Many arguments about leadership in organization of physical education have been made. But only a little has been mentioned about studies on communication and interaction in a group of teachers or function of leader's behavior in communication-field . And there still remains a wide unexplored domain of a process of PE service producing. Therefore, the purpose of this research was to explain the character of communication-field leader's utterances, and to show the picture of sharing the sense of value for PE teaching. The two sub assignment were 1)to classify the communication-field leader's utterances and to clarify those characteristics in a group of teachers that they shared the sense of value for PE teaching, and 2)to make analysis of the utterance of leader through classification and to show the picture of sharing the knowledge through observing in communication-field. From this research, utterance of leader was classified as follows^ l)to state (a)with bases, (b)without bases, 2)to reform (a)to reform with bases, (b)to reform without bases, 3)to ask question (a)for taking opinion of followers, (b)to convince followers, (c)to pose questions, 4)to specify, 5)to agree, 6)to object, 7)to inform, 8)to decide, 9)to request affairs, 10)to order affairs, ll)to inform affairs, 12)to chair, 13)others. Major findings were summarized as follows: 1. Leader showed the sense of value for PE teaching through perpetual statements, reforming, and agreement. And leader's sense of value was accumulated as each teacher's tacit knowledge. 2. Teacher's sense of value for PE teaching as tacit knowledge wasn't changed into explicit knowledge. In case group, difference between each teacher's tacit knowledge is kept small, but that obstructs renewal of sense of value. The category of communication-field leader in this research will become more accurate through more case studies and theoretical examinations. A causal relationship between communication as a process of PE service producing and outcome of management will be clarified through quantitative analysis.
