【摘 要】在小学数学教学中采用生活化模式,意义是多元的,可提升学习效率、培养学生实践素养、训练学生创新思维,还可提升学生学习兴趣。当下,生活化教学在教育实践中得到普遍运用,但还存在着一些问题需要改进和优化。笔者认为,教师应充分考虑学生的学情,在内容、过程、形式等方面进行综合把握,以保证生活化教学充分、优质地发挥其效能。

【Abstract】Using a life-oriented model in elementary school mathematics teaching has multiple meanings. It can improve learning efficiency, cultivate students' practical literacy, train students' innovative thinking, and enhance students' interest in learning. At present, life-oriented teaching is widely used in educational practice, but there are still some problems that need to be improved and optimized. The author believes that teachers should give full consideration to the students' academic conditions, and comprehensively grasp the content, process, and form in order to ensure that the life-oriented teaching is adequate and quality to play its effectiveness.

一、生活化教学的价值
(一)提升学习质效
生活化教学将教学活动置于现实生活背景中,因此,其具有很强的形象直观、生动具象的特征。而小学生的学习思维是明显偏向于直观的,也就是他们的学习认知、记忆,多是以观察、体验、操作等直观的方式完成。可见,生活化教学与小学生的认知规律相符,可提升学习实效。如,教学四年级“方向与位置”(方向和距离)时,如果教师向学生展示“去图书馆”的方位图,表面是直观,但其实是几何抽象问题,学生理解起来很费力。而如换个场景,把学校平面图展示出来,围绕“从教室到英语老师办公室怎么走?”进行教学,学生则很容易将“地图”与生活经验关联起来,从而快速理解知识。
(二)培养实践素养
学习数学的最终目标,是让学生能用數学知识去服务生活实践。而显然,培养学生的数学实践素养(实践意识和实践能力),最好的办法就是让学生参与实践、体验实践,将他们放在实践场景中去,让学生以实践的思维进行学习。……
