Study of Teaching Material for ''Body Building Exercise'', Targeting Pupils in the Third and Fourth Grades of Elementary School

In this study, we aimed at obtaining a basic knowledge to effectively utilize a G-ball as a teaching material for "Body Building Exercise" by devising and instructing an exercise program using a G-ball, targeting 58 pupils in the third and fourth grades of an elementary school. For the research method, the formative class evaluation and the balance-capability measurement (sitting balance and rollover balance) were used. As a result, it became apparent in the formative class evaluation that the pupils tended to learn pleasantly, actively and friendly. In the balance-capability measurement, it was shown that the average point for the sitting balance increased significantly through the exercise instruction ( p < .05). On the other hand, the average point for rollover balance did not show significant change before and after the instruction. But in both of the tests, it was observed that a pupil whose point was lower in the first period tended to get a higher point in the
