As a Professor and former chair of the Department of Communication, University of Mount Union, William Coleman developed and taught courses that encouraged students to cross cultural borders. African American Rhetoric, Intercultural Communication, Peace Communication, American Indian Rhetoric, Social Movements, and Race & Class in American Society were a few.
In his academic career, Coleman continually crossed borders. Sabbaticals were taken to Germany to study the Green Party, Mexico City and Arizona and New Mexico for North American Indian study, and the Tesuque Pueblo (Santa Fe, New Mexico) to study American Indian culture. Coleman lectured at Shanghai University of Finance and Economics, Peking University, Hefei University (Anhui Province) in the Peoples Republic of China, and Baika University in Osaka, Japan. He led student trips to the Tesuque Pueblo Reservation and Peking University in Beijing and travelled throughout Europe, China, Japan, Penang, Hong Kong, Singapore, and Mexico City.
He has worked closely with Hiroshima Jogakuin University and High School, and the Hiroshima Peace Culture Foundation and was a faculty advisor to Mount Union’s Association of International Students for 15 years.
He is currently Professor Emeritus and Adjunct Professor, Department of Communication, University of Mount Union.
