Teacher Evaluation Policies in the United States: Implementation and Impact on Constructivist Instruction Available to Purchase

Purpose – The author examines the implementation and characteristics of teacher evaluation and explores their associations with improvement in teachers’ practice of constructivist instruction.Methodology – This quantitative study uses statewide longitudinal Teachers’ Opportunity to Learn survey data collected in 2009 and 2010 from middle school mathematics teachers in Missouri and estimates a series of value-added models with two-level Hierarchical Linear Modeling.Findings – Teachers in this study were mainly evaluated by principals who conducted classroom observations and held face-to-face meetings to evaluate teaching practice and professional development activities. The study provides empirical evidence and support for the use of multiple evaluators with multiple evaluation data and outcomes in teacher evaluation. Additionally, it highlights the potential benefits of focusing on teachers’ instructional data instead of student achievement in teacher evaluation in order to improve their teaching practice.Research limitations – This study focused on middle school mathematics teachers in a single state in the United States. Whether these findings can be generalized to teachers of other subject areas or grades, or to states with different policy contexts, or to countries with country-specific structural, cultural, and social differences is unknown.Value – This study is the first effort to systematically examine teacher evaluation practices across a single state and provide empirical evidence on the relationships between the implementation characteristics of teacher evaluation and improvement in teachers’ instructional practice. Findings of this study provide school, district, state, federal, and international policymakers and administrators with important, up-to-date information on teacher evaluation at the middle-school level in the United States.
