多媒体一般理解为多种媒体的综合,它是计算机和视频技术的结合,实际上它是两个媒体;声音和图像。反映到数学课上,常用到的媒体工具有大屏幕电视、计算机、实物投影等。近几年来,多媒体教学设备也走进了农村学校的教室,它的应用日益广泛,下面我谈几点有关多媒体教学在数学课堂上的作用的看法。1.使用多媒体时要注意把握好度。从老师们自制的课件和从网上发布的一些课件来看,其内容和课本大同小异,差别不大。如果我们一味地把课本中的知识点、例题和练习题都搬到幻灯片中去,其意义不大,有时甚至会出现反作用。
Multimedia is generally understood as a combination of multiple media, it is a combination of computer and video technology, in fact it is two media; sound and image. Reflected in math class, commonly used media tools are large-screen TVs, computers, in-kind projection and so on. In recent years, multimedia teaching equipment has also entered the classrooms of rural schools, its application is increasingly widespread, let me talk a few points about the role of multimedia teaching in the classroom. 1. When using multimedia should pay attention to grasp the degree. Home-made courseware from teachers and some of the courseware released from the Internet point of view, its content and textbooks are similar, not very different. If we blindly put the knowledge of the textbooks, examples and exercises are moved to the slide, it is of little significance, and sometimes even counterproductive.
