Abstract This study redevelops textbook contextual materials through a dual lens of curriculum standards and student learning profiles. Centered on the theme “lightweight guardians: metal materials for mobile phone casings”, the framework incorporates two authentic tasks: (1) selecting optimal metal materials for phone casings and (2) simulating industrial processes (e.g., oxide layer removal and formation). By embedding the study of aluminum and aluminum oxide’s chemical properties within these tasks, the design systematically cultivates students’ conceptual understanding of “composition-structure-property-application” relationships. The findings offer a pedagogical model for curriculum reconstruction oriented towards core competencies.
