由于科技的迅猛发展,微课作为一个新词被提出,微课技术也被越来越多的人熟知并接受。微课的主要呈现方式是视频,它综合使用了多种多媒体手段,围绕知识的重难点,从学生的角度出发,针对某个疑难点进行详细分析讲解。近年来,将微课技术引入教学活动中的例子更是不胜枚举,它的出现,改变了传统单一的教学模式,对现代教育方式的改革具有划时代的意义。微课技术的突出特点就是教学时间短、主题明确、内容精炼,对教学活动起到极大的辅助作用。本文笔者将阐述微课的主要优势以及微课在初中数学课堂中的运用,强调在教学活动的不同阶段如何与微课技术进行完美的结合,从而提升课堂实效性,推动教育的深化改革。 Due to the rapid development of science and technology, micro-class as a new word was proposed, micro-class technology has also been more and more people are well-known and accepted. Micro-class is the main presentation of video, which uses a variety of integrated multimedia tools, focusing on the knowledge of the difficult, from a student’s point of view, a detailed analysis of a difficult point to explain. In recent years, examples of introducing micro-class technology into teaching activities are numerous. Its appearance has changed the traditional single teaching model and has epoch-making significance for the reform of modern educational methods. The outstanding features of micro-class technology is the short teaching time, a clear theme, content refining, teaching activities play a great supporting role. In this paper, I will explain the main advantages of micro-class and the use of micro-class in the junior high school mathematics classroom, emphasizing how to combine the micro-class technology perfectly in different stages of teaching activities so as to improve the effectiveness of the class and promote the deepening reform of education.
