Intergenerational learning allows the young generation and the old generation to better understand each other. However, in Taiwan, intergenerational learning usually happens in the community or school. The purpose of this study is to explore the influence of an intergenerational communication program on the social skills of the elderly in a day care center. This pre-experiment study adopted the one-group pretest-posttest design. 10 elderly persons were recruited from a day care center in Kaohsiung and 10 kindergarten children were invited to participate in the study. The intergenerational learning was designed in a contrastive way. It was conducted once a week, with an hour for each of the total 5 sessions. Repeated measures were performed before and after the intervention. Data was collected by the interpersonal function scale. The study concluded that intergenerational learning is useful and valuable for improving interpersonal relationship functions for the elderly in a day care center.
