Abstract With the project theme of“Exploring Indigo dye spanning thousands of years”,the teaching of organic dye in fine chemical technology was carried out for undergraduates.The dismantling project includes several key tasks,including understanding the history of dye use,exploring the dyeing principle,designing experimental scheme,preparing and characterizing products,dyeing and recycling practice,and communicating and displaying results.Students gained a preliminary understanding of indigo through pre-class preparation,learned the theoretical knowledge of indigo through guided classes,and applied it in practical classes to deepen their comprehensive understanding of the organic dye indigo.Finally,the integrated goal of“teaching,learning and evaluation”was accomplished through student mutual evaluation,student self-evaluation and teacher evaluation scale.
