This manuscript examines recent key texts and…

Effect Sizes (ES) are an increasingly important index used to quantify the degree of practical significance of study results. This paper gives an introduction to the computation and interpretation of effect sizes from the perspective of the consumer of the research literature. The key points made are: (1) "ES" is a useful indicator of the…

The year 2000 US presidential election between Al Gore and George Bush has been the most intriguing and controversial one in American history. The state of Florida was the trigger for the controversy, mainly, due to the use of the misleading "butterfly ballot". Using prediction (or confidence) intervals for least squares regression lines…

This article reflects upon the theories and methodologies that inform peace studies teaching and research practice. It explores the challenges faced by tertiary educators working within the narrowing confines of current university structures, and, by analysing the motives, process and methodologies that have shaped one particular program, suggests…

Despite the prevalence of multiple choice items in educational testing, there is a dearth of empirical evidence for multiple choice item writing rules. The purpose of this study was to expand the base of empirical evidence by examining the use of the "all-of-the-above" option in a multiple choice examination in order to assess how…

Evidence-based practice is highly valued in health care literature at this time. But research suggests that U.S. RNs face many obstacles when implementing evidence-based practice including a lack of value for research in practice (Pravikoff et al, 2005). Additional obstacles may exist for traditional U.S. BSN nursing students who may not value the…

This comparative study was designed to investigate how online and traditional face-to-face (FtF) students used different learning styles in a graduate educational course. A nonequivalent control group design was employed. The study involved 19 students in an experimental group (online section) and 25 students in a control group (FtF section) in a…

The purpose of this exploratory study was to investigate the relationship between functional communication and executive function ability in aphasia. Twenty-five participants with aphasia underwent examination with an extensive test battery including measures of functional communication, executive function ability, and language impairment.…

A new item parameter replication method is proposed for assessing the statistical significance of the noncompensatory differential item functioning (NCDIF) index associated with the differential functioning of items and tests framework. In this new method, a cutoff score for each item is determined by obtaining a (1-alpha ) percentile rank score…

Many extant studies on the use of non-parental child care are based on data from the youngest child in the household. To date, it has not been addressed whether this approach introduces bias. We present reasons why child care arrangements for youngest children may differ from those of same-age older children and examine whether the use of child…

The psychological literature currently emphasizes reporting the "effect size" of research findings in addition to the outcome of any tests of significance. However, some confusion may result from the fact that there are three distinct uses of effect sizes in the psychological literature, namely, power analysis, research synthesis, and research…
