The purpose of this thesis is to demonstrate the constructional validity and the internal coherence to develop the right examination sheet which can measure the elementary school stuents enjoyment objectively and precisely. A multidimensional conceptucal framesork of the enjoyment instrument was based on the 1200 children\'s expressions on the physical activity as an open question. The results revealed that the ESVPA consisted of five scales ane 40 items. The mean socres of the five constructs of the ESCPA for the experimental group were higher than those for the controlled group which indicated that the fun-oriented expressive activity for children was effevtive to promote the lovel of enjoyment and the ESCPA can be a valuable measure for the investigation of a concept in chileren\'s physical activity.
