基于“两性一度”的信号与系统实践教学探索

Practical teaching of Signals and Systems course based on standard of"high-level,innovative and challenging"

目的:探索“两性一度”标准下的项目驱动式教学法在信号与系统课程中的实践应用。方法:结合学校专业实际情况,立足学科优势和科研前沿,基于生物雷达基带信号的MATLAB计算仿真开展项目驱动式教学,以学员为中心有机结合选题、课外自学与课堂教学,通过讲授项目背景、现场实物展示、演示仿真方法、师生互动讨论、课下知识拓展等教学方法进行信号与系统实践教学。结果:采用该教学模式可有效提高学员的自主学习能力和学习效果,对教员教学水平的提高也有重要的促进作用。结论:采用该教学方法可以有效提高信号与系统课程的教学效果,为“两性一度”教学改革研究提供了参考。

Objective To explore the practical application of the project-driven teaching method under the"high-level,innovative and challenging"standard in the Signal and Systems course.Methods The project-driven teaching was carried out based on MATLAB computational simulation of bio-radar baseband signals with considerations on the actual situation of the school,the advantages of the discipline and the forefront of scientific research.The practical teaching of Signals and Systems course was implemented with the students as the center,which involved in topic selection,extra-curricular self-learning,classroom teaching,project background introduction,on-site physical display,demonstrating simulation,interactive student-teacher discussion and off-class knowledge expansion.Results The teaching mode proposed efficiently enhanced the independent learning ability and learning effect of the students,and also promoted the teaching level of the instructors.Conclusion The teaching mode proposed improves the teaching efficacy of the Signal and Systems course,and references are provided for the teaching reform of"high-level,innovative and challenging".[Chinese Medical Equipment Journal,2022,43(3):86-89]
