【摘 要】小学数学的教学过程中许多教学内容均与学生的日常生活实际有着紧密的关联。因此,利用生活情境教学方式对小学数学课程进行开展,不仅有利于教师提高教学效率,同时能促使学生联系身边实际生活,对抽象化的数学概念进行更加深刻的理解和吸收,并且将教材上的理论知识有效运用至实际生活中。本文将以联系生活实际进行情境创设、以游戏形式进行情境创设、运用多媒体技术进行情境创设、营造良好课堂气氛、组织情境教学活动和设置开放性问题等方式对小学数学中生活情境的运用做具体分析。

【Abstract】Many teaching contents in the teaching process of elementary school mathematics are closely related to the actual daily life of students. Therefore, the use of life context teaching methods to carry out elementary school mathematics courses not only helps teachers improve teaching efficiency, but also encourages students to connect with the real life around them, to have a deeper understanding and absorption of abstract mathematical concepts, and to integrate the teaching materials. The theoretical knowledge is effectively used in real life. This article will use the actual situation of life to create situations, to create situations in the form of games, to use multimedia technology to create situations, to create a good classroom atmosphere, to organize situational teaching activities, and to set up open questions to make specific use of life situations in elementary school mathematics. analysis.

一、聯系生活实际进行情境创设
小学数学的学习内容主要源于生活中,因此,教师在教学过程中有效联系生活实际进行情境创设可激发学生的好奇心和学习兴趣。例如,在教学“平行四边形和梯形”一课时,在学生了解到“平行四边形和梯形都是四边形”“平行四边形和梯形都有对边平行”等共同特点之后,教师可为学生呈现学校或者家中的平面情景图,引导学生在图片中找到平行四边形和梯形的存在,进而让他们从身边实物中寻找这两种图形,或者指导学生利用铅笔小棍等身边常用物品分别摆出平行四边形和梯形。教师在引导学生动手实践和联系实际生活进行数学情境学习的过程中,可以促使他们加深对知识的理解和吸收,达到教学效果最大化的目标。……
