案例驱动教学法在工科专业核心课程中的设计与实践——以现代数字通信课程为例

Design and Practice of Case-Driven Teaching Method in Core Engineering Courses—Taking Modern Digital Communication as an Example

摘要: 以“学以致用”为理念，通过“基于超宽带(Ultra-Wide Band, UWB)定位的燃煤电厂输煤系统人员安全防护”教学案例，针对“现代数字通信”教学中存在的理论性强、抽象难懂、学习难度大等问题，探索基于信号参量估计等相关知识点，以解决高风险地区的人员定位问题。本实施方案，构建“课前靶向预习–课中案例深化–课后协作实践”的闭环教学模式，结果显示可以提高学生对知识点的掌握效率，为高校案例驱动教学法设计提供有效的理论参考与实践路径。

Abstract: Guided by the concept of “learning for practice”, this paper explores the application of knowledge points such as signal parameter estimation to solve the personnel positioning problem in high-risk areas, relying on the teaching case of “Personnel Safety Protection for Coal Handling System in Coal-Fired Power Plants Based on Ultra-Wide Band (UWB) Positioning”. Aiming at the problems existing in the teaching of Modern Digital Communication, including strong theoretical nature, abstract and difficult content, and high learning difficulty, this implementation scheme constructs a closed-loop teaching mode of “targeted preview before class - in-depth case analysis in class - collaborative practice after class”. The results show that this mode can improve students’ efficiency in mastering knowledge points, and provide effective theoretical reference and practical path for the design of case-driven teaching in colleges and universities.
