数学运算是小学数学教学的重要组成部分.运算错误屡屡发生是学生学习中普遍存在的问题.对运算错误进行分析,不仅可以使教师了解学生产生错误的原因,有针对性地预防和矫正,而且能够使教师掌握运算过程的心理规律,同时更是实施素质教育的需要.由于产生运算错误原因的复杂性和错误的表现形式的多样性,对运算错误进行分类是比较困难的.本文对学生运算过程中的障碍及教学对策进行初步分析和探讨.1.运算法则不理解掌握运算法则是学生进行正确计算的基础,学生若对运算法则不能真正理解,也就不可能应用它来正确地进行计算.
Mathematical operation is an important part of mathematics teaching in primary school.Most occurrence of arithmetic errors is a ubiquitous problem in students ’learning.On the basis of analyzing arithmetic errors, teachers can not only understand the reasons of students’ mistakes, but also prevent and correct them in a targeted manner Can make the teacher grasp the psychology law of the operation process, moreover it is the need of carrying out the quality education at the same time.Because of the complexity of the reason that causes the operation error and the diversity of the wrong manifestation, it is difficult to classify the operation error.This paper analyzes the student operation Process obstacles and teaching strategies for a preliminary analysis and discussion.1 algorithms do not understand the master algorithm is the basis for the correct calculation of students, if the students can not really understand the algorithm, it is impossible to apply it to correctly calculate .
