The four case studies presented in this manual were designed to illustrate different approaches to the preparation of interns for low-income area schools offered by Teacher Corps programs around the country. The introduction presents the objectives of the manual and possibilities for its use. The research background for the case studies is given, and some lessons learned from the studies are discussed. The four case studies, based on interviews with Teacher Corps staff members, are presented in the second section. Each of the studies was organized according to the following topics: (1) the intern's family, socioeconomic, and educational background; (2) the initial orientation period before the Corps Member Training Institute (CMTI), with particular emphasis on any activities aimed at introducing the intern to low-income communities or schools; (3) the intern's experiences at CMTI; (4) post-CMTI activities and courses designed to further acquaint the intern with the low-income community or school; (5) the academic training offered to the intern during the first year; (6) the intern's first year experiences; (7) the intern's community activities during the first year; and (8) the intern's future plans at the end of the first year. Following the case studies are critical reviews written by two educators with differing perspectives on the four studies. The fourth section offers discussion questions and exercises to stimulate further thinking on topics addressed by the case studies. (JD)
