The Geography Curriculum Standards for Compulsory Education (2022 Edition) advocate the active implementation of outdoor geographical practice to promote students’deeper engagement in geography learning and provide learning experiences that contribute to the development of geographical key competences. In response to the current implementation of practical assignments in junior high school geography, this study analyzes existing practices and draws on the interdisciplinary practical assignment“Coal in Transformation”at Xijiao Park as a case study. It explores approaches to optimizing practical assignments across fi ve dimensions: theme, format, objectives, content, and resources. It further proposes four implementation strategies: standardizing implementation procedures, providing targeted teacher guidance, strengthening process management, and adopting diversifi ed assessment methods. The study provides a reference for improving the quality of practical assignments in junior high school geography and fostering students’geographical core competencies.
