Pre-registration refers to the practice of researchers preparing a time-stamped document describing the plans for a study. This open research tool is used to improve transparency, so that readers can evaluate the extent to which the researcher adhered to their original plans and tested their theory appropriately. In the current study, we conducted…

Introduction: Missing data are bound to occur in education intervention research. Reasons vary but always have the consequence of reducing sample sizes and can, under certain conditions, seriously bias estimated intervention effects. A wide array of methods have been developed for handling missing data (Enders, 2023). Whereas older approaches…

Background: Power analyses for a cluster-randomized trial (CRT) require estimates of additional design parameters beyond those needed for an individually randomized trial. In a 2-level CRT, there are two sample sizes, the number of clusters and the number of individuals per cluster. The intraclass correlation (ICC), or the proportion of variance…

Outside of education, many academic disciplines developed and promulgated checklists to evaluate the quality of qualitative studies. This article used an embedded mixed methods approach in three stages: development of a conceptual framework reviewing 62 guidelines; a content analysis of key areas of the guidelines; and review of dissertations to…

Context: A perennial problem in applied statistics is the inability to justify strong claims about cause-and-effect relationships without full knowledge of the mechanism determining selection into treatment. Few research designs other than the well-implemented random assignment study meet this requirement. Researchers have proposed partial…

N-of-1 trials, a special case of Single Case Experimental Designs (SCEDs), are prominent in clinical medical research and specifically psychiatry due to the growing significance of precision/personalized medicine. It is imperative that these clinical trials be conducted, and their data analyzed, using the highest standards to guard against threats…

Manipulation checks are an essential component of quality experimental design in motor learning. Guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework, this methodological systematic review examined the utilization of manipulation checks in focus of attention research. Seventy-eight protocols from four…

Meta-analytic reviews collect available empirical studies on a specified domain and calculate the average effect of a factor. Educators as well as researchers exploring a new domain of inquiry may rely on the conclusions from meta-analytic reviews rather than reading multiple primary studies. This article calls for caution in this regard because…

Academic advising is one of the key practices in U.S. higher education institutions for supporting students' success. However, the complexity of academic advising program structures, the difficulties in identifying appropriate outcome measures, and the lack of inclusion of multiple stakeholders' perspectives continue to challenge scholars to…

Comparison studies conducted to determine which instructional interventions are most efficient for teaching discrete behaviors to individuals with disabilities are potentially valuable, although some threats to internal validity may be more likely in these studies. Studies included in this review typically met common internal validity standards,…

While there has been a lot of debate over the impact of online and remote learning on mental health and well-being, there has been no systematic syntheses or reviews of the research on this particular issue. In this paper, we review the research on the relationship between mental health/well-being and online or remote learning. Our review shows…

Over the past 15 years, we have seen an increase in the use of cluster randomized trials (CRTs) to test the efficacy of educational interventions. These studies are often designed with the goal of determining whether a program works, or answering the what works question. Recently, the goals of these studies expanded to include for whom and under…

Mixed methodology holds considerable promise for the field of literacy research, yet it continues to be underrepresented in published research. The purpose of this study was to identify potential problems in conducting and publishing reports of mixed methods research in literacy. Predicated on a view of research as principled argument, we…

Given the importance of social integration and participation in inclusive settings for young children with autism spectrum disorder (ASD), the purpose of this systematic review was to examine instructional outcomes and participant, teacher, group, and instructional characteristics that may be pertinent to successful group instruction for young…

Inappropriate behavior on school buses is a safety issue that concerns students, parents, and educators. There is potential for traffic-related injury, and the limited adult supervision on school buses often facilitates bullying and other infractions. This review identified peer-reviewed articles and dissertations evaluating behavioral…
