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…

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…

Designing rigorous studies to identify technology-based interventions to improve K-12 student reading skills require intervention researchers to take a "road less traveled." This chapter presents that road using the Knowledge Acquisition and Transformation Expansions (KATE) intervention as a case study. An early version of KATE has shown…

Practitioner-focused educational doctoral programs have grown substantially in recent years. Dissertations in Practice (DiPs), which are the culminating research report and evaluation method in these programs, differ from traditional PhD dissertations in their focus on addressing a problem of practice and on connecting theories with practice. As…

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…

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…

Typically, parents or other legal guardians are asked for an active declaration that the participation of their child in scientific research is informed and voluntary. However, asking for active parental consent leads to lower quality studies and passive parental consent might be preferable. In this study, we used an online survey in which parents…

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…

Scientific literacy is decreasing in the Czech Republic and inquiry-based science education (IBSE), believed to enhance it, is used rarely. Meanwhile, outdoor teaching is on the rise, but it is unclear if it could help promote inquiry. This study examines the frequencies of outdoor teaching and IBSE and their relationship in self-reported practice…

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…

There is an increasing interest in the integration of computational thinking (CT) in the K-12 curriculum. By integrating CT into other disciplines, the aim is to equip students with essential skills to navigate domain-specific challenges. This study conducts a systematic review of 108 peer-reviewed scientific papers to analyze in which K-12…
