The Effects of An Automatic Notification Tool to Increase Participation in Advanced High School Courses: Results from a Large-Scale Cluster Randomized Controlled Trial
Taking advanced courses in high school is associated with many positive high school and college outcomes. States and school districts are increasingly interested in more systematic approaches to identify qualified students for advanced course work. We developed an automatic notification tool,… more →
School Finance in the US
Topics: Policy, Politics, and GovernanceThis chapter provides an overview of K-12 public school finance in the United States by tracing how funding systems changed over time, how they operate today, and how well they advance core policy goals. Section 2 documents the long-run shift from local property tax finance toward larger state… more →
Classroom Composition Affects Teacher Performance Ratings
Topics: Teacher and Leader DevelopmentTeacher evaluations should reflect teaching performance rather than the characteristics of the students assigned to a teacher. Exploiting naturally occurring year-to-year variation in classroom composition within teachers, this paper examines whether teacher performance ratings assigned by… more →
Why Fadeout is (Probably) Worse Than We Think: Adjusting for Correlated Sampling Error in Meta-Analyses of Behavioral Interventions
Topics: MethodsThe extent to which intervention effects persist or fade over time is an important question in the behavioral sciences. In meta-analysis, persistence is typically assessed by meta-regressing effect sizes at followup on effect sizes at endline. While common, the standard meta-regression does not… more →
The Trade-off between Quality and Quantity: Evidence from a Field Experiment on Tutoring
Topics: Student LearningHigh-dosage tutoring has the potential to substantially raise adolescent academic achievement. However, at scale, schools may not have the financial ability to deliver small-group tutoring frequently. In this paper, I test the relative importance of group size (quality) versus tutoring frequency… more →
Mapping the Mechanisms of Interdisciplinary Learning Transfer from Reading to Math Achievement: Evidence from a Large-Scale Randomized Controlled Trial
Topics: Student LearningFar transfer---the application of learning across distant domains---remains elusive in intervention research, and even when it is found, its mechanisms remain unclear or unexplored. This study analyzes data from the Model of Reading Engagement (MORE), a sustained content literacy intervention… more →
Scaling High-Touch College Advising: Causal Evidence and Program Design Insights from Tennessee
College advising can raise postsecondary enrollment, but few programs prove effective at scale. We leverage the rollout of a statewide, professionally staffed, and centrally coordinated college advising program (Advise TN) across 33 communities to estimate causal impacts on enrollment,… more →
How General is Educational Intervention Fadeout? A Meta-Analysis of Educational RCTs with Follow-Up
Topics: Policy, Politics, and GovernanceResearchers and policymakers pursue educational interventions with the goal of altering children’s long-term trajectories. However, many effects fade quickly after interventions end. Researchers have sought to address the fadeout problem by identifying characteristics of interventions that lead… more →
Cheaper (and more effective) by the dozen: Evidence from 12 randomized A/B tests optimizing tutoring for scale
Topics: Student LearningOver the course of 12 rapid randomized experiments, we optimize an educational tutoring program. Tutoring is one of the most effective educational approaches yet has remained difficult to scale due to high costs. We adaptively test and improve a technology-enabled tutoring program to enhance… more →
Comparative Cost Analyses of Community College Student Success Initiatives
Limited resources hinder completion and exacerbate inequality in community colleges. Existing research identifies strategies that raise outcomes but leaves policymakers and campus leaders asking, “What do these interventions really cost—and can we afford it?” I answer these questions by… more →
Reclaiming Educational Fraud and Waste: A Conceptual Framework to Locate the True Sources of Resource Leakage and Harm in The U.S. K-12 System
Topics: Policy, Politics, and GovernanceThe recent dismantling of federal educational institutions has been legitimated under the banner of “eliminating fraud and waste.” In this paper, we reclaim these terms to locate the sources of potential fraud and waste in the U.S. K-12 education system through a novel conceptual framework that… more →
High School Effects on Civic Engagement
Topics: Policy, Politics, and GovernancePreparing young people for citizenship is a foundational purpose of public education, yet little is known about whether or how K-12 schools impact civic engagement. Using education, birth, and voting records for nine cohorts of students in Indiana, I estimate and assess the validity of high… more →
Efficacy of Zearn Math over two years in grades 3 to 5: An experiment in Texas
Topics: Student LearningZearn Math is a popular software platform for K-8 mathematics learning, designed to enable all students to successfully access grade-level content. RAND researchers collaborated with Zearn, the product’s developer, to design this evaluation. Then RAND conducted the study independently, randomly… more →
Item-Level Heterogeneity in Value Added Models: Implications for Reliability, Cross-Study Comparability, and Effect Sizes
Topics: MethodsTags: Assessment, EfficacyValue added models (VAMs) attempt to estimate the causal effects of teachers and schools on student test scores. We apply Generalizability Theory to show how estimated VA effects depend upon the selection of test items. Standard VAMs estimate causal effects on the items that are included on the… more →
Disparate Teacher Effects, Comparative Advantage, and Match Quality
Topics: MethodsDoes student-teacher match quality exist? While prior research documents disparities in teachers' impacts across student types, it has not distinguished between sorting and causal effects as the drivers of these disparities. I develop a flexible disparate value-added model (DVA) and introduce a… more →
From Passive Promises to Proactive Guarantees: The Efficacy of Financial Certainty Interventions Among Automatically (In-)Admissible Students
Low-income high-achieving students are less likely than high-income peers to enroll in selective colleges. Financial certainty interventions can address administrative burdens that stifle their enrollment, even when colleges are tuition-free for them. However, we do not know whether these… more →
Exploring the Potentials of Outcomes-Based Contracting: Findings from Initial Implementations
Outcomes-Based Contracting (OBC) ties vendor payments to performance metrics, aiming to enhance accountability in public education. This study examines its implementation in tutoring services through the Southern Education Foundation pilot program. Interviews with district leaders and vendors… more →
How Not to Fool Ourselves About Heterogeneity of Treatment Effects
Topics: MethodsTags: EfficacyResearchers across many fields have called for greater attention to heterogeneity of treatment effects—shifting focus from the average effect to variation in effects between different treatments, studies, or subgroups. True heterogeneity is important, but many reports of heterogeneity… more →
Exploring the Move Away from ‘Zero -Tolerance’ Policies: Evidence from Restorative Justice Practices in Texas and Michigan Schools
Topics: Policy, Politics, and GovernanceThis study examines the impact of statewide Restorative Justice (RJ) policy reforms in Michigan and Texas on student disciplinary outcomes and behavior, in light of increasing concerns over the negative effects of zero-tolerance policies. As schools move away from exclusionary discipline… more →
Skills and Earnings: A Multidimensional Perspective on Human Capital
Topics: Student LearningThe multitude of tasks performed in the labor market requires skills in many dimensions. Traditionally, human capital has been proxied primarily by educational attainment. However, an expanding body of literature highlights the importance of various skill dimensions for success in the labor… more →
