The potential association between psychosis and violence to others has long been debated. Past research findings are mixed and appear to depend on numerous potential moderators. As such, the authors conducted a quantitative review (meta-analysis) of research on the association between psychosis and violence. A total of 885 effect sizes (odds…

Purpose: This paper aims to explore and describe the limits of recent law-based school reform in South Africa from an education management perspective. Design/methodology/approach: The research design consists of a qualitative, investigative, descriptive and contextual design which Merriam would classify as a basic or generic design type.…

Psychologists have discovered a phenomenon called "Belief Bias" in which subjects rate the strength of arguments based on the believability of the conclusions. This paper reports the results of a small qualitative pilot study of undergraduate students who had previously taken an algebra-based introduction to statistics class. The subjects in this…

Bryophytes were among the earliest colonizers of terrestrial environs, and despite their interesting life histories and population dynamics, they are rarely used in undergraduate introductory biology labs. In an inquiry-based laboratory exercise for introductory biology, students implement a controlled experiment to investigate effects of…

How do evaluation practitioners make choices when they evaluate a program? What function do evaluation theories play in practice? In this article, I report on an exploratory study that examined evaluation practices in France. The research began with observations of practitioners' activities, with a particular focus on the phases of evaluation…

The present study aimed at finding the effectiveness of the Laboratory Training Model of Teaching (LTM) and comparing it with the traditional methods of teaching chemistry to seventh standard students. It strived to determine whether the (LTM) method in chemistry would be significantly more effective than the Traditional method in respect to the…

It can reasonably be said that the discussion board is the "heart" of an online course. The discussion board can and should help the learner to make meaning of the content or topic and to find relevance to their lives. When this "engagement" does not occur, the individual does not benefit from the discussion, and it becomes…

With the dominance of the Web in education and English language learning, new literacies have emerged. This thesis is motivated by the assumption that these literacies need to be integrated into the Egyptian pre-service EFL teacher education programmes so that EFL student teachers can cope with the new reality of language teaching/learning.…

A growing body of research suggests that the writing ability of international second language learners (IL2) and US-resident second language learners, also referred to as Generation 1.5 (G1.5), differs, despite a dearth of substantial empirical evidence supporting such claims. The present study provides much-needed empirical evidence concerning…

A well-designed experiment is the best method for establishing efficacy of any intervention, be it medical, behavioral, or educational in nature. This paper reviews the steps necessary in conducting a comparative experiment in an educational setting, and illustrates how these steps might be fulfilled within the context of a large-scale randomized…

This article describes the research design of, and reports selected findings from, a scoping study aimed at examining current and planned applications of 3D immersive virtual worlds at higher education institutions across Australia and New Zealand. The scoping study is the first of its kind in the region, intended to parallel and complement a…

Calculating and reporting appropriate measures of effect size are becoming standard practice in psychological research. One of the most common scenarios encountered involves the comparison of 2 groups, which includes research designs that are experimental (e.g., random assignment to treatment vs. placebo conditions) and nonexperimental (e.g.,…

Despite the plethora of papers reporting evidence from studies examining aspects of child development, there was until quite recently a dearth of literature on the ethical implications of research involving children and vulnerable groups. To inform the debate, this paper begins by drawing a distinction between ethical and methodological approaches…

The legal preparedness of preservice teachers has a longstanding history that consists of nonempirical findings and published research, including dissertations. This slowly evolving body of literature and research has been clouded by unsubstantiated claims and studies of weak research design. This article attempts to unravel the literature from…

Because of the variability exhibited by individual animals' responses to their environment, studying animal behavior can be a wonderful way to engage students in self-directed, open-inquiry investigations. Individual animals react in ways that are a combination of instinct and learned behavior, but collectively they exhibit broader tendencies that…
