摘要
对比分析法是一种重要的教学实践方法,设计合理的对比分析法可以将教学效果推向更高层次,其关键之处在于如何寻找一组适合作为对比分析的教学素材。本文针对电力电子技术课,以BUCK与BOOST DC-DC变换器、单相与三相二极管整流器以及单相功率因数校正器的输出电解电容参数选择为例,给出一种对比分析教学设计案例。结果表明,设计合理和对比性强的对比分析教学可以加深学生对许多似是而非知识的理解,从而积累更多的直观经验,自然而然地追求深层次学习。
Contrastive an alysis is an important teachi ng practice method,and well-designed contrastive analysis teachi ng method can push forward the teaching effect to a higher level.The key is how to find a group of teachi ng materials applicable to contrastive analysis.In the paper,as for power electronic technology course,taking the output electrolytic capacitor parameter selecti ons for in stance for Buck and boost DC-DC con verters,sin gle-phase and three-phase diode rectifiers and sin gle-phase power factor corrector,a comparative analysis teachi ng practice is provided.The results show that reasonably-designed mnd strongly comparative analysis teaching can help students acquire a better understanding of much specious knowledge,accumulate more intuitive experienee and pursue deeper learning consciously.
