基于项目驱动式的CDIO教育理念在《信号与系统》课程中的应用探索

Application Exploration of Project-Driven CDIO Education Concept in Signal and System Course

摘要: 信号与系统课程在电子信息类专业课程体系中有重要的地位，其课程内容与多个专业课程的学习密切相关，同时起着承上启下的作用。该课程的学习效果也直接影响学生对整个专业学习的信心和兴趣。但是该课程存在理论性强的特点，同时教学手段单一，导致学生的学习积极性受到影响，对课程的理解不够深入。为了解决这一问题，本论文将探索以项目的形式践行CDIO (Conceive, Design, Implement, Operate)的教育理念，以项目驱动式的教学模式引导学生进行自主学习，主动思考各个课程之间的内在联系，深入理解专业课程的实际应用价值。本论文将以脑电信号的情绪识别和滤波器的设计两个项目模式为例，以科研项目及实验项目的形式助力本科教学改革，来阐述该模式的具体实施方案，通过合理的方案设计培养学生的工程思维，提高学生的动手能力、协调能力、团队合作能力，在教学中非常值得推广。

Abstract: The course of Signal and System plays an important role in the course system of electronic information specialty. Its course content is closely related to the study of many specialty courses, and it also plays a role of connecting the previous and the next. The learning effect of the course also directly affects the student’s confidence and interest in the study of the whole major. However, this course has the characteristics of strong theory, and the teaching method is simple, which leads to the impact on students’ learning enthusiasm, and the understanding of the course is not deep enough. In order to solve this problem, this paper will explore the CDIO (conceive, design, implement, operate) education concept in the form of projects. The project-driven teaching model guides students to conduct independent learning, actively think about the internal links between various courses, and deeply understand the practical application value of professional courses. This paper will take the two project modes of emotion recognition of EEG signal and filter design as examples, to help undergraduate teaching reform in the form of scientific research projects and experimental projects, to elaborate the specific implementation plan of this mode, through reasonable program design to cultivate students’ engineering thinking, improve students’ practical ability, coordination ability and teamwork ability, which is worthy of promotion in teaching.
