Given growing awareness of the high prevalence of food insecurity among college students, higher education leaders are implementing various food interventions on their campuses. However, there is little research on the efficacy and impact of these initiatives. Using data from a field randomized control trial, we find that a relatively modest…

A substantial number of randomized trials of educational interventions that have been conducted over the past two decades have produced null results, with either no impact or an unreliable estimate of impact on student achievement or other outcomes of interest. The investment of time and money spent implementing such trials warrants more useful…

In the current article, we examine the long-run school selection patterns of children randomly assigned to the Chicago School Readiness Project, an early childhood educational (ECE) intervention that aimed to improve the quality of Head Start classrooms serving low-income communities. Analyses suggest that adolescents who participated in the…

Why, when so many educational interventions demonstrate positive impact in tightly controlled efficacy trials, are null results common in follow-up effectiveness trials? Using case studies from literacy, this article suggests that replication failure can surface hidden moderators--contextual differences between an efficacy and an effectiveness…

Grit is a construct that is widely studied by educational researchers and that has generally been enthusiastically received by educational practitioners. This essay highlights that many of the core claims about grit have either been unexamined or are directly contradicted by the accumulated empirical evidence. Specifically, there appears to be no…

Poor program implementation constitutes one explanation for null results in trials of educational interventions. For this reason, researchers often collect data about implementation fidelity when conducting such trials. In this article, we document whether and how researchers report and measure program fidelity in recent cluster-randomized trials.…

Many states mandate districts or schools notify parents when students have missed multiple unexcused days of school. We report a randomized experiment (N = 131,312) evaluating the impact of sending parents truancy notifications modified to target behavioral barriers that can hinder effective parental engagement. Modified truancy notifications that…

One commonly used strategy used in attempts to decrease racial disproportionality in school discipline across the country is sharing data with school administrators that discipline disparities are a problem in their schools with the assumption that it will increase attention to equity and improve outcomes. The purpose of this study was to assess…

National and state assessments show that English language learners (ELs) in elementary and secondary grades score lower in mathematics compared with their matched English proficient peers (EPs). To provide information on strategies for enhancing learning opportunities for ELs in language inclusive classrooms, we analyze the efficacy of…

An analysis was conducted of the What Works Clearinghouse (WWC) research evidence base on the effectiveness of replicable education interventions. Most interventions were found to have little or no support from technically adequate research studies, and intervention effect sizes were of questionable magnitude to meet education policy goals. These…

This article synthesizes the current research on bullying prevention and intervention in order to provide guidance to schools seeking to select and implement antibullying strategies. Evidence-based best practices that are shared across generally effective antibullying approaches are elucidated, and these strategies are grounded in examples…

The College Ambition Program (CAP) is designed to encourage low-income and minority students to enroll in college. The following analysis presents updated results from my AERA presidential talk in 2014. Results indicate that CAP, which is a schoolwide intervention, increased college attendance for low-income and minority students in seven…

Commentaries regarding appropriate methods for researching professional development have been a frequent topic in recent issues of "Educational Researcher" as well as other venues. In this article, the authors extend this discussion by observing that randomized trials of specific professional development programs have not enhanced our…

Education researchers, practitioners, and policymakers alike are committed to identifying interventions that teach students more effectively. Increased emphasis on evaluation and accountability has increased desire for sound evaluations of these interventions; and at the same time, school-level data have become increasingly available. This article…
