Clarifies the primary questions raised by the use of value-added models (VAM) for measuring teacher effects, reviews the most important recent applications of VAM, and discusses statistical and measurement issues associated with VAM. Does value-added modeling (VAM) demonstrate the importance of teachers to student outcomes? The authors clarify the primary questions raised by VAM for measuring teacher effects, review the most important recent applications of VAM, and discuss a variety of statistical and measurement issues that might affect the validity of VAM inferences. The authors identify numerous possible sources of error and bias in teacher effects and recommend a number of steps for future research into these potential errors.

In our increasingly technological society, improving student performance in mathematics and science has become a challenge. This study investigates the relationship between student achievement in mathematics and science and the use of practices as funded by the National Science Foundation.
