Practice and Reflection on the Theory-Practice- Virtual Simulation Teaching Model in Gemmology and Materials Technology Course in the Context of Digitalization: Taking the "Ornamental Stone" Course of Shanghai Jian Qiao University as an Example

The Gemmology and Materials Technology program is an interdisciplinary field grounded in mineralogy, mineral deposits and petrology, integrating elements of aesthetics, economics, materials and other disciplines. Its unique nature, coupled with the growing demand for application-oriented talents in the corresponding jewelry industry, has imposed new requirements on talent cultivation in this field. However, with the advancement of information technology, traditional teaching modes show limited effect. Therefore, effectively leveraging digital technologies to achieve professional training objectives has become a critical issue in current educational reform. This paper takes the development of "Ornamental Stone" courses in the Gemmology and Materials Technology program at Shanghai Jian Qiao University as a study case, implementing the "theory-practice-virtual simulation" teaching model under the Outcome-Based Education (OBE) concept and aims to explore the solutions to teaching challenges in specialized courses, enhance the quality of the courses that balance theory and practice, and provide innovative exploration and practical examples for the construction of key undergraduate courses.
