多媒体给教学带来最直观的“效益”就在于,它能够将知识以学生最能接受的形式呈现出来,并于无形之中使课堂容量增大。高中数学典型的集“数形关系”于一体的学科特点,一直以来都让很多高中生心生畏惧,也成为很多高中生顺利通过高考的“拦路虎”。但多媒体可以有效改变这一现状,它的先进性,以及灵活快速性和大容量、可控制以及交互性,恰恰可以降低高中数学的难度。尤其是微视频技术的介入,突破了课堂与教材对学生思维造成的局限,让他们在有限的空间也 The most intuitive “benefit” that multimedia brings to teaching is that it can present knowledge in the form that students are most receptive to and increase the capacity of the classroom invisibly. High school mathematics typical set “number of relations ” in one of the characteristics of the discipline, has so many students feel very dizzy, but also become a lot of high school students passed the college entrance examination “stumbling block.” But multimedia can effectively change the status quo, its advanced nature, as well as the flexibility and speed, large capacity, controllability and interactivity, just can reduce the difficulty of high school mathematics. In particular, the involvement of micro-video technology, breaking the classroom and textbooks caused by the limitations of student thinking, so that they also have limited space
