To facilitate the implementation of the Citizenship, Economics and Society curriculum and to further enhance national education, the Education Bureau organises four knowledge enrichment seminars for secondary school teachers in Hong Kong in the 2022/23 school year. The topics of these four seminars are: (1) Understanding Rights and Duties through the Constitution and the Basic Law; (2) Understanding Our Country’s Political Structure through the Constitution; (3) Our Country’s Policies and Achievements in Improving People’s Livelihood; and (4) Our Country’s Participation in International Affairs. This resource compiles the contents of the four knowledge enrichment seminars, including the key learning points related to the modules of the Citizenship, Economics and Society curriculum, the values and attitudes involved in each module, as well as the learning points related to national education, for teachers’ reference.
