Professor Chang came to Purdue in August 2018. Prior to joining Purdue, he worked at the University of Illinois at Urbana-Champaign (UIUC) and held professorships in Educational Psychology, Psychology and Statistics. Professor Chang has focused his research primarily on methodological developments to support testing and assessment. Since August 2018, he has been devoting his effort to build assessment tools to help teaching and learning. He emphasized in a recent publication: “Modern theories in measurement are rapidly transforming testing from unaccommodating measures into informative tools that can be used to address various challenges in today’s teaching and learning.” His most current research projects include developing AI-powered diagnostic tools to improve classroom assessment in large college gateway courses, and also developing personalized adaptive assessment to support individualized learning.
