小学教育-小学数学分数运算教学策略研究——以宿迁市宿城区某小学为例论文

小学数学分数运算教学策略研究———以宿迁市宿城区某小学为例摘要 分数是小学数学学习阶段的一个重点和难点，是数学知识的重要组成部分，也是小学生对数的一次拓展性学习；它与整数和小数之间都有紧密的联系，体现了丰富的数学思维，对于培养学生的数感也起到了十分重要的作用。其中分数运算能力的高低对学生学习后续其他内容有着直接的影响，因而这一阶段数学教学中亟待解决的难题是提高学生的分数运算水平，且合理教学策略的运用有利于学生分数运算知识的学习和教师教学效果的优化。本文主要运用观察法、调查法和访谈法，以宿迁市宿城区某小学中、高年级数学教师和五、六年级学生为调查对象，结合两者的实际情况对小学数学分数运算教学现状展开研究。研究结论表明：教师教学过程略显粗糙且手段单一、分数运算教学内容和生活实际联系少、教师缺少对数学思想方法的渗透、学生分数运算错误率高。笔者通过对研究中发现的问题进行分析以及论述不同教学实践所呈现的教学效果，得出以下几点小学数学分数运算教学策略：丰富教师知识素养，提高专业水平；加强直观教学，优化教学过程；创设不同情境，密切联系生活；打好扎实基础，培养良好的数学习惯。关键词 小学数学 分数运算 教学策略 The study on the teaching strategy of elementary mathematics grade operation —Taking a primary school in Sucheng District of Suqian as an exampleAbstract Fraction is a key and difficult point in primary school mathematics learning, it is an important part of mathematics knowledge, but also a logarithmic extension of learning for pupils; It is closely related to integer and decimal, embodies rich mathematical thinking, and plays a very important role in cultivating students' sense of number. Among them, the ability of score operation has a direct impact on other contents of students' learning, so the problem to be solved in this stage of mathematics teaching is to improve the level of score operation of students, and the use of reasonable teaching strategies is conducive to the learning of students' score operation knowledge and the optimiza...
