很多初中生学习一些数学定理和概念后,无法对其有一个深刻的理解,所以在练习或考试时容易犯错误。但是,犯错误并不可怕,教师要从学生普遍所犯的错误中获得教学感悟,完善自己的教学方法,帮助学生有效地对错误进行纠正。根据多年的教学经验,笔者发现学生犯下这些错误的原因也是多方面的,当明确了他们所犯错误的原因后,才能更有针对性地开展教学,使得学生的思维得以良性发展。
Many junior high school students learn some mathematical theorems and concepts, can not have a profound understanding of it, so easy to make mistakes in practice or examination. However, making mistakes is not terrible. Teachers should obtain teaching sentiment from common mistakes made by students, improve their teaching methods, and help students to correct mistakes effectively. According to many years of teaching experience, I found that students make these mistakes for many reasons, when they have made clear the reasons for the mistakes, to carry out more targeted teaching, making the students a healthy development of thinking.
