Is Effective Teacher Evaluation Sustainable? Evidence from DCPS
Ten years ago, many policymakers viewed the reform of teacher evaluation as a highly promising mechanism to improve teacher effectiveness and student achievement. Recently, that enthusiasm has dimmed as the available evidence suggests the subsequent reforms had a mixed record of implementation… more →
Gender Stereotypes in the Classroom and Effects on Achievement
We study the effect of elementary school teachers’ beliefs about gender roles on student achievement. We exploit a natural experiment where teachers are prevented from self-selecting into schools, and conditional on school, students are allocated to teachers randomly. We show that girls who are… more →
Fostering Patience in the Classroom: Results from Randomized Educational Intervention
We evaluate the impact of a randomized educational intervention on children’s intertemporal choices. The intervention aims to improve the ability to imagine future selves, and encourages forward-looking behavior using a structured curriculum delivered by children’s own trained teachers. We find… more →
Mitigating the Gender Gap in the Willingness to Compete: Evidence from a Randomized Field Experiment
We evaluate the impact on competitiveness of a randomized educational intervention that aims to foster grit, a skill that is highly predictive of achievement. The intervention is implemented in elementary schools, and we measure its impact using a dynamic competition task with interim… more →
Ever Failed, Try Again, Succeed Better: Results from a Randomized Educational Intervention on Grit
We show that grit, a skill that has been shown to be highly predictive of achievement, is malleable in childhood and can be fostered in the classroom environment. We evaluate a randomized educational intervention implemented in two independent elementary school samples. Outcomes are measured via… more →
Teacher evaluation for accountability and growth: Should policy treat them as complements or substitutes?
Teacher evaluation policies seek to improve student outcomes by increasing the effort and skill levels of current and future teachers. Current policy and most prior research treats teacher evaluation as balancing two aims: accountability and skill development. Proper teacher evaluation design… more →
The effects of higher-stakes teacher evaluation on office disciplinary referrals
Despite frequent political and policy debates, the effects of imposing accountability pressures on public school teachers are empirically indeterminate. In this paper, we study the effects of accountability in the context of teacher responses to student behavioral infractions in the aftermath of… more →
How much can we remedy very low learning levels in rural parts of low-income countries? Impact and generalizability of a multi-pronged para-teacher intervention from a cluster-randomized trial in The Gambia
Despite large schooling and learning gains in many developing countries, children in highly deprived areas are often unlikely to achieve even basic literacy and numeracy. We study how much of this problem can be resolved using a multi-pronged intervention combining several distinct interventions… more →
Nearly three decades into the charter school movement, what has research told us about charter schools?
When charter schools first entered the landscape, the debate was contentious, with both advocates and critics using strong rhetoric. Advocates often sold charter schools as a silver bullet solution for not only the students who attend these schools, but the broader traditional public school… more →
Students with Growth Mindset Learn More in School: Evidence from California’s CORE School Districts
While the importance of social-emotional learning for student success is well established, educators and researchers have less knowledge and agreement about which social-emotional skills are most important for students and how these skills distribute across student subgroups.
Heterogeneous Effects of Early Algebra across California Middle Schools
How should schools assign students to more rigorous math courses so as best to help their academic outcomes? We identify several hundred California middle schools that used 7th grade test scores to place students into 8th grade Algebra courses, and use a regression discontinuity design to… more →
Child beliefs, societal beliefs, and teacher-student identity match
Children routinely benefit from being assigned a teacher who shares an identity with them, such as gender or ethnicity. We study how student beliefs impact teacher-student gender match effects, and how this varies across subjects with different societal beliefs about differential ability by… more →
The Long-Run Impacts of Special Education
Over 13 percent of US students participate in Special Education (SE) programs annually, at a cost of $40 billion. However, the effect of SE placements remains unclear. This paper uses administrative data from Texas to examine the long-run effect of reducing SE access. Our research design… more →
The Factors of Teacher Attrition and Retention: An Updated and Expanded Meta-Analysis of the Literature
Building on a previous meta-analysis of the literature on teacher attrition and retention by leveraging studies with longitudinal data and a modern systematic search process, this updated comprehensive meta-analysis synthesizes findings from 120 studies on the factors of teacher attrition and… more →
School Sector and Satisfaction: Evidence from a Nationally Representative Sample
Access to private schools and public charter schools might improve parent and student satisfaction through competitive pressures and improved matches between educators and students. Using a nationally representative sample of 13,436 students in the United States in 2016, I find that public… more →
My Brother’s Keeper? The Impact of Targeted Educational Supports
The My Brother’s Keeper (MBK) Challenge developed by President Obama supports communities that promote civic initiatives designed to improve the educational and economic opportunities specifically for young men of color. In Oakland, California, the MBK educational initiative features the African… more →
Can Technology Transform Communication between Schools, Teachers, and Parents? Evidence from a Randomized Field Trial
We study the adoption and implementation of a new mobile communication app among a sample of 132 New York City public schools. The app provides a platform for sharing general announcements and news as well as engaging in personalized two-way communication with individual parents. We provide… more →
The Impact of Low-Ability Peers on Cognitive and Non-Cognitive Outcomes: Random Assignment Evidence on the Effects and Operating Channels
This paper presents new experimental estimates of the impact of low-ability peers on own outcomes using nationally representative data from China. We exploit the random assignment of students to junior high school classrooms and find that the proportion of low-ability peers, defined as having… more →
Teacher peer observation and student test scores: Evidence from a field experiment in English secondary schools
This paper reports improvements in teacher job performance, as measured by student test scores, resulting from a program of (zero-) low-stakes peer evaluation. Teachers working at the same school observed and scored each other’s teaching. Students in randomly-assigned treatment schools scored 0.… more →
Self-Management Skills and Student Achievement Gains: Evidence from California’s CORE Districts
Existing research on self-management skills shows that measures of self-management predict student success. However, these conclusions are based on small samples or narrowly defined self-management measures. Using a rich longitudinal dataset of 221,840 fourth through seventh grade students, this… more →
