A Monte Carlo study extended the research of MacKinnon, Lockwood, Hoffman, West, and Sheets (2002) for single-level designs by examining the statistical performance of four methods to test for mediation in a multilevel experimental design. The design studied was a two-group experiment that was replicated across several sites, included a single…

In an experimental design involving two auditorily presented competing commands (one to each ear), 144 right-handed subjects (72 male and 72 female) were asked to provide motor responses. Half of each group of subjects was responding with their right hand and the other half with the left. The test was applied in the subjects' native language…

In this article, I argue that when design and intervention are central to the research process, context as a construct is problematized. How we define context can facilitate or impede our ability to construct rich and veridical accounts of learning. A design stance may predispose us to less profitable notions of context. I present the advantages…

The world regards AIDS as the most disastrous health threat in the world. HIV/AIDS- related issues amongst adolescents were initially neglected due to the visible impact of this pandemic on babies and adults. Adolescents' behavior is however regarded as high-risk because of their involvement in sexual activities from a young age. The purpose of…

Although recent evidence suggests that non-cognitive skills such as engagement matter for academic and economic success, there is little evidence on how key educational inputs affect the development of these skills. We present a re-analysis of follow-up data from the Project STAR class-size experiment and find evidence that early-grade class-size…

In spite of the relative success of equal opportunity laws on women's status in the workplace, we know little about the influence of such legal interventions on people's attitudes and beliefs. This paper focuses, in particular, on how sexual harassment policy affects men's beliefs about the gender hierarchy. We employ an experimental design in…

Learning how to conduct qualitative research may seem daunting for those new to the task, especially given the paradigm's emphasis on complexity and emergent design. Although there are guidelines in the literature, each project is unique and ultimately the individual researcher must determine how best to proceed. Reflexivity is thus considered…

This commentary considers some of the challenges of applying mixed methods research in undergraduate research degrees, especially in professions with a clinical health focus. Our experience in physiotherapy academia is used as an example. Mixed methods research is increasingly appreciated in its own right as a "third paradigm," however the success…
