新工科背景下信号与系统课程的混合式教学改革探索

Exploration on the Hybrid Teaching Reform of Signal and System Courses in the Context of New Engineering

摘要: 信号与系统是电子信息类专业的专业基础课程，对后续专业课程的学习具有举足轻重的作用。然而，该课程知识点多、抽象且逻辑性强，学生学好比较困难。鉴于此，本文将采用线上线下混合式的教学方式，建设线上资源，每次课前提前发布线上学习任务，线下课堂主要梳理知识脉络、帮助学生解决疑难问题，解决课时少不够用的问题；以教师的科研项目中信号的处理、系统的分析为切入点，设计综合实验内容，提升学生理论应用实践的体验感和获得感，激发学生学习兴趣；改革课程评价与质量保障机制，通过多渠道监测与评价，使教与学的过程紧密相连、相互促进。

Abstract: Signal and system is a professional basic course of electronic information major, which plays a decisive role in the learning of subsequent professional courses. However, the course is knowledgeable, abstract and logical, and it is difficult for students to learn well. In view of this, this paper will adopt a hybrid online and offline teaching method, build online resources, release online learning tasks before each class, and offline classrooms will mainly sort out the knowledge context, help students solve difficult problems, which solves the problem of insufficient class time; Taking the signal processing and systematic analysis of teachers’ scientific research projects as the starting point, some comprehensive experimental contents are designed to enhance students’ sense of experience and acquisition in theoretical application and practice, and stimulate students’ interest in learning; Reforming the curriculum evaluation and quality assurance mechanism, and making the teaching and learning process closely linked and mutually reinforcing through multi-channel monitoring and evaluation.
