Abstract:From the perspective of scientific and engineering practice, the unique value of integrating the "small and big history" narrative into the general technology classroom lies in providing a deep cognitive framework that goes beyond traditional skills training. By constructing a "scale integration" model, opening up the path of teaching practice, and guiding students to examine technical practice from scales such as the universe, the Earth, human history, and the project itself, it can effectively promote the transformation of scientific and engineering practice from simple skills training to in-depth cognitive construction, providing an operational practical paradigm for the integration of technical literacy and humanistic spirit in education.
