To meet teachers' demand for supporting resources for geography textbooks and adapt to the trend of digital transformation in education, Chinese Map Publishing House simultaneously developed and built a supporting digital resource website — the Geography Teaching Resource Platform — upon the official launch of the new edition of Shanghai junior high school geography textbooks. Grounded in teachers' practical needs, the platform adopts a scientifi cally planned column structure, carries out digital resource construction in an orderly manner, and continuously optimizes its content and functions based on user feedback. It was put into use synchronously with the new textbooks. The platform gathers a wide range of high-quality resources from multiple sources, maintains close integration with textbook content, provides standardized and practical teaching map materials, and is equipped with a convenient resource retrieval function, striving to empower teachers and improve teaching effi ciency. In the future, the platform needs to further expand resource forms and coverage, upgrade its functions, and promote the digital transformation of textbooks.
