| 摘 要： | "测量原理"是测控技术与仪器专业的一门学科基础课。由于测量科学技术形态的复杂性和课堂讲授学时的限制,该课程采用抽象的、形式化的公式语言符号来表达一种凝练的知识结构,将各种测量原理和方法的外延知识最大限度地化简,因而教学难度极大。为了让学生更好地理解课程的各重难点知识,特引入PBL教学法,通过问题引导学生积极深入地思考,从而领会更加透彻,掌握更加牢固。首先系统梳理课程知识点,通过分析测量信号区别度这个知识点的特点,将"什么是区别度"和"为什么研究区别度"两个根本问题细化为10个具体问题进行教学实践,取得了良好的教学效果。

| Abstract: | "Measurement Principle " is a basic course for Measurement & Control Technology and Instrument major. Because of the complexity of measurement science and technology and the limitation of teaching hours in class,the course uses abstract and formal formula language symbols to express a concise knowledge structure,and simplifies the extensive knowledge of various measurement principles and methods to the greatest extent. Therefore,it is extremely difficult to teach. In order to enable students to better understand the important and difficult knowledge of the course,Problem-based Learning( PBL) method is specially introduced to guide students to think actively and deeply through problems,so as to make students understand the knowledge more thoroughly and firmly. In this paper,the course knowledge points are systematically sorted out firstly. By analyzing the characteristics of the knowledge points of measurement signal discrimination,the two fundamental questions of "what is discrimination"and "why study discrimination"are divided into 10 specific questions which has achieved good teaching results. |
