数学知识的教学本身是比较抽象的,因此教师需要运用多媒体对数学知识进行演示,加强信息技术与数学课程的“整合”。那么,数学课如何用好多媒体,使数学知识变抽象为具体,从而引导学生去探索数学知识的奥妙呢?笔者认为要抡好“三板斧”。一、动态演示,发展学生空间想象力数学知识比较抽象,往往使学生感到枯燥乏味,而计算机多媒体则能将静态的数学知识动态化,激发学生的学习兴趣,加深对数学知识的理 Teaching of mathematical knowledge is rather abstract in itself, so teachers need to use multimedia to demonstrate mathematical knowledge and strengthen the “integration” of information technology and mathematics courses. So, how to make good use of multi-media math class mathematics knowledge abstraction as a concrete, so as to guide students to explore the mystery of mathematical knowledge? I think to be good, “three ax.” First, the dynamic demonstration of the development of students ’space imagination Mathematics is more abstract, often make students feel boring, while the computer multimedia can static dynamic knowledge of mathematics to stimulate students’ interest in learning and deepen their understanding of mathematical knowledge
