Dayuan Elementary School is located in Dali District, Taichung City, where the old town "Dali Hao" is located. The curriculum plan leads students to understand the history of the local environment, and through on-site visits and learning, they can discover and perceive problems in the living environment. Teachers use cross-disciplinary logical thinking and design thinking in the curriculum to guide students to develop topical ideas for problem solving. Through space transformation and urban creation planning, they transform old cultural assets and create contemporary value of culture and monuments. Our school's cross-field aesthetic education plan hopes that children will develop through problem-oriented themes and use the combination of cross-field knowledge, with "Cultural Space Transformation-Urban Creative Design" as the main core topic, to solve the problems discovered by students and hope to improve the current situation. . During the implementation of the course, it is expected to improve students' daily application abilities in problem discovery, creative thinking and problem solving, and to cultivate cross-field thinking literacy learning.
