摘　　要：本文提出了在电工学课堂教学中进行创新教育的必要性,介绍了引入创新教育的几种做法及其例子;文中还指出了电工学教材中关于"提感性负载高功率因数只能并联电容而不能串联电容"和"三相不对称负载Y接法无中线时负载电压必定不对称"这两个结论存在的问题,最后指出了引入创新教育应该持有的正确态度。This paper raises the necessity of the introduction of innovative education in electrical engineering class and introduces some methods and their examples to introduce innovative education in electrical engineering class.At the same time,the article points out the problem of the two conclusion on 'to enhancing the power factor of inductive load can only use parallel-capacitors and not use series-capacitors' and 'if three-phase asymmetric load connected by Y-connection is not neutral conductor,the load voltage must be asymmetric'.Finally,the thesis illustrates the correct attitude towards introduing innovative education in class.
