Abstract: In the instrumental analysis laboratory courses designed for undergraduate students enrolled in the Strengthening Basic Disciplines Program, interactive electronic courseware was implemented as pre-laboratory learning materials. This approach effectively combined online and offline learning modalities, enabling targeted delivery of advanced course content. The methodology demonstrated multiple benefits: it enhanced student engagement, improved experimental techniques, and cultivated innovative research thinking. Furthermore, this study presents a novel approach for developing digital educational resources in the context of integrated undergraduate-graduate laboratory course development.

Key words: Interactive electronic courseware, UV-Vis spectroscopy laboratory course, Digital learning resources
