【摘 要】数学是一门出现两极分化现象比较严重的学科,小学生在学习数学过程中,如果一开始基础就没有打牢,或者对数字不敏感,那么在接下来的学习中容易出现大面积的知识断层现象,年级越高,两极分化越明显。提升中年级小学生在学习数学过程中解决问题的能力,值得每一位数学教师为之付出努力。本文以小学中年级数学“解决问题”能力提升的教学思考为视角展开论述,提出以下几点措施。

【Abstract】Mathematics is a subject with serious polarization. In the process of learning mathematics, if elementary school students do not lay a solid foundation at the beginning or are not sensitive to numbers, then a large area of knowledge gaps are likely to occur in the subsequent learning. , The higher the grade, the more obvious the polarization. It is worth every mathematics teachers efforts to improve the problem-solving ability of middle-grade pupils in the process of learning mathematics. This article discusses from the perspective of teaching thinking on the improvement of mathematics "problem solving" ability in middle grade primary school, and proposes the following measures.

一、小学中年级学习数学出现的问题
(一)对知识的理解度不够
小学中年级学生上课容易走神,听课只听一个表面就认为自己什么都会了,不再往深处去学习,自满心理也比较严重。这个阶段的孩子,往往会被浅显的知识点迷惑。这就导致教师讲过的知识对于他们来说只是一知半解,并没有掌握课堂重点,那么在今后的复习和做题过程中也就出现了各种各样的错误。
(二)解题思路混乱,不能把握问题关键
数学是一门连贯性很强的学科,解题思路要符合逻辑性,要懂得举一反三。然而,小学中年级学生在解题过程中往往缺乏耐心,不去探究就把答题过程写了下来。这样做题速度是很快,但往往结果是错误的,因此想提高数学成绩很难。
数学的教学具有抽象思维,教师的表述稍有偏差,就会将学生引向错误的解题思路。教师备课的严谨程度,决定学生对关键部分的掌握程度。……
