摘要
RC桥式振荡电路是"模拟电子技术"课程中的重要内容。在教学中,如何理解正弦波振荡电路的振荡条件、组成要素及工作原理,也是教学难点之一。本文提出了一种新的教学思路,采用了演示导入、设疑激趣和启思解疑的探究型教学模式,为改进RC桥式振荡电路的教学提供了有益的建议,实践表明该思路有效地改善了教学效果。
Wien bridge oscillator is one of the most important sections of the Analog Electronic Technical course.It is hard for students to master the oscillatory condition,the components and working theory of oscillator.The present paper proposes a new perspective into teaching,which leads the students into the context with demonstration,stimulates interest with puzzles,and then illuminates them with heuristic methods,thus forming an explorative teaching mode.With the application to the class of Wien bridge oscillator,the teaching method is proven to be effective in improving the teaching results.
