Classroom observation is an important component of teacher evaluation systems. Most states are implementing systems that assign a composite score to each teacher based on weights assigned to several different measures. Policy discussions often address this weighting, with many states adopting formulas with high weights for the summative scores…

Efficacy studies of educational programs often involve mediator analyses aimed at testing empirically appropriate theories of action. In particular, in the studies of professional development programs, the intervention targets primarily teachers' pedagogical skills and content knowledge, while the ultimate outcome is the student achievement…

NCLB waiver requirements have led to development of teacher evaluation systems, in which student growth is a significant component. Recent empirical research has been focusing on metrics of student growth--value-added scores in particular--and their relationship to other metrics. An extensive set of recent teacher-evaluation studies conducted by…

Efficacy studies of educational programs often involve mediator analyses aimed at testing empirically appropriate theories of action. In particular, in the studies of professional teacher development programs, the intervention targets presumably teacher performance while the ultimate outcome is the student achievement measured by a standardized…

The Regional Educational Laboratory Southwest Educator Effectiveness Research Alliance expressed interest in investigating annual teacher mobility in Texas. This resulting study, using data from the 2011/12-2015/16 school years, first asked how large teacher mobility was and how much of that movement was between schools in the same district, how…

Empirical Education Inc. conducted a quasi-experiment investigating the impact of the Alabama Math, Science, Technology Initiative (AMSTI) training. The study compared classes of fully-trained AMSTI teachers to classes taught by teachers with no AMSTI training within the same schools. The outcome measure was the ACT Aspire in math, science, and…

The motivation for this paper is the authors' recent work on several randomized control trials in which they found the primary result, which averaged across subgroups or sites, to be moderated by demographic or site characteristics. They are led to examine a distinction that the Institute of Education Sciences (IES) makes between "confirmatory"…

In October 2010, WestEd's Strategic Literacy Initiative (SLI) won an i3 "Validation" grant to scale up and validate the Reading Apprenticeship (RA) model in three core secondary content area classes: U.S. history, biology, and English language arts. SLI's proposal stated two goals. Goal 1: To transform academic literacy teaching and…

Federal initiatives and other research have led states across the nation to sharpen their focus on teacher evaluation in recent years. In 2009 a seminal report, "The Widget Effect," from The New Teacher Project revealed that in districts using a binary rating system to evaluate teachers, less than 1 percent of teachers received an…

The purpose of the current work is to apply several main principles of the causal explanatory approach for establishing external validity to the experimental arena. By spanning the paradigm of the experimental approach and the school of program evaluation founded by Lee Cronbach and colleagues, the authors address the question of how research…

This paper reports findings from a multi-year study of the scale-up of Reading Apprenticeship (RA), an approach to improve academic literacy by helping teachers provide the support students need to be successful readers in the content areas. WestEd's Strategic Literacy Initiative (SLI), began developing the program in 1995 and has since reached…

This study explored the relationships among the components of the Arizona Department of Education's new teacher evaluation model, with a particular focus on the extent to which ratings from the state model's teacher observation instrument differentiated higher and lower performance. The study used teacher-level evaluation data collected by the…

Teacher evaluation is currently a major policy issue at all levels of the K-12 system driven in large part by current US Department of Education requirements. The main objective of this study is to explore the patterns of relationship between observational scores and value-added measures of teacher performance in math classrooms and the variation…
