In this study I analysed world geography and travel geography curriculum through neo-liberal and critical viewpoints of global citizenship education(GCED). They have many contents about the understanding of diversity which deals in GCED importantly. Two geography curriculums provide many contents of GCED with neo-liberal viewpoint. World geography includes critical viewpoint based on regional conflicts, desertification problems, regional separation movements, righteous distribution of resources etc. The critical viewpoint of GCED in world geography emphasizes the critical understanding of disputes, regional issues, distribution etc. with structural aspect, and guides the realization of justice with problems solutions of these. Travel geography guides students’ identification about unfairness and injustice of travel, and emphasizes travelers’ responsibility, fairness and alternatives. But this travel geography is in circle of neo-liberalism viewpoint mainly. The understanding of diversity in two geographies provides important contents for GCED in schools. Geography make a understanding of diversity with other’s perspectives objectively, but it can neglect the critical and structural understanding about diverse landscape, culture, environment, issues, and travel etc. So geography is necessary to deal critical viewpoint also, because geography has mainly neo-liberal viewpoint. Geography teachers should have the harmony of neo-liberal viewpoint and critical viewpoint to contribute on development of global citizens. Geography teachers should critically re-conceptualize geography curriculum and reconstruct the contents of textbook. And students is necessary to aim transformative learning to understand global diversity and critically participate with global issues in everyday life.
