This paper presents a design-based research project undertaken to test and implement an interest-based engineering challenges framework for pre-college students. This work is motivated by the need for innovative engineering education practices in pre-college settings, and making engineering more inclusive for people from diverse backgrounds. The…

Driven by our recent mapping of the human genome, genetics research is increasingly prominent and beginning to reintersect with education research. We describe previous intersections of these fields, focusing on the ways that they were harmful. We then discuss novel features of genetics research in the current era, with an emphasis on…

Research management is an emerging field of study and its development is significant to the advancement of research enterprise. Developing the science of research management requires investigating social mechanisms involved in research management. Yet, studies on social mechanisms of research management is lacking in the literature. To address…

As complex systems approaches to research gain a foothold in educational research, educational researchers may be faced with unique study design challenges. Studies that do not target appropriate levels of analysis or do not capture variable change over time at a fine enough granularity run the risk of missing complex, dynamic, and emergent…

Differentiated instruction is a teaching philosophy and practice that deals with responding appropriately to student heterogeneity. In order to gain deep understanding of this complex concept, research methodology is challenged to use appropriate data collection and data analysis. The aim of this paper is to reflect on how system theory may be…

Ainsworth et al.'s paper "Sources of Bias in Outcome Assessment in Randomised Controlled Trials: A Case Study" examines alternative accounts for a large difference in effect size between 2 outcomes in the same intervention evaluation. It argues that the probable explanation relates to masking: Only one outcome measure was administered by…

Single-case research methods provide the basis for evaluating effective instructional approaches in special education. The purpose of this article is to provide special educators an overview of single-case research methods, with an emphasis on how these designs are used to establish whether an instructional practice relates to improved learner…

This article shows how statistical matching methods can be used to select "most similar" cases for qualitative analysis. I first offer a methodological justification for research designs based on selecting most similar cases. I then discuss the applicability of existing matching methods to the task of selecting most similar cases and…

This article draws upon the experiences of four recent efforts to synthesize the findings of quantitative studies in science education research. After establishing the need for research syntheses in advancing generalizable knowledge and causal effects research in our field, we identify a set themes that emerged in the process of conducting these…

In June 2014, a paper reporting the results of a study into 'emotional contagion' on Facebook was published. This research has already attracted a great deal of criticism for problems surrounding informed consent. While most of this criticism is justified, other relevant consent issues have gone unremarked, and the study has several other ethical…

In this article we describe the process followed in the creation of the "Hopscotch Model," a tool to help novice researchers thoroughly design qualitative research studies while learning the philosophical underpinnings of this particular form of research. The model helps to incorporate the theoretical background behind any qualitative…

Recent studies show cluster randomized trials may be well powered to detect mediation or indirect effects in multilevel settings. However, literature has rarely provided guidance on designing cluster-randomized trials aim to assess indirect effects. In this study, we developed closed-form expression to estimate the variance of and the statistical…

This study examines the tendencies in Turkey-based scientific articles related to distance education during the COVID-19 pandemic. In this qualitative study, content analysis and categorical analysis were used. The population of the study is comprised of Turkey-based academic studies on distance education while the sample consists of 125…

To plan cluster-randomized trials with sufficient statistical power to detect intervention effects on student achievement, researchers need multilevel design parameters, including measures of between-classroom and between-school differences and the amounts of variance explained by covariates at the student, classroom, and school level. Previous…

Many students in the sciences are interested in exploring research opportunities; however, the one-on-one faculty mentorship model often lacks the ability to supervise large numbers of students. An alternative mechanism for exposing undergraduate students to the research process is participation in a Course-based Undergraduate Research Experience…
