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…

Motivation to read is a central consideration for teachers and researchers because it is strongly associated with reading performance and is generally accepted as a positive state. The study of reading motivation is plagued by inconsistent terminology and measurement, which impedes a comprehensive knowledge base for teachers and researchers. One…

Research on the digital divide in sub-Saharan education needs an overview of its conceptual developments and practices since the studies in the field of the digital divide emerged and were established around the mid-1990s. The present systematic literature review fills such a gap by using mixed methods to analyse three aspects of research on the…

Many teacher education researchers have expressed concerns about the lack of rigorous impact evaluations of teacher preparation practices. I summarize these various concerns as they relate to issues of internal validity, measurement, and external validity. I then assess the prevalence of these issues by reviewing 166 impact evaluations of teacher…

Background: There are many examples of school-based interventions involving a service learning project aimed at helping students with disabilities, but it is potentially more impactful on the students with disabilities for them to be active participants in service learning, rather than merely its recipients. Purpose: The purpose of this article is…

In order to produce the most reliable syntheses of the effectiveness of educational interventions, systematic reviews need to adhere to rigorous methodological standards. This meta-review investigated risk of bias occurring while conducting a systematic review and the presence of open science practices like data sharing and reproducibility of the…

The adoption of the maker-centered method is gaining popularity in K-12 school curricula. However, a unified consensus on its effectiveness in enhancing K-12 students' learning outcomes remains elusive. Therefore, the purpose of this meta-analysis was to synthesize the findings on the overall effects of the maker-centered learning method on K-12…

Research and theory indicate that the type and quality of instruction, not the delivery mechanism, are what impact learning. Previous reviews have not systematically explored variations in the instructional strategies, approaches, and designs of educational technology programs and also suffered from lax inclusion criteria, which has been known to…

The aim of this study was to collect and analyze research on inclusive education from the perspective of parents of students with intellectual disability (ID). The review examined characteristics and trends related to geographical origin of research, design, data collection, publication source and year, source of data, age of individuals with ID,…

As the field of K-12 data science education continues to take form, humanistic approaches to teaching and learning about data are needed. Data feminism is an approach that draws on feminist scholarship and action to humanize data and contend with the relationships between data and power. In this review paper, we draw on principles from data…

Researchers' reliance on using mixed methods for in-depth understanding of a phenomenon is on a rise. This review provides a synthesis of studies using Mixed Methods Research (MMR) approach in the field of instructional design, with a particular focus on research questions. The results show that of the 752 articles published on MMR in the…

Concept maps have been used widely in various subjects of K-12 and higher education for diverse purposes. Digital concept maps (DCM) provide even more benefits, such as higher efficiency, expanded canvas, and multimedia integration. The present paper sought to analyze the research and application trends and issues in DCM research and practices…

Although there is a notion of a 'Nordic tradition' of outdoor education in the international literature, research from the Nordic countries is rarely included in research reviews. Therefore, this scoping review provides an overview of empirical studies on outdoor education (grades 1-13) from the Nordic countries. Of the 586 hits, 52 studies met…

Repeated reading (RR) is an established and extensively researched intervention which has been shown to improve reading fluency and comprehension. However, past reviews have found the rigor of the RR research insufficient for it to be considered evidence-based. Previous review of the RR research were updated and expanded. Forty-four group designs…
