In this period of rapid social changes, social issues which arouse concern also increase, therefore, with the implementation of issue curriculum, the connection of school education and the society can be strongly enhanced, enabling the students to develop critical thinking and problem-solving ability. However, there are still difficulties for integrating social issues in instruction. Due to this reason, the new Curriculum Guidelines of 12-year Basic Education integrate the major contents of social issues into related fields without setting dedicated independent curriculum guideline solely for that purpose to make the desire change happen. In this context, the teachers’ understanding of the new curriculum guidelines should be strengthened. Second, issue curriculum should be transformed in formal, informal, and hidden curriculum with diversified teaching methods and materials, so that the holistic integration can be achieved. Finally, the curriculum development competence of teachers should be promoted to upgrade the quality of issues-centered curriculum.
