This supplement to Volunteer Training and Development: A Manual for Community Groups, provides practical guidance in the selection, writing, and adaptation of effective case materials for specific educational objectives, and develops suitable cases for use by analyzing concrete situations and by offering illustrations of various types. An examination of the case method in the light of its use in informal adult education is found in Chapter 1. An overview of the case method appears in the Addendum. Chapters 2 and 3 contain guidance on using and selecting cases for learning experiences. Chapters 4 and 5 offer suggestions to those new to the method as well as to those concerned with adapting, developing, and writing case materials on their own. In Chapter 6 the authors discuss the role and function of the trainer-leader and make some observations about the importance of a proper climate for the use of the case method. Additional references, worksheets, and a subject index of cases are in the appendix. All the cases contain subject matter appropriate for training in problem-solving, human relations, intergroup and intercultural relations, board and committee work, volunteer-staff responsibilities, role conflict, and attitudinal change.
