在毕业班的总复习过程中,改错题教学是难度最大的。可以说,改正毕业班部分学生错误解题思路的过程,是小学阶段数学教学最难啃的一块“硬骨头”。怎样能在短时间内有效地啃下这块“硬骨头”呢?笔者的经验是:转变复习状态,把“静态”的批改变为“动态”的相互校对讨论,把每个人不同的错例变成全班共同的复习资源,在注重“共性”与“个性”的同时关注学生的心理和情绪、习惯与理解。通过教师引领、学生自主发现、同学之间的互动交流,寻找错误根源,探 In the general review of the graduating process, the error correction teaching is the most difficult. It can be said that the process of correcting the mistaken ideas of some graduating students is one of the hardest parts in mathematics teaching in primary school. How to effectively bite this piece of “hard bones” in a short time? The author’s experience is: to change the state of review, to turn the review of “static” into “proofread” of “dynamic” Personal differences of the wrong example into a common review of the class resources, focusing on “common ” and “personality ” at the same time pay attention to the students’ psychological and emotional, habits and understanding. Leading by teachers, the students discover themselves, interacting with their peers, searching for the root causes of mistakes, exploring
