线上线下混合教学在信号与系统课程中的应用——以“抽样定理”为例

Application of Online and Offline Mixed Teaching for Signal and System Course —A Case Study of Sampling Theorem

摘要: 信号与系统课程是电子信息类一门重要的专业基础课，起承上启下的作用。根据当前我校学生学习时间、空间的灵活性，内容的多样性，课程组对该课程致力于线上线下混合式教学改革。本文以信号与系统课程中一重要知识“抽样定理”为例，从教学内容、教学手段、教学方法、工程应用、课程思政等方面详细讲述线上线下混合教学的具体实施过程。实践教学表明，混合式教学激发了学生学习热情，提高了学生自主学习能力、独立思考和分析问题能力，培养了工程思维能力和团队协作意识，取得了较好的教学效果。

Abstract: The signal and system course is an important professional basic course of electronic information class, which plays the role of connecting the preceding and the following. According to the flexibility of students’ learning time and space and the diversity of content, the curriculum team is committed to the mixed teaching reform of online and offline courses. In this paper, we take the sampling theorem as an example, which is an important knowledge in signal and system course. The implementation processes of online and offline mixed teaching from the aspects of teaching content, teaching means, teaching methods, engineering application, and curriculum thought education are described in detail. Practice teaching shows that mixed teaching stimulates students’ enthusiasm for learning, and improves students’ ability to independent learning, independent thinking and analyzes problems. It cultivates the engineering thinking ability and teamwork consciousness of students, so it achieves a good teaching effect.
