Children with Specific Language Impairment (SLI) find it effortful to learn to talk and these difficulties can be persistent. Given the importance of language to human behaviour, it is not surprising to find that language difficulties are a risk factor for associated difficulties in other aspects of children's development. This article asks…

Peer tutoring is an instructional strategy that involves students helping each other learn content through repetition of key concepts. This meta-analysis examined effects of peer tutoring across 26 single-case research experiments for 938 students in Grades 1-12. The TauU effect size for 195 phase contrasts was 0.75 with a confidence interval of…

The use of manipulatives to teach mathematics is often prescribed as an efficacious teaching strategy. To examine the empirical evidence regarding the use of manipulatives during mathematics instruction, we conducted a systematic search of the literature. This search identified 55 studies that compared instruction with manipulatives to a control…

Integrating more than 40 years of studies on locus of control (LOC), this meta-analysis investigated whether (a) the magnitude of the relationship between LOC and psychological symptoms differed among cultures with distinct individualist orientations and (b) depression and anxiety symptoms yielded different patterns of cultural findings with LOC.…

"Teaching English in the Two-Year College's" series "What Works for Me" is a unique artifact in the development of composition as a field. In this article, the author claims "What Works for Me" as a valuable genre, a hybrid of new and old disciplinary forms. In the spirit of Derek N. Mueller's "Views from a Distance: A Nephological Model of the…

Augustine and Hemenover (2013) were right to state that meta-analyses should be accurate and generalizable. However, we disagree that our meta-analysis of emotion regulation strategies (Webb, Miles, & Sheeran, 2012) fell short in these respects. Augustine and Hemenover's concerns appear to have accrued from misunderstandings of our inclusion…

This paper outlines the results of a pilot study conducted to determine the impact on grade outcomes and self-efficacy from the incorporation of preparation-homework (pre-hw) in a developmental mathematics classroom. Both quantitative and qualitative data were collected. This study found that those students who reported doing pre-hw significantly…

Since heterogeneity between reliability coefficients is usually found in reliability generalization studies, moderator analyses constitute a crucial step for that meta-analytic approach. In this study, different procedures for conducting mixed-effects meta-regression analyses were compared. Specifically, four transformation methods for the…

Researchers commonly report that families of children with autism spectrum disorder (ASD) experience more parenting stress than families of typically developing (TD) children or those diagnosed with other disabilities [e.g., Down syndrome (DS), cerebral palsy, intellectual disability]. The authors reexamined the research using comparison groups to…

This paper employs meta-analysis to determine the influence of computer-based scaffolding characteristics and study and test score quality on cognitive outcomes in science, technology, engineering, and mathematics education at the secondary, college, graduate, and adult levels. Results indicate that (a) computer-based scaffolding positively…

This systematic review of the relationships between principal characteristics and student achievement was created for educators, administrators, policy-makers, and other individuals interested in a comprehensive catalogue of research on relations between principal characteristics and student achievement. It synthesizes what is known about…

Clinical Question: Do school-age children receiving treatment for speech, language, and/or communication disorders show equivalent benefit from telepractice-based intervention as from on-site intervention as shown by comparable improvement in speech, language, and communication skills across the two treatment platforms? Method: Systematic Review…

The current paper presents a meta-analytic review of the Motivated Strategies for Learning Questionnaire (MSLQ), which consists of fifteen subscales designed from classic social-cognitive learning theories and which is widely used to predict academic performance. Results based on 2158 correlations from 67 independent samples and 19,900 college…

Political skill is a relatively newly articulated construct. Despite its novelty, it has been investigated in a variety of contexts, showing promise not only as a descriptor of several organizational phenomena, but also as a predictor of job performance. Given this status, it seems appropriate to review the empirical literature to this point for…

The positive core construct of psychological capital (or simply PsyCap), consisting of the psychological resources of hope, efficacy, resilience, and optimism, has recently been demonstrated to be open to human resource development (HRD) and performance management. The research stream on PsyCap has now grown to the point that a quantitative…
