Against the backdrop of the Curriculum Standards for General Senior Secondary School Geography: Daily Revision Edition (2017 Edition, Revised in 2025), which emphasises the cultivation of core competencies and context-based problemsolving teaching, this paper integrates real-world 3D technology into thematic geography teaching. It creates an immersive and interactive learning environment for students, guiding them to pose, analyse and solve problems within the comprehensive context of ‘unveiling the true face of Mount Lu’, summarise patterns, and achieve a comprehensive integration of knowledge and a gradual deepening of thinking. The organic integration of real-world 3D technology with thematic geography teaching can eff ectively overcome the limitations of traditional two-dimensional images in terms of spatial intuitiveness and holistic understanding. It supports students in solving complex geographical problems through independent inquiry within a three-dimensional spatial environment, providing an innovative digital transformation paradigm for cultivating students’ geographical core competencies.
