Understanding complex (social) phenomena benefits from combining different tools, perspectives, expertise, and experiences. Research designs that combine approaches are gaining in popularity. Carrying out research in interdisciplinary teams, however, is a challenging, high-investment activity. Unawareness of and reflecting on conflicting ways of…

Once research questions are posed, researchers must answer many a priori questions regarding research design before analysis can be performed and any conclusions can be made, including sample selection criteria, data collection method, model specification, analysis and estimation technique. The choices made by researchers along this forking path…

The main objective of this methodological article is to discuss the contribution of response times as a tool in education research. The use of response times in research is largely a legacy of the work carried out in cognitive psychology, which has made it possible to describe the cognitive processes involved in information processing. In…

Managing and analysing large qualitative datasets pose a particular challenge for researchers seeking a consistent and rigorous approach to qualitative data analysis. This paper describes and demonstrates the development and adoption of a matrix tool to guide the qualitative data analysis of a large sample (N = 122) of interview data. The paper…

Identifying and fostering gifted students is crucial in educational science and psychology. Giftedness diagnostics must be based on profound domain-specific concepts and acknowledge the variety of talents to enable a successful individual education. Growing challenges like digitalization, decarbonization, demographic changes, and pandemics…

This paper describes a content analysis used to examine educational doctoral degrees (EdD) dissertations in a U.S. university. The purpose of the study was to get a better understanding of the validation techniques utilized in dissertations published by EdD students. Forty-nine dissertations were selected and examined for research methodologies,…

Introduction: Designing and conducting an intervention study is an arduous task for students that requires strong teaching and mentoring practices from psychology instructors. Statement of the Problem: Most research methods textbooks simply describe how an intervention is incorporated into a research study design (Johnson & Christensen, 2016),…

The thesis by publication (TBP)--a collection of standalone articles aimed at publication and accompanied by an explanatory narrative--has grown in popularity over the last two decades. Although research on the TBP is beginning to emerge, it is thus far fragmented. We carried out a scoping review of the literature on the TBP for the years…

The purpose of this study was to investigate the conceptualisation and contextualisation of mixed-methods research within the research methodology paradigm to ascertain the categorisation of mixed methods as a type of research, research design or research approach. The methodology adopted for this paper is qualitative in nature and involves the…

The purpose of this study was to investigate the effectiveness of four different models (bifactor, CTC(M-1), CTCU and unidimensional) as to optimal model selection when the wording effect associated with negatively worded items was present. A Monte Carlo simulation study was conducted to compare model-data fit and accuracy in parameter estimates…

In order to produce the most reliable syntheses of the effectiveness of educational interventions, systematic reviews need to adhere to rigorous methodological standards. This meta-review investigated risk of bias occurring while conducting a systematic review and the presence of open science practices like data sharing and reproducibility of the…

This article ponders the question: "How might EdD research methods courses be reimagined to position Black Feminist Theory as a comparable theoretical framework to guide epistemological stance development and scholar-practitioner inquiry?" By introducing Black Feminist Theory as a viable theoretical framework, this article posits its…

David Clarke's research has shifted the focus of classroom research in mathematics education from study of cultural patterns to study of patterns of participation and the learning that can result in highly complex social environments. His Complementary Accounts Methodology which informed the Learner's Perspective Study design included multi-source…

Criteria are briefly proposed for final conclusions, research problems, and research hypotheses in quantitative research. Moreover, based on a proposed definition of applied and basic/general research, it is argued that (1) in applied quantitative research, while research problems are necessary, research hypotheses are unjustified, and that (2) in…

Studies using co-design methods require the meaningful involvement of stakeholders in creating new knowledge and harnessing, mobilising, and transferring existing knowledge to support comprehensive and long-term solutions. In the health sector, co-design methodology is seen as a way of supporting and engaging local communities in critical…
