数学是一门研究数量关系和空间形式的科学,具有别具一格的公式结构、严密的数学符号体系、抽象的数学语言、形象的图形,对于培养小学生数学思维的严谨性具有无可替代的作用。[1]一个人的思维习惯是从小养成的,所以数学教师要培养小学生的数学思维的严谨性,需要从小学生抓起。本文在教学实践中总结出:巧用数学概念,引领学生通过理解概念实质感知数学的严谨性、巧用四则运算举一反三,在验证中培养学生严谨的数学思维、巧用一题多解与数形结合的方法,在尝试中培养学生严谨的思维这三种教学方法,并取得了良好的教学效果。
Mathematics is a science that studies quantity relations and space forms. It has a unique formula structure. The strict mathematical symbology, abstract math language and image of the figure have an irreplaceable effect on cultivating the rigor of primary school students’ mathematical thinking. [1] A person’s habit of thinking is developed from childhood, so mathematics teachers to train pupils to rigor of mathematical thinking, need to start from the pupils. This paper summarizes in the teaching practice: clever use of mathematical concepts, leading students through the understanding of the essence of the concept of rigor of mathematics, skillfully use the four operations from top to bottom, in the training of students rigorous mathematical thinking, clever use of a multi-solution and the number of forms A combination of methods, trying to train students rigorous thinking of these three teaching methods, and achieved good teaching results.
