As past studies showed mixed results, this meta-analysis determined game-based learning's overall effect on students' critical thinking and tested for moderators, using 21 effect sizes from 20 empirical studies of 1,947 participants. The results showed that game-based learning had a significant positive overall effect on students' critical…

Recently, researchers have begun associating personal epistemology with self-regulated learning. Therefore, in the literature there is a need to examine what degree the studies have supported the relationship between the two. The purpose of this meta-analysis is two folds: a) to compute the mean effect size for the relations between personal…

This study's aim is to measure the effect sizes of the quantitative studies that examined the effectiveness of brain-based learning on students' academic achievement and to examine with the meta-analytical method if there is a significant difference in effect in terms of the factors of education level, subject matter, sampling size, and the…

A recent meta-analysis of 164 terror management theory (TMT) papers indicated that mortality salience (MS) yields substantial effects (r = 0.35) on worldview and self-esteem-related dependent variables (B. L. Burke, A. Martens, & E. H. Faucher, 2010). This study reanalyzed the data to explore the researcher effects of TMT. By cluster-analyzing…

A growing body of research suggests that mindfulness- and acceptance-based principles can increase efforts aimed at reducing human suffering and increasing quality of life. A critical step in the development and evaluation of these new approaches to treatment is to determine the acceptability and efficacy of these treatments for clients from…

The literature on male-female differences in burnout has produced inconsistent results regarding the strength and direction of this relationship. Lack of clarity on gender differences in organizationally relevant phenomena, such as work burnout, frequently generates ungrounded speculations that may (mis)inform organizational decisions. To address…

A gender gap in mathematics achievement persists in some nations but not in others. In light of the underrepresentation of women in careers in science, technology, mathematics, and engineering, increasing research attention is being devoted to understanding gender differences in mathematics achievement, attitudes, and affect. The gender…

Researchers have suggested the presence of a self-serving attributional bias, with people making more internal, stable, and global attributions for positive events than for negative events. This study examined the magnitude, ubiquity, and adaptiveness of this bias. The authors conducted a meta-analysis of 266 studies, yielding 503 independent…

The prevailing view in popular culture and the psychological literature is that White women have greater body dissatisfaction than women of color. In this meta-analysis, 6 main effect sizes were obtained for differences among Asian American, Black, Hispanic, and White women with a sample of 98 studies, yielding 222 effect sizes. The average d for…

Used meta-analysis to examine premise that the early child-parent bond is reflected in interpersonal relationships across the life span. Found that overall effect size (ES) for child-mother attachment was small to moderate. ESs were similar in studies using Strange Situation and Q-sort methods. ESs were larger for middle childhood and adolescent…
