“错误”在我们的教学中随处可见,是数学课堂不可避免的产物,我们许多数学教师也越来越重视课堂教学中学生的错例。通过对错例的探究,可以透视学生学习数学的过程,使教师获得教育教学的新启迪,同时学生在暴露错误的时候也经历了犯错—剖析—反思的过程,这对学生来说是非常重要的学习成长过程。一、有备辩错促思考(一)巧妙引导,有效纠错。在课堂教学中,当学生的回答有误或不符合要求时,教师要正视这 “Error ” is ubiquitous in our teaching. It is an unavoidable product of mathematics classroom. Many of our math teachers pay more and more attention to the mistakes of students in classroom teaching. Through the study of the wrong cases, we can see the process of students learning mathematics, teachers get the new inspiration of education and teaching, while students exposed the mistakes when it went through mistakes - analysis - reflection process, which is very important for students Learning and growth process. First, there are prepared to debate the wrong to promote thinking (A) Clever guide, effective error correction. In class teaching, when the student’s answer is incorrect or does not meet the requirements, teachers should face it
