摘要:本文在文献研究和分析的基础上,结合自身学习及教学实践,从小学数学课堂切入,尝试论述以下问题:一是小学数学课堂中情境创设运用的现状与反思;二是小学数学教学中情境创设的多样化运用,具体分为创设数学化的生活情境、描绘有趣的故事情境、设计开放的游戏情境、展开具体的操作情境四种情境创设方法进行论述。通过研究,论文旨在指出情境创设这一教学方法在教学实际运用中易形成的误区,并丰富充实小学数学教学中情境创设的运用方法。

Abstract:This paper is based on literature research and analysis, and with the combination of my own learning and teaching practice in the primary mathematics class,I try to discuss the following issues. One is on the current situation and rethink of the application of situation creation in Mathematics class of elementary school. The other is on the diversified application of situation creation in Mathematics teaching including mathematical living situation, interesting described story situation, permissive game situation and concrete operate situation. Through the research, the writer is aimed at pointing out the easily formed misunderstanding of situation creation in Mathematics teaching, at the same time, enriching the methods of how to create teaching situation in Mathematics teaching of elementary school.

实践证明,把情境教学运用到小学数学课堂教学中,确实会对学生学习产生积极的影响。通过有效、多样化的情境创设,会让学生的课堂积极性被调动起来,也会使学生的数学思维更加活跃。在选择是否要创设情境或创设什么样的情境时,要注意以该情境是否能够很好地承载数学知识点、是否能够达到本课的教学目标作为标准。只有适时的在不同情况下采用不同类型的情境创设法,才能很好地促进学生数学知识、数学能力、数学思维和数学体验的全面和谐发展。但在此基础上,我们也要强调一个问题,就是防止数学课堂上对数学本质的一种淡化和忽略,即我们要关注多样化创设情境下,情境的“数学化”问题。在创设多样化情境的过程中,如何做到剔除情境的干扰因素,从而将情境“数学化”,这是在以后的教学和研究中要继续深入分析和思考的另一个问题。
