The Design of Clustered Observational Studies in Education
Topics: MethodsTags: Assessment, EfficacyClustered observational studies (COSs) are a critical analytic tool for educational effectiveness research. We present a design framework for the development and critique of COSs. The framework is built on the counterfactual model for causal inference and promotes the concept of… more →
The learning curve: Revisiting the assumption of linear growth across the school year
Topics: Student LearningImportant educational policy decisions, like whether to shorten or extend the school year, often require accurate estimates of how much students learn during the year. Yet, related research relies on a mostly untested assumption: that growth in achievement is linear throughout the entire… more →
Does the Common Core Have a Common Effect?: An Exploration of Effects on Academically Vulnerable Students
Tags: Assessment, EquityPolicymakers have sought to increase the rigor of content standards since the 1990s. However, the literature examining the effects of reforms to content standards on student outcomes is still developing. This study examines the extent to which the Common Core State Content Standards (CC)… more →
Long-run Trends in the U.S. SES-Achievement Gap
Topics: Student LearningTags: Assessment, PovertyRising inequality in the United States has raised concerns about potentially widening gaps in educational achievement by socio-economic status (SES). Using assessments from LTT-NAEP, Main-NAEP, TIMSS, and PISA that are psychometrically linked over time, we trace trends in achievement for U.S.… more →
Testing, Teacher Turnover and the Distribution of Teachers Across Grades and Schools
Topics: Policy, Politics, and GovernanceTeacher turnover has adverse consequences for student achievement and imposes large financial costs for schools. Some have argued that high-stakes testing may lower teachers’ satisfaction with their jobs and could be a major contributor to teacher attrition. In this paper, we exploit changes in… more →
Can Camp Get You Into a Good Secondary School? A Field Experiment of Targeted Instruction in Kenya
Access to quality secondary schooling can be life-changing for students in developing contexts. In Kenya, entrance to such schools has historically been determined by performance on a high-stakes exam. Understandably then, preparation for this exam is a high priority for Kenyan families and… more →
Teacher Effects on Student Achievement and Height: A Cautionary Tale
Topics: MethodsTags: AssessmentEstimates of teacher “value-added” suggest teachers vary substantially in their ability to promote student learning. Prompted by this finding, many states and school districts have adopted value-added measures as indicators of teacher job performance. In this paper, we conduct a new test of the… more →
Ever Failed, Try Again, Succeed Better: Results from a Randomized Educational Intervention on Grit
Topics: Student Well-BeingWe show that grit, a skill that has been shown to be highly predictive of achievement, is malleable in childhood and can be fostered in the classroom environment. We evaluate a randomized educational intervention implemented in two independent elementary school samples. Outcomes are measured via… more →
Trends in Children’s Academic Skills at School Entry: 2010 to 2017
Topics: Student LearningStudents’ 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 →
Get Real! Inflation Adjustments of Education Finance Data
Tags: AssessmentUse of education finance data is ubiquitous. Yet, because the academic calendar circumscribes two calendar years, researchers have linked the Consumer Price Index to three different dates: the Fall, Spring and academic fiscal years. We demonstrate that linking the CPI to these different academic… more →
Ready or Not? California's Early Assessment Program and the Transition to College
In this paper we investigate the impact of a statewide program aimed at better aligning K-12 to higher education and improving college readiness. We replicate an earlier study focused on the effects of this program at one campus by employing detailed administrative data on the census of… more →
The Effects of Race to the Top School Turnaround in North Carolina
Topics: Policy, Politics, and GovernanceTags: Assessment, School reformFederal education policies gave political and financial support for state education agencies to turnaround low-performing schools on an unprecedented scale. North Carolina’s ambitious program turned around over half of all schools nationwide that underwent turnaround funded by Race to the Top.… more →
Horizontal Differentiation and the Policy Effect of Charter Schools
Topics: School ChoiceTags: Charter schools, AssessmentWhile school choice may enhance competition, incentives for public schools to raise productivity may be muted if public education is viewed as imperfectly substitutable with alternatives. This paper estimates the aggregate effect of charter school expansion on education quality while accounting… more →
Accountability-Driven School Reform: Are There Unintended Effects on Younger Children in Untested Grades?
Topics: Student LearningTest-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 →
Quasi-Experimental Evaluation of Alternative Sample Selection Corrections
Topics: MethodsTags: Assessment, Higher educationWe use a natural experiment to evaluate sample selection correction methods' performance. In 2007, Michigan began requiring that all students take a college entrance exam, increasing the exam-taking rate from 64 to 99%. We apply different selection correction methods, using different sets of… more →
Take Two! SAT Retaking and College Enrollment Gaps
Only half of SAT-takers retake the exam, with even lower retake rates among low income and underrepresented minority (URM) students. We exploit discontinuous jumps in retake probabilities at multiples of 100, driven by left-digit bias, to estimate retaking’s causal effects. Retaking… more →
School District Operational Spending and Student Outcomes: Evidence from Tax Elections in Seven States
Tags: School districts, AssessmentWe use close tax elections to estimate the impact of school district funding increases on operational spending and student outcomes across seven states. Districts with passing levies directed new revenue toward support services and instructor salaries but did not increase teacher staffing levels… more →
Interpreting Effect Sizes of Education Interventions
Topics: MethodsTags: Assessment, EfficacyResearchers commonly interpret effect sizes by applying benchmarks proposed by Cohen over a half century ago. However, effects that are small by Cohen’s standards are large relative to the impacts of most field-based interventions. These benchmarks also fail to consider important differences in… more →
