This article presents a meta-analytic review of the relation between executive function and reading comprehension. Results (N = 6,673) supported a moderate positive association between executive function and reading comprehension (r = 0.36). Moderator analyses suggested that correlations between executive function and reading comprehension did not…

The "Q" test is regularly used in meta-analysis to examine variation in effect sizes. However, the assumptions of "Q" are unlikely to be satisfied in practice prompting methodological researchers to conduct computer simulation studies examining its statistical properties. Narrative summaries of this literature are available but…

Purpose: Instructional leadership has assumed steadily increasing importance within the general role set of principals over the past 60 years. One persisting finding within this corpus of studies concerns the consistently higher ratings obtained by female principals on instructional leadership when compared with their male counterparts. This…

This meta-analysis provides an extensive and organized summary of intervention studies in education that are grounded in motivation theory. We identified 74 published and unpublished papers that experimentally manipulated an independent variable and measured an authentic educational outcome within an ecologically valid educational context. Our…

The current study employed a meta-analytic approach to investigate the relative importance of component reading skills to reading comprehension in struggling adult readers. A total of 10 component skills were consistently identified across 16 independent studies and 2,707 participants. Random effects models generated 76 predictor-reading…

Problem Statement: A number of recent studies on constructivism that have been conducted separately (independently) have arrived at very different results. Throughout the ten-year period in which the constructivist approach has been applied, there have been studies that have researched the effect of the newly-introduced approach on student…

The improvement of computing courses is a permanent need and is a goal established by any teacher. Suggestions of possible course improvements should be made by teachers and students. Computer project-based courses involving a significant number of people pose difficulties to listening to all their opinions. The purpose of our research is twofold:…

The Council of Chief State School Officers (CCSSO) was awarded a grant from the National Science Foundation to conduct a meta analysis study with the goal of providing state and local education leaders with scientifically-based evidence regarding the effects of teacher professional development on improving student learning. The analysis focused on…

Reviews entities that can be factored, with emphasis on Q-technique analyses. Explains basic rationale for Q-technique factor analysis, offers guidelines regarding use of Q-technique factor analysis, presents studies to illustrate applications of Q-technique factor analysis, and discusses special considerations with regard to Q-technique factor…

In order to discover how the photographic medium has been conceptualized, a study examined all books published in the United States from 1902 to 1960 which are part of the intellectual response to photography and a sample of the periodicals which concern themselves with photography. A critical review of the literature combined with Q methodology…

Reviews literature on Q-sort in gerontological research. Argues that the measurement of self-concept and the design of outcome measures with elderly clients should emphasize: (1) multiple, interactive determinants of life-span development; (2) increases in intraindividual variability/interindividual differences with age; (3) ecological validity;…

There has been very little discussion of the issues in developing an occupational card sort despite the growing interest in this technique. Discusses these issues as they arose in developing an occupational card-sort system, known as Occu-Sort, and describes how card-sort developers have resolved them. (Author)

The increasingly use of technology in education does set off a flurry of research studies that focus on the successfulness and effectiveness of technology in elementary and secondary education. In this study, we conducted a comprehensive meta-analysis of research literature on technology in relation to mathematics teaching and learning.…

Q methodology, a theory-based research technique begun by William Stephenson, permits a scientific approach to the study of subjective ideas, and proves useful in studying intrapersonal communication processes in a variety of contexts. The Q-sort, which incorporates Q methodology into a measure, allows respondents to sort statements (pictures or…

Used meta-analysis to examine premise that the early child-parent bond is reflected in interpersonal relationships across the life span. Found that overall effect size (ES) for child-mother attachment was small to moderate. ESs were similar in studies using Strange Situation and Q-sort methods. ESs were larger for middle childhood and adolescent…
