on the issues that underlie the articles. The authors, as a set, represent many of the professionals who have developed and studied the methodological procedures related to instruction-assessment alignment over the past decade. This…

Nearly four decades have passed since the Individuals with Disabilities Education Act (IDEA) ensured access to public education for students with disabilities in the United States. During the years following its introduction, there was a growing recognition that helping students, especially students with disabilities, in their transitions from…

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…

A gender gap in mathematics achievement persists in some nations but not in others. In light of the underrepresentation of women in careers in science, technology, mathematics, and engineering, increasing research attention is being devoted to understanding gender differences in mathematics achievement, attitudes, and affect. The gender…

This thesis explored the history of calculator usage in mathematics classrooms in the United States since 1975 with a focus on the attitudes of parents, educators, and national organizations. The influence of historical events, people, organizations, research, and trends was explored in depth. Studying the changes that calculators have brought to…

Analogous thinking has been commonly discussed as being an inherent and distinguishing characteristic of human cognition (e.g., Gentner, 2010; Goldstone, Day, & Son, 2010; Holyoak, in press; Rittle-Johnson & Star, in press). Gentner (2003) has argued that as part of the human cognitive toolbox, comparison accompanied by the relational language to…

Eighty elected leaders and 388 followers were sampled to test the relationships between leaders' emotional intelligence and the quality of leader-member exchange. Results of the field study found a significant relationship between leaders' emotional intelligence (total) and leader-member exchange quality. Specific subscales of emotional…

A meta-analysis of 69 data sets ( N = 125,308) was carried out on studies that simultaneously evaluate the effects of math and verbal achievements on math and verbal self-concepts. As predicted by the internal/external frame of reference (I/E) model, math and verbal achievements were highly correlated overall (0.67), but the correlation between…

The purpose of this study was to conduct a systematic review of the secondary transition correlational literature to identify in-school predictors of improved postschool outcomes in the areas of education, employment, and/or independent living for students with disabilities. Based on results of this review, 16 evidence-based, in-school predictors…
