Research & Service

Dr. Jinming Zhang's research focuses on theoretical and applied statistical issues involved in educational and psychological measurement, and his research interest includes multidimensional item response theory, dimensionality assessment techniques, large-scale assessments, generalizability theory, and test security. From 1996 to 2009 he was employed at the Educational Testing Service (ETS) where he was a senior research scientist in the Division of Research and Development. He had worked on various research and operational projects related to large-scale educational assessments, specifically, the National Assessment of Educational Progress (NAEP), at ETS. He successfully directed and co-directed statistical and psychometric analyses of many large-scale assessment projects such as the 1996 and 2005 national science, 2000 state science, 1998, 2002 and 2003 national and state reading, 2006 national civics, and 2008 national arts assessments.

Applied Regression Analysis Emphasis on educational research applications of regression with special emphasis placed on application and interpretation of techniques. Topics covered include rudimentary linear algebra, the general linear model, different coding schemes, regression diagnostics, and extensions to binary data and nested data structures. Same as PSYC 581.

Advanced Statistical Methods Advanced topics in analyses of variance and covariance, and principles of experimental design; brief introduction to multivariate analysis, including rudiments of matrix algebra.

Theories of Measurement I Provides a conceptual framework of classical test theory (e.g., true scores, error of measurement, composite measures) and alternatives to the classical model (e.g., generalizability theory, latent trait theory). Students will learn the techniques and theory of classical test theory and apply the methods to educational and psychological assessments. Topics covered include reliability, validity, generalizability, dichotomous Item Response Theory (IRT), test construction and design, item bias and fairness, Differential Item Functioning (DIF), scaling, linking, and equating. Same as PSYC 595.
