This teaching guide contains the materials required to teach a 6-week course in interpersonal communications that was developed for the workers of a Chicago medical center through a partnership involving the medical center, its employees, their union, and Northeastern Illinois University. Based on the student-centered philosophy of teaching, the curriculum includes six 2-hour lessons focused on developing basic speaking and listening skills and learning to distinguish between aggressive, assertive, and passive communication and behavioral styles. Topics, learner objectives, materials, handouts, and lesson plans developed for the course are integrated sequentially in the guide. Structured around a discussion of scenarios commonly leading to communication problems at work, the first lesson is designed to elicit students' expectations of the course, help instructors select a particular emphasis for the remaining lessons, and give students a sense of ownership of the course. The following topics are covered in the remaining five lessons: the communication process, speaking skills, and basic behavioral styles; assertiveness training; active listening skills; rumors in the workplace and self-reflection; and separating facts from opinion and prediction, stereotypes, and dealing with diversity.
