Principal leadership has been widely regarded as a powerful catalyst for school improvement and student learning. This article presents a multivariate meta-analysis of 42 empirical studies, published between 2000 and 2020, that examined the effects of principal leadership on student achievement in the United States. The focus is on the conceptual…

Well-chosen covariates boost the design sensitivity of individually and cluster-randomized trials. We provide guidance on covariate selection generating an extensive compilation of single- and multilevel design parameters on student achievement. Embedded in psychometric heuristics, we analyzed (a) covariate "types" of varying…

The aim of this study is to review the studies conducted on school-aged children in Türkiye between 2000 and 2023 based on the McMaster Family Functioning Model. In this study, a systematic review method was used and the studies that used the McMaster Family Assessment Device as a measurement tool were found through academic search engines. A…

In a recent article in this journal, Sciffer, Perry, and McConney identify the risk of relying on insufficient within-unit variation as a serious flaw in a number of studies using student fixed effects regression to identify the effects of school socioeconomic composition (school SES) on academic achievement, including one by Armor, Marks, and…

In this analysis, the authors describe current approaches to assessing the effectiveness of math curricula and identify potential opportunities to further tailor effectiveness studies to the needs of the practitioners who rely on the research to make adoption decisions. Through analysis of 61 effectiveness studies, supplemented by expert…

This study aims to examine the effects of flipped learning on L2 students' overall academic achievements through meta-analysis. Forty studies (e.g., journal articles, M.A/Ph.D. theses and conference papers) on 'flipped classroom', 'flipped learning' and 'academic achievement' were included in this meta-analysis study. The data was analyzed by…

In this article we reviewed literature related to creative self-efficacy in the field of education. We narrowed down the review to eighty-eight articles. We formed categories according to (1) publication year, (2) country of study, (3) sample/study group, (4) method used, and (5) subject matter addressed. The first study was published in 2004. The…

The aim of the present study was to scrutinize how teacher expectations are shaped and reflected in teachers' classroom behaviors by presenting a holistic picture of teacher expectation literature that has significantly developed since 1968. To achieve this, a systematic review design was utilized in the study, and different academic databases,…

This second-order meta-analysis (i.e., systematic quantitative synthesis of individual meta-analyses) summarises how the use of technology affects learning (achievement outcomes) in three different educational settings: in-class, online learning and blended learning. Comprehensive literature searches identified 915 potentially relevant…

Charter schools are highly debated in policy and political discussions about delivering public education. As "laboratories of innovation" that often use lotteries to assign spots, they hold the potential to generate rigorous evidence about effective educational practices. This paper synthesizes and summarizes findings from charter…

This article synthesizes observation studies investigating reading instruction for students with learning disabilities (LD) in Grades K-12. A systematic search of the literature between 1980 and 2014 resulted in the identification of 25 studies. In addition to replicating and extending E. A. Swanson's synthesis, the research questions of studies…

This report summarizes the methodology, measures, and findings of research on the influence on student achievement outcomes of K-12 online and blended face-to-face and online learning programs that offer differentiated learning options. The report also describes the characteristics of the learning programs. Most of the examined programs used…

This document contains the appendixes for the full report, "Teacher Turnover and Access to Effective Teachers in the School District of Philadelphia".

Some researchers have characterized Universal Design for Learning (UDL) as a promising framework to provide diverse students with access to the general education curriculum, but to what extent and how have UDL-based interventions fulfilled that promise? The purpose of this review was to analyze studies that investigated impacts of UDL-based…
