Teacher Evaluation, Ambitious Mathematics Instruction, and Mathematical Knowledge for Teaching: Evidence from Early Career Teachers
While teacher evaluation policies have been central to efforts to enhance teaching quality over the past decade, little is known about how teachers change their instructional practices in response to such policies. To address this question, this paper drew on classroom observation and survey… more →
First Impressions: The Case of Teacher Racial Bias
We study racial bias and the persistence of first impressions in the context of education. Teachers who begin their careers in classrooms with large black-white score gaps carry negative views into evaluations of future cohorts of black students. Our evidence is based on novel data on blind… more →
Bias in the Air: A Nationwide Exploration of Teachers' Implicit Racial Attitudes, Aggregate Bias, and Student Outcomes
Theory suggests that teachers’ implicit racial attitudes affect their students, but we lack large-scale evidence on US teachers’ implicit biases and their correlates. Using nationwide data from Project Implicit, we find that teachers’ implicit White/Black biases (as measured by the implicit… more →
Does Principal Professional Development Improve Schooling Outcomes? Evidence from Pennsylvania’s Inspired Leadership Induction Program
Principals shape the academic setting of schools. Yet, there is limited evidence on whether principal professional development improves schooling outcomes. Beginning in 2008-09, Pennsylvania’s Inspired Leadership (PIL) induction program required that newly hired principals complete targeted in-… more →
Diversifying the Teaching Profession: How to Recruit and Retain Teachers of Color
Research illustrates the importance of greater teacher diversity because of the substantial benefits teachers of color provide to all students, and to students of color in particular. Studies also show that policies must focus more effectively on retention of teachers of color, if diversity in… more →
Taking the Long View: State Efforts to Solve Teacher Shortages by Strengthening the Profession
Much is known about how to attract, develop, and retain a strong and stable teacher workforce, and states across the country are taking action to address their teacher shortages in ways that strengthen their overall teacher workforce.
Effective Teacher Professional Development
Teacher professional learning is of increasing interest as one way to support the increasingly complex skills students need to succeed in the 21st century. However, many teacher professional development initiatives appear ineffective in supporting changes in teacher practices and student… more →
Teacher Evaluation and Teacher Turnover, New Evidence from District of Columbia Public Schools
Few topics in education policy have received more attention than teacher turnover—and rightly so. The cost of losing a good teacher can be substantial and is born most directly by students. It is now widely recognized that teachers differ considerably in their ability to improve student outcomes… more →
Is Effective Teacher Evaluation Sustainable? Evidence from DCPS
Ten years ago, many policymakers viewed the reform of teacher evaluation as a highly promising mechanism to improve teacher effectiveness and student achievement. Recently, that enthusiasm has dimmed as the available evidence suggests the subsequent reforms had a mixed record of implementation… more →
Teacher evaluation for accountability and growth: Should policy treat them as complements or substitutes?
Teacher evaluation policies seek to improve student outcomes by increasing the effort and skill levels of current and future teachers. Current policy and most prior research treats teacher evaluation as balancing two aims: accountability and skill development. Proper teacher evaluation design… more →
The effects of higher-stakes teacher evaluation on office disciplinary referrals
Despite frequent political and policy debates, the effects of imposing accountability pressures on public school teachers are empirically indeterminate. In this paper, we study the effects of accountability in the context of teacher responses to student behavioral infractions in the aftermath of… more →
Improving Student Teachers’ Feelings of Preparedness to Teach Through Recruitment of Instructionally Effective and Experienced Cooperating Teachers: A Randomized Experiment
Prior work suggests that recent graduates from teacher education programs feel better prepared to teach and are more instructionally effective when they learned to teach with more instructionally effective cooperating teachers. However, we do not know if these relationships are causal. Even if they… more →
Teacher peer observation and student test scores: Evidence from a field experiment in English secondary schools
This paper reports improvements in teacher job performance, as measured by student test scores, resulting from a program of (zero-) low-stakes peer evaluation. Teachers working at the same school observed and scored each other’s teaching. Students in randomly-assigned treatment schools scored 0.… more →
Identifying Principal Improvement
Using statewide data from Tennessee over more than a decade, this paper estimates the job performance returns to principal experience as measured by student, teacher, and principal outcomes. I find that principals improve substantially over time, evidenced by higher student achievement, higher… more →
Developing Ambitious Mathematics Instruction Through Web-Based Coaching: A Randomized Field Trial
This paper describes and evaluates a web-based coaching program designed to support teachers in implementing Common Core-aligned math instruction. Web-based coaching programs can be operated at relatively lower costs, are scalable, and make it more feasible to pair teachers with coaches who have… more →
Teacher Skill Development: Evidence from Performance Ratings by Principals
We examine the dynamic nature of teacher skill development using panel data on principals’ subjective performance ratings of teachers. Past research on teacher productivity improvement has focused primarily on one important but narrow measure of performance: teachers’ value-added to student… more →
The Added Value of Latinx and Black Teachers for Latinx and Black Students: Implications for the Reauthorization of the Higher Education Act
A research synthesis points to the added-value—benefits to social and emotional development, as well as learning outcomes—for students of color taught by teachers of color. Given ongoing education debates, policymakers can use this evidence base to craft legislation aimed at… more →
Will Mentoring a Student Teacher Harm My Evaluation Scores? Effects of Serving as a Cooperating Teacher on Evaluation Metrics
Growing evidence suggests that preservice candidates receive better coaching and are more instructionally effective when they are mentored by more instructionally effective cooperating teachers (CTs). Yet, teacher education program leaders indicate it can be difficult to recruit instructionally… more →
Can Teacher Evaluation Systems Produce High-Quality Feedback? An Administrator Training Field Experiment
A 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 →
Policy Implementation, Principal Agency, and Strategic Action: Improving Teaching Effectiveness in New York City Middle Schools
Ten years ago, the reform of teacher evaluation was touted as a mechanism to improve teacher effectiveness. In response, virtually every state redesigned its teacher evaluation system. Recently, a growing narrative suggests these reforms failed and should be abandoned. This response may be… more →
