《新课程标准》明确指出:学生能够正确地进行整数、小数、分数的四则运算,对基本的运算要达到一定的熟练程度。然而,在教学过程中,我发现不少学生的计算错误率较高,学生计算的错误率一直成为影响学生学业成绩的主要因素,也是数学教师最头痛的一件事。我认为学生计算错误率高是有多方面原因的:一、学生的不同个性引起计算出错一般来讲,有些学生积极主动、喜欢表现、思维敏捷,但是做事粗心、性子急、常把现象当本质,从而导致运算的准确性较 The New Curriculum Standard clearly states that students can correctly carry out four arithmetic operations on integers, decimals and fractions and achieve certain proficiency in basic operations. However, during the teaching process, I found that many students have a high computational error rate. The error rate calculated by students has always been a major factor that affects students' academic performance. It is also one of the most headaches for math teachers. I think students calculate the high error rate for many reasons: First, the students of different personality caused by calculation error Generally speaking, some students are proactive, like performance, quick thinking, but work careless, temper, often the phenomenon as the essence , Resulting in more accurate operation
