摘　　要：S域初值定理和终值定理是"信号与系统"课程教学中的难点,现有教材的缺陷使学生很难理解这两则定理内容。本文提出了一种新的教学方法,以该两则定理的使用条件作为突破口,引导学生掌握定理和其使用条件之间的关联,再讲解定理的证明,可让学生透彻理解教学内容并为后续知识点的学习打好基础。The initial value theorem and final value theorem of S domain are difficult sections of teaching Signals and Systems couse.It′s hard to make students understand the theorems by use the defective textbooks.This paper presents a novel teaching method which use the conditions of the theorems as a breakthrough.Firstly,we guide our students to grasp the link between the theorems and their conditions.Then,we explain the proof of the theorems.Finally,students can understand the course content deeply and lay a solid foundation for the follow-up key points of the follow-up course.
