Abstract: This study presents nine teaching cases of pharmaceutical chromatography using GeoGebra,integrating visualization,dynamic simulations,and interactive content into classroom demonstrations.This approach transforms traditionally abstract and tedious content into engaging and comprehensible lessons,enabling students to more intuitively grasp key and challenging concepts from the textbook.Additionally,it enhances students' interest in pharmaceutical chromatography and promotes active learning.Moreover,this teaching method facilitates the sharing of instructional resources between teachers and students,thereby improving teaching efficiency.
