微课已成为信息时代重要的教学资源,为实现信息技术与课程深度融合提供了思路。目前国内关于微课的研究主要集中在微课的基本理论及教学应用研究上,而在技术层面,关于微课的设计与开发方面的研究相对缺乏。本研究针对PPT动画类微课进行如下研究:剖析了PPT动画类微课的概念、特征、制作原则,构建并重点阐释了该类微课的设计与开发模型,并以该模型为依据设计开发了《加涅的九段教学法》微课,以期为更好地设计与开发较高水平的微课提供借鉴,进一步推动我国微课研究的快速发展。
Micro-lecture has become important teaching resources of the information age and provided a train of thought to realize deep integration of information technology and curriculum. The present domestic research on micro-lecture mainly focuses on its elementary theories and teaching application,while the research on the design and development of micro-lecture is relatively short.This paper has done the following research on PowerPoint animation.Firstly,it analyses the concept,characteristics and principles in making such micro-lecture.And then,the research constructs and emphatically explains the model of its design and development.Finally,according to this model,the author has designed and developed the micro-lecture of "Gagne' s nine-step teaching method" ,hoping to provide references for designing and developing rather high level' s micro-lecture and further promote the rapid development of the research on micro-lecture in China.
