COVID-19 led to an increase in online higher education courses. With this increase in demand, there needs to be online support to foster students' academic success. Online academic student support is often provided to students to assist them in developing the skills and knowledge to successfully complete their courses. However, it remains unclear…

Grouped and right-censored (GRC) counts have been used in a wide range of attitudinal and behavioural surveys yet they cannot be readily analyzed or assessed by conventional statistical models. This study develops a unified regression framework for the design and optimality of GRC counts in surveys. To process infinitely many grouping schemes for…

Motivation to read is a central consideration for teachers and researchers because it is strongly associated with reading performance and is generally accepted as a positive state. The study of reading motivation is plagued by inconsistent terminology and measurement, which impedes a comprehensive knowledge base for teachers and researchers. One…

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…

Background: The generalizability of a study's results continues to be at the forefront of concerns in evaluation research in education (Tipton & Olsen, 2018). Over the past decade, statisticians have developed methods, mainly based on propensity scores, to improve generalizations in the absence of random sampling (Stuart et al., 2011; Tipton,…

Visual analysis and nonoverlap-based effect sizes are predominantly used in analyzing single case experimental designs (SCEDs). Although they are popular analytical methods for SCEDs, they have certain limitations. In this study, a new effect size calculation model for SCEDs, named performance criteria-based effect size (PCES), is proposed…

A precisely formulated research question is becoming increasingly important within the humanities. This applies not only to research funding applications, but also to articles, papers, and student theses. This article presents a tool allowing students to develop research questions on their own, which is open enough to allow for a wide variety of…

Several branches of the potential outcome causal inference literature have discussed the merits of blocking versus complete randomization. Some have concluded it can never hurt the precision of estimates, and some have concluded it can hurt. In this article, we reconcile these apparently conflicting views, give a more thorough discussion of what…

In single-case research designs (SCDs) to determine a functional relation a time-series graph is constructed. Preliminary evidence suggest the approach used to scale the vertical axis and the data points per x- to y-axis ratio (DPPXYR) impact visual analysts' decisions. We conducted a systematic review to evaluate time-series graphs published in…

This article serves as an overview of qualitative inquiry for leadership development practitioner-scholars both new and experienced. It begins with a discussion of the need for the qualitative inquiry to create knowledge about leadership development. Then, it overviews design components and includes examples of both research and assessment. We…

Random encouragement designs evaluate treatments that aim to increase participation in a program or activity. These randomized controlled trials (RCTs) can also assess the mediated effects of participation itself on longer term outcomes using a complier average causal effect (CACE) estimation framework. This article considers power analysis…

Outdoor programs have shown holistic health benefits for participants, with recent evidence indicating that these benefits can extend long after the conclusion of the program. The methods employed in retrospective studies exploring these outcomes are diverse, leading to many different approaches. Furthermore, only a few studies reference a…

We conducted a scoping review on the consecutive controlled case series (CCCS) methodology (Hagopian, 2020). The CCCS is an approach to studying functional relations across a series of consecutive cases that share common features. We identified and reviewed 76 studies that used CCCS methodology. Most of these (a) were retrospective CCCS studies…

Mathematics teacher leadership is promising, yet complex work, and research interest in this form of leadership is on the rise. This systematic review takes stock of the current research landscape on mathematics teacher leadership, specifically mathematics specialists as teacher leaders (MSTLs), and approaches the questions: (1) What are the…

This review addresses the current knowledge on inclusive education suggesting that many studies focus on predetermined groups of disadvantaged learners . This review aims 1) to map the research on inclusive education for all (IEFA) and 2) to assess the consistency of studies in their approach to inclusive education (IE), research methodology and…
