Abstract
The purpose of this study was to clarify the psychological transformation processes in children resulting from a throwing training program implemented in physical education classes. Eight fourth-grade primary school children were selected for semi-structured interviews, and they were analyzed using Modified Grounded Theory Approach (M-GTA). The findings of this study lead to the development of 14 concepts, 4 categories (motivation; reflection on the throwing process; self-confidence; generalization of movements), and 4 sub-categories within them. This study concluded that “motivation” arising from the understanding of throwing instructions and teaching materials promotes “reflections on the throwing process,” which in turn, increases“ self-confidence.” Moreover, it appears that the increased“ self-confidence” in children improves “motivation” and the“ generalization of movements”.
