Public Opinion, Attitude Stability, and Education Policy
Do Americans hold a consistent set of opinions about their public schools and how to improve them? From 2013 to 2018, over 5,000 unique respondents participated in more than one consecutive iteration of the annual, nationally representative Education Next poll, offering an opportunity to examine… more →
Skills, Degrees and Labor Market Inequality
Over the past four decades, income inequality grew significantly between workers with bachelor’s degrees and those with high school diplomas (often called “unskilled”). Rather than being unskilled, we argue that these workers are STARs because they are skilled through alternative routes—namely… more →
Measuring Conversational Uptake: A Case Study on Student-Teacher Interactions
In conversation, uptake happens when a speaker builds on the contribution of their interlocutor by, for example, acknowledging, repeating or reformulating what they have said. In education, teachers' uptake of student contributions has been linked to higher student achievement. Yet measuring and… more →
Characterizing Cross-Site Variation in Local Average Treatment Effects in Multisite Regression Discontinuity Design Contexts with an Application to Massachusetts High School Exit Exam
In multisite experiments, we can quantify treatment effect variation with the cross-site treatment effect variance. However, there is no standard method for estimating cross-site treatment effect variance in multisite regression discontinuity designs (RDD). This research rectifies this gap in… more →
The Unintended Effects of the Common Core State Standards on Non-Targeted Subjects
From 2010 onwards, most US states have aligned their education standards by adopting the Common Core State Standards (CCSS) for math and English Language Arts. The CCSS did not target other subjects such as science and social studies. We estimate spillovers of the CCSS on student achievement in… more →
Using Implementation Fidelity to Aid in Interpreting Program Impacts: A Brief Review
Poor program implementation constitutes one explanation for null results in trials of educational interventions. For this reason, researchers often collect data about implementation fidelity when conducting such trials. In this article, we document whether and how researchers report and measure… more →
The Kids on the Bus: The Academic Consequences of Diversity-Driven School Reassignments
Many public school diversity efforts rely on reassigning students from one school to another. While opponents of such efforts articulate concerns about the consequences of reassignments for students’ educational experiences, little evidence exists regarding these effects, particularly in… more →
Health Equity, Schooling Hesitancy, and the Social Determinants of Learning
At least 25 million K-12 students in the U.S.—disproportionately children of color from low-income families—have been physically out of school for a full year due to the COVID-19 pandemic. These children are at risk of significant academic, social, mental, and physical harm now and in the long… more →
The Populist-Burkean Dimension in U.S. Public Opinion
Scholars differ as to whether populist beliefs are a discourse or an ideology resembling conservatism or liberalism. Research has shown that a belief in popular sovereignty and a distrust of public officials are core components of populism. Its antithesis is defined as Burke’s claim that… more →
Achievement Gaps in the Wake of COVID-19
A survey targeting education researchers conducted in November, 2020 provides both short- and longer-term predictions of how much achievement gaps between low- and high-income students in U.S elementary schools will change as a result of COVID-related disruptions to schooling and family life.… more →
Effectiveness Research for Teacher Education
Despite calls for more evidence regarding the effectiveness of teacher education practices, causal research in the field remains rare. One reason is that we lack designs and measurement approaches that appropriately meet the challenges of causal inference in the context of teacher education… more →
Using Behavioral Insights to Improve School Administrative Communications: The Case of Truancy Notifications
Many states mandate districts or schools notify parents when students have missed multiple unexcused days of school. We report a randomized experiment (N = 131,312) evaluating the impact of sending parents truancy notifications modified to target behavioral barriers that can… more →
Apart but Connected: Online Tutoring and Student Outcomes during the COVID-19 Pandemic
In response to the COVID-19 outbreak, the governments of most countries ordered the closure of schools, potentially exacerbating existing learning gaps. This paper evaluates the effectiveness of an intervention implemented in Italian middle schools that provides free individual tutoring online… more →
Is Engaging Online Learning Possible? A Study of an Innovative National Virtual Summer Program
We study an early effort amid the Covid-19 pandemic to develop new approaches to virtually serving students, supporting teachers, and promoting equity. This five-week, largely synchronous, summer program served 11,769 rising 4th-9thgraders. “Mentor teachers” provided PD and videos of themselves… more →
Learning Lessons from Instruction: Descriptive Results from an Observational Study of Urban Elementary Classrooms
Background:
For nearly three decades, policy-makers and researchers in the United States have promoted more intellectually rigorous standards for mathematics teaching and learning. Yet, to date, we have limited descriptive evidence on the extent to which reform-oriented… more →Education Leaders’ Knowledge of Causal Research Design: A Measurement Challenge
Federal policy has both incentivized and supported better use of research evidence by educational leaders. However, the extent to which these leaders are well-positioned to understand foundational principles from research design and statistics, including those that underlie the What Works… more →
How Can Released State Test Items Support Interim Assessment Purposes in an Educational Crisis?
State testing programs regularly release previously administered test items to the public. We provide an open-source recipe for state, district, and school assessment coordinators to combine these items flexibly to produce scores linked to established state score scales. These would enable… more →
Immigrant Integration in the United States: The Role of Adult English Language Training
While current debates center on whether and how to admit immigrants to the United States, little attention has been paid to interventions designed to help immigrants integrate after they arrive. Public adult education programs are the primary policy lever for building the language skills of the… more →
Test-Based Accountability and the Effectiveness of School Finance Reforms
A recent literature provides new evidence that school resources are important for student outcomes. In this paper, we show that school finance reform-induced increases in student performance are driven by those states that had test-based accountability policies in place at the time. By… more →
Improving Low-Performing Schools: A Meta-Analysis of Impact Evaluation Studies
The public narrative surrounding efforts to improve low-performing K-12 schools in the U.S. has been notably gloomy. Observers argue that either nothing works or we don’t know what works. At the same time, the federal government is asking localities to implement evidence-based interventions. But… more →
