Much of his research focuses on understanding and promoting educational change, both empirically through interviews, observations, and interventions with physics faculty and theoretically through analysis of change models and assumptions. Dr. Henderson has a number of publications and presentations related this work (see http://homepages.wmich.edu/~chenders/). His primary teaching assignments have been in the introductory calculus-based physics sequence, where, as part of the PhysTEC project, he has worked with his WMU colleagues to develop courses consistent with the results of educational research. He has taught high school physics and chemistry and is currently an officer in the Michigan AAPT section and chair of the national AAPT committee on research in physics education.
