Impacts of School Entry Age on Academic Growth through 2nd Grade: A Multi-State Regression Discontinuity Analysis
The belief that additional time allows children to become more ready for school has affected public policy and individual practices. Prior studies estimated either associations between school entry age and academic growth or causal effects on achievement measured at one or two points. This paper… more →
Timing in Early Childhood Education: How Cognitive and Achievement Program Impacts Vary by Starting Age, Program Duration, and Time Since the End of the Program
This paper uses meta-analytic techniques to estimate the separate effects of the starting age, program duration, and persistence of impacts of early childhood education programs on children’s cognitive and achievement outcomes. It concentrates on studies published before the wide scale… more →
Air Filters, Pollution and Student Achievement
This paper identifies the achievement impact of installing air filters in classrooms for the first time. To do so, I leverage a unique setting arising from the largest gas leak in United States history, whereby the offending gas company installed air filters in every classroom, office and common… more →
Untangling the Evidence on Preschool Effectiveness: Insights for Policymakers
Research showing that high-quality preschool benefits children’s early learning and later life outcomes has led to increased state engagement in public preschool. However, mixed results from evaluations of two programs—Tennessee’s Voluntary Pre-K program and Head Start—have left many… more →
Community Schools as an Effective School Improvement Strategy: A Review of the Evidence
This report synthesizes the research evidence about the impact of community schools on student and school outcomes. Its aim is to support and inform school, community, district, and state leaders as they consider, propose, or implement community schools as a strategy for providing equitable,… 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 →
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 →
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 →
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 →
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 →
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 →
Strengthening STEM Instruction in Schools: Learning from Research
More than half of U.S. children fail to meet proficiency standards in mathematics and science in fourth grade. Teacher professional development and curriculum improvement are two of the primary levers that school leaders and policymakers use to improve children’s science, technology, engineering… 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 →
Trends in Children’s Academic Skills at School Entry: 2010 to 2017
Students’ level of academic skills at school entry are a strong predictor of later academic success, and focusing on improving these skills during the preschool years has been a priority during the past ten years. Evidence from two prior nationally representative studies indicated that incoming… more →
STEM Instruction Improvement Programs Improve Student Outcomes
How should teachers spend their STEM-focused professional learning time? To answer this question, we analyzed a recent wave of rigorous new studies of STEM instructional improvement programs. We found that programs work best when focused on building knowledge teachers can use during instruction… more →
The Short- and Long-Run Impacts of Secondary School Absences
We provide novel evidence on the causal impacts of student absences in middle and high school on state test scores, course grades, and educational attainment using a rich administrative dataset that tracks the date and class period of each absence. We use two similar but distinct identification… more →
Effects of the Flipped Classroom: Evidence from a Randomized Trial
In a flipped classroom, an increasingly popular pedagogical model, students view a video lecture at home and work on exercises with the instructor during class time. Advocates of the flipped classroom claim the practice not only improves student achievement, but also ameliorates the achievement… more →
