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 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…

Interventions often require multiple decisions to improve outcomes for every student. Whether the decision to implement a practice, tailor an existing protocol, or change approaches, these decisions should be based on individual variables and outcomes via a sequence of treatment. To develop adaptive interventions that have sufficient evidence to…

Validation is a critical element of analysis which increases the credibility, rigor, and trustworthiness of research. Interpretive phenomenology traditionally has employed member checking as the validation tool to support the themes cultivated from data. However, the literature has challenged member checking as being insufficient or inaccurate in…

Experimental studies are often employed to test the effectiveness of teaching innovations such as new pedagogy, curriculum, or learning resources. This article offers guidance on good practice in developing research designs, and in drawing conclusions from published reports. Random control trials potentially support the use of statistical…

Background: Africa is increasingly becoming an important region for health research, mainly due to its heavy burden of disease, socioeconomic challenges, and inadequate health facilities. Regulatory capacities, in terms of ethical review processes, are also generally weak. The ethical assessment of social and behavioral research is relatively…

Experimental design is a desirable outcome of laboratory education. Incorporating inquiry into the laboratory curriculum is attractive, but there are acknowledged concerns from practical, theoretical, and epistemological perspectives, and these are accentuated in upper-division courses. In this work, we draw on the extensive literature relating to…

Weisman and Montgomery completed an overview of reviews to evaluate the status of research concerning functional family therapy (FFT). Despite reporting modest effects on delinquency, substance use, and secondary outcomes, the authors conclude that the research base supporting FFT is tenuous and that it "may not be advisable to continue…

Correspondence testing to research discrimination in the marketplace has become common and the use of internet applications has allowed researchers to send greater numbers of applications. While questions of research ethics always arise when planning a correspondence test, the issue receives relatively little attention in published correspondence…

Authors performed a content analysis of school counseling-related intervention research in 21 journals affiliated with the American Counseling Association and the American School Counselor Association across the 10-year span of 2006-2016. Results indicated that minimal school counseling intervention research articles were published (N = 53) in…

Using an RD design provides statistically robust estimates while allowing researchers a different causal estimation tool to be used in educational environments where an RCT may not be feasible. Results from External Evaluation of the i3 Scale-Up of Reading Recovery show that impact estimates were remarkably similar between a randomized control…

For decades, the notion of teachers engaging in research has been discussed and carried out under the heuristics and methodologies of action research (Manfra, 2019; Pine, 2009). A typical action research project might involve an individual teacher studying the effectiveness of a specific instructional strategy like having students preview content…
