Overview
Biography
J.R. Lockwood is a senior statistician at the RAND Corporation, where he has worked on a variety of quantitative analyses of education, environmental, and health policy problems. Lockwood specializes in longitudinal modeling of student achievement, value-added models for estimating teacher effects, relationships between teaching practices and student achievement, and experimental and quasi-experimental methods in educational evaluation. His methodological areas of expertise include hierarchical, longitudinal, and random effects modeling; Bayesian methods; statistical computing; and regression discontinuity analysis. His extensive work with value-added modeling for estimating teacher effects includes several papers on statistical and computational methods and the development of software for implementing complex models with large datasets. Lockwood has led two Institute of Education Sciences projects to develop enhanced models for estimating teacher effects and is currently conducting two randomized trials on teacher pay for performance. Lockwood received his Ph.D. in statistics from Carnegie Mellon University.
