Universal school-based programs to reduce or prevent violent behavior are delivered to all children in classrooms in a grade or in a school. Similarly, programs targeted to schools in high-risk areas (defined by low socioeconomic status or high crime rates) are delivered to all children in a grade or school in those high-risk areas. During…

Plants are essential to life on Earth and yet are often deemed invisible by the human populace. Botanic gardens are an under-researched educational context and, as such, have occupied a peripheral arena in biology education discussions. This article seeks to readdress this absence and present the case for a more sustained use of informal learning…

This article argues that "transition" offers a limited and outmoded conceptual frame for understanding young people's engagement with work and learning. It draws on two studies of young people to provide insights into the study and work experiences of older and school-aged youth. Our analysis suggests that rather than focussing narrowly…

Professionals in the field of deaf-blindness are challenged to use instructional practices that have been tested using experimental methodology. Single-subject design has been examined as a form of research that assists in substantiating practice. In a review of the literature, the authors identified 54 single-subject studies from 1969 to 2006…

The job satisfaction-job performance relationship has attracted much attention throughout the history of industrial and organizational psychology. Many researchers and most lay people believe that a causal relationship exists between satisfaction and performance. In the current study, however, analyses using meta-analytic data suggested that the…

Recent governments in the United Kingdom have introduced a number of initiatives aimed at improving the literacy levels of children. Policy and practice should be informed by rigorous evidence, and this evidence should be subjected to critical scrutiny. In the present paper the results of a "tertiary" review of systematic reviews in…

The purpose of this meta-analysis was to quantify the relationship between the Five-Factor Model of personality and alcohol involvement and to identify moderators of the relationship. The meta-analysis included 20 studies, 119 effect sizes, and 7,886 participants. Possible moderators examined included: five-factor rating type (self vs. other);…

This paper provides a metareview of how e-learning content is currently being produced and embedded in the learning practice in further education, work-based learning and community learning contexts. Based upon this metareview, the paper has identified four categories of content production used: (1) learner-authored content, (2)…

IQ scores provide the best general predictor of success in education, job training, and work. However, there are many ways in which IQ scores can be increased, for instance by means of retesting or participation in learning potential training programs. What is the nature of these score gains? Jensen [Jensen, A. R. (1998a). "The g factor: The…

This study compared different stakeholders' perceived validity of various indicators of student learning used to judge the quality of students' academic performance. Data were gathered from the questionnaire responses of 314 educators in three states that have implemented comprehensive state-wide assessment programs with high-stakes consequences…

The test of homogeneity developed by L. V. Hedges (1982) for the fixed effects model is frequently used in quantitative meta-analyses to test whether effect sizes are equal. Despite its widespread use, evidence of the behavior of this test for the less-than-ideal case of small study sample sizes paired with large numbers of studies is…

Sex differences in language use have been examined for many years, but no clear-cut conclusions exist. A meta-analysis of the existing literature was conducted regarding powerful/powerless language use, including 30 studies, with a total combined sample size of 3,012. The overall correlation indicated that men use more powerful language than…

Using meta-analysis, this research takes a look at studies included in a meta-analysis by R. Jaeger (1989) that compared the cut score set by one standard setting method with that set by another. This meta-analysis looks beyond Jaeger's studies to select 10 from the research literature. Each compared at least two types of standard setting method.…

How nursing science researchers conducting mixed method triangulation are using the heterogeneity of irrelevancy assumption in practice was studied. Seven questions were developed to reflect the implications for practice of the heterogeneity assumption. Answers to these questions were obtained from 23 written cases (14 articles, 1 presentation,…

A quantitative method, meta-analysis, is used to integrate research findings from a representative group of 38 coaching studies. Because different studies reported results on different scales, effect size was used to transform all results to a common metric. This meta-analysis showed that there are two distinct literatures on the effectiveness of…
