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…

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…

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…

This essay defines and critiques "methodocentrism", the belief that predetermined research methods are the determining factor in the validity and importance of educational research. By examining research in science studies and posthumanism, the authors explain how this methodocentrism disenables research from taking account of problems…

Single-case researchers frequently adopt a form of response-guided experimentation where decisions about the design of the study are made based on an ongoing visual analysis. For example, multiple-baseline researchers may delay the start of intervention until data document a stable baseline pattern so that baseline trends can be reliably extended,…

David Berliner argued in 2002 that educational research is the hardest science of all. His arguments addressed the complexity that context plays in educational settings and the difficulties of applying research designs that were largely developed and refined in the natural sciences arena to fields of human behavior. In this article, it is argued…

As the prevalence of conflict and fragility continue to rise around the world, research is increasingly heralded as a solution. However, current ethical guidelines for working in areas suffering from institutional and social fragility, insecurity or violent conflict have been heavily critiqued as highly abstract; focussed only on data collection;…

This research aims to make a methodological contribution to the mixed methods literature by investigating the value-added of empirical studies that are explicitly framed with the purpose of interrogating divergent findings. Case studies introduce the role philosophical paradigms can play in reconciliation process and reveal the potential to…

The scientific rigor of education research has improved dramatically since the year 2000. Much of the credit for this improvement is deserved by Institute of Education Sciences (IES) policies that helped create a demand for rigorous research; increased human capital capacity to carry out such work; provided funding for the work itself; and…

Background: The use of randomised controlled trials (RCTs) in education has increased significantly over the last 15 years. However, their use has also been subject to sustained and rather trenchant criticism from significant sections of the education research community. Key criticisms have included the claims that: it is not possible to undertake…

Researchers sometimes conduct a study and find that the predicted relation between variables did not exist or that the intervention did not have a positive impact on student outcomes; these are referred to as null findings because they fail to disconfirm the null hypothesis. Rather than consider such studies as failures and disregard the null…

Single-subject designs provide the special education field with an alternative to group designs. The purpose of this paper is to introduce the topic of single-subject designs by providing an overview of the relevant literature and a discussion of the major issues and applications of these designs in the field of special education. This paper is…

Treatment effect estimates from a "regression discontinuity design" (RDD) have high internal validity. However, the arguments that support the design apply to a subpopulation that is narrower and usually different from the population of substantive interest in evaluation research. The disconnect between RDD population and the…

This paper focuses on self-assessment studies in the higher education field. In the assessment for learning perspective, self-assessment is related to reflection, metacognition, and self-regulation: all these aspects are considered as fundamental prerequisites for students' future professional development. Despite the recognition of…
