With the development of information technology and the long-term planning of national talents, several countries have successively incorporated computational thinking into the curriculum guidelines. In addition to continuing to promote the development of the information curriculum, Taipei City also extends the concept of computational thinking to the lower grades of the elementary school. The researchers used the ADDIE model to design the 〞Star Wars Battle〞 teaching activities, and integrated computational thinking into the life course of elementary school. We hope that the cultivation of computational thinking will enhance students' ability to use computational thinking and information technology tools to solve problems, cooperate and create high-level capabilities.
