小学生小数乘法计算错误原因及解决策略研究

A Study on the Causes and Solutions for the Miscalculation of Elementary School Students'Decimal Multiplication

小数乘法是“数与代数”中不可或缺的重要内容,它与整数乘法既联系紧密又相互区别,是学生在生活及学习中应用较为广泛的数学知识。然而,在计算时学生却经常出现这样那样的错误,直接影响学生学习数学的兴趣,通过对小学生小数乘法计算错误原因进行探究,找出解决策略,将有助于降低计算错误率,有助于教师提高教学的质量。

Decimal multiplication is an indispensable and important content in"number and algebra".It is closely related to integer multiplication and is different from each other.It is a widely used mathematical knowledge that students use in life and study.However,students often make mistakes of this kind in calculation,which affect their interest in learning mathematics.By exploring the causes of errors in calculation of primary school students'decimal multiplication and finding out solutions,it will help to reduce the error rate of calculation and improve the quality of teaching.
