Abstract: Analytical chemistry serves as a fundamental compulsory course for chemistry majors, providing essential groundwork for students’ subsequent academic studies and professional practice. Real-world problems, derived from actual societal scenarios, are incorporated into teaching to create authentic learning contexts that bridge theoretical knowledge with practical applications. This study demonstrates the implementation of a real-world problem-oriented teaching approach through three representative topics: error analysis, acid-base titration reactions, and redox reactions. The proposed pedagogical model not only equips students with solid theoretical foundations and cultivates rigorous scientific thinking, but also enhances their capacity to address practical challenges in future scientific research and industrial applications.
