Research topics include generalized latent variable modeling and its parameter estimation, with a focus on item response modeling.
Data complexity Dr. Cho has dealt with consists of (1) multiple manifest person categories such as a control group versus an experimental group in an experimental design, (2) multiple latent person categories (or mixtures or latent classes) such as a mastery group versus a non-mastery group in a cognitive test, (3) multiple manifest item groups that may lead to multidimensionality such as number operation, measurement, and representation item groups in a math test, (4) multiple manifest person groups such as schools where students are nested in a multilevel (or hierarchical) data structure, and (5) multiple time points such as pretest and posttest in intervention studies.
Dr. Cho has collaborated with researchers from a variety of disciplines including reading education, math education, special education, clinical psychology, cognitive psychology, and neuropsychology. She serves on the editorial boards of Journal of Educational Psychology, Behavior Research Methods, and International Journal of Testing.
