Abstract: The development of instructional resources is a core component of curriculum construction,and high-quality online teaching materials are essential for implementing effective blended learning.To meet the needs of cultivating core competencies in pharmaceutical analysis and to support in-depth learning within a blended teaching framework,this study presents the design and development of the "Pharmaceutical Analysis Case Teaching and Training System." The system was constructed through a systematic approach involving case selection,problem design,and interface development,and has been granted software copyright protection.It can be employed in both theoretical and experimental courses in pharmaceutical analysis,and is also suitable for use by students and independent learners in broader educational contexts.
