通信技术课程理论教学中,由于课程内容繁多,涉及概念抽象,学生感到枯燥,对课程内容难以理解和掌握。针对该课程纯理论和抽象的特点,设计了一个教学演示系统。使用该系统,可将教学过程中抽象的概念和系统进行实际演示,学生通过观察和动手试验,能够更好掌握所学内容,提高学习的主动性和积极性。该演示系统拉近了理论教学和实践教学的距离,将理论讲解和实际应用紧密结合起来,加深了学生对理论知识的理解和应用方法的掌握,提高了课堂教学质量。 In the teaching of communication technology course theory, students are boring due to the large number of courses and abstract concepts, making it difficult to understand and master the contents of the course. In view of purely theoretical and abstract features of the course, a teaching demonstration system was designed. Using this system, the abstract concepts and systems in the teaching process can be actually demonstrated. Through observation and hands-on experiments, students can better understand what they have learned and enhance the initiative and enthusiasm for learning. The demonstration system has narrowed the distance between theoretical teaching and practical teaching, closely integrating theoretical explanations with practical applications, deepening students’ understanding of the theoretical knowledge and mastery of application methods, and improving the quality of classroom teaching.
