基于“先音后画五步录制法”的微课设计与开发--以《手机升格与降格视频的拍摄》为例

Design and Development of Micro-course Based on the“Five-step Sound Recording Method Before Frame”:Take“Mobile Phone Upgrading and Downgrading Video Shooting”as an Example

微课作为一种“短小精悍”的新型教学资源,符合当今碎片化学习和移动学习的时代特征,深受数字化时代学习者的青睐。但是,由于教师设计理念和理论、技术使用、知识点组织不合理等问题,导致微课达不到预定的教育教学效果。基于此,以微课《手机升格与降格视频的拍摄》为例,从撰写解说词、课件可视化、录制解说词、录制课件画面、音画合成与后期等步骤出发,提出了“先音后画五步录制法”的微课设计与开发的新方法,为广大的微课设计与开发者提供一种新开发思路。

As a new type of teaching resource both short and powerful,micro-courses are in line with the characteristics of today's fragmented learning and mobile learning,and are deeply favored by learners in the digital age.However,due to misunderstandings on teaching design concepts and theories,technology,and unreasonable organization of knowledge points,micro-class fails to achieve the intended educational and teaching effects.Based on this,taking the micro-class titled“Mobile Phone Upgrading and Downgrading Video Shooting”as an example,one could follow the steps from rundown creation,PPT visualization,rundown recording,PPT screen recording,audio-visual combination,and post-editing,it puts forward the philosophy of“sound comes first,pictures come the second”.The“five-step recording method”is a new method of micro-course design and development,which provides a new development idea for the majority of micro-course designers and developers.
