Cluster randomized trials (CRTs) are commonly used to evaluate educational interventions, particularly their effectiveness. Recently there has been greater emphasis on using these trials to explore cost-effectiveness. However, methods for establishing the power of cluster randomized cost-effectiveness trials (CRCETs) are limited. This study…

Recently, inspirational articles on research methodology have been written on the development of the mixed-methods approach. This area of study concerns methodological trends in the construction of research designs. One may ask, whether it is possible to construct a notional piece of investigation, potentially highlighting a research design that…

Changing criterion designs (CCD) are single-case experimental designs that entail a step-by-step approximation of the final level desired for a target behavior. Following a recent review on the desirable methodological features of CCDs, the current text focuses on an analytical challenge: the definition of an objective rule for assessing the…

Computational thinking (CT) has received growing interest as a research subject in the last decade, with research contributions attempting to capitalize on the benefits that CT may provide. This study included a systematic analysis aimed at revealing current trends in the CT subject, identifying educational interventions, and emerging assessment…

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…

This paper reports the findings of the second year of a four-year empirical research project. Its aim is to modify 'step-by-step' instructions for practical activities in a way that may enable the development of experimental design skills among junior high school learners. Each school year pupils spend six lessons doing practical activities using…

In this article, we explore ethical issues of Deaf people's engagement in research. To focus on the perspectives of Deaf people, we investigated existing qualitative and mixed methods research within a qualitative evidence synthesis. Our synthesis is based on a systematic database search (Scopus, PubMed) and reference check of included papers…

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…

Based on year-long fieldwork on activist-educators' work in South Korea, I reflect on how my research complicates the ontological shift in institutional ethnography: that is, the shift that emphasizes how ruling relations are coordinated through the very actions of people. I discuss two facets of reflective pauses. First, I discuss how the ruling…

Single-case research methods provide a basis for demonstrating that an intervention produces a reliable change in a targeted outcome for individual cases. To supplement visual analysis of data in single-case studies, researchers frequently report statistics--often referred to as effect sizes--to summarize study findings. The recent proliferation…

Cluster randomized trials are frequently used in educational research for methodological reasons. This study aims to improve the efficiency of cluster randomized trials on computer/information literacy and computational thinking. The study employs a two-level hierarchical linear model to estimate: (1) intraclass correlation coefficients; (2) the…

The following article comprises an autoethnographic discussion of researcher identity in school-based educational research. The research centred on a professional learning programme in which arts/education practitioners delivered workshops for teachers that used creative, arts practice with a focus on mindful techniques to support teachers'…

The purpose of this research is to reveal the research trends of postgraduate theses published in the field of digital literacy published in Turkey between 2015 and 2020. In this context, a total of 34 postgraduate theses on digital literacy published between 2015 and 2020 in the database of YÖK (Higher Education Institution) National Thesis…

All cognitive diagnostic models that evaluate educational test data require a Q-matrix that combines every item in a test with the required cognitive skills for each item to be answered correctly. Generally, the Q-matrix is constructed by education experts' judgment, leading to some uncertainty in its elements. Various statistical methods are…

Mixed-methods research can uniquely inform special education practice by combining qualitative and quantitative research approaches. However, its distinct features can also make mixed-methods research difficult to understand and apply. In this article, we provide an introduction to mixed-methods research purposes, designs, and quality…
