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…

Systematic reviews (SRs) of preclinical studies are marked with poor methodological quality. In vitro studies lack assessment tools to improve the quality of preclinical research. This methodological study aimed to identify, collect, and analyze SRs based on cell culture studies to highlight the current appraisal tools utilized to support the…

This paper advocates for the adoption of Nexus Analysis as a robust analytical framework in Problem-Based Learning (PBL) research. Developed by Scollon and Scollon, Nexus Analysis offers a unique lens for examining the intricate dynamics of PBL by seamlessly integrating micro-level interactions with macrolevel societal discourses. The approach…

Reading is a complex, uniquely human invention for communication through print. It is a critical ability for making progress in education. Students with reading difficulties, the most common learning disability, struggle with reading fluency and accuracy. Skilled reading is enabled by the coordination of a network of brain regions interconnected…

A wide variety of methodological choices and situations can affect the quality of peer nomination measurements but have not received adequate study. This article begins by focusing on systematic nominator missingness as an example of one such situation. We reanalyzed findings from a recent study by Bukowski, Dirks, Commisso, Velàsquez, and Lopez…

This article analyses and discusses dilemmas, ambivalences and problematic issues related to research ethics. This is done firstly by making a distinction between procedural research ethics and particularistic research ethics. Such a distinction reflects a theoretical construction and generalization. In practice, there can be a very close…

The term "creative" is commonly used in everyday language and in academic discourse to discuss the nature of artistic and innovative productions. This usage inherently implies the existence of a variable of creativity that allows different creative works to be compared. The standard definition of creativity asserts that a production must…

In this brief report, we present a scoping review of 31 second language (L2) vocabulary research syntheses published in the Web of Science from January 1990 to May 2022. The purpose of this undertaking was to understand what L2 vocabulary research synthesizers have aggregated and the investigative foci they intended to address. It was observed…

Eight years of data from Grand Valley State University Libraries show a positive correlation between in-class library instruction and student reenrollment the following fall semester. Using consistent statistical methods over time, controlling for confounding factors, and using a large population (N>16,000 annually) and strict protocols that…

This paper explores the prospects of combining Grounded Theory (GT) and Action Research (AR) methodologies to spark further methodological discussion. GT and AR methodologies are sometimes used together in the same study without a discussion of their methodological compatibility. However, different iterations of GT and various forms of AR may…

In this editorial perspective we consider the potential conceptual and empirical overlap between the research on mind wandering, particularly in its pathological extreme, and that on sluggish cognitive tempo (SCT) as it has diverged from research on attention-deficit/hyperactivity disorder (ADHD). The more advanced state of research findings on…

The impact of globalization and technologization has continued to reverberate in the translation industry, causing seismic changes in the translation process, output, and client expectations. Consequently, several approaches and models have been adopted to align training with these changes. Prominent among these is project-based learning, where…

The purpose of this article is to further the methodological cross-fertilization between qualitative social science researchers and psychoanalytic theoreticians by outlining and demonstrating a method of intertextual psychoanalytic-intersubjective analysis (IPIA) in qualitative research. The authors believe that such a bridge between the…

Growing interest in the pathogenesis of autism spectrum disorders (ASDs) and other intellectual and developmental disabilities (IDD) has led to emerging evidence implicating a role for oxidative stress. However, understanding the strength of this association is made challenging by the use of a variety of purported biomarkers of oxidative stress,…

Modern developmental science is informed by several shared principles and adopts a lifespan approach that goes from infancy to senescence. Increasingly, disciplines outside psychology are adopting research frameworks (e.g., fetal origins, developmental origins of health and disease, first 1000 days) that prioritize prenatal experience as a driver…
