Democratic civic education is the mechanism of political-socialization. To reach the goal, the curriculum must include the core values and social integration of democratic politics; meanwhile, there must be a logical relationship between these two key elements. This study begins with the discussion on the core values and the fundamentals of democracy. Furthermore, it states that democratic fundamentals construct the curriculum for Civics and that the practice of civic education depends on public reason, which is essential for civic education. Finally, it argues that Civics is not the teaching of social science knowledge or the indoctrination of a moral creed. Instead, the course should aim to develop future citizens’competence in making ethical and practical decisions. To achieve this ultimate goal, it is necessary to check if school is a“democratic public sphere.”Through analyzing the content and the format of the current curriculum, the researcher hopes to provide insightful guidelines for the evaluation, modification or development of the future Civics curriculum in Taiwan.
