Estimating the effects of randomized experiments and, by extension, their mediating mechanisms, is often complicated by treatment noncompliance. Two estimation methods for causal mediation in the presence of noncompliance have recently been proposed, the instrumental variable method (IV-mediate) and maximum likelihood method (ML-mediate). However,…

Research skills, especially in experimental design, are essential for success in bioscience doctoral training. While there is a growing body of literature on the development of research skills among science, technology, engineering, and mathematics doctoral students, very little is specific to biosciences. We seek to address this gap by…

In this article, the authors describe critical issues related to the pursuit of rigorous and innovative research in the fields of mathematics and science education. The paper is framed to help researchers consider aspects of both their research project and their research proposal. The authors describe features of high-quality and fundable research…

This paper describes aspirations and contributions that grew out of a developmental cycle of design-based research (DBR) implementation conducted over a three-year project. DBR engineers new learning environments and improves learning in context whilst communicating usable knowledge for learning and teaching in complex settings. This project…

Group assignments are a near-universal feature of classrooms around the world. They are broadly viewed as more effective than passive forms of learning and are assumed to position students for success in fields that demand high levels of interpersonal communication, like public affairs. But does research support that view? This article examines…

Longitudinal studies are commonly used in the social and behavioral sciences to answer a wide variety of research questions. Longitudinal researchers often collect data anonymously from participants when studying sensitive topics to ensure that accurate information is provided. One difficulty gathering longitudinal anonymous data is that of…

The COVID-19 outbreak emphasizes the need for alternative methods for data gathering and collaboration among researchers in a virtual research environment. One experimental design that is well suited in a social distancing research context is the single-case experimental design (SCD). SCDs can handle disruptions as: (a) they do not require large…

In this study, we re-analyze recent empirical research on replication from a meta-analytic perspective. We argue that there are different ways to define "replication failure," and that analyses can focus on exploring variation among replication studies or assess whether their results contradict the findings of the original study. We…

Given the importance of social integration and participation in inclusive settings for young children with autism spectrum disorder (ASD), the purpose of this systematic review was to examine instructional outcomes and participant, teacher, group, and instructional characteristics that may be pertinent to successful group instruction for young…

Mixed methodology holds considerable promise for the field of literacy research, yet it continues to be underrepresented in published research. The purpose of this study was to identify potential problems in conducting and publishing reports of mixed methods research in literacy. Predicated on a view of research as principled argument, we…

Research on teaching effectiveness, especially those concerning teaching approaches and instructional strategies, rarely shows conclusively the effectiveness of an intervention. Then, these (quasi-) experimental studies on teaching effectiveness often involve distal measures of teaching components. In this article, the focus is on another likely…

"Educational Research: Planning, Conducting, and Evaluating Quantitative and Qualitative Research" offers a truly balanced, inclusive, and integrated overview of the processes involved in educational research. This text first examines the general steps in the research process and then details the procedures for conducting specific types…

This article examines the development, impact and integration of interdisciplinary approaches in British Higher Education Institutions. It evaluates how the concept of interdisciplinarity has become popularised over time and embraced by disciplines such as archaeology. It then explores the extent to which interdisciplinary approaches have impacted…

The analysis of exemplars of different quality is a potentially powerful tool in enabling students to understand assessment expectations and appreciate academic standards. Through a systematic review methodology, this paper synthesises exemplar-based research designs, exemplar implementation and the educational effects of exemplars. The review of…

This case study shares the lessons learned from the data collection phase of my research project, specifically the use of online interviews with stimulus material. My research explores secondary school teachers' perceptions of and experiences with moral education in the United Kingdom and uses current government policies regarding the moral…
