Under the requirements of environmental protection and promoting sustainable development, solar energy, as a clean and mature technology in the field of chemistry, plays a significant role in the learning of university and high school chemistry. In Xinjiang, especially in the southern region, there is a large area of saline-alkali soil with various types, heavy salt accumulation, and complex formation, which seriously hinders the sustainable development of agriculture and animal husbandry and ecological environment protection, impeding local economic development. Based on the course "Fundamentals of Materials Engineering," and taking "Solar Energy Desalination for Saline-Alkali Water Treatment in Xinjiang" as a problem-oriented approach, this study adopts a student-centered and teacher-guided teaching model, incorporating a series of driving questions. This not only stimulates students' interest in learning and cultivates higher-order thinking skills but also integrates cutting-edge scientific research information into educational activities, facilitating the integration of "science and education."
