随着近年来移动智能终端技术的飞速发展,泛在学习有了更为坚实的技术支持,而微课正是这种泛在学习的体现。微课聚焦重、难点,可以让学生反复观看,在一定程度上减少了教师在课堂上对重、难点的反复讲解。通过分析微课产生的背景,在对微课、慕课等容易混淆的概念及特点进行分析与界定的基础上,构建了一个微课的开发模式,该模式由前期准备模块、内容分割模块及微课应用模块等六个部分共同组成。以内容分割和微课应用这两个模块为核心,对C语言中最难理解的循环结构进行具体阐述,分析如何运用该模式进行微课的开发。
With the rapid development of mobile intelligent terminal technology in recent years, u-learning has a more solid technical support,micro-lecture is the embodiment of this kind of u-learning. Micro-lectures focus on important and difficult learning points,and students can watch the lectures over and over again.Therefore,it to a certain extent saves the teachers' time in the classroom to repeatedly explain the important and difficult points.Through the analysis of the background of the micro-lecture,and based on the analysis and definition of the confusing concepts of micro-lecture and Mooc as well as their features,a development model of micro-lecture is constructed.The model is comprised of six integrated parts,the pre-preparation module, the content segmentation module and the micro-lecture application module,to name just a few.Taking the content segmentation module and the micro-lecture application module as the cores,this study specifically elaborates on the most difficult loop structure of the C language,meanwhile,it also analyzes how to use this model to develop micro- lectures.
