Chiu, Chia-Yi (cc5010)

PhD, Quantitative Methodology, Measurement, and Evaluation program, Educational Psychology, University of Illinois at Urbana-Champaign

MS, Statistics, University of Illinois at Urbana-Champaign

MA, Mathematics in Teaching, University of Northern Colorado

BS, Mathematics, National Taiwan Normal University

While research on “big data” in educational measurement is thriving, Professor Chiu focused on “small data.” She is well recognized for her award-winning research on the advancement of educational assessments for the classroom that permit monitoring teaching and learning in real-time. Dr. Chiu has made groundbreaking contributions to the field of nonparametric cognitive diagnosis in developing its theory and implementing innovative algorithms for STEM assessments.
