What Impacts Should We Expect from Tutoring at Scale? Exploring Meta-Analytic Generalizability
Topics: MethodsU.S. public schools are engaged in an unprecedented effort to expand tutoring in the wake of the pandemic. Broad-based support for scaling tutoring emerged, in part, because of the large effects on student achievement found in prior meta-analyses. We conduct an expanded meta-analysis of 282… more →
The Causes and Consequences of U.S. Teacher Strikes
Topics: Policy, Politics, and GovernanceThe U.S. has witnessed a resurgence of labor activism, with teachers at the forefront. We examine how teacher strikes affect compensation, working conditions, and productivity with an original dataset of 772 teacher strikes generating 48 million student days idle between 2007 and 2023. Using an… more →
The Scaling Dynamics and Causal Effects of a District-Operated Tutoring Program
Public school systems across the U.S. have made major investments in tutoring to support students’ academic recovery in the wake of the COVID-19 pandemic. We evaluate a large urban district’s efforts to design, implement, and scale a district-operated, standards-based tutoring program across… more →
The Effect of Student-Tutor Ratios: Experimental Evidence from a Pilot Online Math Tutoring Program
Topics: Student LearningTags: Tutoring, Mathematics educationBudget constraints and limited supplies of local tutors have caused many K-12 school districts to pivot from individual tutoring in-person toward small-group tutoring online to expand access to personalized instruction. We conduct a field experiment to explore the effect of increasing student-… more →
The Rise and Fall of the Teaching Profession: Prestige, Interest, Preparation, and Satisfaction over the Last Half Century
We examine the state of the U.S. K-12 teaching profession over the last half century by compiling nationally representative time-series data on four interrelated constructs: occupational prestige, interest among students, the number of individuals preparing for entry, and on-the-job satisfaction… more →
Time in School: A Conceptual Framework, Synthesis of the Causal Research, and Empirical Exploration
We examine the fundamental and complex role that time plays in the learning process. We begin by developing a conceptual framework to elucidate the multiple obstacles schools face in converting total time in school into active learning time. We then synthesize the causal research and document a… more →
Taking Teacher Evaluation to Scale: The Effect of State Reforms on Achievement and Attainment
Topics: Teacher and Leader DevelopmentTags: School reformFederal incentives and requirements under the Obama administration spurred states to adopt major reforms to their teacher evaluation systems. We examine the effects of these reforms on student achievement and attainment at a national scale by exploiting their staggered implementation across… more →
Grow Your Own: An Umbrella Term for Very Different Localized Teacher Pipeline Programs
Topics: Teacher and Leader Development“Grow Your Own” (GYO) programs have recently emerged as a promising approach to expand teacher supply, address localized teacher shortages, and diversify the profession. However, little is known about the scale and design of GYO programs, which recruit and support individuals from the local… more →
Teacher Shortages: A Framework for Understanding and Predicting Vacancies
We develop a unifying conceptual framework for understanding and predicting teacher shortages at the state, region, district, and school levels. We then generate and test hypotheses about geographic and subject variation in teacher shortages using data on unfilled teaching positions in Tennessee… more →
Preferences, Inequities, and Incentives in the Substitute Teacher Labor Market
We examine the labor supply decisions of substitute teachers – a large, on-demand market with broad shortages and inequitable supply. In 2018, Chicago Public Schools implemented a targeted bonus program designed to reduce unfilled teacher absences in largely segregated Black… more →
What Happened to the K-12 Education Labor Market During COVID? The Acute Need for Better Data Systems
The COVID-19 pandemic upended the U.S. education system and the economy in ways that dramatically affected the jobs of K-12 educators. However, data limitations have led to considerable uncertainty and conflicting reports about the nature of staffing challenges in schools. We draw on education… more →
Second Time's the Charm? How Sustained Relationships from Repeat Student-Teacher Matches Build Academic and Behavioral Skills
Topics: Student LearningWe 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
Topics: Student LearningTags: Tutoring, Instructional technologyA 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 →
The Inequitable Effects of Teacher Layoffs: What We Know and Can Do
Economic downturns can cause major funding shortfalls for U.S. public schools, often forcing districts to make difficult budget cuts including teacher layoffs. In this brief, we synthesize the empirical literature on the widespread teacher layoffs caused by the Great Recession. Studies find that… more →
Local Supply, Temporal Dynamics, and Unrealized Potential in Teacher Hiring
We explore the dynamics of competitive search in the K-12 public education sector. Using data from Boston Public Schools, we document how teacher labor supply varies substantially by position types, schools, and the timing of job postings. We find that early-posted positions are more likely to… more →
Elevating Education in Politics: How Teacher Strikes Shape Congressional Election Campaigns
Topics: Policy, Politics, and GovernanceTags:Teacher strikes have gained national attention with the “#RedforEd” movement. Such strikes are polarizing events that could serve to elevate education as a political priority or cast education politics in a negative light. We investigate this empirically by collecting original panel data on U.S… more →
The Big Problem with Little Interruptions to Classroom Learning
Narrative accounts of classroom instruction suggest that external interruptions, such as intercom announcements and visits from staff, are a regular occurrence in U.S. public schools. We study the frequency, nature, and duration of external interruptions in the Providence Public School District… more →
School-based Mentoring Relationships and Human Capital Formation
Topics: Student LearningWe document a largely unrecognized pathway through which schools promote human capital development – by fostering informal mentoring relationships between students and school personnel. Using longitudinal data from a large, nationally representative sample of adolescents, we explore the… more →
Can Teacher Evaluation Systems Produce High-Quality Feedback? An Administrator Training Field Experiment
Topics: Teacher and Leader DevelopmentTags: Professional developmentA core motivation for the widespread teacher evaluation reforms of the last decade was the belief that these new systems would promote teacher development through high-quality feedback. We examine this theory by studying teachers’ perceptions of evaluation feedback in Boston Public Schools and… more →
Operator versus Partner: A Case Study of Blueprint School Network’s Model for School Turnaround
Numerous high-profile efforts have sought to “turn around” low-performing schools. Evidence on the effectiveness of school turnarounds, however, is mixed, and research offers little guidance on which models are more likely to succeed. We present a mixed-methods case study of turnaround efforts… more →
