摘 要 分析信号与系统课程传统教学模式存在的问题,以及微课和翻转课堂的优点,从课前学习、课堂讨论、课后巩固和评价考核方式四个方面设计基于翻转课堂的新的教学模式。以零输入响应和零状态响应为案例,详细说明基于翻转课堂的教学设计。实践表明,新的教学模式能充分调动学生学习的主动性和积极性,改善教学效果。

Abstract In this paper, the shortcomings of the conventional tea-ching form for the course of signal and system are analyzed. In addi-tion, the strong points of the micro-lecture and flipped classroom are also showed. A new teaching model is designed based on flipped classroom from four aspects including preview before class, seminar in class, review after class and teaching evaluation. Then, taking zero-input response and zero-state response for example, the teaching designs are illustrated in detailed. The teaching practice shows that the new teaching model can inspire the learning initiative of students and improve the teaching effect.

1 前言
近年来,随着智能手机、数码产品的广泛普及,以及高校无线网络建设的日趋成熟,信息技术的飞速发展推动了高校教育教学模式的巨大转变。各种网络资源,特别是一系列在线公开课如MOOC(Massive Open Online Course)[1],
使得学生获取知识的途径不再局限于课堂和书本。基于慕课+微课的翻转课堂(Flipped Classroom)对传统教学理念和方式产生重大影响。
翻转课堂于2007年由美国林地高中(Woodland Park Highschool)的两名化学教师提出。翻转课堂突破传统的课堂局限,重构教学结构,将传统教学的课内知识传授、课外知识内化的形式翻转为课外知识传授、课内知识内化,让学生在课外时间完成对相关知识点的自主学习,在课堂上进行师生互动、汇报讨论,从而达到更好的教学效果。
信号与系统课程是各高校电气信息类专业开设的一门重要的专业基础课。该门课程的理论性很强,传统的教学方法使学生感到枯燥乏味、难以理解,很难激发学生的学习兴趣,教学效果较差。……
