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…

This article provides evidence about predictive relationships between features of community college interventions and their impacts on student progress. This evidence is based on analyses of student-level data from large-scale randomized trials of 39 (mostly) community college interventions. Specifically, the evidence consistently indicates that…

The randomized trial of the Making Socially Accepting Inclusive Classrooms (MOSAIC) program included intensive coaching from research staff to support teachers' implementation of MOSAIC strategies and resulted in positive student outcomes (Mikami et al., J. Clin. Child Adolesc. Psychol. 51(6):1039-1052, 2022). However, these intensive procedures…

This study investigates the impact of Education Endowment Foundation (EEF)-funded trials on pupils eligible for free school meals. Although similar analysis is conducted during each individual evaluation, this report conducts a meta-analysis using data from 88 trials and over half a million pupils to reach conclusions. The report contributes to…

Perfectionism has adverse impacts on mental health and academic outcomes. We evaluated a 5-lesson classroom intervention for young adolescents delivered by teachers for impact on perfectionism, well-being, self-compassion, academic motivation and negative affect, at post-intervention and 3-month follow-up. Classes (N = 636 students, M[subscript…

In this study, we used a randomized control trial (N = 84) to evaluate the effects of a classroom-based motivational interviewing intervention on undergraduate psychology students' test performance. Results indicated that students in the treatment group (n = 38) demonstrated significant increases in their exam grades following the intervention (d…

Randomized controlled trials in lower-income countries have demonstrated ways to increase learning, in specific settings. This study uses a large-scale, nationwide RCT in Ghana to show the external validity of four school-based interventions inspired by other RCTs. Even though the government implemented the programs within existing systems,…

Background: It has become increasingly important to shift education research and programming from a deficit focused perspective to a positive youth development perspective in order to identify and promote factors that support students' positive functioning and outcomes. One outgrowth of positive youth development is Positive Mental Health (PMH),…

To plan cluster-randomized trials with sufficient statistical power to detect intervention effects on student achievement, researchers need multilevel design parameters, including measures of between-classroom and between-school differences and the amounts of variance explained by covariates at the student, classroom, and school level. Previous…

Objective: The current study reports functional outcomes from a multi-site randomized trial of a cognitive-behavioral treatment program for college students diagnosed with ADHD. Methods: A sample of emerging adults (N = 250; ages 18 to 30) currently attending college were comprehensively evaluated and diagnosed with ADHD (M age = 19.7; 66% female,…

Students with disabilities are often included in general education social studies classes, but these classes can differ in the achievement level of the overall class, including wide variation in content-related background knowledge, reading achievement, or both. The purpose of this study was to examine how background knowledge and reading…

The purpose of this study was to examine the effects of proactive student-success coaching, informed by predictive analytics, on student academic performance and persistence. Specifically, semester GPA and semester-to-semester student persistence were the investigated outcomes. Uniquely, the community college focused the intervention on only…

This document presents the testimony of MDRC's Alex Mayer, the Deputy Director for Postsecondary Education at MDRC. The three points that Alex Mayer emphasizes in this testimony before the California State Assembly Higher Education Committee and the Budget Subcommittee on Education Finance on integrating postsecondary education interventions to…

A habitually active environment is a feature of past times, and in stark contrast with that experienced by our children today. Consequently, twenty-first century physical education (PE) assumes a position of great responsibility. This is especially true in primary schools; a premise recently strongly supported by published evidence from the…
