学生在学习的过程中常常会出现一些错误,出错并不可怕,可怕的是学生对于一些做过多次的练习题,会一错再错,这就是教师需要关注的重点。在数学教学过程中,教师要注重分析学生,对学生们常会出错的一些练习做到心中有数。在课堂教学中,可以适时的渗透一些学生的错例,和学生共同分析原因,并采取一定的纠正措施,帮助学生再度提高,实现错例的价值。 Students in the learning process often appear some mistakes, mistakes are not terrible, terrible is that students do a number of exercises for some, will be a mistake, this is what teachers need to focus on. In the teaching of mathematics, teachers should pay attention to analyzing students, and know a few exercises that students often make mistakes. In classroom teaching, we can timely infiltrate some of the wrong examples of students, and students analyze the reasons together, and take some corrective measures to help students improve again to achieve the value of the wrong example.
