Background: Although past research demonstrated growth mindset interventions to improve school outcomes, effects were small. This may be due to the "theoretical" nature of psychosocial techniques (e.g., reading about brain plasticity), which may not be optimally convincing for students. Aims: To address this issue and improve…

Background: Despite many adolescents experiencing mental health concerns, a substantial portion lack access to evidence-based treatments (EBTs) for psychopathology; this issue is magnified for adolescents belonging to communities considered marginalized. One way to ameliorate this is by adapting existent EBTs--typically delivered in research…

Online credit recovery will likely expand in the coming years as school districts try to address increased course failure rates brought on by the coronavirus pandemic. Some researchers and policymakers, however, raise concerns over how much students learn in online courses, and there is limited evidence about the effectiveness of online credit…

Early work experiences are associated with subsequent employment for students with significant disabilities, but they rarely receive such opportunities. This article presents two case studies illustrating a school-based intervention that connected students with significant disabilities to paid work during high school and included training for…

Noncompliance to treatment assignment is widespread in randomized trials and presents challenges in causal inference. In the presence of noncompliance, the most commonly estimated effect of treatment assignment, also known as the intent-to-treat (ITT) effect, is biased. Of interest in this setting is the complier average causal effect (CACE), the…

Background: Over the past decade, schools across the United States increasingly turned to online learning (Gemin, Pape, Vashaw, & Watson, 2015; Queen & Lewis, 2011). While many espouse the promise of online credit recovery (OCR) courses, the abrupt shift to online learning during the COVID-19 pandemic renewed concerns about theses courses'…

Recent methods have sought to improve precision in randomized controlled trials (RCTs) by utilizing data from large observational datasets for covariate adjustment. For example, consider an RCT aimed at evaluating a new algebra curriculum, in which a few dozen schools are randomly assigned to treatment (new curriculum) or control (standard…

Background: Weight stigma is prevalent among adolescents and can negatively impact physical and mental health. This study examined the effects of a combined physical activity and attitude education intervention on weight stigma and related outcomes among high school students. Methods: A randomized controlled trial was conducted with 524 high…

We provide evidence about college financial aid from an eight-year randomized trial where high school ninth graders received a $12,000 merit-based grant offer. The program was designed to be free of tuition/fees at community colleges and substantially lower the cost of four-year colleges. During high school, it increased students' college…

The gold-standard for evaluating the effect of an educational intervention on student outcomes is running a randomized controlled trial (RCT). However, RCTs may often be small due to logistical considerations, and resulting treatment effect estimates may lack precision. Recent methods improve experimental precision by incorporating information…

Student-teacher relationships are important to student outcomes and may be especially pivotal at the high school transition and for minoritized racial/ethnic groups. Although interventions exist to improve student-teacher relationships, none have been shown to be effective among high school students or in narrowing racial/ethnic disparities in…
