After the junta came to power in May 2014, the military government started exercising their nation-centric hegemony through the educational policies and curriculum planning. Contemporary curriculum reform is employed as a mechanism for maintaining the status quo of elites group who have held privileged positions among the Thais. Looking through the social studies curriculum, it becomes the centerpiece of public schools' efforts to cultivate younger generations into what it means to be "Thainess." However, Thainess becomes inevitably hybrid to certain extents in the era of globalization. By looking into the contemporary context of education from the political dimensions of curriculum and cultural studies, I argue that if educationalists are to educate young Thais for global citizenship in today's pluralistic society, the social studies curriculum must go beyond the Siamese colonization of knowledge construction, and also provides pedagogical spaces of the experiences, knowledge, and perspectives of diverse people in Thai society.
