多数教师总是习惯在评价学生的练习、测验时埋怨学生出错,无形之中把这种反反复复的错误归咎于学生身上.殊不知是自己在日常的讲评中,忽略了对学生出现的错误进行正确有效的引导,致使学生未认清错误的实质,无从下手.这样反复做反复错的现象,也就不足为奇了.有效地指出学生的错误是数学教学的基本内容之一,是学生再次调整、强化认知结构的过程.教师如果能以学生学习过程中出现的错误为教学资源,帮助学生从基本概念、基础知识的角度剖析错误产生的原因,帮助学生找出错误的来源,并发展该问题,找到更成熟的解法和一般结论,会收到事半功倍的效果.
Most teachers are always accustomed to assessing students’ practice, complaining students to make mistakes during the test, and invisibly blaming students for their repetitive mistakes, not knowing that they neglected their mistakes in their everyday comments Proper and effective guidance, resulting in the students did not recognize the essence of the error can not start. Repeatedly doing repeated wrong phenomenon, it is not surprising that effectively point out that the mistakes of students is one of the basic content of mathematics teaching, students once again Adjust and strengthen the process of cognitive structure.If the teacher can make mistakes in the process of student learning as teaching resources to help students from the basic concepts and basic knowledge of the reasons for the error analysis to help students identify the source of the error and development The problem, finding a more mature solution and a general conclusion, will yield a multiplier effect.
