The purpose of this study is to explore the cultural experience of children in YouTube. This study aims to find explaination about the ways in which children communicate with others and oneself in YouTube, which is a platform afford users to express, communicate and network. Ultimately, this paper aims to draw some implications for how education should response to the media culture that has a great impact on the children s real life. For this purpose, two elementary schools placed in the Gyeonggi province were chosen. Focus group interviews with children in grades 5-6 were conducted. In addition, to better understand the context of media use of children, in-depth interviews were held with teachers and experts. Research shows that children experience and perceive YouTube as a place to exchange emotions, a space of informal learning, a space of identity building and experimentation. At the same time, children are accumulating empirical knowledge about YouTube through their trial and error in YouTube. This study suggests that to support children’s active and healthy usage of YouTube and eventually digital media, teachers’ and parents’ interventions based on appropriate understandings of young people’s meaning-making of the media are necessary.
