The purpose of this study was to investigate the effectiveness of four different models (bifactor, CTC(M-1), CTCU and unidimensional) as to optimal model selection when the wording effect associated with negatively worded items was present. A Monte Carlo simulation study was conducted to compare model-data fit and accuracy in parameter estimates…

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…

This article ponders the question: "How might EdD research methods courses be reimagined to position Black Feminist Theory as a comparable theoretical framework to guide epistemological stance development and scholar-practitioner inquiry?" By introducing Black Feminist Theory as a viable theoretical framework, this article posits its…

The COVID-19 pandemic caused tremendous upheaval in schooling. In addition to its devasting effects on students' academic development, the disruptions to schooling had important consequences for researchers conducting effectiveness studies on educational programs during this era. Given the likelihood of future large-scale disruptions, it is…

Single case experimental designs are an important research design in behavioral and medical research. Although there are design standards prescribed by the What Works Clearinghouse for single case experimental designs, these standards do not include statistically derived power computations. Recently we derived the equations for computing power for…

David Clarke's research has shifted the focus of classroom research in mathematics education from study of cultural patterns to study of patterns of participation and the learning that can result in highly complex social environments. His Complementary Accounts Methodology which informed the Learner's Perspective Study design included multi-source…

This article addresses the debate on pre-evaluative choices of impact depictions and the forms of responses between applicants and funders. By adopting a reflexive perspective on the social impact of social sciences, this article explores researchers' vocabularies in the research proposals and mid-term reports of consortiums during the Strategic…

A student within a university's Ed.D. program is encouraged by her director to narrow her research focus; however, her interests in Curriculum Studies, Arts-Based Educational Research, and Composition Studies led her to design a practitioner action research study examining intersections between the fields. As she collected participants' data, she…

Although numerous meta-analyses of single-case design (SCD) research have been published, no systematic review has been conducted to holistically reveal the trends in content focus, and the state-of-the-art practices in conducting SCD meta-analyses for school-aged students with autism spectrum disorder (ASD). This study synthesized the…

Background: Research outcomes on intellectual development and related disabilities in North Korea are not widely known. Therefore, the current scoping review aimed to provide preliminary insight on research topics concerning intellectual disabilities in North Korea. Method: A six-stage framework for scoping review was adopted to examine research…

Criteria are briefly proposed for final conclusions, research problems, and research hypotheses in quantitative research. Moreover, based on a proposed definition of applied and basic/general research, it is argued that (1) in applied quantitative research, while research problems are necessary, research hypotheses are unjustified, and that (2) in…

Studies using co-design methods require the meaningful involvement of stakeholders in creating new knowledge and harnessing, mobilising, and transferring existing knowledge to support comprehensive and long-term solutions. In the health sector, co-design methodology is seen as a way of supporting and engaging local communities in critical…

Mixed methods research (MMR) designs are well suited for answering policy-relevant questions, yet they remain underutilized in public policy and public administration scholarship. To provide a deeper understanding of the effective use of such designs, this article examines the prevalence of MMR in public policy and public administration journals,…

The purpose of this article is to identify proper uses for mixed methods in leadership research and assessment. This article will highlight research and assessment questions that are best served by mixed methods and will offer practitioner-friendly guides and examples for integrating quantitative and qualitative data to help eat the whole whale…

Optimal design of multisite randomized trials leverages sampling costs to optimize sampling ratios and ultimately identify more efficient and powerful designs. Past implementations of the optimal design framework have assumed that costs of sampling units are equal across treatment conditions. In this study, we developed a more flexible optimal…
