To improve the education, a new design of curriculum is always a part of the process. However, its development usually relies on the change of body of knowledge and class implementation. As a result, it might not succeed since it is compromised with issues in the deployment. In this paper, we propose to introduce a design concept on user experience (UX), which is extensively studied in the software engineering and computer science research, as a design tool. When the curriculum is improved, not only the body of knowledge is changed, the changes also affect all related resources and activities. If some of them was not well prepared, it would become the obstructions. The UX design/analysis is a process that uses meaningful experiences of all users in all aspects, such as resources, management, usability, and implementation. All related action roles to the system in the past is needed to be analyzed. The new curriculum should be designed based on possibility of implementation and optimized based on the user experience in the future. We introduce the study of computing science curriculum design for basic education. The case study has discussions on the analysis, the objective layout on the curriculum development, and the design of the curriculum.
