The accumulated data were then put through case record analysis and inductive categorical analysis. The methods of member checking, peer debriefing, and triangulation analysis were used for data verification. The results of the research were as follows. Prior to experiencing music rope-jumping, the students had a low level of perception for the value and meaning of physical education classes. They perceived physical education classes. as an uninteresting and inadequately taught subject. The students replied they avoided P.E. classes mainly because of the negative experiences in interactions with their peers and teachers, and of the continued failure to succeed in physical activities due to their low athletic abilities. However, the music rope-jumping experience enabled the students to re-evaluate the value and meaning of P.E. classes by helping them perceive physical activity as something that is fun, enjoyable, and important. With the help of experience in working with their teammates toward a shared goal, the students could learn social and cooperative skills. In the process of learning new techniques and working to achieve class objectives, the students felt their physical fitness and motor skills were greatly improved.
