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 →
The Impact of Targeted vs. General Education Investments: Evidence from Special Education and English Language Learners in Boston Charter Schools
Using novel variation in special education and English Language Learner classification from admissions lotteries, I find that students can achieve large academic gains without specialized services. Enrolling in a Boston charter school doubles the likelihood that students lose their special… more →
Complementarities between Early Educational Intervention and Later Educational Quality? A Systematic Review of the Sustaining Environments Hypothesis
The sustaining environments hypothesis refers to the popular idea, stemming from theories in developmental, cognitive, and educational psychology, that the long-term success of early educational interventions is contingent on the quality of the subsequent learning environment. Several studies… more →
English Learner Labeling: How English Learner Status Shapes Teacher Perceptions of Student Skills & the Moderating Role of Bilingual Instructional Settings
Prior research has shown that EL classification is consequential for students, however, less is known about how EL classification impacts students’ outcomes. In this study, we examine one hypothesized mechanism: teacher perceptions. Using nationally-representative data (ECLS-K:2011), we use… more →
The Effects of Special Education on the Academic Performance of Students with Learning Disabilities
In the forty plus years since passage of the Individuals with Disabilities Education Act (IDEA), special education has grown in the number of students and amount spent on services. Despite this growth, the academic performance of students with disabilities (SWDs) remains troubling low… more →
Teachers, Schools, and Pre-K Effect Persistence: An Examination of the Sustaining Environment Hypothesis
The sustaining environments thesis hypothesizes that PreK effects are more likely to persist into later grades if children experience high-quality learning environments in the years subsequent to PreK. This study tests this hypothesis using data from a statewide PreK randomized experiment in… more →
School's Out: The Role of Summers in Understanding Achievement Disparities
Summer learning loss (SLL) is a familiar and much-studied phenomenon, yet new concerns that measurement artifacts distorted canonical SLL findings create a need to revisit basic research on SLL. Though race/ethnicity and SES only account for about 4% of the variance in SLL, nearly all prior work… more →
How important are beliefs about gender differences in math ability? Transmission across generations and impacts on child outcomes
We study the transmission of beliefs about gender differences in math ability from adults to children and how this affects girls’ academic performance relative to boys. We exploit randomly assigned variation in the proportion of a child’s middle school classmates whose parents believe boys are… more →
Accountability-Driven School Reform: Are There Unintended Effects on Younger Children in Untested Grades?
Test-based accountability pressures have been shown to result in transferring less effective teachers into untested early grades and more effective teachers to tested grades. In this paper, we evaluate whether a state initiative to turnaround its lowest performing schools reproduced a similar… more →
The Play’s the Thing: Experimentally Examining the Social and Cognitive Effects of School Field Trips to Live Theater Performances
Field trips to see theater performances are a long-standing educational practice, however, there is little systematic evidence demonstrating educational benefits. This article describes the results of five random assignment experiments spanning two years where school groups were assigned by… more →
The Unwavering SES Achievement Gap: Trends in U.S. Student Performance
Concerns about the breadth of the U.S. income distribution and limited intergenerational mobility have led to a focus on educational achievement gaps by socio-economic status (SES). Uintertemporally linked assessments from NAEP, TIMSS, and PISA, we trace the achievement of U.S.
Heat and Learning
We demonstrate that heat inhibits learning and that school air-conditioning may mitigate this effect. Student fixed effects models using 10 million PSAT-retakers show hotter school days in years before the test reduce scores, with extreme heat being particularly damaging. Weekend and summer… more →
A Reanalysis of Impacts of the Tennessee Voluntary Prekindergarten Program
We present a reanalysis of the Tennessee Voluntary Prekindergarten Program (TNVPK), a state-funded program designed to promote the school readiness of 4-year-olds from low-income families. Oversubscribed programs used a lottery to randomly assign prospective enrollees a chance to… more →
Elusive Longer-Run Impacts of Head Start: Replications Within and Across Cohorts
Using an additional decade of CNLSY data, this study replicated and extended Deming’s (2009) evaluation of Head Start’s life-cycle skill formation impacts in three ways. Extending the measurement interval for Deming’s adulthood outcomes, we found no statistically significant… more →
Too little or too much? Actionable Advice in an Early-Childhood Text Messaging Experiment
Text-message based parenting programs have proven successful in improving parental engagement and preschoolers’ literacy development. The tested programs have provided a combination of (a) general information about important literacy skills, (b) actionable advice (i.e., specific examples of such… more →
