摘要：

介绍了阿司匹林的制备、纯化及结构鉴定，着重介绍了实验各个阶段的教学方法、教学目的及所取得的教学成果。通过问题导向式翻转课堂实验教学法，培养学生自主学习的能力及综合实验能力；通过独立实验，分组讨论，学生独立思考与合作能力得到提高。

关键词: 阿司匹林, 综合性实验, 翻转课堂, 问题导向式教学法

Abstract:

This paper introduces the preparation, purification and structure identification of aspirin, especially the teaching method, purpose and result at distinct stages of the experiment. Through problem-based learning with flipped classroom, students' active learning ability and comprehensive experimental ability was improved. By doing experiments independently and discussing the experiment result in groups, students' ability of independent thinking and cooperation was strengthened.

Key words: Aspirin, Comprehensive experiment, Flipped classroom, Problem-based learning
