Peer tutoring is the system of instruction in which learners help each other and learn by teaching. Tutoring schemes have been used in a variety of contexts--with students teaching students, students teaching school pupils, non-professional adults teaching adults and children, and pupils teaching pupils. This book: (1) describes specimen tutoring schemes; (2) analyses objectives; (3) outlines research findings on the effectiveness of peer tutoring; (4) indicates how tutoring can be developed in schools and in higher education; (5) considers one major tutoring scheme in detail ("the Pimlico Connection"); and (6) offers practical suggestions on how to set up a peer tutoring scheme.
