The aim of this study is to inquire into the diagnoses on the obstructive factors in physical education class and how physical education teachers should treat them. To perform this aim, the qualitative research methods was adopted. And the six physical education teachers in the secondary school were the subjects of the investigation. Many physical education teachers pointed that the obstructive factors are firstly, the non-reality on the aspect of physical environments such as space, institution and environment, secondly, the noninterference on the aspect of structures related to the practical operation of physical education class and teaching-learning activity evaluation and thirdly, the closure on the aspect of relations such as cooperation and communication for the teaching activities among physical education teachers. Besides, they pointed that the main obstructive factors are also fourthly, the non-suitability on the aspect of theories such as physical education theory and curriculum, the development of the text book and teacher's manual, fifthly, the multi-responsibility on the aspect of duties of physical education teachers in school, sixthly, the narrow-mindedness on the aspect of recognition related to physical education, and lastly, the formality on the aspect of systems such as research study, workshop and inspectors' guidance. When it comes to the way to handle the obstructive factors, many teachers showed their convenience-favored features to accept and adjust themselves to the realistic interests, rather than to criticize and reform the present demands and difficulties. And the favor of convenience was observed apparently on the curriculum procedure such as the aspect of teaching objectives, selection of contents, organization of contents and evaluation.
