Data for individual trials included in systematic reviews may be available in multiple sources. For example, a single trial might be reported in 2 journal articles and 3 conference abstracts. Because of differences across sources, source selection can influence the results of systematic reviews. We used our experience in the Multiple Data Sources…

In recent years, there has been increasing interest in the combination of two methods on the basis of set theory. In our introduction and this special issue, we focus on two variants of cross-case set-theoretic methods--"qualitative comparative analysis" (QCA) and typological theory (TT)--and their combination with process tracing (PT).…

This paper was prompted by the question, what do we mean by conducting "ethnography"? Is it in fact "case study" drawing on ethnographic techniques? My contention is that in many cases, researchers are not actually conducting ethnography as understood within a traditional sense but rather are engaging in case study, drawing on…

This article examines the main ideas presented in Newell's groundbreaking article, published in "Issues in Integrative Studies" in 2001, "A Theory of Interdisciplinary Studies": that complexity is a precondition for interdisciplinary research, that interdisciplinary research utilizes disciplinary perspectives, and that…

STEM (Science, Technology, Engineering, Mathematics) Education; Is an educational approach that many countries in the world have included in their curricula that allow learners to view the knowledge they learn in science, technology, engineering and mathematics courses, aiming at transforming theoretical knowledge into practice, product and…

Free listing exercises are common and informative ways to explore shared bodies of knowledge and practice, and they can probe widely experienced phenomena in daily life. However, even with a representative sample, this method can suffer under common conditions in anthropological fieldwork: Respondents forget to list items, they fail to provide…

Literature reviews, and more particularly systematic reviews, are increasingly being produced and published. The past 40 years have been marked by considerable development of methodologies and methods in literature reviews. This paper aims to provide a brief historical overview of systematic reviews which will help to have a better understanding…

The objective was to determine the methodological quality and identify the characteristics of the psychology theses approved in the 2014-2017 period of a private university in Peru. The study is descriptive and bibliometric, in which the study population was 161 theses approved in the period 2014 - 2017, out of which 149 extensive files available…

The purpose of this paper is to clarify the philosophical and methodological variations of phenomenological research methods and their role in the field of educational communication and technology (ECT). Phenomenology is a qualitative research methodology concerned with investigating phenomena as they manifest through lived-experiences. The unit…

The field of instructional design and technology (IDT) aims to understand the interactions occurring among people and learning resources during educational experiences to inform design. This article illustrates the utility of mobile eye-tracking for research with children as a tool for IDT researchers and practitioners. Mobile eye-tracking can…

Q methodology is an underutilized research methodology in the fields of education, instructional design and instructional technology, yet is well suited to research on perceptions of learning, efficacy of design, technology adoption and other issues within those fields. One reason for its lack of widespread use is the somewhat cumbersome nature of…

This paper explores how to apply the principles of accommodations and universal design (UD) in research methods involved in quantitative research (e.g. questionnaires). In particular, we focus on how to make research more accessible for individuals with Learning Disabilities (LD), while also providing suggestions for potential participants of…

The video game industry is a global multibillion dollar industry with millions of players. The process of developing video games is essential for the continued growth of the industry, and developers need to employ effective strategies that will help them to create successful games. The purpose of this explorative qualitative single case study was…

Like numerous others before us, we argue that the educational research community would be well served by a mutually created cyberinfrastructure that encourages and supports engagement by multiple design-based researchers in working toward answers to important theory-driven research questions, moving our field toward a "bigger science"…

In this dissertation, I study those research practices and values which limit trans-disciplinarity among academics of science teaching & learning. I consider trans-disciplinarity an ethically imbued practice that enables thinking about the productivity of our research practices and makes possible flows of connectivity in the generation of our…
