视频微课的实用学分析

Pragmatic Analysis on Video Micro-lessons

近两年，视频微课正逐步成为教育改革和教育信息化发展的新议题，被应用于多种教育情境中，为信息技术进课堂、信息技术与课程的深度融合以及信息技术对教学方式的改变提供抓手。本研究旨在从实用学视角，通过分析视频微课的常见应用情境，关注视频微课的效用，以揭示视频微课设计开发与应用之间的关系，加强微课设计与应用情境间的对话。本研究首先分析了目前微课设计与应用存在的问题及局限性，然后引入实用与语用的思想，对视频微课的常见应用情境进行了分析，澄清了它与传统课件在设计与应用方面关注点上的不同，之后在综合分析的基础上提出了视频微课的应用模型以及视频微课设计与应用的关系图。

In recent years， video micro lessons have attracted great interest and attention from teachers and administrators because of their short time， small capacity， low threshold technology and other kind of characteristics. Up to now， they have been used in a variety of educational situations， such as before class for study preparation， in class for key and difficult knowledge explanation， after-school review， online learning (such as Massive Online Open Courses - MOOCs)， mobile learning， and flipped classroom， etc. Generally speaking， video micro-lessons are designed for a certain context， but objectives and results are different. The purpose of this study is， from a pragmatic perspective， to reveal the relationship between the design and implementation of the video micro-lessons so as to strengthen the connection between the design and implementation and maximize the outcomes. The study first analyzed the problems and limitations existing in the design and implementation of the video micro-lessons， and then from the pragmatic perspectives， analyzed the common application scenarios， clarifying that they are different from traditional courseware in the design and implementation concerns. Finally， on the basis of comprehensive analysis， the authors propose an implementation model for the video micro-lessons. The authors also provides enlightenment for the design of adaptive search engine and personalized learning.
