When reviewing single-case design research, the What Works Clearinghouse (WWC) first reviews each single-case design experiment within a study (or research article) to determine whether it meets standards. For each experiment that meets standards, the WWC then uses visual analysis to characterize the evidence of a causal relationship. The WWC…

The What Works Clearinghouse (WWC) Standards Briefs explain the rules the WWC uses to evaluate the quality of studies for practitioners, researchers, and policymakers. An aspect of a study is considered a confounding factor if it is not possible to tell whether the difference in outcomes is due to the intervention, the confounding factor, or both.…

The Report of the National Literacy Panel on Language-Minority Children and Youth was designed to be a definitive review of research on the literacy development of language-minoritized students. We adopt conceptual methods from rhizomatic mapping to replicate the report's literature searches and critically examine studies eliminated based on the…

What aspects of writing are doctoral students metacognitive about when they write research articles for publication? Contributing to the recent conversation about metacognition in genre pedagogy, this study adopts a qualitative approach to illustrate what students have in common, across disciplines and levels of expertise, and the dynamic…

Difficulty with communication and social functioning are two outstanding core symptoms of autism spectrum disorder, and physical activity has long been suggested to improve autism spectrum disorder symptoms. In this meta-analysis of controlled trials, we examined the effects of physical activity interventions compared to controls on communication…

When previous research is cited incorrectly, misinformation can infiltrate scientific discourse and undermine scholarly knowledge. One of the more damaging citation issues involves incorrectly citing article content (called quotation errors); therefore, investigating quotation accuracy is an important research endeavor. One field where quotation…

We present a systematic review of the literature on the use of multiuser virtual environments (MUVE) on the development of pragmatic competence in second language (L2) learners. Specifically, we reviewed studies examining the potential of L2 pragmatic development through synthetic immersive virtual environment (SIE) and massively multiplayer…

Literacy research has investigated disciplinary literacy for over a decade. The focus on disciplines as cultures of distinct literacy practice has been integrated into national standards and classroom implementation. Yet, research exploring the professional development in-service teachers receive specific to delivering disciplinary literacy…

Purpose: We report the results of a systematic review and meta-analysis investigating the relationship between perceptual anchoring and dyslexia. Our goal was to assess the direction and degree of the effect between perceptual anchoring and reading ability in typical and atypical (i.e., dyslexic) readers. Method: We performed a literature search…

In the research subfield of social media memory studies (Birkner & Donk, 2020), digital memory of relevant historical events has its own scholarship and avenues of publication (e.g., Garde-Hansen et al., 2009; Hoskins, 2011). As for the specific area of Holocaust studies, with the passing of the generation that witnessed and experienced the…

In 2018, to help undergraduate medical students strengthen their self-learning and scientific research skills, we introduced an instructional model that combined literature-based learning with experimental design. We tested this model on the molecular biology class at Tongji University. In the first step of the model, a topic is chosen, and…

In recent years, the need for English as a foreign language (EFL) education in schools has become a priority worldwide. The aim of our paper is to investigate which countries currently focus on researching motivation to learn EFL and what potential reasons are behind the focus. We performed a topic search of the keywords "EFL" and…

This study focuses on the grammatical devices--and semantic distinctions thereof--that are employed by academic writers of English to express stance in research article abstracts in the areas of applied…

"Shifting Sands: Unsound Science and Unsafe Regulation" examines how irreproducible science affects select areas of government policy and regulation governed by different federal agencies. This first report on "PM[subscript 2.5] Regulation" focuses on irreproducible research in the field of environmental epidemiology, which…

Background/Context: Literacy skills are critical to understanding information presented in written or oral formats and communicating effectively with others.
