作为一种新型的教育形式和现代化教学手段的多媒体技术,由于其具有强大的信息处理和交互控制功能,因此,它是广大的数学教师进行课堂教学改革有力的辅助教学工具。利用多媒体技术,能将文字、图形、图像、音频、视频、动画等信息进行有机地结合与综合地处理,并可以对各信息进行交互控制。使枯燥无味的教学内容变得图文并茂、有声有色、生动有趣,把一些抽象而难以理解的教学内容,形象而直观地表达出来,使学生容易接受和理解。利用多媒体强大的交互功能,让学生主动参与,充分发挥学生的主体作用,大大提高了学生的学习兴趣和学习主动性,为学生创造出一种轻松活泼的学习氛围,可以使学生乐在其中,减轻了学生的学习负担,大大提高了课堂教学效率和教学效果。一、运用多媒体,有效提高学生思想品德素质利用现代教育技术,抓住时机,对学生进行爱国主义教育。例如:在多边形教学课中,将五星红旗上的五角星投影出来,都是些美丽的几何图案,让同学们知道祖国不但繁荣昌盛,就连 As a new form of education and modern teaching methods of multimedia technology, because of its powerful information processing and interactive control functions, it is the majority of mathematics teachers in teaching reform is a powerful auxiliary teaching tool. The use of multimedia technology, can text, graphics, images, audio, video, animation and other information to organically combine and comprehensively deal with, and each information can be interactive control. So boring teaching content become illustrated, vivid and interesting, vivid and interesting, some abstract and difficult to understand the teaching content, visual and intuitive expression, so that students can easily accept and understand. The use of powerful multimedia interactive features, so that students take the initiative to participate in, give full play to the role of students, greatly improving the students’ interest in learning and learning initiative for students to create a relaxed and lively learning atmosphere that students can enjoy themselves, Reduce the burden on students’ learning, greatly improve the efficiency of classroom teaching and teaching effectiveness. First, the use of multimedia, and effectively improve the quality of students’ ideological and moral quality of modern educational technology, seize the opportunity to carry out patriotic education for students. For example, in the teaching of polygons, projecting the five-pointed stars on the five-star red flag are all beautiful geometric patterns that let students know that the motherland not only prospered, but also
