教育心理学研究表明:人获取的外界信息中,83%来自视觉,11%来自听觉,3.5%来自嗅觉,1.5%来自触觉,1%来自味觉。显然增加视觉、听觉信息量是获取更多信息最可取的方法。而多媒体教学恰恰在视觉、听觉效果方面有其独特的优势。所以,从教育心理学角度看,运用多媒体教学对提高数学课堂实效大有裨益,其突出的作用正在逐步被人们认识、理解、接受和应用。下面,本人结合多年的教学实践谈几点看法:
Educational psychology studies show that 83% of the external information obtained by humans is from vision, 11% from hearing, 3.5% from sense of smell, 1.5% from touch, and 1% from taste. Obviously increase the visual and auditory information is the most desirable way to get more information. The multimedia teaching just in visual and auditory effects have their unique advantages. Therefore, from educational psychology point of view, the use of multimedia teaching is of great benefit to improve the effectiveness of mathematics classroom. Its prominent role is gradually being recognized, understood, accepted and applied by people. Below, I combine years of teaching practice to talk about several points:
