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…

The purpose of this dissertation is to develop principles and strategies for and identify limitations of multisite cluster randomized trials in the context of partially and fully nested designs. In the first study, I develop principles of estimation, sampling variability, and inference for studies that leverage multisite designs within the context…

Single-case research designs (SCRDs) are rigorous methods used to investigate the effects of interventions on socially important outcomes. A hallmark of SCRDs is repeated measurement of observable behavior presented in time-series graphs. The construction of time-series graphs can inflate Type I or Type II errors made via visual analysis. In the…

This systematic literature review critically evaluates 14 empirical studies published over a 14 years span (2006-2019) to answer questions about the models and the effects of transformational school leadership on student academic achievement. The analysis of the related literature utilized vote counting and narrative synthesis to delineate the…

Comprehensive evaluation of treatment effects is aided by considerations for moderated effects. In educational research, the combination of natural hierarchical structures and prevalence of group-administered or shared facilitator treatments often produces three-level partially nested data structures. Literature details planning strategies for a…

Scholarly efforts to identify core design features for effective teacher professional development have grown rapidly in the last 25 years. Many concise lists of design principles have emerged, most of which converge on a consensus of 5-7 presumably 'effective' features (e.g. collaborative tasks, active learning, focus on content). The…

Sample size and statistical power are important factors to consider when planning a research synthesis. Power analysis methods have been developed for fixed effect or random effects models, but until recently these methods were limited to simple data structures with a single, independent effect per study. Recent work has provided power…

This article presents marketing educators with an approach to teaching an undergraduate services marketing class with a unique emphasis on service design. As part of the class, the content on services marketing fundamentals is blended with a detailed discussion of service design. Additionally, hands-on experience with the service design process is…
