Dr. Henson’s primary focus of research is diagnostic classification models (also known as cognitive diagnosis models).  These models score a test in a way that provides a mastery profile that specifies what a student has mastered or not mastered as opposed to providing a single score. The goal is to provide detailed information that may allow for tailored lesson plans specific to a student. Dr. Henson has also expanded his research to Hierarchical Linear models (also known as Mixed Models) and their application. In addition, Dr. Henson serves as the director of graduate studies and continues to explore new ways incorporating technology in to his classes.
