Abstract
The purpose of this study is to determine the role of parental involvement in kindergarten as a child rearing support. Observations were made of a Parental Involvement Program, and the parents and kindergarten teachers were surveyed by questionnaires. The results show that the parents gained relief from watching their children's daily lives in kindergarten and understood better the teacher's works regarding care for children. Teachers learned about how parents reared their children and about their problems. This experience led both parents and teachers to understand each other better and helped make a stronger relationship for caring for their children. However, parents felt some difficulties in Parental Involvement. This learning and conflict will help foster as a community of practice based on Lave and Wenger's theory of Legitimate Peripheral Participation.
