The purpose of this study was to conclusion about the effectiveness of instructional device at physical education which the first writer of this investigation devised from the standpoint of the phenomenology of the Movement Theory of sports. This instructional device is the target developed for study of “pitching”, and that target has a construction which will retreat if a ball hits.
From the lesson practice in “K elementary school” in Hokkaido, we got the possibility of retrogressive target which is made by a lot of hitting ball and motivation for physical activity.
More practical information is required for teachers to improve their teaching. We hope that the findings of this study could contribute the elementary school teachers for their physical education classes.
