Meta-analyses play an instrumental role in informing second language (L2) theory and practice. However, current (i.e., classic) approaches to meta-analysis are limited in their ability to do so because they often fail to capture the complexity inherent in primary studies' research designs. As we argue in this article, when complex L2 studies are…

In educational research, the complexity of interventions and the diversity of contexts challenge the adequacy of existing reporting standards, primarily tailored for health interventions and randomised controlled trials. Recognising the critical need for appropriate tools to support education research, we developed two checklists: the CheckList Of…

A recent issue of the Australian Journal of Language and Literacy included an article reporting on a systematic narrative review of the research literature that indicated that there was insufficient evidence to conclude whether genre theory and systemic functional linguistics either 'worked' or 'did not work'. The criteria used to evaluate these…

Special education policy and scholarship have increasingly emphasized the use of research that encompasses interdependent methodological approaches designed to address specific questions. Consequently, the knowledge available to practitioners, policymakers, and other consumers is a function of the research designs featured in the literature. This…

It is difficult for consumers to access the evidence base for prevention programs to determine which models or practices have the strongest empirical support for improving youth social, emotional, and behavioral (SEB) outcomes within their specific service contexts. Researchers can address this evidence-to-practice gap through innovations in…

Scholarly efforts to identify core design features for effective teacher professional development have grown rapidly in the last 25 years. Many concise lists of design principles have emerged, most of which converge on a consensus of 5-7 presumably 'effective' features (e.g. collaborative tasks, active learning, focus on content). The…

The Campbellian validity typology has been used as a foundation for outcome evaluation and for developing evidence-based interventions for decades. As such, randomized control trials were preferred for outcome evaluation. However, some evaluators disagree with the validity typology's argument that randomized controlled trials as the best design…

Science educators report that students struggle with understanding, using, and evaluating the evidence underpinning scientific knowledge. However, there are not many studies focused on helping instructors address those difficulties. Here, we report on a laboratory instructor's scaffolding of students' evidentiary reasoning with and about evidence…

Computation is foundational to learning many mathematics concepts, as well as a functional skill in everyday life. Yet students with autism spectrum disorder (ASD) often have challenges in learning computation skills. The current study aimed to provide quantitative and descriptive analyses of single-case experimental studies on computation…

Higher education professionals often are tasked with providing evidence to stakeholders that programs, services, and practices implemented on their campuses contribute to student success. Furthermore, in the absence of a solid base of evidence related to effective practices, higher education researchers and practitioners are left questioning what…

During the COVID-19 pandemic, the race to find an effective vaccine or treatment saw an 'extraordinary number' of clinical trials being conducted. While there were some key success stories, not all trials produced results that informed patient care. There was a significant amount of waste in clinical research during the pandemic which is said to…

By illuminating why and how interventions work in real world settings, Implementation Research (IR) is a powerful tool for increasing the likelihood that evidence-based interventions, programmes and policies are successfully implemented. The insights that IR generates help bridge the 'know-do gap'--the gap between what we know works and what…

This innovative guide is now in a revised and expanded second edition with an even stronger applied focus. It helps educators harness the potential of single-case design (SCD) as a critical element of data-based decision making in a multi-tiered system of support (MTSS). The authors present simple and complex SCDs and demonstrate their use to…

Background: The utility of single-subject designs as a practical methodology for rehabilitation professionals working in the field and one that allows researchers the flexibility to identify or change treatments in the event their participant or client is not responding has been established for nearly a century (Dixon, 2002). However, a content…
