基于乙酰苯胺制备实验探索有机化学实验教学改革

Exploration of Organic Chemistry Experiment Teaching Reform Based on the Preparation Experiment of Acetanilide

摘要: 针对传统有机化学实验教学中存在的“重操作、轻思维”“重结果、轻过程”等问题。以乙酰苯胺制备实验为核心载体，从实验教学重结晶环节中存在的问题出发，改进了重结晶装置，拓展了产物熔点测定评价方式，并应用于实验教学实践中。从教学内容优化、教学方法创新、评价体系完善及拓展性实践设计四方面展开改革探索。通过整合绿色化学理念、引入方案对比分析和结合过程评价体系三阶教学模式，有效提升学生实验操作能力、创新思维与科学探究素养，为有机化学实验教学改革提供实践参考。

Abstract: In view of the problems existing in the traditional organic chemistry experiment teaching, such as “heavy operation, light thinking”, “heavy result, light process” and so on. Taking the preparation experiment of acetanilide as the core carrier, starting from the problems existing in the recrystal-lization process of experimental teaching, the recrystallization device was improved, and the evaluation method of product melting point determination was expanded and applied to experimental teaching practice. The reform and exploration are carried out from four aspects: teaching content optimization, teaching method innovation, evaluation system improvement, and extended practice design. By integrating the concept of green chemistry, introducing comparative analysis of schemes, and combining the three-stage teaching mode of process evaluation system, students’ experimental operation ability, innovative thinking, and scientific inquiry literacy are effectively improved, which provides practical reference for the reform of organic chemistry experiment teaching.
