The application of new methods and measures in domains with few methodological traditions of that kind often presents researchers with a challenge; they may have to take up the task of developing their understanding of the phenomenon while, at the same time, creating the practices for its study. For us, the method was eye tracking, and the topic,…

Despite being accepted as a key function in research management, research planning seems to be a neglected practice in some higher education institutions, particularly in economically disadvantaged countries such as Vietnam. This paper addresses a research gap in this area by examining (1) the practices of research planning at four leading…

We assess the potential for mixing social research methods, based upon a materialist and micropolitical analysis of the research-assemblage and of what individual research techniques and methods do in practice. Applying a DeleuzoGuattarian toolkit of assemblages, affects and capacities, we document what happens when research methods and techniques…

Evaluators of education interventions increasingly need to design studies to detect impacts much smaller than the 0.20 standard deviations that Cohen (1988) characterized as "small." For example, an evaluation of Response to Intervention from the Institute of Education Sciences (IES) detected impacts ranging from 0.13 to 0.17 standard…

Given the widespread use of non-experimental (NE) methods for assessing program impacts, there is a strong need to know whether NE approaches yield causally valid results in field settings. In within-study comparison (WSC) designs, the researcher compares treatment effects from an NE with those obtained from a randomized experiment that shares the…

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…

The current text comments on three systematic reviews published in the special section "Issues and Advances in the Systematic Review of Single-Case Research: An Update and Exemplars." The commentary is provided in relation to the need to combine the assessment of the methodological quality of the studies included in systematic reviews,…

In social sciences, the use of stringent methodological approaches is gaining increasing emphasis. Researchers have recognized the limitations of cross-sectional, non-manipulative data in the study of causality. True experimental designs, in contrast, are preferred as they represent rigorous standards for achieving causal flows between variables.…

The purpose of this study is to disseminate the results of recent advances in statistical power analyses with regard to multilevel mediation and its implementation in the PowerUp!-Mediator software. The authors first focus on the conceptual and statistical differences among common asymptotic, component-wise, and resampling-based tests of mediation…

The purpose of this paper is to present results of recent advances in power analyses to detect the moderator effects in Cluster Randomized Trials (CRTs). This paper focus on demonstration of the software PowerUp!-Moderator. This paper provides a resource for researchers seeking to design CRTs with adequate power to detect the moderator effects of…

Based on the increasing interest in systematic reviews and meta-analyses of Single-Subject Experimental Designs (SSEDs), the aim of the present review is to determine the general characteristics of these meta-analyses, including design characteristics of the primary studies and the meta-analyses, the kind of data, and the kind of analysis. After a…

Single-case design is a repeated-measures research approach for the study of the effect of an intervention, and its importance is increasingly being recognized in education and psychology. We propose a Bayesian approach for estimating intervention effects in SCD. A Bayesian inference does not rely on large sample theories and thus is particularly…

Cognitive behavioral therapy is a widely studied and commonly used psychosocial intervention for treating emotional problems in individuals with autism. To date, most studies of cognitive behavioral therapy and autism have focused on "efficacy." "Effectiveness" trials, by contrast, measure whether an intervention produces…

Purpose: The article reconsiders and explicates the role of academia within and for society and suggests quality standards for normative research. Approach: The article analyses and discusses transdisciplinary procedures for citizenship education research in democracies. Findings: Paradigmatic decisions concerning ontology, axiology, epistemology,…

Graphene is a novel material with extraordinary promise in various nano-based applications, including increases in strength, conductivity, filtration, and electrical capacity. Graphene can be synthesized and tested in a wide variety of applications in secondary or undergraduate settings. Allowing students to choose their own application and method…
