Biography

Professor Chang's research has focused primarily on improving large scale assessments, specifically on issues emerged from the K-12 accountability testing. His research interests are broad, encompassing both theoretical development and applied methodologies, including Computerized Adaptive Testing, Differential Item Functioning, Cognitive Diagnosis, and asymptotic properties in IRT. Many of his manuscripts were published in top-tier journals, ranging from very theoretical, such as Annals of Statistics, to very applied, such as Journal of Educational Measurement. He is a past President of the Psychometric Society (2012-2013), Editor-in-Chief of Applied Psychological Measurement, and a Fellow of American Educational Research Association. He has been included on the "Incomplete List of Teachers Ranked Excellent by Their Students" for six consecutive years since 2008.

Courses

Theories of Measurement II Provides a conceptual framework of Item Response Theory (IRT) and its applications. Students will learn the techniques and theory of IRT and apply the methods to educational and psychological assessments. Topics covered include both dichotomous and polytomous IRT modelling, item structure and latent traits estimation, modeling and detecting Differential Item Functioning, linking and equating, computer adaptive testing, dimensionality testing, and cognitive diagnosis. Course Information: Same as PSYC 596. Prerequisite: EPSY 585 or PSYC 490.

Advanced Seminar in Educ Psyc Seminar in educational psychology; topics relate to the areas of specialization represented by the various divisions within the department. Course Information: Approved for both letter and S/U grading. May be repeated. Prerequisite: Consent of instructor required.
