混合式教学实践中的“134N”范式探索与应用——以《数字信号处理》课程为例

Exploration and Application of the"134N"Paradigm in Blended Teaching Practice:A Case Study of Digital Signal Processing Course

数字化背景下,借助信息技术的支持,线上线下混合式教学是激发学生学习主动性的有效手段。以《数字信号处理》课程为例,对线上线下混合式教学进行了探索,结合学校办学定位、新工科人才的培养目标以及信息类学科特点,构建了《数字信号处理》课程的“134N”混合式教学新范式,设计了“看辨提”三阶循环教学结构,强化了项目资源库、教学视频库、思政案例库建设,优化了混合式教学评价方式等。通过教学实践的应用,提升了学生的学习效果,助力学生成长为高素质复合型人才。

Under the digital background,with the support of information technology,online and offline blended teaching is an effective means to stimulate students′learning initiative.Taking Digital Signal Processing course as an example,this paper explores the online and offline blended teaching,builds a new paradigm of"134N"blended teaching of digital signal processing course by combining the orientation of the school,the training goal of new engineering talents and the characteristics of information subjects,designs the three-stage circular teaching structure of"observing-distinguishing-raising",strengthens the construction of project resource bank,teaching video bank,ideological and political case bank,and optimizes the blended teaching evaluation method.Through the application of teaching practice,it improves the learning effect of students and helps students grow into high-quality composite ta-lents.
