“自动控制原理”难点知识的背景教学法

Background Didactics for Difficult Knowledge in Automatic Control Principle

“自动控制原理”是自动化专业的必修课,但是与一般工科课程不同,其中一些概念和知识由于脱离具体行业和物理背景,抽象度比较高,难以被学生深刻掌握,往往只能死记硬背,效率低下,无法形成深刻的印象。考虑到“自动控制原理”诞生的背景,把一些抽象概念和知识点建立物理机理解释方式,以及复原产生时代背景的物质基础,进行形象化和历史嵌入处理,通过适当方式转换问题描述方式,利用讲解和学生Matlab实际仿真操作,对比不同途径的结果,帮助学生准确深入掌握相关概念。这种背景教学法使得学生对课程的兴趣和理解都得到有效加强。最后分析了这种教学方式对于讲授教师的基本素质要求。

Automatic Control Principle is a compulsory course in the major of Automation.Different from the classical engineering courses,some concepts and knowledge are highly isolated from a concrete background,which,therefore,is too abstract to be deeply understood by newcomers.The students generally master these concepts by rote with low efficiency,and the in-depth impression cannot be established.Considering the birth background of Automatic Control Principle,the physical mechanism based interpretation for several concepts and knowledge points is established,and the technological background of the era is reproduced.Then,appropriate transformation is employed to reformulate the difficult knowledge into a physical background to help the students to master them precisely and profoundly.In this process,teaching,simulation through Matlab by the students,and result comparisons among different means are effectively combined.This background didactics can enhance the enthusiasm and understanding of the students towards Automatic Control Principle.Finally,the fundamental quality for the teachers to realize the background didactics is investigated and provided.
