The Implicit Association Test (IAT) is increasingly used in developmental research despite minimal evidence of whether children's IAT scores are reliable across time or predictive of behavior. When test-retest reliability and predictive validity have been assessed, the results have been mixed, and because these studies have differed on many…

The Student Climate and Conservation Congress (SC3) is a joint educational effort between the United States Fish and Wildlife Service and the Green Schools Alliance that aims to develop the next generation of conservation leaders through fostering action competence in youth.

Among the protective factors associated with reduced risk for suicide, scientific inquiries into school connectedness are especially important considering that schools are ideally situated to provide interventions reaching the vast majority of youth. Although there is a wealth of research that supports the association between school connectedness…

School-based victimization is associated with poorer developmental, academic, and health outcomes. This meta-analytic review compared the mean levels of school-based victimization experienced by sexual minority youth to those of heterosexual youth, and examined moderators of this difference. Results from 18 independent studies (N = 56,752…

In this meta-analysis, we systematically reviewed research on digital games and learning for K-16 students. We synthesized comparisons of game versus nongame conditions (i.e., media comparisons) and comparisons of augmented games versus standard game designs (i.e., value-added comparisons). We used random-effects meta-regression models with robust…

We review the effectiveness of first-year seminars based on the widely used criteria of first-year grades and the 1-year retention rate. Meta-analytic results indicate that first-year seminars have a small average effect on both first-year grades (k = 89, N = 52,406, d = 0.02) and the 1-year retention rate (k = 195, N = 169,666, d = 0.11). We…
