Meta-analyses are often used to estimate the relative average values of a quantitative outcome in two groups (eg, control and experimental groups). However, they may also examine the relative variability (variance) of those groups. For such comparisons, two relatively new effect size statistics, the log-transformed "variability ratio"…

The methodology of single-case experimental designs (SCED) has been expanding its efforts toward rigorous design tactics to address a variety of research questions related to intervention effectiveness. Effect size indicators appropriate to quantify the magnitude and the direction of interventions have been recommended and intensively studied for…

Single-Case Experimental Designs (SCEDs) have lately been recognized as a valuable alternative tolarge group studies. SCEDs form a great tool for the evaluation of treatment effectiveness in heterogeneous and low-incidence conditions, which are common in the field of communication disorders. Mediation analysis is indispensable in treatment…

The What Works Clearinghouse (WWC) systematic review process is the basis of many of its products, enabling the WWC to use consistent, objective, and transparent standards and procedures in its reviews, while also ensuring comprehensive coverage of the relevant literature. The WWC systematic review process consists of five steps: (1) Developing…

Descriptive analyses of socially important or theoretically interesting phenomena and trends are a vital component of research in the behavioral, social, economic, and health sciences. Such analyses yield reliable results when using representative individual participant data (IPD) from studies with complex survey designs, including educational…

Course-based undergraduate research experiences (CUREs) increase student engagement in scientific practices and empower students to generate novel findings. Previous studies have demonstrated that CUREs are more effective at enhancing students' motivations, attitudes, science identity development, and acquisition of science process skills than…

As part of our ethical responsibilities as scholar-practitioners and community members living as uninvited guests on Indigenous territories, we engaged in a collaborative inquiry to explore ways in which Indigenous pedagogies and worldviews extend understandings of self within self-study research. Over several years, we engaged in reflective…

There is an increasing interest in the integration of computational thinking (CT) in the K-12 curriculum. By integrating CT into other disciplines, the aim is to equip students with essential skills to navigate domain-specific challenges. This study conducts a systematic review of 108 peer-reviewed scientific papers to analyze in which K-12…

This article discusses the development of an interactive online textbook for undergraduate teaching, in response to moving teaching online due to COVID-19. The development took place initially for a university with less than 5% of students studying online in 2019. The online textbook was incorporated into a large, diverse, multidisciplinary and…

Despite receiving increasing attention from mathematics education scholars, there has not yet been any overall understanding of the current state of realistic mathematics education (RME). To address this gap, this study aims to provide a review of 288 studies on realistic mathematics education from the Scopus database between 1972 and 2019. Using…

Including students with autism spectrum disorders (ASD) in general education is a common practice today. However, there are relatively few mathematics interventions for students with ASD in secondary education. There is also a lack of literature exploring mathematics interventions that reflect grade-level academic requirements and are adapted for…

This paper considers the adoption of computational techniques within research designs modeled after the extended case method. Echoing calls to augment the power of contemporary researchers through the adoption of computational text analysis methods, we offer a framework for thinking about how such techniques can be integrated into…

The 2019 National Survey of Early Care and Education (NSECE) is funded by the Office of Planning, Research, and Evaluation (OPRE) in the Administration for Children and Families. The project team is led by NORC at the University of Chicago. The 2019 NSECE is comprised of four integrated, nationally representative surveys which include: (1)…

Purpose: A Phase I pilot study was designed to collect preliminary evidence on the use of the Kaufman Speech to Language Protocol (K-SLP; Kaufman, 2014) to treat children with childhood apraxia of speech. We hypothesized that the K-SLP approach would result in more accurate speech production in targeted words, whereas untrained (control) words and…

When a theoretical framework (and its components) is not clearly linked to research methods, researchers risk designing flawed studies, wherein the stated research question is inconsistent with the research design. Explicitly identifying one's theoretical orientation can provide an orderly schematic for linking observations from separate…
