一根导线在电路基础课程中引发的教学思考

The Teaching Inspirations from “A Wire” in the Curricular Course of Circuit Basics

针对一根导线引起电路的改变,学生利用已有的知识解决此问题时,得出了错误的结果,利用Multisim仿真软件和Proteus仿真软件对该电路进行仿真,引导学生理清思路,得出正确的分析方法,从而使学生学会分析、归纳、总结,提高学生综合运用所学知识解决电路基础课程中疑难问题的能力。

To solve the problem caused by the circuit change via a wire,students get a wrong result by using the learnedknowledge.In this study,the two following simulation softwares Multisim and Proteus are used to simulate this circuit toguide students to clarify their thoughts of solving this problem and get right analytical methods,thus making them learn howto analyze,summarize and improve students’ability of synthetically using learned knowledge to solve difficult problems inthe course of circuit basics.
