一、影响小学计算的因素从事小学数学教学工作已有十多年了,一直被孩子们的计算不准而困扰。通过问卷、测试,得出影响学生计算准确率及速度的因素有以下几点:1.算法和算理不明经调查,有10%左右的学生出现计算错误是由于对算法和算理不明确。2.轻视口算和估算《义务教育数学课程标准》明确提出“应重视口算,加强估算”。虽然许多教师知道口算、估算的重要性,但部分教师被动地
First, the factors affecting the calculation of primary Mathematics engaged in primary school mathematics teaching has been more than 10 years, has been the calculation of the children are not allowed and troubled. Through questionnaires and tests, the factors that affect the accuracy and speed of students ’calculation are as follows: 1. The algorithm and arithmetic are unknown After investigation, about 10% of students’ calculation errors are due to the unclear algorithms and algorithms. 2. Slight accounting and estimates “compulsory education mathematics curriculum standards” made it clear that “should pay attention to port count, to strengthen estimates ”. Although many teachers know the importance of oral calculation, estimation, but some teachers passively
