SIG Officers

Chair:  Jue Wang, Ph.D., is an assistant professor in the Research, Measurement & Evaluation Program at the University of Miami. She received her Ph.D. from the University of Georgia (UGA) in Quantitative Methodology (QM) under the Department of Educational Psychology. She has also obtained a M.S. degree in Statistics at UGA. Jue has developed her program of research based on Rasch measurement theory. Her research focuses on examining rating quality and rater effects in rater-mediated assessments using Rasch measurement models, unfolding models, and multilevel Rasch models. Jue has just completed a book with Professor George Engelhard entitled “Rasch models for solving measurement problems: Invariant measurement in the social sciences” that is currently in press by Sage as part of their Quantitative Applications in the Social Sciences (QASS) series. Meanwhile, she and Professor George Engelhard have developed a digital ITEMS module introducing the Rasch measurement theory. Jue has served as an editorial assistant for the Journal of Educational Measurement from 2016 to 2018. She has reviewed for leading journals including Applied Psychological Measurement, Journal of Educational and Behavioral Statistics, International Journal of Testing, Language Testing, Assessing Writing, and TESOL Quarterly.

Treasurer:  Dandan Liao, Ph.D., is a psychometrician at Cambium Assessment, Inc., formerly AIR Assessment. Under the supervision of Dr. Hong Jiao, she obtained her Ph.D. and M.A. degrees in Measurement, Statistics, and Evaluation program from the University of Maryland. Before that, she received her bachelor’s degree in statistics from Beijing Normal University in China. Her research interests include standard and extended item response theory models, local dependency, and process data. Her work in the multigroup cross-classified Rasch model won her the Best Graduate Student Paper Award in the 18th International Objective Measurement Workshop in 2016. Built on the Rasch model, her dissertation focuses on the speed-accuracy-difficulty interaction in the joint modeling of responses and response times. As a psychometrician, she provides psychometric support for the Next Generation Science Standards Assessments, which utilize the multigroup Rasch testlet model. She has developed methods for item fit, reliability, linking, and scoring in the multigroup Rasch testlet model. As the treasurer of the Rasch SIG, she hopes to contribute to the Rasch community by bringing in more research and application of the Rasch model. Contact: dandan.liao@cambiumassessment.com

Secretary:  Eli Jones, Ph.D., is an assistant professor in the Educational Psychology and Research department at the University of Memphis.  He received his Ph.D. from Brigham Young University (BYU) from the Educational Inquiry, Measurement, and Evaluation department.  He has also served as a postdoctoral researcher for the Network for Educator Effectiveness at the University of Missouri, as an assistant professor of research at Columbus State University (Georgia), and as a second grade public school teacher.  His area of research is currently focused on the measurement properties of rater-mediated assessments in education.  Specifically, his research focuses on the application of many-facet Rasch models to educator evaluation (including teacher evaluation, principal evaluation, and evaluation of teacher candidates).  His research has explored the psychometric properties of observational instruments, as well as the implications of sparse rating designs on model-data fit, rater error, and stability of rater severity estimates.

Past SIG officers (2018-2020)

Chair:        Hong Jiao, Ph.D.                      University of Maryland

Treasurer:   Matthew Schulz, Ph.D.           Smarter Balanced

Secretary:  Cari Herrmann Abell, Ph.D.    BSCS Science Learning 

Program Co-Chairs

The co-chairs assign reviews to volunteer reviewers, use reviews to make acceptance/rejection decisions, and put together the sessions for the SIG. We solicit nominations for one Program Co-Chair every spring. This is a two-year position.  There are two co-chairs each year that are staggered in rotation so that we always have someone with a year experience and someone who just started.

Courtney Donovan, PhD, is a Clinical Assistant Professor at the University of Colorado Denver where she teaches graduate level research methods, qualitative analysis, statistical modeling, and measurement techniques.  She is also the Director of the School of Education and Human Development’s Faculty Research Center where she aids, consults on, and promotes faculty’s research. As a former middle school STEM teacher, Courtney’s research interests include working in the "research to practice" gap in education, developing & validating measures in social sciences, and statistical modeling with datasets encouraging societal change.

Manqian Liao, Ph.D., serves as the chair of the Rasch SIG since 2020. She is a psychometrician at Duolingo. She received her doctoral degree in measurement, statistics and evaluation at the University of Maryland, College Park. She is dedicated to addressing the applied issues in educational measurement, especially the fairness and validity issues, by conducting quantitative research. She has also conducted research on cognitive diagnostic modeling with the aim to identify students’ strengths and weaknesses among a series of cognitive attributes.
