Although there was an introduction of the class with in mind learner's individual learning ability as a method improving problems of the class which consists of students with various kinds of levels, it was a burden to both teacher and students because of many realistic problems. In this paper, we investigate the efficiency of peer tutoring teaching method which is the one that students having a superior ability for learning become peer tutors and they teach other peer tutee under the teacher's guidance and supervision. After we apply the class-wide peer tutoring to some sophomore classes, we obtain that this teaching method affects positively the students's learning achievement and learning attitude in mathematics class. In particular, we obtain that the peer tutoring is more effective in three to one group than in one to one group.
