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…

Recent critiques of physics education research (PER) studies have revoiced the critical issues when drawing causal inferences from observational data where no intervention is present. In response to a call for a "causal reasoning primer" in PER, this paper discusses some of the fundamental issues in statistical causal inference. In…

Student engagement is one of the most promising concepts in educational research today, as it has been positively correlated to a host of desirable outcomes and negatively correlated to a variety of undesirable outcomes. While there has been tremendous progress in advancing our understanding of student engagement including the developing of…

Multilevel structural equation models (MSEM) are typically evaluated on the basis of goodness of fit indices. A problem with these indices is that they pertain to the entire model, reflecting simultaneously the degree of fit for all levels in the model. Consequently, in cases that lack model fit, it is unclear which level model is misspecified.…

Background: Teacher instructional competency, the set of essential knowledge and skills needed to guide teaching practice, is critical to the successful implementation of school health education. The purpose of this paper is to introduce the Health Education Teacher Instructional Competency (HETIC) framework, a new conceptualization describing…

The construct of identity is increasingly recognized as a dominant and determining aspect in learning mathematics. While researchers--collectively--theorize identity as situated and negotiated, they also draw attention to the unwieldy nature of the concept that makes it difficult to define and operationalize. The purpose of this paper is to…

Parallel to the increasing level of maturity of the field of research on higher education, an increasing number of scholarly works aims at synthesising and presenting overviews of the field. We identify three important pitfalls these previous studies struggle with, i.e. a limited scope, a lack of a content-related analysis, and/or a lack of an…

The aim of this research was to examine graduate thesis studies conducted in the field of special education in Turkey about special education teachers in terms of various variables. In the thesis scanning center of the Council of Higher Education Center (YOK), it was determined that 89 graduate thesis studies in the special education field were…

The article draws attention to the forgotten ancestry of the "four steps of comparison" model (description--interpretation--juxtaposition--comparison). Comparativists largely attribute this to George Z. F. Bereday [1964. "Comparative Method in Education." New York: Holt, Rinehart and Winston], but among German scholars, it is…

Researchers commonly interpret effect sizes by applying benchmarks proposed by Cohen over a half century ago. However, effects that are small by Cohen's standards are large relative to the impacts of most field-based interventions. These benchmarks also fail to consider important differences in study features, program costs, and scalability. In…

With a growing interest in research on educational processes, there is a need to overview suitable latent variable models for students' learning experiences in real-time. This tutorial provides an introduction to intraindividual (multilevel) structural equation models (ISEM) for the analysis of process data (e.g. intensive longitudinal,…

A century on from the height of John Dewey's educational writings and the reputation of the Gary Schools Plan as a model of progressive education, the paper reappraises two key matters: the relationship between John Dewey and William Wirt, the first superintendent of the Gary Schools in Gary Indiana, and the coherence between John Dewey's…

In educational contexts where many domains subject to improvement are interdependent and causal evidence is frequently lacking it is difficult, if not impossible, for policymakers and educational practitioners to decide which domain should be invested in. This paper proposes a new method that uses Conditional Mean Independent Correlations (CMIC)…

The concept of bidirectionality represents a process of mutual influence between parent and child, whereby each influences the other as well as the dyadic relationship. Despite the widespread acceptance of bidirectional models of influence, there is still a lack of integration of such models in current research designs. Research on…

Schools have poor reputation among creativity researchers. Teachers' biases and implicit theories, disruptive behaviors among creative students, and the equivocal pattern of the relationship between creativity and school achievement all contribute to this fact. This chapter presents a new typological model of creativity and demonstrate how this…
