This study clarifies the scope and sequences of tumble techniques in mat and vaulting box activities from the viewpoint of “taxonomy based on the technical structure of materials” (Okade et al., 1997, p.47) in Apparatus Gymnastics. The targets were two Physical Education Explanations of the Course of Study for Elementary School which were revised in 2008 and 2017. It was found that, in the Physical Education Explanation of the Course of Study for Elementary School which was revised in 2017, the movements of the tumble technique were newly shown in mat activities. Thus, it can be understood that “the taxonomy based on the technical structure of materials” (Okade et al., 1997, pp.46-51) was employed for selection of the teaching material. However, since the tumble movement involved the extremely difficult technique of “neck spring,” it was pointed out that most pupil might fail in performing the movement during lessons. Thus, in future, it is necessary to develop concrete teaching materials and verify the effects of their implementation in lessons.
