七年级学生在整式运算中运算错误的分析

The Analyzing and Teaching Rethinking of the Errors Appears in 7th Grade Students' Integral Expression Operation

七年级学生的整式运算能力是学生数学学习程度的主要体现.采取试卷测试及教师访谈的方法考察了七年级学生在整式运算中的运算能力,统计了运算中出现的错误类型,进行了成因分析.旨在使初中数学教师对七年级学生在运算方面的优势与不足有一个全面的认识.根据学生出现的错误类型,提出符合七年级学生整式运算的教学策略和减少出错的教学方法.

Operational ability of junior middle school students is a mainly reflection of their primary mathematics learning standard. This paper have examined the operational capability of the 7th grade students by sample survey and questionnaire survey methods, and statistically analysis and classify the errors appeared in 7th grade students integral expression operation, thus making the teach- ers have a comprehensive understanding of the advantages and disadvantages on students＇ operational aspects. Then we designed a teaching method for integral expression operation teaching of seventh grade to reduce the mistakes according to the students former errors.
