This volume of the Michigan Speech Association curriculum guide--an expanded edition of the 1968 MSA guide (ED 026 393)--is designed for high school students and focuses on the discussion process. "Human Interaction"--the foundation of the discussion process--is the first of three units. The unit is intended to help the student acquire awareness of self and his relationship with others. Unit two, "Preparing for Discussion," introduces the student to the techniques which will enable him to function effectively in discussion. It is the purpose of this unit to assist the student in developing the skills essential for effective, meaningful participation in discussion groups. "Participating in Discussion," the third unit, examines the types of discussion groups, membership and leadership responsibilities, and styles of participant behavior. Each unit is composed of objectives, content outline, learning experiences, a bibliography, and a supplementary audio visual materials list. (LG)
