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
