Design-based learning (DBL) offers opportunities to support students' content understanding. Previous DBL studies reported different effect sizes by using the data from one participant group. The goal of this study was to conduct a meta-analysis that would give a comprehensive picture of how DBL is connected to student achievement in different…

In many classrooms across the globe, students are expected to comprehend and produce handwritten and computer-generated texts as soon as they start school. As we progress towards digitalisation in education, it has become necessary to understand the effects of writing modality on students' literacy performance and development. The current…

The use of accommodations is often recommended to remove barriers to academic testing among English Learners (ELs). However, it is unclear whether accommodations are particularly effective at improving ELs' test scores. A growing foundation of empirical work has explored this topic. We conducted a meta-analysis that examined several possible…

The current study employed a content analysis approach to analyze and compare argumentation research in K-12 mathematics and science education published on top five academic journals with the highest impact factor from 2010 to 2019. It includes 9 research articles in the field of mathematics education and 77 research articles in the field of…

Over the past two decades, the landscape of research on mathematics teacher educators (MTE) has grown considerably. One particular area of interest has focused on the knowledge needed by MTEs for their work with preservice K-8 teachers (PTs). In an effort to understand this varied landscape, we conducted an extensive review of research on…

With the study reported on here we aimed to synthesise recent quantitative research to specify the effect of inclusive practices on attitudes via meta-analysis. Since attitudes have an integral role in the performance of inclusion programmes, within the scope of the study, the cumulative findings of experimental studies conducted on attitudes…

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…

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 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…

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…

Purpose: The purpose of this article was to systematically review studies that explored associations between specific curricular models, as an essential component of physical education, and to assess how the student outcomes identified in the models aligned with the national standards. Methods: Using the PRISMA guidelines to identify, screen,…

This review examined the relations between grit and academic achievement based on a meta-analysis of 137 studies yielding 156 dependent samples (N = 285,331). Using the robust variance estimation, we found that the correlations of overall grit level with academic achievement were generally weak to moderate (weighted r = 0.19). The correlation of…

Spelling is one of the most challenging areas for students with learning disabilities (LD), and improving spelling outcomes for these students is of high importance. In this synthesis, we examined the effects of spelling and reading interventions on spelling outcomes for students with LD in Grades K through 12. A systematic search of peer-reviewed…
