Abstract
In this study, the structure of tactics in various ball games was analyzed in order to develop a curriculum for teaching the joy of strategically winning ball games. The authors reviewed theories of tactics in ball games, and categorized the key concepts of tasks focused on tactics. Three major themes of tasks focused on tactics were extracted from the classification of theories dealing with ball games: 'aiming at a target'; 'aiming at a gap'; 'creating a gap and aiming at it'. 'Creating a gap and aiming at it' is the most difficult among the three, and 'aiming at a gap' is more difficult than 'aiming at a target'. These themes were considered to be the core of the system, and seven tasks focused on tactics were subdivided from the core themes to focus on the following aspects: 'the size of target to defend'; 'the existence or non-existence of direct interference'; and 'the direction of the attack and the speed of switching between offense and defense'. According to this analysis, a new system with seven tasks focused on tactics was proposed.
