Dr. Ying “Alison” Cheng currently directs the Learning Analytics and Measurement in Behavioral Sciences (LAMBS) lab. Her research focuses on two areas: 1) Psychological and educational measurement; 2) Learning analytics.

In the first area, she is interested in theoretical development and applications of item response theory (IRT), including computerized adaptive testing (CAT), test equity across different ethnicity/gender groups (formally known as different item functioning or DIF), classification accuracy and consistency with licensure/certification of state graduation exams, and cognitive diagnostic models and their applications to CAT.

In the second area, she is interested in applying data mining techniques to large-scale, multi-modal learning data, e.g., process data collected from human-computer interactions.
