Researchers have long lamented the lack of research regarding the preparation of school leaders. In response, we offer lessons about school and university partnerships from exemplary professional development school (PDS) research to inform collaborative efforts for leadership preparation. We conducted an extensive literature review of 250 studies…

Alphabet knowledge is a hallmark of early literacy and facilitating its development has become a primary objective of preschool instruction and intervention. However, little agreement exists about how to promote the development of alphabet knowledge effectively. A meta-analysis of the effects of instruction on alphabet outcomes demonstrated that…

Background/Context: There is much current interest in the impact of early childhood education programs on preschoolers and, in particular, on the magnitude of cognitive and affective gains. Purpose/Objective/Research Question/Focus of Study: Because this new segment of public education requires significant funding, accurate descriptions are…

Research on the validity of psychosocial factors (PSFs) and other noncognitive predictors of college outcomes has largely ignored the practical benefits implied by the validity. We summarize evidence of the validity of PSF measures as predictors of college outcomes and then explain how this validity directly translates into improved identification…

Career development research has often explored gender differences in and development of career patterns (Gottfredson, 2006). Hyde's (2005) meta-analysis indicated that men and women shared more similarities than differences. Applying Hyde's gender similarities hypothesis to careers, the authors conducted a 2-stage study. Stage 1 was an analysis of…

One influential hypothesis for what makes teachers effective contends that the best teachers share a particular set of values about education, such as commitment, caring, or persistence. To translate affective beliefs, attitudes, and values into practicable teacher selection, many schools have turned to commercial teacher hiring instruments. This…

Health education researchers have called for research articles in health education to adhere to the recommendations of American Psychological Association and the American Medical Association regarding the reporting and use of effect sizes and confidence intervals (CIs). This article expands on the recommendations by (a) providing an overview of…

Delay discounting (DD), the tendency to prefer smaller, sooner rewards to larger, later ones, is an important indicator of self-control. Assessments of DD superficially require individuals to make choices based on motivational processes. However, several lines of evidence suggest that DD may be systematically related to cognitive ability. We…

This meta-analysis synthesized 102 effect sizes reflecting the relation between specific moods and creativity. Effect sizes overall revealed that positive moods produce more creativity than mood-neutral controls (r = 0.15), but no significant differences between negative moods and mood-neutral controls (r = -0.03) or between positive and negative…

In this meta-analytic study, the authors examined the efficacy of marriage and relationship education (MRE) on 2 common outcomes: relationship quality and communication skills. A thorough search produced 86 codable reports that yielded 117 studies and more than 500 effect sizes. The effect sizes for relationship quality for experimental studies…

In this paper, contemporary literature on strategy in education is examined in an integrative and analytical manner. To achieve this, an empirical investigation on strategy in education was undertaken. As the goal is to understand and propose specific research directions, the findings are both descriptive and analytical. Initially, peer reviewed…

Objective: To clarify the nature and extent of differences in the ways that physically abusive, neglectful, and non-maltreating parents communicate during interactions with their children. Method: A meta-analysis was conducted of 33 observational studies comparing parent-child interactions in families where parents have a documented history of…

A meta-analysis of the stability of low IQ (IQ less than 80) was performed on IQ tests that have been commonly used--tests that were derived by D. Wechsler (1949, 1955, 1974, 1981, 1991, 1997) and those based on the Binet scales (L. M. Terman, 1960; L. M. Terman & Merrill, 1972). Weighted-mean stability coefficients of 0.77 and 0.78 were found…

Problem-based learning (PBL) has been utilized for over 40 years in a variety of different disciplines. Although extensively researched, there is heated debate about the effectiveness of PBL. Several meta-analyses were conducted that provided a synthesis of the effects of PBL in comparison to traditional forms of instruction. This study used a…

Apprenticeships have a very long history in Australia, building on the traditions of the medieval guilds. The essence of the apprenticeship is the contract of training--a legal contract between an individual, an employer and a training provider. The defining characteristic is the combination of employment and training. The purpose of this paper is…
