“翻转+分段式”有机化学实验教学设计及实践研究

Teaching Design and Practice of“Flip+Segmentation”in Organic Chemistry Experiment Teaching

以FeCl_3·6H_2O催化合成乙酸乙酯为教学内容,采用"翻转+分段式"混合教学方法对整个实验过程进行了改革探索。通过教师准备学习资源,学生自主学习,课堂分段讲解,互动交流以及跟踪评价等,探讨了大学有机化学实验实施"翻转+分段式"混合教学方法的有效途径。实践结果表明:混合教学模式能够显著促进学生对实验内容的理解和掌握,明显增加学生自主操作的时间,还能有效降低实验过程中的安全隐患。

The synthesis of ethyl acetate catalyzed by FeCl3·6 H2O was used as the teaching content. The whole experiment process was reformed and explored by using the "flip+segmentation" mixed teaching method. An effective way of "flip+segmentation"was realized via preparing the learning resources by teachers, students’ self-learning, classroom segmentation, interactive communication and follow-up evaluation during organic chemistry experiment. The practical results show that the mixed teaching mode can significantly promote students’ understanding and mastery of experimental content, significantly increase the time for students to operate autonomously and effectively reduce the safety hazards in the experimental process.
