“抽样定理”混合教学方法设计研究

Research of "Sampling Theorem" Mixed Teaching Method Design

结合信号与系统课程教学现状,提出采用STEM教育科学表达?点"抽样定理"为例,综合运用仿真软件、视频文件、动画形象化讲解等多种教学手段,基于超星学习通构建线上和线下混合教学模式,加强学生对知识的理解和应用;设计多层综合评价体系,注重学生过程学习能力的培养。实践表明,采用赛耶模型设计教学活动不仅调动了学生课堂热情,提高学生独立思考能力和分析能力,培养学生工程思维及创新能力,取得了良好的教学成果。

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.
