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 →
Strengthening the Research Base that Informs STEM Instructional Improvement Efforts: A Meta-Analysis
We present results from a meta-analysis of 95 experimental and quasi-experimental preK-12 science, technology, engineering, and mathematics (STEM) professional development and curriculum programs, seeking to understand what content, activities and formats relate to stronger student outcomes.… more →
Engaging Teachers: Measuring the Impact of Teachers on Student Attendance in Secondary School
Teachers’ impact on student long-run success is only partially explained by their contributions to students’ short-run academic performance. For this study, we explore a second dimension of teacher effectiveness by creating measures of teachers’ contributions to student class-attendance. We find… more →
