There is a mistaken assumption in many social sciences that knowledge will automatically translate into action. Based on this assumption, textbooks for basic oral communication, a required course in many college campuses, attempt to ameliorate students' communicational behaviors by teaching them knowledge about communication: theories, concepts, and terms. Not only failing their attempt, these textbooks also estrange students by belaboring what is "common sense" in students' perception. However, in reality, numerous social problems are not because of a lack of knowledge, but because of a lack of action or a lack of practice of the knowledge. In an effort to shift attention from knowing communication to doing communication, Cases of Problematic Communication confronts its readers with realistic cases of problematic communication and offers questions to facilitate your reflection and communicational action. Promising to transform the students' learning from one of passive cognition to one of reflective action, this booklet can also serve as a resource for commercial textbooks for oral communication.
