Teacher Strikes and the Demobilization of Republican Voters
Topics: Policy, Politics, and GovernanceProtests can mobilize both supporters and opponents. Extant research suggests that disruptive protests are particularly likely to mobilize opponents, yet strikes—one of the most disruptive forms of protest—have been largely absent from this literature. We use an original dataset of 716 teacher… more →
How Powerful Are Promises? A Systematic Review of the Causal Mechanisms and Outcomes of "Free College" Programs in the United States
Tags: Higher education, Efficacy“Free college” (sometimes called Promise) programs are common in U.S. higher education. Reviewing 88 studies of 25 state and local programs, I provide a nuanced picture of the mechanisms through which these programs may work and their likely effects on students, communities, and colleges. Some… more →
Does One Plus One Always Equal Two? Examining Complementarities in Educational Interventions
Topics: MethodsTags: Assessment, EfficacyPublic policies targeting individuals based on need often impose disproportionate burden on communities that lack the resources to implement these policies effectively. In an elementary school setting, I examine whether community-level interventions focusing on similar needs and providing… more →
What Works and For Whom? Effectiveness and Efficiency of School Capital Investments Across the U.S.
This paper identifies which investments in school facilities help students and are valued by homeowners. Using novel data on school district bonds, test scores, and house prices for 29 U.S. states and a research design that exploits close elections with staggered timing, we show that increased… more →
Experimental education research: clarifying why, how and when to use random assignment
Topics: MethodsTags: Efficacy, School reformOver the last twenty years, education researchers have increasingly conducted randomised experiments with the goal of informing the decisions of educators and policymakers. Such experiments have generally employed broad, consequential, standardised outcome measures in the hope that this would… more →
College Counseling in the Classroom: Randomized Evaluation of a Teacher-Based Approach to College Advising
Tags: College readiness, EfficacyGuidance counselors provide the main source of college advising for low-income high school students, but are woefully understaffed in high-need schools. This paper evaluates an approach to school-based college advising that relies on teachers rather than counselors. Using a randomized control… more →
Integrated Student Support Intervention Mitigates the Adverse Impact of School Mobility on Middle School Students' Achievement and Behavior
Topics: Policy, Politics, and GovernanceSchool mobility, compounding socioeconomic inequities, can undermine academic achievement and behavior, particularly during middle school years. This study investigates the effect of a school-based integrated student support intervention – City Connects – on the achievement and behavior of… more →
Out of Sight, Out of Mind? The Gap between Students’ Test Performance and Teachers’ Estimations in India and Bangladesh
This is one of the first studies of the mismatch between students’ test scores and teachers’ estimations of those scores in low- and middle-income countries. Prior studies in high-income countries have found strong correlations between these metrics. We leverage data on actual and estimated… more →
Employee evaluation and skill investments: Evidence from public school teachers
When employees expect evaluation and performance incentives will continue (or begin) in the future, the potential future rewards create an incentive to invest in relevant skills today. Because skills benefit job performance, the effects of evaluation can persist after the rewards end or even… more →
The Stubborn Unresponsiveness of Youth Voter Turnout to Civic Education: Quasi-experimental Evidence from State-Mandated Civics Tests
Topics: Policy, Politics, and GovernanceYouth voter turnout remains stubbornly low and unresponsive to civic education. Rigorous evaluations of the adoption of civic tests for high school graduation by some states on youth voter turnout remain limited. We estimate the impact of a recent, state-mandated civics test policy—the Civics… more →
Mandating Multiple Measures and Encouraging Student Supports: Evaluating a New Approach to Developmental Education in California’s Community Colleges
Tags: Higher education, EfficacyAB705 is a landmark higher education policy that has changed approaches to developmental/remedial education in the California Community College system. We study one district that implemented reforms by placing most students in transfer-level math/English courses and encouraging enrollment in… more →
At What Cost?: Is Technical Education Worth the Investment?
Career and technical education (CTE) has existed in the United States for over a century, and only in recent years have there been opportunities to assess the causal impact of participating in these programs while in high school. To date, no work has assessed whether the relative costs of these… more →
The Long-Run Impacts of Universal Pre-K with Equilibrium Considerations
Topics: Student LearningSince 1995, publicly funded pre-K with universal eligibility has proliferated across the U.S. Universal pre-K (UPK) operates at great scale and serves children with a wide range of alternative childcare options. Because these programs are relatively young, very little is known about their long-… more →
How Much Do Early Teachers Matter?
Topics: Student LearningTags: EfficacyWe present new estimates of the importance of teachers in early grades for later grade outcomes, but unlike the existing literature that examines teacher “fade-out,” we directly compare the contribution of early-grade teachers to later year outcomes against the contributions of later year… more →
Correspondence Measures for Assessing Replication Success
Topics: MethodsTags: EfficacyGiven recent evidence challenging the replicability of results in the social and behavioral sciences, critical questions have been raised about appropriate measures for determining replication success in comparing effect estimates across studies. At issue is the fact that… more →
Crossing the Finish Line but Losing the Race? Socioeconomic Inequalities in the Labor Market Trajectories of Community College Graduates
Despite decades and hundreds of billions of dollars of federal and state investment in policies to promote postsecondary educational attainment as a key lever for increasing the economic mobility of lower-income populations, research continues to show large and meaningful differences in the mid-… more →
Signal Weighted Value-Added Models
Topics: MethodsTags: Assessment, EfficacyThis study introduces the signal weighted teacher value-added model (SW VAM), a value-added model that weights student-level observations based on each student’s capacity to signal their assigned teacher’s quality. Specifically, the model leverages the repeated appearance of a given student to… more →
The Effects of Middle School Remediation on Postsecondary Success: Regression Discontinuity Evidence from Florida
Topics: Student LearningHigh school graduation rates in the United States are at an all-time high, yet many of these graduates are deemed not ready for postsecondary coursework when they enter college. This study examines the short-, medium-, and long-term effects of remedial courses in middle school using a regression… more →
The Distribution of School Spending Impacts
Tags: Efficacy, AssessmentWe examine all known "credibly causal" studies to explore the distribution of the causal effects of public K-12 school spending on student outcomes in the United States. For each of the 31 included studies, we compute the same marginal spending effect parameter estimate. Precision-weighted… more →
Improving Average Treatment Effect Estimates in Small-Scale Randomized Controlled Trials
Topics: MethodsTags: EfficacyResearchers often include covariates when they analyze the results of randomized controlled trials (RCTs), valuing the increased precision of the estimates over the potential of inducing small-sample bias when doing so. In this paper, we develop a sufficient condition which ensures that the… more →
