基于“MOOC + SPOC + 翻转课堂”的“数字信号处理”课程教学改革研究
A Research on the Mixed Teaching Mode of “Digital Signal Processing” Based on “MOOC + SPOC + Flipped Classroom”

未来教育教学将充分利用网络化平台和智能教育等先进信息技术汇聚各类优质教学资源，实现学生的探究式、主动式、渐进式学习过程和能力的培养。本文应用MOOC、SPOC和翻转课堂对“数字信号处理”课程采用线上线下混合式教学模式进行了实践探究。MOOC课程选用中国大学MOOC国家精品课程；异步SPOC课程补充相应的教学资源，公布课程教学日历，明确学生应学习的内容以及学习要求；线下课堂精讲课程的重要知识点、难点，组织学生深入研讨并且演示各自的项目成果。经过实践，这种结合网络在线学习和翻转课堂环节的混合式教学，在教学中发挥了积极作用，取得了较好的效果，但仍需要进行更为深入的实践与总结提高。
With the deep development and wide popularization of the internet, in the future, education and teaching will make full use of advanced information technology such as network platform and intelligent education to combine all kinds of high-quality teaching resources, so as to realize stu-dents’ exploratory, active and progressive learning process and ability cultivation. This paper summarizes the process of online and offline mixed teaching reform of Digital Signal Processing course based on “MOOC + SPOC + Flipped classroom”. Students learn on MOOC and SPOC online and enhance learning through flipped class. This teaching mode is student-centered, which helps to improve their ability of solving practical engineering problems. However, deeper practices and summary improvements are still needed to carry on.
