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…

This research was carried out to analyse the efficiency on University International Research Collaboration (IRC) and examines disciplines that are popular areas for collaboration. Based on data for the years 2015-2021, an empirical study was conducted to determine how to implement Data Envelopment Analysis (DEA) in 56 research partner countries in…

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…

In this Methods Showcase Article, we outline a workflow for running behavioral experiments online, with a focus on experiments that rely on presentation of complex stimuli and measurement of reaction times, which includes many psycholinguistic experiments. The workflow that we describe here relies on three tools: OpenSesame/OSWeb (open source)…

Experimental studies of educational interventions are rarely based on representative samples of the target population. This simulation study tests two formal sampling strategies for selecting districts and schools from within strata when they may not agree to participate if selected: (1) balanced selection of the most typical district or school…

Background/Context: Methodological background: Meta-analysis typically depends on the assumption that true effects follow the normal distribution. While assuming normality of effect "estimates" is often supported by a central limit theorem, normality for the distribution of interventions' "true" effects is a computational…

The implementation of context-based chemistry programs has been started before 40 years ago since 1980s in an attempt to make the learning of chemistry more meaningful for students. Consequent to its lengthy, there has been a steady increase in the number of interventional context-based (ICB) approach chemistry studies investigating the effect of…

Qualitative researchers often turn to focus groups as an efficient and effective way to gather data in a collective context. A common critique is that they play into power dynamics present at the site, privileging dominant, high status, and more vocal participants. Traditional focus group structures also rely on participants to trust the…

In this paper, we critically examine the way in which scholars have traditionally defined and problematized attrition. Through a series of examples of large-scale intervention impact studies, we share insights about the sources and consequences of attrition that expand our notion of how and why attrition occurs. We also discuss potential steps for…

Yinyang philosophy encompasses an essential understanding of the mechanism and laws of nature, cosmos, and human society in Chinese culture, and reaches to many other parts of Asia and around the world. The purpose of this article is to explore how yinyang philosophy can serve as a philosophical underpinning of mixed methods research (MMR). In…

The purpose of this descriptive study was to investigate course-based undergraduate research experience (CURE) outcomes of community college students by looking at students' sense of project ownership, science self-efficacy, and science identity using an end of course survey. A total of 54 students, 41 females and 13 males, completed the survey.…
