The present study addresses the question of whether school leadership matters. It employs second-order meta-analysis to synthesize results from 12 first-order meta-analyses examining school leadership effects published 2003-2019. These meta-analyses collectively examined 512 primary studies published across four decades (1978-2019). Results showed…

Public schools widely use mission statements, and many educational administration programs teach mission statements as a necessary lever for school improvement.

Feedback can be defined by Irons (2008) as "any information, process or activity which affords or accelerates student learning based on comments relating to either formative or summative assessment activities" (p. 7). The current study aims to synthesize quantitative research studies to further explore the impact of feedback on academic…

Learning Forward undertakes periodic updates to the Standards of Learning because educator needs, expertise in the field, and research related to professional learning are continually evolving. In addition, evidence and data are critical to implementing and documenting the results-based professional learning that policy and accountability systems…

Since the standards-based education movement began in the early 1990s, mathematics education reformers have developed and evaluated many interventions to support students in mastering more rigorous content.

This meta-analysis synthesizes results from expository text structure interventions designed to increase comprehension for students in kindergarten to grade 12 published between 1970 and 2013. Twenty-one studies were identified, 19 of which met criteria for a meta-analysis, including 48 studywise effect sizes that were meta-analyzed to determine…

Theoretical approaches and empirical research suggest a decline in the levels of motivational variables and self-esteem among students during the school career. However, precise statements about the magnitude of the change remain elusive. Conducting a meta-analysis of 107 independent longitudinal studies with 912 effect sizes, we found an overall…

A meta-analysis was conducted in this study to synthesize research on technology-enhanced language learning published from 1990 to 2015.

18 qualitative investigations of families of children with disabilities from nondominant communities and their perspectives on home-school partnerships were included in this meta-synthesis. Included studies used a qualitative research design to examine the perspectives of families of children with disabilities from nondominant communities in…

To better understand the impact of using e-books on students' reading outcomes, we conducted a meta-analysis of 14 studies with students in grades K-12 published between 2007 and 2018. Findings revealed an average effect size across all studies and reading outcomes of 0.9 that did not differ significantly from zero. There was also no statistically…

Countless meta-analytic studies document the relation between parental involvement and achievement, but they mostly include studies conducted in the United States where parental involvement is framed as a policy issue. This is the first meta-analytic study focusing on East Asian countries characterized by high achievement levels, a comparatively…
