This teacher's guide to unit 5 of the 12th-grade second-semester "Comparing Political Experiences" course provides specific objectives and instructional procedures for each of the five activities that focus on the case study of the Cummins Engine Company. In addition, the guide provides instructions for coordinating the use of the student text, audiovisual aids, and skill kit for the unit. The introduction includes a statement of the general rationale, knowledge objectives, analytical skill objectives, moral-reasoning skill objectives, participation skill objectives, instructional design and procedures, and evaluation materials for the course and the unit. A major objective of the study of the Cummins Engine Company is that it serves as an example of a system experiencing development. Learning about issues of growth and job security at Cummins establishes this concept of political development. In addition, the Cummins documentary provides information about work environments as political systems. Students observe the changing pattern of development in the multinational corporation and then may apply the concept to new and different situations. Included are reaction forms to be filled out by the teacher to evaluate the effectiveness of the unit. (Author/DE)
