In the 2015 revised curriculum, the emphasis was placed on improving the quality of learning by structuring the content around key concepts. However, in the actual curriculum development process, this idea was not faithfully implemented. In this study, based on our experience of participating in the development process of the 2015 revised curriculum, along with a review of the results of research materials, conference materials, and reports, we analyzed the differences in perspectives regarding how content was presented and reviewed some possible improvements. Then, we analyzed subject curricula in Australia that could be an alternative. On the basis of the results, we made the following suggestions on coordinating perspectives on how to present content in the next curriculum. First, when developing guidelines for subject curricula, the general framework team and subject curricula teams should work together. Second, basic research should be conducted to clarify the meaning of the main elements that make up the curriculum in order to promote mutual understanding. Third, the presentation of contents should be improved by fundamentally reviewing the nature and statement of achievement standards in the current curriculum documents.
