动态电路暂态过程的探究性教学

Enquiry Teaching for Transient Process of Dynamic Circuits

笔者结合多年的"电路"课程教学经验,设计并实践了以暂态过程为内容的探究性教学模式。本文设立若干问题作为引导后,通过"探究性的教与学"、"探究性的做"和"探究性的论"三个实施阶段,不仅把动态电路的暂态过程的经典(时域)法和拉普拉斯变换(频域)法的知识点传授给学生,而且创设出一种科学探究的情境,将知识的掌握和科学方法的熏陶有机结合起来,取得了较好的教学效果。

Based on enquiry teaching theory and experiences in teaching Electric Circuits course, this paper pres- ents a problem-based teaching model designed for transient process of dynamic circuits. Guided by some questions designed by teachers, students go through three processes： enquiry-based teaching and learning, enquiry-based simulation, enquiry-based discuss. The knowledge of dynamic circuits is taught, and the circumstance of scientific enquiry is also set up to help students to research. It is proved that the model achieved well results.
