Many public and private initiatives have focused on improving prekindergarten (PK) through Grade 12 mathematics education, given that the mathematics content learned before college is foundational for later learning and college success across STEM subjects. Although decades of educational research have studied PK-12 mathematics interventions, the…

Thousands of educational apps are available to students, teachers, and parents, yet research on their effectiveness is limited. This meta-analysis synthesized findings from 36 intervention studies and 285 effect sizes evaluating the effectiveness of educational apps for preschool to Grade 3 children and the moderating role of methodological,…

We examined the relation of morphological awareness with language and literacy skills, namely phonological awareness, orthographic awareness, vocabulary, word reading, spelling, text reading fluency, and reading comprehension. We also examined potential moderators of the relations (grade level, orthographic depth of language, receptive vs.…

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…

This paper is a quantitative synthesis of research on home literacy environment (HLE) and children's English as a second language (ESL) learning outcomes through a meta-analysis of 18 articles in kindergarten, primary, and secondary school students (N = 4401) carried out between 2000 and 2018. It examines the associations between HLE factors and…

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…

This meta-analysis synthesized research on math performance outcomes for English learners (EL) as a function of language-focused (math vocabulary) interventions. We included group and single-subject design studies with children from kindergarten to 8th grade (3,766 students for group, 30 for single-subject). Group studies yielded a mean Hedges' g…

There is a rich body of studies on the implementation problems of curricular changes comprising more student-centred methodologies in English as a foreign language education around the world. Focusing on these global-wide studies within the context of the Ecological System Theory, this meta-synthesis aims to identify the common factors that hinder…

The purpose of this meta-analytic review was to investigate the relation between motivation and reading achievement among students in kindergarten through 12th grade. A comprehensive search of peer-reviewed published research resulted in 132 articles with 185 independent samples and 1,154 reported effect sizes (Pearson's r). Results of our…

Background/Context: Despite the surge in efficacy studies, a recent meta-analysis indicates that the relative effectiveness of any two math interventions is largely unknown (Nelson & McMaster, 2019). Additionally, policy makers rarely choose educational programs based on an assessment of costs and cost-effectiveness (Hollands et al., 2016;…

A recent national report heartily supported arts integration as an effective, innovative, and cost-efficient way to address teachers' and students' needs; however, the report called for a better understanding of when, for whom, and what content areas are best served by arts integration methods. The effectiveness of drama-based pedagogy (DBP), a…

This article presents the results of a meta-analysis of the effects of school-based interventions for improving disability awareness and attitudes towards disability of students without disabilities in Kindergarten through secondary school grades in the Republic of Korea (South Korea). A total of 20 studies published between 2001 and 2017 were…

Methods for meta-analyzing single-case designs (SCDs) are needed to inform evidence-based practice in clinical and school settings and to draw broader and more defensible generalizations in areas where SCDs comprise a large part of the research base. The most widely used outcomes in single-case research are measures of behavior collected using…

Empirical studies investigating supplemental reading interventions for students with or at risk for reading disabilities in the early elementary grades have demonstrated a range of effect sizes. Identifying the findings from high-quality research can provide greater certainty of findings related to the effectiveness of supplemental reading…
