多媒体教学越来越多地受到学生和教师的欢迎。教学中教师难以表达、学生难以理解的抽象内容、复杂的变化过程、细微的结构等,利用多媒体通过动画模拟、局部放大、过程演示等手段都能予以解决。以下,我以初中地理《中国的河流和湖泊》一章为例,谈谈运用多媒体在优化地理教学中的 Multimedia teaching is increasingly welcomed by students and teachers. In the teaching, it is difficult for the teacher to express, the abstract content that the student has difficulty to understand, the complicated change process, and the subtle structure. It can be solved by means of multimedia through animation simulation, local amplification, and process demonstration. In the following, I took the junior school geography “China’s Rivers and Lakes” chapter as an example to discuss the use of multimedia in the optimization of geography teaching.
