Based on the flipped classroom concept, new experimental teaching method for organic chemistry experiments is explored with the recrystallization of diphenylmethanol as a practice case. Students were guided to independently design experimental procedures, study different single-solvent and mixed-solvent systems, and assess the yield and purity of the products using analytical balance and high-performance liquid chromatography instruments. The results indicate that the new teaching approach effectively enhances students' learning initiative, experimental design ability, innovative thinking, and scientific literacy, providing a new model for the teaching of organic chemistry experiments.
