Conducting research with human subjects can be difficult because of limited sample sizes and small empirical effects. We demonstrate that this problem can yield patterns of results that are practically indistinguishable from flipping a coin to determine the direction of treatment effects. We use this idea of random conclusions to establish a…

Although the use of the cluster randomized trial (CRT) design to evaluate vaccines, public health interventions or health systems is increasing, the ethical issues posed by the design are not adequately addressed, especially in low- and middle-income country settings (LMICs). To help reveal ethical challenges, qualitative interviews were conducted…

Human Research Ethics Committee (HREC) reviewers often provide similar feedback across applications, which suggests that the problem lies in researcher awareness of key issues rather than novel, unsolvable challenges. If common problems can be addressed before lodgement by applicants referencing clear evidence-based supports (e.g., FAQs on common…

Background: The technological age of the twenty-first century has witnessed an upsurge in the demand for STEM education. Early childhood STEM learning and teaching has sparked attention among researchers. Purpose: This study aims to provide a holistic review of current STEM research in Early Childhood Education (ECE). Sample: We conducted a…

CADRE interviewed researchers to learn about their most effective strategies for recruiting and retaining participants for STEM education research. While there are no shortcuts to successful recruitment, a sustained commitment to understanding and addressing the needs of a district and its teachers is key to long-term success. In this new brief,…

In this research-to-resource article, I introduce possible uses of ChatGPT, an artificial intelligence chatbot developed by OpenAI, for music education research settings. I discuss the impacts of artificial intelligence on education environments and highlight uses of ChatGPT as a tool, including the role of ChatGPT in information gathering,…

This case study focuses on the use of qualitative interview methodology to understand the socioemotional states of undocumented students majoring in science, technology, engineering, and mathematics fields during the COVID-19 pandemic in the context of a recent research project. The term "socioemotional states" refers to the emotional…

The Q-matrix played a key role in implementations of diagnostic classification models (DCMs) or cognitive diagnostic models (CDMs) -- a family of psychometric models that are gaining attention in providing diagnostic information on students' mastery of cognitive attributes or skills. Using two Monte Carlo simulation studies, this dissertation…

This study provides a comprehensive review of the research design, themes, and theoretical development of internship literature in the context of business students. One hundred and ninety-two (192) articles retrieved from Scopus, Google Scholar, and the Web of Science databases and published from 1979 to 2022 were analysed. Information on…

Background: Education researchers typically estimate average program effects with regression; if they are interested in heterogeneous effects, they include an interaction in the model. Such models quantify and infer the influences of each covariate on the effect via interaction coefficients and their associated p-values or confidence intervals.…

Concerns have been raised about genomic studies of autism. Most recently, the Spectrum 10 K study was paused due to criticism from the autistic community. This situation raised important questions about how the autistic and autism communities perceive genomic research. The Personal Experiences of Autism and Perceptions of DNA-based-research study…

Purpose: We systematically reviewed the empirical literature that reports research in the specific context of teaching EFL to identify what is known about the efficacy of using flipped learning to teach EFL, the robustness of this evidence, and to explicate the strengths and weaknesses of the pedagogy in teaching EFL. Design/methodology/approach:…

Typically, parents or other legal guardians are asked for an active declaration that the participation of their child in scientific research is informed and voluntary. However, asking for active parental consent leads to lower quality studies and passive parental consent might be preferable. In this study, we used an online survey in which parents…

In fields (such as population health) where randomised trials are often lacking, systematic reviews (SRs) can harness diversity in study design, settings and populations to assess the evidence for a putative causal relationship. SRs may incorporate causal assessment approaches (CAAs), sometimes called 'causal reviews', but there is currently no…

Optimal sampling frameworks attempt to identify the most efficient sampling plans to achieve an adequate statistical power. Although such calculations are theoretical in nature, they are critical to the judicious and wise use of funding because they serve as important starting points that guide practical discussions around sampling tradeoffs and…
