摘　　要：指纹是公认的法庭科学“证据之首”,指纹显现技术是寻找指纹的第一步,也是关键步骤。笔者在本科生通选课程“化学与现代社会”的“化学与刑事技术”一章中,采用翻转课堂和基于小组学习(Team-Based Learning,TBL)的授课方式,鼓励学生将指纹拟人化为一名面孔多变的“怪盗”,将各种指纹显现技术人格化为指纹显现技术部的侦查员,以趣谈的形式介绍了几种指纹显现技术中所涉及的化学原理,丰富了学生对指纹显现技术科学认识的同时,提高了其科学素养和学习兴趣。Fingerprint can be widely acknowledged as the“first evidence”of forensic science,in which fingerprint manifestation is the first and also the most important step to discover latent fingerprint.Flipped classroom and team-based learning modes have been implemented in the chapter of“chemistry and criminal science and technology”of Chemistry and Society course.Students were encouraged to consult relevant references in advance and participated in the team discussion in class.Herein,the fingerprint is personified into a“mysterious thief”with multiple faces,while various fingerprint display technologies are personified into investigators of the fingerprint department.Collectively,this teaching strategy can popularize the chemical principles of several fingerprint techniques to students,enrich their scientific understanding of the fingerprint display technology,and improve their scientific quality and learning interests.
