“抽样定理”混合式教学设计方法研究

Research on the Mixed Teaching Design Method of"Sampling Theorem"

以"信号与系统"课程中的"抽样定理"为实践对象,从教学的重难点和学情出发,基于"一种工具、两类资源"——雨课堂工具、学堂在线MOOC资源和校内网络教学平台资源,对线上和线下相结合的混合式教学模式开展教学方法研究。依据"抽样定理"教学内容中各知识点的特点进行教学设计,综合运用动态图形演示、音频文件、MATLAB仿真、实验箱实验等多元化的教学手段,融合讲授法、启发式、推演式、案例式等多种教学方法,加强理论和实践的融合。教学实践表明,对"抽样定理"知识点进行混合式教学设计不仅可以调动学生主动参与课堂的热情,而且有效地加深了学生对知识点的理解和应用,取得了良好的教学效果。该教学设计方法也为其他教学内容的混合式课程设计提供了很好的参考。

Taking the "sampling theorem" in the course of "signal and system" as the practice object, starting from the key and difficult points of teaching and learning situation, based on "one tool, two kinds of resources"-rain classroom tools, school online MOOC resources and school online teaching platform resources, this paper studies the hybrid teaching mode of online and offline combination. According to the characteristics of each knowledge point in the teaching content of "sampling theorem", the teaching design is carried out by comprehensively using various teaching methods such as dynamic graphic demonstration, audio file, matlab simulation, experiment box experiment, etc., and integrating teaching method, heuristic method,deduction method, case method, etc., so as to strengthen the integration of theory and practice. The teaching practice shows that the mixed teaching design of "sampling theorem" knowledge points can not only arouse the enthusiasm of students to participate in the classroom actively, but also effectively deepen students’ understanding and application of knowledge points and achieve good teaching results. The teaching design method also provides a good reference for the mixed curriculum design of other teaching contents.
