This paper, which takes the "Basics of Accounting" course in secondary vocational schools as an example, analyzes the problems in the process of adopting problem-based teaching method(PBL), and then infiltrates a new teaching paradigm-jigsaw teaching method, so that the two supplement and compound each other, reconciling the imperfection of PBL. Jigsaw, as a teaching method, is not only conducive to students' communication, collaboration, critical thinking and leadership skills, but also to rouse students' enthusiasm and initiative in learning.
