                                  一、易错题教学的意义

                                  二、初中数学易错题成因剖析

                                  (一)忽视概念理解

                                星云棋牌官网下载   SHUXUEGAINIANDEXUEXISHIJIETIDEJICHUYESHIJIETIDEYIJU,YIXIEXUESHENGDUIGAINIANDEZHANGWOMOHUBUQING、LIJIEBUDAOWEI,JIETISHIDUIGAINIANDESHIYONGSHENGBANYINGTAO,SHIYONGCUOWUGAINIANJIEXITIMU,FANGFAYUTIMUBUPIPEI。YINWEIZAICHUZHONGSHUXUEXUEXIZHONG,HENDUOZHISHIDIANDEGAINIANZHIJIANSHICUNZAINEIZAIGUANLIANDE,DANSHI,RUGUOXUESHENGWUFALIQINGCHUZHISHIDIAN、GAINIANZHIJIANDECHAYIHEBUTONG,HENRONGYIFASHENGJIYICUOWUHUOZHEHUNLUAN,ZAIJIETIHUOZHELIJIETIMUDESHIHOU,HENRONGYITOUHUANGAINIAN,DAOZHIJIETICUOWUHUOZHEWUFASHUNLIJIETI。

                                  (二)审题不清,滥用条件

                                  因为审题不仔细,看漏、看错题中所给条件,导致错误解答。对于综合性问题的解决,考虑不全面,局限于题目中列出的条件,缺乏深度思考能力和信息挖掘能力,忽视所给条件的适用范围。在解二次方程、二次函数相关题目时,常常会忽略题目中所包含的隐藏条件,例如二次项系数不可为零、根的判别式大于等于零等等。初中阶段的学生本身心理不够成熟,他们不够沉着冷静,尤其是大部分学生会表现出比较马虎,不够认真、仔细等心理特征,在读题或者审题的时候,还没有理解清楚题目,就直接动手开始解题,最终导致问题理解不清楚,解答的过程出现错误,整个计算结果不正确。

                                  (三)忽视解题的全面性

                                  (一)教学过程经验的总结
