In this project, the researchers will employ a meta-analysis of rigorous studies conducted during the 21st century to assess the effects of nudging interventions on students' enrollment, persistence, and degree completion in postsecondary education, to draw clear conclusions to the mixed set of findings that have emerged from postsecondary nudging studies. Many researchers and decisionmakers in postsecondary education view nudging interventions, popularized in the behavioral economics litera...

In this project, the researchers will conduct a living systematic review (LSR) of evidence to transform the availability of, and access to, contemporary research evidence for universal school-based (USB) social-emotional learning (SEL) programs in the United States. An LSR is a continuously cumulative evidence synthesis that allows for up-to-date findings that change over time with the corpus of studies available. There is an urgent need to restore public confidence in the evidence to addres...

The most popular meta-analytic methods have serious limitations in diagnosing and adjusting for selective reporting, especially when there are dependencies among multiple effects from primary studies, a widespread occurrence. For meta-analysis of independent effects, selection models have shown promise in flexibly capturing complex reporting patterns while providing adjusted meta-analytic estimates, but no existing model also simultaneously addresses effect size dependencies. The purpose of ...

Researchers in this study conducted a systematic review to identify rigorous studies of interventions aimed to improve English learner (EL) student learning outcomes and meta-analyze the studies. Researchers used meta-analysis to identify factors related to program effectiveness including characteristics of the studies and their methods, program features, outcome characteristics, sample characteristics, and study settings.

The research team conducted systematic literature review and meta-analysis to estimate the effects of different types of financial aid programs on college student outcomes from initial enrollment to post-college labor market outcomes.
