An introduction to the study of American government is the focus on the first unit of the 12th grade level of the FICSS series (Focus on Inner City Social Studies -- see SO 008 271). The five content areas offer an overview of the three major branches of American government, independent regulatory agencies, and politics and elections. The unit develops the concept that each branch of government reaches into the functions of other branches and shows the role of the American government in relation to foreign and military affairs and policies. The unit also stresses the need for active citizen participation to make the government responsive to the needs of the public. The content of the unit includes an introduction; essential materials to teach the course; knowledge, skill, and behavioral objectives; content learning activities; and supplementary resource materials for students and teachers.
