Local education agencies (LEAs) continue to use value-added models (VAMs) for teacher evaluation policies and purposes, often with consequences attached. Although the Every Student Succeeds Act (ESSA) provides more flexibility to LEAs, few have discontinued VAM use, suggesting they interpret VAMs as a valid measure of teacher effectiveness. In…

Contemporary teacher evaluation policies are built upon multiple-measure systems including, primarily, teacher-level value-added and observational estimates. However, researchers have not yet investigated how using these indicators to evaluate teachers might distort validity, especially when one indicator seemingly trumps, or is trusted over the…

Contemporary teacher evaluation systems are built upon multiple measures including, primarily, teacher-level value-added and observational estimates. While researchers have conducted examinations of these systems and indicators, researchers have not investigated how using these systems might distort the validity of the inferences being drawn,…

Despite the concerns regarding value-added models (VAMs), advocates hold strong to VAMs' theoretical strengths and potentials, while adopting a set of agreed-upon albeit "heroic" set of assumptions, without research in support. These assumptions transcend promotional, policy, media, and research-based pieces, but they have never been…

Recognizing the limitations of the existing frameworks and models applied to estimate the learning loss caused by COVID-19 across the world by different studies, and the urgent need for estimating such loss at the different education levels, this paper, employs the Education Value Chain Analysis ( EVCA) approach as a new paradigm, attempts to…

Papay (2011) noticed that teacher value-added measures (VAMs) from a statistical model using the most common pre/post testing timeframe--current-year spring relative to previous spring (SS)--are essentially unrelated to those same teachers' VAMs when instead using next-fall relative to current-fall (FF). This is concerning since this choice--made…

The Ohio Teacher Evaluation System (OTES) was created in response to the 2009 House Bill 1 mandate requiring the development of a state teacher performance assessment. This study examined K-12 public school teachers' dispositions toward OTES after the first year of implementation. Data were collected from 142 teachers over a 4-week period in 2015…

Policymakers and school administrators have embraced value-added models of teacher effectiveness as tools for educational improvement. Teacher value-added estimates may be viewed as complicated scores of a certain kind. This suggests using a test validation model to examine their reliability and validity. Validation begins with an interpretive…

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…
