                          小学数学课堂教学改进中多媒体技术的应用

                          时间:2019-02-27 11:30作者:徐国安
                          本文导读:这是一篇关于小学数学课堂教学改进中多媒体技术的应用的文章,当前,学校的各门学科都会采用多媒体辅助教学的形式,均取得了不错的效果。尤其是在小学阶段,多媒体教学凭着声像、图文并茂的特点,更是深深地吸引了小学生的注意力。然而并非所有教师都能够恰当地运用多媒体,最大

                            摘    要: 多媒体在小学数学教学中的恰当运用,不仅能够抓住小学生的眼球,吸引学生的关注,还能够拓宽学生视野,增大课堂容量,以直观形象的教学,提高数学教学的效率。但是如果运用不恰当,不仅无法充分发挥多媒体的作用,还会适得其反。为此,探讨多媒体在小学数学教学中的恰当运用非常关键,也非常有必要。

                            一、借助多媒体为学生创设教学情境

                            二、借助多媒体使学生切实感受知识的形成过程

                            就小学数学课堂教学而言,低年级学生由于知识的理解力与内化能力存在明显的不足,所以教师不能过于注重课本教材的分析和讲解,而是要注重如何将新知识的由来变得更加生动形象,让新知识真正能够被学生所理解、所掌握、所应用,使学生切实感受知识的形成过程,课堂教学的氛围与效果才能更加理想。然而,教师只是注重用课本内容让学生明白所要学的知识,那么学生在知识的理解上必然会存在一定的困难,由于始终存在不解的状态下,课堂教学氛围依然会以“安静”为主要特征,学生与教师之间自然也很难形成互动,久而久之学生就会产生抵触的情绪和心理。为此,在燃起学生学习的欲望过程中,教师要设法让所要学习的内容动起来,先让学生知其然,再让学生知其所以然。这样,学生学习的激情也会随之产生,并变得越来越浓烈,多媒体教学无疑是最为直接的途径。以“圆的认识”教学为例,在多媒体课件的制作过程中,我将圆规画圆的动态过程添加到课堂的基本部分之中,让处于静止状态的课本内容变得更加生动、活灵活现,这不仅有助于学生了解画圆的过程,同时还有助于学生课堂的注意力高度集中。再以“圆的面积”教学为例,让学生掌握如何计算无疑是重中之重。我在教学过程中,将其推导过程置于PPT中,让学生通过圆的平均分理解为什么圆的面积公式为πr2,进而通过动态推导过程帮助学生打消心中的疑惑与不解,让学生的印象能够更加深刻,这显然也是以往传统的“授受式”教学所不能达到的。通过以上教学实例,不难看出多媒体教学设备不仅仅是教师有效开展教学的得力助手,同时也是帮助学生理解、接受、掌握、应用新知识最为有效的平台,知识结构的形成过程也由此变得更加直观化,教师“教”与学生“学”的成果也势必会更加趋向于理想化。

                            三、借助信息技术,为学生还原知识于生活

                            四、关注并改进小学数学课堂教学运用多媒体存在的问题

                            (一)课件过多,演示与板书过少,教师的教学基本功无法得到训练

                            (二)课件播放占主要地位,师生互动变少

                            (三)课件制作花哨,学生注意力过多集中在课件的图片与视频中,分散精力
