摘 要

本文是现代多媒体教育技术应用于小学数学几何教学，用多媒体的虚拟直观性，将抽象的图形直观的展示在多媒体上，充分发挥多媒体的教学优势，激发学生几何学习兴趣，促进学生空间观念发展，提高课堂效率，改变课堂枯燥的教学氛围。本文从从空间思维发展与学习特点、新课标对小学几何知识的解读、以及小学几何的知识整合，来分析小学几何的重难点，学生的思维情况，继而运用问卷调查的研究方法得出教师利用多媒体教学有助于提高课堂的效率，激发学生对几何学习的兴趣，将传统的教学模式与多媒体教学模式想结合，改变单一的教学模式。但教师在使用多媒体时要注意时间的控制和展示内容的控制，要合理的运用多媒体这一工具。最后通过课例圆柱的体积，来研究多媒体在数学课堂应用的情况。得出多媒体在几何课堂的应用使得几何课堂变得更加的省事，利用多媒体教学课堂的互动氛围良好，学生能够集中注意力，学生会更加的有兴趣进行几何学习，同时教学效果良好，体现出多媒体的价值。

Abstract

This article is the modern multimedia education technology application elementary mathematical geometry teaching, using multimedia virtual visual,the abstract graphics intuitive display on multimedia,give full play to the advantages of multimedia teaching, stimulate students geometry to study the interest, promote the development of the students' space concept, improve the classroom efficiency and change the boring classroom teaching atmosphere.This paper from the development of spatial thinking and learning characteristic,the interpretation of knowledge of the English curriculum of elementary geometry, and elementary geometry knowledge integration,to analyze the difficult point of elementary geometry, the minds of students, and then USES the method of questionnaire research concludes that teachers use multimedia teaching is helpful to improve the efficiency of the classroom, stimulate students interest in learning geometry, Combine the traditional teaching mode with the multimedia teaching mode to change the single teaching mode.However, teachers should pay attention to the control of time and content when using multimedia, and make reasonable use of multimedia as a tool.Finally, the volume of the cylinder is used to study the application of multimedia in mathematics classroom.It is concluded that the application of multimedia in geometry class makes the geometry class more convenient. The interactive atmosphere of using multimedia teaching in the class is good.Students can concentrate their attention,and they are more interested in learning geometry.
