Impact of Peer Tutoring on Mathematic Learning in Multi-Grade Classes Using Single-Subject Design and Qualitative Study

Educational theories and research imply the academic and social advantages of peer tutoring-based instructional situations. The purpose of the present study was to investigate and compare the impact of three types of peer tutoring on students’ mathematic achievement and motivation in multi-grade classes. The research sample consisted of two multi-grade classes selected from villages in Yasouj City during academic year 2015-2016. Sample members were selected via purposeful sampling method and were randomly assigned to control and test groups. The research instru-ments included teacher-made tests and semi-structured interviews with parents and tea-chers. The control group subjects were instruc-ted by traditional method of teaching. Fin- dings showed that not only peer-tutoring method had a considerable effect on students’ mathematical achievement, but also led to improved motivation for mathematics learning, social relationships, cooperation and team work inclinations among them.
