Understanding the abstract principles of statistical experimental design can challenge undergraduate students, especially when learned in a lecture setting. This article presents a concrete and easily replicated example of experimental design principles in action through a hands-on learning activity for students enrolled in an experimental design…

Background: Power analysis and sample size planning are key components in designing cluster randomized trials (CRTs), a common study design to test treatment effect by randomizing clusters or groups of individuals. Sample size determination in two-level CRTs requires knowledge of more than one design parameter, such as the effect size and the…

We examine how the politics of knowledge production limit research on the relationship between immigration status and social inequality. We centre the practices of methodological nationalism in Canada, a traditional country of permanent immigration in which temporary migration has become a core feature of the immigration system. In this case,…

Background: Allen, Fielding, East, et al. demonstrated experimentally that structural awareness, or the ability to disregard a research problem's topic and instead focus on its structural features, can be trained using StatHand (https://stathand.net). Most training benefits persisted for 1 week. Objective: The objective was to assess the…

Parents of children who are deaf or hard of hearing have long attracted interest from researchers, though, since the 1990s, published research about this population has increasingly gravitated toward issues surrounding pediatric cochlear implantation. This scoping review was undertaken to map the nature, extent, and range of three decades of…

To better understand the existing research for teaching workplace social skills to individuals with severe disabilities, we conducted a systematic review of the literature across five databases between the years 1975 and 2020. This review examined study characteristics, intervention efficacy, and methodological soundness. We identified a total of…

Many experimental designs in educational and behavioral research involve at least one level of clustering. Clustering affects the precision of estimators and its impact on statistics in cross-sectional studies is well known. Clustering also occurs in longitudinal designs where students that are initially grouped may be regrouped in the following…

Purpose: This study aims to examine how case study research has been applied in the field of human resource development (HRD). Design/methodology/approach: The authors examined HRD case study research by analyzing 118 refereed, empirical case study articles published between 2000 and 2020 in three Academy of HRD-sponsored journals. Findings:…

This essay focuses on a particular subset of educational research, questions that are researchable and that, ultimately, will make a positive difference for the educational enterprise. It argues that to be researchable, tasks need to be addressable in operational terms -- that questions that hinge on values (e.g. "are large small classes…

Recent years have witnessed a host of innovations for conducting research with qualitative comparative analysis (QCA). Concurrently, important issues surrounding its uses have been highlighted. In this article, we seek to help users design QCA studies. We argue that establishing inference with QCA involves three intertwined design components:…

The purpose of the study is to discuss accurate and effective data collection for qualitative studies. The analysis of the written documents for the study was carried out via the descriptive analysis approach. Many documents reviewed, checked for authenticity, arranged, and organized by field experts can be a source of data, and using these…

A randomized experiment that measures the impact of a social policy in a sample of the population reveals whether the policy will work on average with universal application. An experiment that includes only the subset of the population that volunteers for the intervention generates narrower "proof-of-concept" evidence of whether the…

We conducted a systematic literature review examining the participant characteristics of studies of students with emotional disturbance (ED) with the purpose of better understanding potential similarities and differences between students with ED in research and the population of students with ED. Results indicate (a) participants with reported…

Introduction: Psychological science is undergoing a period of change and transformation. Statement of the Problem: The crisis in confidence over psychological science has led to an emphasis on larger and larger sample sizes, sustaining an unfortunate neglect of single-subject research designs in undergraduate education. Literature Review: We…

Designed to be used as a primary text in introductory research methods courses, "Music Education Research: An Introduction" aims to orient even the most novice researchers toward basic concepts and methodologies. Offering sustained attention to historical, philosophical, qualitative, quantitative, and action research approaches, the book…
