摘　　要：针对当前“数字信号处理”教学存在的问题,充分利用线上资源和线下翻转课堂的方式,对传统教学模式进行改革。线上通过雨课堂随机点名、弹幕和闯关题的设置,让学生的注意力集中在课堂;通过腾讯会议实时语音通话,随时和学生互动,提升学生的学习兴趣;线下通过翻转课堂,让学生重构知识图谱,排除畏难心理。实施效果表明该教学模式实现了“以教为中心”向“以学为中心”的转变,可为相关课程提供有益借鉴。Aiming at the problems existing in the current teaching mode of Digital Signal Processing course,this paper makes full use of the online teaching resources such as Rain Class,Tencent Conference,and offline flipped classroom teaching methods,breaks the traditional time-space fixed teaching mode,and reforms and optimizes the traditional teaching mode.The setting of random roll call,bullet screen and breakthrough questions in the Rain Class online,let students focus on the class;With Real-time voice call through Tencent Conference,students can communicate at any time to enhance their learning interest;By flipping the classroom offline,students can reconstruct the knowledge map and eliminate the fear of difficulties.The implementation results show that the teaching mode has greatly improved students′classroom satisfaction,realized the transformation from“teaching centered”to“learning centered”,and can provide useful reference for the teaching research of relevant courses.
