Since the resumption of Hong Kong's sovereignty by China in 1997, national identification with Chinese has been a policy priority. There has been an increase of National Education which aims at cultivating a Chinese national identity. This study used convenient sampling method on 10 purposively chosen sample of experienced Hong Kong citizenship education teachers, with in-depth interviews as data collection method. The findings reveal that teachers perceive National Education with different aims and teaching methods, and knowledge transmission is highlighted in National Education. There are patriotic, affective, critical thinking approaches, experiential learning and reflective teaching in National Education. Apart from arguing for different pedagogies and assessments in teaching National Education, this paper also calls for recognizing global identity and global citizenship education.[Copyright © Comparative Education Society of Hong Kong].
