Increasing job demands and continuing struggles to improve teacher evaluation practice raise the question of how peers might assist principals with teacher evaluation. Using a robust international sample (TALIS2013) of 36,411 teachers from 2,759 schools in 11 countries, we tested the hypothesis that teacher-led evaluation practices are associated…

Teaching observation protocols serve purposes beyond research, such as providing formative feedback for teachers' growth in their practice. Such observation tool usage requires different approaches for validation. For this reason, we developed the formative teaching evaluation framework adapted from the student-assessment literature. We used this…

The aim of teaching observations and post observation feedback in higher education is to support teachers to reflect on and improve their teaching. Yet, our understanding of tutors' (observers') and teachers' (observees') capacities for capitalising on these feedback opportunities is limited and there is little empirically derived advice for…

With the aim to provide teachers with more specific, frequent, and actionable feedback about their teaching, we explore how Large Language Models (LLMs) can be used to estimate "Instructional Support" domain scores of the CLassroom Assessment Scoring System (CLASS), a widely used observation protocol. We design a machine learning…

Several state policies link high-stakes consequences to teacher evaluations, which tend to be heavily weighted by observation scores. However, research has only recently investigated the validity of these scores in field settings. This study examines the sensitivity of teacher observation scores to the number of observations assigned by state…

This paper reports the main findings of a study that sought to understand how teachers and department heads perceived and experienced the implementation of a classroom observation system in a teacher evaluation context. The data was collected through a teacher and department head survey and interviews with department heads who were responsible for…

Education reform legislation has led to an upwelling of mandatory teacher evaluation for all elementary, middle school, and high school educators, including those who teach special education. While this reform effort aimed to improve overall teacher effectiveness and student learning outcomes, the teacher evaluation for special education is a…

The notion that teacher quality impacts student achievement is widely accepted. How to best define, measure, and improve teacher quality continues to be debated by teacher unions and state legislators. Teacher evaluation studies have focused on isolated elements of the system. The purpose of this quantitative study was to examine the current…

Districts nationwide have increased the frequency of teacher evaluations. Yet, we know little about the role of evaluator feedback for teacher improvement. Using unique classroom observation-level data, we use evaluator ratings and teacher self-assessments of teacher performance to rigorously examine (positive and negative) feedback valence from…

Teacher observations are being used for high-stakes purposes in states across the country, and administrators often serve as raters in teacher evaluation systems. This paper examines how the cognitive aspects of administrators' use of an observation instrument, a modified version of Charlotte Danielson's Framework for Teaching, interact with the…

Over the past five years, policymakers have shown a renewed interest in using teacher evaluation as a lever for increasing the quality of the teacher labor market. As such, states have been spurred by federal policies such as Race to the Top and influential foundations such as the Bill & Melinda Gates Foundation to use a more reliable, more…

Responding to an Illinois law that took effect in 2010, the Performance Evaluation Reform Act (PERA), Chicago Public Schools (CPS) created and implemented the REACH (Recognizing Educators Advancing Chicago's Students) educator evaluation and support system. REACH was piloted in 2012-13. It is still being implemented as of the 2019-20 school year,…

The Scylla and Charybdis in this discussion of teacher evaluation are standardized achievement test data on the one hand, and classroom observational systems on the other. These are the two most common methods used to judge teachers' competency. Both have serious flaws: the former primarily with validity, the latter primarily with reliability. At…

Results from a sample of 1,013 Georgia principals who rated 12,617 teachers are used to compare holistic and analytic principal judgments with indicators of student growth central to the state's teacher evaluation system. Holistic principal judgments were compared to mean student growth percentiles (MGPs) and analytic judgments from a formal…

Research on the evaluation of the professional knowledge of mathematics teachers (comprising for example mathematical content knowledge, mathematics pedagogical content knowledge and general pedagogical knowledge) has become prominent in the last decade; however, the development of video-based assessment approaches is a more recent topic. This…
