Stephen Roman teaches chemistry and physical science at Lee County High School in Sanford. Stephen earned his Ed. S. degree in science education from Rutgers University. His project, Modeling in Chemistry: The Development of Atomic Theory, seeks to transform instruction of atomic theory from a passive history lesson into an active process of evaluating evidence, models, and the explanations provided by these models. Stephen’s mentor is Dr. Maria Oliver-Hoyo, associate professor of chemistry at NC State University.
