摘　　要：由于通信课程理论知识非常抽象,在课程教学中学生印象不够深刻。也为了弥补课堂教学模式单一的不足,课程中采取以Multisim仿真实验案例的方式,配合启发引导式教学方法。使学生能够循序渐进的理解原理知识,通过理论计算在实践中改进电路,使学生明白其改进方法和改进过程,并从中受益。文章以具体的三点式振荡器的改进仿真实验为例,从电容三点式逐渐引出克拉泼振荡器、西勒振荡器,并对振荡器的缺陷进行改进。这对于理论的理解和日后深入学习都有很大帮助。此方式经过几年的教学实践,学生积极性高,教学效果良好。,the students can not understand very well in the course teaching.In order to make up for the weaknesses of the traditional course teaching inside the classroom,the Multisim simulation experiment case is adopted in the teaching process,combined with the inspiration-oriented teaching method.It enables students to understand the principle knowledge step by step,optimize the circuit in practice through theoretical calculations,have a deeper comprehension of optimization method and process and benefit from it.In this paper,taking the optimizing simulation experiment of the three-point oscillator as an example,along with the Clapp oscillator and the Seiler oscillator which are extracted from the three-point capacitor gradually,we hope to instruct students to identify and avoid the defects of the oscillator.This is very helpful for students to understand the theory and study further in the future.After several years of teaching practice,students have shown their enthusiasm to this teaching method,which allows us to obtain good teaching results in communication course.
