Student Learning
Computationally Identifying Funneling and Focusing Questions in Classroom Discourse
Responsive teaching is a highly effective strategy that promotes student learning. In math classrooms, teachers might funnel students towards a normative answer or focus students to reflect on their own thinking, deepening their understanding of math concepts. When teachers focus, they treat… more →
Beyond Teachers: Estimating Individual Guidance Counselors’ Effects on Educational Attainment
Counselors are a common school resource for students navigating complicated and con- sequential education choices. I estimate counselors’ causal effects using quasi-random assignment policies in Massachusetts. Counselors vary substantially in their effectiveness at increasing high school… more →
A Multi-State, Student-Level Analysis of the Effects of the Four-Day School Week on Student Achievement and Growth
Four-day school weeks are becoming increasingly common in the United States, but their effect on students’ achievement is not well-understood. The small body of existing research suggests the four-day schedule has relatively small, negative average effects (~-0.02 to -0.09 SD) on annual,… more →
The Long-Run Impacts of Universal Pre-K with Equilibrium Considerations
Since 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 →
U.S. Middle School Mathematics Instruction, 2016
In recent decades, U.S. education leaders have advocated for more intellectually ambitious mathematics instruction in classrooms. Evidence about whether more ambitious mathematics instruction has filtered into contemporary classrooms, however, is largely anecdotal. To address this issue, we… more →
How Much Do Early Teachers Matter?
We 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 →
Effectiveness of Tier 1 Content-Integrated Literacy Intervention on Early Elementary English Learners’ Reading Comprehension and Writing: Evidence from Randomized Controlled Trial
The current study replicated and extended the previous findings of content-integrated literacy intervention focusing on its effectiveness on first- and second-grade English learners’ (N = 1,314) reading comprehension, writing, vocabulary knowledge, and oral proficiency. Statistically significant… more →
Second Time's the Charm? How Sustained Relationships from Repeat Student-Teacher Matches Build Academic and Behavioral Skills
We examine the dynamic nature of student-teacher match quality by studying the effect of having a teacher for more than one year. Using data from Tennessee and panel methods, we find that having a repeat teacher improves achievement and decreases absences, truancy, and suspensions. These results… more →
Online Tutoring by College Volunteers: Experimental Evidence from a Pilot Program
A substantial body of experimental evidence demonstrates that in-person tutoring programs can have large impacts on K-12 student achievement. However, such programs typically are costly and constrained by a limited local supply of tutors. In partnership with CovEducation (CovEd), we conduct a… more →
An Investigation of Head Start Preschool Children’s Executive Function, Early Literacy, and Numeracy Learning in the Midst of the COVID-19 Pandemic
The COVID-19 pandemic’s impact on preschool children’s school readiness skills remains understudied. This research investigates Head Start preschool children’s early numeracy, literacy, and executive function outcomes during a pandemic-affected school year.
Understanding Newcomer English Learner Students’ English Language Development: Comparisons and Predictors
An important subgroup of English learner-classified (EL) students immigrate to the U.S., entering U.S. schools upon their arrival. Using growth models and statewide data, this study asks first, how newcomers’ English proficiency status and growth compare to those of non-newcomer EL students; and… more →
Learning-Mode Choice, Student Engagement, and Achievement Growth During the COVID-19 Pandemic
The COVID-19 pandemic initially resulted in an unanticipated and near-universal shift from in-person to virtual instruction in spring 2020. During the 2020-21 school year, schools began to re-open and families were faced with decisions regarding the instructional mode for their children. We… more →
Test Score Patterns Across Three COVID-19-impacted School Years
The COVID-19 pandemic has been a seismic and on-going disruption to K-12 schooling. Using test scores from 5.4 million U.S. students in grades 3-8, we tracked changes in math and reading achievement across the first two years of the pandemic. Average fall 2021 math test scores in grades 3-8 were… more →
Using Predicted Academic Performance to Identify At-Risk Students in Public Schools
Measures of student disadvantage—or risk—are critical components of equity-focused education policies. However, the risk measures used in contemporary policies have significant limitations, and despite continued advances in data infrastructure and analytic capacity, there has been little… more →
The Long-Run Educational Benefits of High-Achieving Classrooms
Despite the prevalence of school tracking, evidence on whether it improves student success is mixed. This paper studies how tracking within high school impacts high-achieving students’ short- and longer-term academic outcomes. Our setting is a large and selective Chinese high school, where first… more →
Do Refugee Students Affect the Academic Achievement of Peers? Evidence from a Large Urban School District
Policy debate on refugee resettlement focuses on perceived adverse effects on local communities, with sparse credible evidence to ascertain its impact. This paper examines whether attending school with refugees affects the academic outcomes of non-refugee students. Leveraging variation in the… more →
The Long-Term Effect of North Carolina’s Pre-Kindergarten Program is Larger in School Districts with Lower Rates of Growth in Academic Achievement
Prior research has found that public investments in North Carolina’s pre-kindergarten program—NC Pre-K—generated positive effects on student reading and math achievement through eighth grade (Bai et al., 2020). This study examined whether the effect of NC Pre-K funding exposure is moderated by… more →
The Uncertain Role of Educational Software in Remediating Student Learning: Regression discontinuity evidence from three local education agencies
Educators must balance the needs of students who start the school year behind grade level with their obligation to teach grade-appropriate content to all students. Educational software could help educators strike this balance by targeting content to students’ differing levels of mastery. Using a… more →
The Legacy of Covid-19 in Education
If school closures and social-distancing experiences during the Covid-19 pandemic impeded children’s skill development, they may leave a lasting legacy in human capital. To understand the pandemic’s effects on school children, this paper combines a review of the emerging international literature… more →
Spread Too Thin: The Effects of Teacher Specialization on Student Achievement
Although the majority of elementary school teachers are in self-contained classrooms and teach all major subjects, a growing number of teachers specialize in teaching fewer subjects to higher numbers of students. We use administrative data from Indiana to estimate the effect of teacher… more →
