This study aims to critically review the significance of modern citizenship in new circumstances of the times bordering with the globalization and localization, modernization and post-modernization while exploring the direction of social studies education for hybrid-socialization through the third space, a space of possible resistance and production for democracy that has been ambiguous and paradoxically existent among the borders but that has been concealed or excluded by the modern dichotomous setting of boundaries. The Third space has three characteristics. First, it has been created to respond to binaries. Second, it is hybrid. Third, it is open and ambiguous. The ambiguity and instability lay the foundation for openness and creativity. Social studies education for hybrid-socialization is considered as a process in mutually close relationships in terms of educational conditions, contents and methods. the contents of the social studies education need to proactively accommodate the cultural hybrid domains between private and public sectors to use them as teaching materials, and they need to be proactively reconstituted to critical re-imagining spaces as the third space between reality and ideology and between science and art. As the Third space is symbolically represented through metaphors, social studies education accommodates a lot of metaphors. A metaphor, the basic form of symbolic representation, is not just a linguistic expression used for the purpose of arts or rhetoric but a process of understanding where meaningful experiences are acquired. Metaphors lead to new hybrid meanings by making it possible to understand and structuralize a certain domain of experience in other types of domains in terms of empirical significance.
