基于学习元平台的微课设计

Design of Micro － lecture Based on Learning Cell System

微课已成为当前教育领域研究的一大热点，受到越来越多学者的关注。本文通过微课的各种定义，分析了微课认识的误区，指出微课的本质是“课”，并从“课”的角度提出，微课是在微型资源的基础上附加教学服务的小型化课程，由微型资源、学习活动、学习评价和认证服务四部分构成。此外，由于微课小而散，应通过语义技术描述微课间的整体知识逻辑，实现散而有序。在此基础之上，本文介绍了基于学习元的微课设计思路，包括微课设计、教学信息描述、微课聚合和开发模式等，试图为研究者和设计者们提供参考。

Micro － lecture has become a hot research point in education，which attracts more and more attention fromscholars． This paper analyzes the current various definitions of micro － lecture，revealing people＇s misunderstanding ofmicro － lecture，pointing out that the nature of micro － lecture is ＂ lesson＂ ． From this point，micro － lecture is micro－ lesson based on micro － resources with additional teaching service，which consists of four parts: micro resources，learning activities，learning assessment and certification services． Besides，micro － lecture is small and scattered，sothe overall knowledge logic between micro － lectures should be described by semantic technology to keep micro － lectureorganized． On this basis，this paper gives the introduction to micro － lecture design based on learning cell system，includingmicro － lecture planning，teaching information description，micro － lecture aggregation and development patterns，etc． ，trying to provide ideas and reference for micro － lecture researchers and designers．
