Abstract
The spatial cognitive ability, which is indispensable in manufacturing education and daily life, tends to be reduced due to decrease opportunities for learning because of changes in children's play and education. Therefore, in this research, we propose a serious game aiming at improvement of spatial recognition ability. Among them, we proposed a serious game aimed at improving the speed in spatial recognition ability, which was not achieved by previous research. As a result of the experiment, the improvement of the speed in the spatial recognition ability was achieved, and the learner was also conscious of the speed improvement.
