新型翻转课堂在有机化学实验中的应用——以“二苯甲醇的重结晶”为例

Application of a new flipped classroom in organic chemistry experiments: A case study on the recrystallization of diphenylmethanol

摘要

基于翻转课堂理念，探索新的有机化学实验教学方法，并以“二苯甲醇的重结晶”为例进行实践。在实践中，引导学生自主设计实验方案，考察不同单一溶剂及混合溶剂体系，结合分析天平和高效液相色谱仪测定产品产量及纯度。实践结果表明，新的实验教学方式能够有效增强学生学习的主观能动性，提高实验设计能力、创新思维及科研素养，为有机化学实验教学提供了一种新的模式。

Abstract

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.
