Application of the “PAD Classroom+Xuexitong” Model in the Teaching of Analytical Chemistry Based on the Concept of OBE

As a compulsory foundational course for pharmacy majors,Analytical Chemistry is characterized by a vast array of knowledge points and a high level of difficulty,making it challenging for traditional teaching methods to achieve effective outcomes.Based on the Outcome-Based Education (OBE) philosophy,this study uses the analytical chemistry course as an example to explore the reform and innovation of teaching methods by integrating the PAD (Presentation-Assimilation-Discussion) Classroom teaching model with the Xuexitong platform.This approach aims to enhance students' autonomous learning abilities and improve teaching effectiveness,thereby laying a solid foundation for cultivating high-quality,application-oriented pharmaceutical professionals.
