以问题为导向的教学思路刍议--以“串联型稳压电源”的教学为例

Discussionon Problem-oriented Teaching Ideas--Taking the Teaching of"Series Stabilized Voltage Power Supply"as an Example

教学思路是教师对教学过程的思考、安排和策划,表现为层次清晰、过程流畅,核心在于课程内容的巧妙变化,学生能得到高效的知识建构与训练。串联型稳压电源是《模拟电子技术》课程中的一个综合性较强的教学内容,将知识认知过程分为四个层次:基本电路-改进电路-完整电路-电路模型。前面三部分体现了以问题为导向,提出问题,分析问题,解决问题的认识发展过程;电路模型是在完整电路的基础上进行归纳与总结的结果,是进一步抽象出来的一般的系统框图,是认识的高级阶段。认识过程由浅入深,学生的创新能力在不断解决问题的过程中得到了锻炼和提高。

The teaching idea is the teacher’s thinking,arrangementand planning of the teaching process,which is characterized by clear level and smooth process.The core lies in the ingenious change of the course content,so that students can get efficient knowledge construction and training.Series regulated power supply is a comprehensive teaching content in the course of analog electronic technology.The process of knowledge cognition is divided into four levels:basic circuit-improved circuit-completed circuit-circuit model.The first three parts embody the development process of problem-oriented,raising,analyzing and solving problems.The circuit model is the result of induction and summary on the basis of the complete circuit.It is a general system diagram which is further abstracted.It is an advanced stage of understanding.In the process of understanding,students’innovation ability has been trained and improved in the process of constantly solving problems.
