在数学教学中运用多媒体，有其广阔的天地，能取得意想不到的教学效果。因而多媒体教学深受老师和学生的喜欢。运用多媒体教学，能使抽象的数学问题具体化。有些数学知识比较抽象，特别是几何知识，学生很难理解，而运用多媒体，可使难点分解成具体的图象，化难为易，教学效果
The use of multimedia in mathematics teaching has its vast world and can achieve unexpected teaching effects. Therefore, multimedia teaching is deeply loved by teachers and students. The use of multimedia teaching can make abstract mathematic problems concrete. Some mathematics knowledge is relatively abstract, especially geometric knowledge, which is difficult for students to understand. The use of multimedia can make it difficult to break down into specific images.
