【Abstract】:Based on the current teaching situation of signal and system course, this paper proposes to adopt STEM educational scientific expression -- Saiye model to design course teaching. Taking "Sampling Theorem", a difficult point in signal and system, as an example, a hybrid online and offline teaching mode was built based on Super Star Learning to strengthen students' understanding and application of knowledge by comprehensively using various teaching methods, such as simulation software, video files and animation visualization explanation. Multi-level comprehensive evaluation system is designed to cultivate students' process learning ability. The practice shows that using Saiye model to design teaching activities not only arouse students' enthusiasm in class, improve students' independent thinking ability and analytical ability, cultivate students' engineering thinking and innovation ability, and achieve good teaching results.
【Key words】:saiye model;sampling theorem;mixed teaching;engineering thinking;teaching effect
信号与系统是电子信息类一门重要的基础专业课程,课程在电子信息课程体系中起到承上启下的作用[1],该课程的公式推导繁多、理论性较强以及在工程应用中具有非常重要的背景,因此,学生学习起来普遍反映知识枯燥、难以理解、不能领会知识的内涵、说不清在课程内容讲述的是什么、能有怎样的应用场景,能解决怎样的实际问题,尤其是近些年,STEM教育素养的提出,如何将科学、技术、工程及数学进行有效融合,从工程应用角度引导学生参与学习、主动学习掌握信号理论知识、解决工程实际问题。本文以信号与系统中重要知识点-抽样定理为例结合我校……
