Peer tutoring and other innovative uses of students in teaching roles have received considerable attention because of the academic and social gains which can be observed among participating children. Teachers who want to try peer tutoring often encounter difficulty in devising workable programs for their own classrooms, however, because most currently available information fails to integrate what has been learned from individual projects throughout the country. This interpretive study combines an examination of relevant literature and field observations of several ongoing peer tutoring programs in a guide for school personnel. The guide contains descriptions of both structured and flexible approaches to tutoring in reading (8 programs), all subjects (3 programs), spelling/English (1 program), and math (1 program). It also provides suggestions for teachers on how to design and implement a program of peer tutoring which is responsive to the particular needs of their individual classrooms. The bibliography lists 206 published articles, ERIC documents, and doctoral dissertations on peer tutoring. (Author/MKM)
