【Abstract】In communications technology course theory teaching, the course content is various, involving abstract concept, and the students feel boring, difficult to understand and grasp the course material. According to the characteristics of the course of pure theory and abstract, designed a teaching demonstration system. Using the system, can make actual demonstration about the abstract concepts and system, in the teaching process, students through the observation and practical experiment, can better grasp the learning content, and improve the learning initiative and enthusiasm. The demo system shortens the distance of theory teaching and practice teaching, combining theory explanation and practical application, deepen students' understanding of theoretical knowledge and mastering application method, to improve the quality of classroom teaching.
【Key words】Communication technology; Teaching demonstration system; Theory teaching; Practice teaching
一、通信技術课程教学的基本情况
通信技术课程是工科院校通信工程、电子信息工程等专业的专业基础必修课程,同时也是非电类理工科专业的重要专业基础选修课。该课程以通信中信号的分析转换为基础,介绍了从电话通信到数据通信,以及移动、微波、卫星通信的整个技术发展和其中的关键技术。是学生深入学习移动通信、传输接入、室内分布等专业课的先修课程。通信技术课程在整个通信专业课程体系中起着承上启下的作用,为学生构建起一个整体的电信网络。
我院的通信技术课程于2009年成为市级精品课程,是我校通信电源、通信线路、移动通信、计算机通信等专业的必修专业基础课。它是一门抽象、理论性强的学科,涵盖高等数学、信号与系统、电路等理论知识,其中有大量的原理、概念和公式。……
