The purpose of this study is to explore the correlation between state-recorded value- added (VA) scores and academic optimism (AO) scores, which measure teacher self-efficacy, trust, and academic emphasis. The sample for this study is 87 third through eighth grade Reading teachers, from fifty-five schools, in an urban school district in Ohio who…

Student peer effects are well documented; however, we know far less about peer effects among teachers. We hypothesize that a relatively effective teacher can positively affect the performance of his or her peers, whereas a relatively ineffective teacher may negatively affect the performance of other teachers with whom he or she works closely.…

Educational leaders are struggling with the issue of academic reform as it pertains to accountability for student achievement. With increasing pressures to improve student achievement, many states have adopted value-added measures to monitor student growth and teacher effectiveness. This study undertook a quantitative approach to examine the…

Teacher value-added measures (VAM) are designed to provide information regarding teachers' causal impact on the academic growth of students while controlling for exogenous variables. While some researchers contend VAMs successfully and authentically measure teacher causality on learning, others suggest VAMs cannot adequately control for exogenous…

Student peer effects are well documented. We know far less, however, about peer effects among teachers. We hypothesize that a relatively effective teacher may positively affect the performance of their peers, while a relatively ineffective teacher may negatively impact the performance of other teachers with whom they work closely. Utilizing a…

The purpose of this study was to investigate the relationship between the TVAAS growth score given by the Tennessee Department of Education and the overall Tennessee Educator Assessment Model (TEAM) observation rating for teachers in grades 3 through 8. The participating county public school system for this study is located in Northeast Tennessee.…

While most educators assume that not all students try their best on achievement tests, no current research examines if behaviors associated with low test effort, like rapidly guessing on test items, affect teacher value-added estimates. In this article, we examined the prevalence of rapid guessing to determine if this behavior varied by grade,…

We use panel data in Washington State to study the extent to which teacher assignments between fourth and eighth grade explain gaps between advantaged and disadvantaged students--as defined by underrepresented minority status (URM) and eligibility for free or reduced price lunch (FRL)--in their eighth grade math test scores and high school course…

Value-added modeling (VAM), one class of statistical models used to estimate individual teacher's or school's contribution to student achievement based on student test score growth between consecutive years, has become increasingly popular in the last decades. Despite the increasing popularity of VAM, many researchers are concerned about the…

This study advances our understanding of the relationships among the different elements of a teacher evaluation model and its usefulness in predicting student learning. Important questions arise about teacher evaluation systems, including (a) the magnitude of correlations among the sources of evidence used for identifying teacher effectiveness and…

High-quality measures of instructional practice are essential for research and evaluation of innovative instructional policies and programs, as well as for providing feedback to teachers and administrators. In this study, the authors examined whether using anchoring vignettes in web-based surveys improved the validity of teachers' self-assessments…

In this report, the authors describe the value-added models used as part of teacher evaluation systems in the District of Columbia Public Schools (DCPS) and in eligible DC charter schools participating in Race to the Top. They estimated (1) teacher effectiveness in DCPS and eligible DC charter schools during the 2011-2012 school year; and (2)…
