STEM education aims to cultivate students' core literacy through the application of interdisciplinary knowledge to solve real-world problems. In view of the problems existing in the implementation of STEM integrated courses, such as " the lack of overarching goals to clarify the relationship between subject concepts, lack of explicit representations reflecting the intersections and sequences of subject concepts, and lack of coherence and gradient between interdisciplinary task situations ", this paper proposes a new approach of STEM integrated curriculum design with "big concepts". Firstly, based on Ausubel's meaningful learning theory, an abstract conceptual hierarchy framework from is formulated from "concrete concept, discipline concept to interdisciplinary concept", which provides an explicit representation approach to clarify the logical relationship between interdisciplinary concepts. Secondly, learning from foreign experiences in STEM integrated curriculum design around big concepts, the STEM curriculum design model with "big concept" is constructed, and the cross-disciplinary integration mechanism and the specific path of curriculum implementation in STEM integrated courses are explained. Finally, the scratch programming teaching practice with the project theme of "how to make paper aircraft fly longer?" are conducted. The value of the research lies in exploring the practical approach of coupling big concepts with STEM integrated courses, and providing a reference for primary and secondary school teachers to carry out the STEM interdisciplinary teaching.
