The purpose of this study was to clarify the teacher’s expertise in observation action that is important for teachers to teach P.E. Observation in ball games was set as the object. In order to clarify the feature of focusing of the observer at the time of observation of a game, a view trackersystem was implemented.As a result, it became clear that the ability to observe was classified according to two viewpoints. One was “what did he/she see (look at) in the game?” (ball or whole game). Another was “how did he/she recognize the game?” (Current play or future play). “The unskilled eye group”, “the player eye group”, “the special player eye group”, and “the coach eye group” were labeled based on those features. That is, a teacher’s expertise of observation might be found by the viewpoint of “what”and “why”. From the above thing, as a result of considering the relation of a change and its development process of observation action, four conclusions were able to be drawn hereafter.(1) What performance is recognized for.(2) What a game situation is recognized for in observation.(3) What tactical understanding can carry out.(4) What is observed with a large peripheral vision.
