本文结合教学实际,就如何在初中数学教学中合理应用多媒体技术作了大胆的探索.一、创设情境,激发学生的学习兴趣在初中数学教学中采用多媒体教育技术,能给学生提供实物图像、运动过程,并且利用放大、重复和定格特技手段使教学内容丰富多彩、形象直观,成功创设了学生喜闻乐见的的教学氛围,从而有效激发了学生自主探究的兴趣.譬如,我在执教“三角形内角和定理”时,先让学生通过剪纸、拼接和度量的方法让学生直观感受新知识,接着利用几何画板随意画一个三角形,测量出它的三个内角并求和,然后鼠标移动三角形的顶点
In this paper, teaching practice, how to make rational use of multimedia technology in junior high school mathematics made a bold exploration.First, the creation of situations to stimulate students interest in learning mathematics teaching in junior high school multimedia education technology, to provide students with physical images, sports Process, and use magnifying, repeating and fixed stunt techniques make the teaching content rich and colorful, the image is visual, successfully created the teaching atmosphere loved by students, which effectively stimulated the students to explore the interest of independent research.For example, I was teaching “triangle angle and Theorem ”, let students intuitively learn new knowledge through paper-cutting, stitching and measuring methods, and then use the geometric drawing board to draw a triangle arbitrarily, measure its three internal angles and summation, and then move the vertex of the triangle
