基于PBL的信号与系统课程教学改革

PBL-based Teaching Reform in Signals and Systems Course

针对"信号与系统"课程理论性强、概念抽象的特点和现有教学模式的不足,提出在该课程中引入以问题为导向的PBL(Problem-Based Learning)教学法。分析了PBL教学法的可行性,阐述了PBL教学法的教学过程设计。以抽样定理教学内容为例,介绍了PBL教学法的具体实施过程,对PBL的教学效果和存在问题进行了分析。实际教学效果表明采用PBL教学法有助于提高学生的自主学习能力和综合能力,激发他们对课程的学习兴趣,为信号与系统课程的教学方法改革提供了有益的探索。

The paper,in the light of such features in the Signals and Systems Course as being highly theoretical,abstract and ineffective in terms of teaching methodology,proposes that the problem-based Learning(PBL)teaching method be introduced in this course.Besides,it analyzes the feasibility of PBL teaching method,discusses the teaching process design and introduces the concrete implementation process taking the sampling theorem as an example and finally analyzes the teaching effect and the problems of PBL.The actual teaching results show that the use of PBL teaching method can help students to improve their self-learning ability and comprehensive ability and stimulate their interest in the curriculum.The study is of much reference value to the reform on the teaching method of this course.
