In this study, we estimated the relationship between two popular measures of teacher effectiveness--teachers' value-added model (VAM) estimates, represented in this study via median growth percentiles (MGPs), and teachers' observational scores, derived from the TAP System for Teacher and Student Advancement. We examined the relationship between…

Until recently, legal challenges to using value-added models (VAMs) throughout the United States (US) for high-stakes teacher evaluative decisions (e.g., merit pay, tenure, and termination) were unsuccessful, especially in the state of Florida. Hence, prior and still, multiple teachers throughout Florida have been terminated or involuntarily…

The purpose of this study is to critically evaluate value-added accountability measures currently enacted in the United States at the federal and state levels to assess teacher preparation programme (TPP) effectiveness. We draw on Newton and Shaw's framework for the evaluation of testing policy to evaluate the technical quality and social…

Since the adoption of teacher evaluation systems that rely, at least in part, on controversial student achievement measures, little research has been conducted that focuses on stakeholders' perceptions of systems in practice, specifically school principals. This study was conducted in a large urban school district to better understand principals'…

In this study, we investigated the factor structure underlying the TAP System for Teacher and Student Advancement used across the nation for increased teacher-level accountability purposes. We found evidence of poor fit based on the factor structure posited and found large correlations among dimensions, suggesting one-to-two factors with one…

Despite the prevalence of student learning objectives (SLOs) in teacher evaluation systems throughout the United States, research on the validity of student and teacher SLO scores used for high-stakes decisions is lacking. For this reason, this dissertation is comprised of two chapters that examine student and teacher-level SLO performance data…

This quantitative study investigated the relationship between teacher dispositions, subject content knowledge, pedagogical content knowledge, and reasons that school principals recommend non-renewal of teachers' contracts. Nearly 2,000 school principals in 13 states completed an emailed survey. In deciding whether to non-renew a teacher contract,…

Teacher evaluation is at the center of current education policy reform. Most evaluation systems rely at least in part on principals' assessments of teachers, and their discretionary judgments carry substantial weight. However, we know relatively little about what they value when determining evaluations and high stakes personnel decisions. The…

What is effective teaching? It is not enough to say "I know it when I see it"--not when we are expecting so much more from students and teachers than in the past. To help teachers achieve greater success with their students we need new and better ways to identify and develop effective teaching. The Measures of Effective Teaching (MET)…

Teacher preparation programs (TPPs) are where prospective teachers gain a foundation of knowledge about pedagogy and subject matter, as well as early exposure to practical classroom experience. Although competence in teaching, as in all professions, is shaped significantly by on-the-job experiences and continuous learning, the programs that…
