数学错例分析及对数学课堂教学的启示

Analysis of Error Cases and its Enlightenment to Mathematics Teaching

错例暴露学生的真实思维,是学习知识后的反馈,潜藏着丰富的教学资源,具有很大的研究价值。开展错例研究,可以引导教师充分挖掘错例蕴含的教学资源,促进教师养成研究学生和反思教学的习惯。教师通过对错例的研究,还能帮助学生理清做题思路,找出错误原因,消除畏难情绪。通过对中考错例的收集、整理和分析,论述错例分析对课堂教学的指导意义,旨在帮助教师提升专业水平,帮助学生提高学业成绩。

The error cases that expose the students’ real thinking are the feedback of students after their learning knowledge and hide abundant teaching resources. The error cases have great research values. The study of error cases can guide teachers to tap the teaching resources in the error cases and promote teachers to form the habit of researching students and reflective teaching.

The author collected, sorted and analyzed the error cases in senior high school entrance examination. This paper discusses the instruction meaning of the error cases analysis to the mathematics classroom teaching and it aims to help teachers improve their professional level and help students improve their school achievement.
