The purpose of this study was to investigate the degree of junior school students' positive and negative experiences and the factors that have influence on the experiences of physical education classes during elementary school. To achieve this purpose, quantitative and qualitative research methods were used simultaneously. The conclusions of this study were as follows. First, students had mostly the positive experiences than the negative ones in physical education classes during elementary school days. In addition, the boys had more positive experiences than the girls. Second, students had positive experiences for their activities in interesting events and teachers‘ appropriate teaching methods. Boys had mostly the positive experiences when they played small-sided games of soccer, basketball, etc., and girls had the same experiences when they took part in the unvigorous activities such as play, gossip, etc.. Third, students had negative experiences for the irregular operation of physical education curriculum and teachers' inappropriate teaching methods. Boys had mostly the negative experiences in the cases that physical education classes were substituted by the other subjects, and girls did in the cases that physical education classes were monotonously implemented.
