【Abstract】With the rapid development of digitization,multimedia technology teaching has been widely used in primary school mathematics and geometry teaching,and has gradually developed into an indispensable auxiliary means.The use of multimedia technology in geometry teaching is conducive to comprehensively carry out the cultivation of core literacy,improve classroom enthusiasm,break through key and difficult points,cultivate students' ability to think and solve problems independently,and reflect high application value.In the actual teaching work,in order to further strengthen the effective application of multimedia technology in primary school mathematical geometry teaching,the education department first needs to increase publicity and encourage teachers to actively use multimedia technology.Teachers can use multimedia technology to create scenes and stimulate pupils' interest in learning.During the lecture,a graphic presentation will be conducted to directly hit the essence of the problem.Change static into dynamic and simplify the content of the textbook.

多媒体技术教学是指在教学过程中,运用多媒体设备,根据教学目标和学生的特点,将课堂知识点以图像、动画、声音、文字等方式展现出来,并与传统教学模式相结合,是传统教学手段的重要辅助教学方法。目前在很多小学数学课堂上,尤其是几何教学过程中,多媒体技术多有运用,可以帮助小学生直观了解几何知识点,有助于空间思维能力的构建。多媒体教学并不仅仅是用多媒体技术来展开教学工作,把课本内容用多媒体设备呈现。新课程改革的背景下对多媒体技术教学提出了更高的要求,更加强调运用的有效性。本文结合多媒体技术在小学数学几何教学工作中的情况进行简要分析,提出相关有效运用建议,以期为今后多媒体技术在小学数学几何教学的有效运用提供一定的参考和借鉴。……
