学生的学习过程是由未知到已知,从片面到完整,从肤浅到深刻的过程,因而经常会出现各种各样的错误,教师在课堂教学中应做设陷阱,有意让学生出错,此时教师要因势利导,不怕暴露错误,引导学生仔细分析产生错误的原因,防患于未然,然后找出解答问题的正确途径。失败是成功之母,学生在学习中出现错误并不完全 The student’s learning process is from unknown to known, from one-sided to complete, from superficial to profound. Therefore, various mistakes often occur. Teachers should set traps in class teaching and intentionally make students make mistakes. Teachers must take advantage of the situation and are not afraid of exposing errors. They should guide students to carefully analyze the causes of the mistakes and take preventive measures before finding out the right way to answer the questions. Failure is the mother of success. Students’ mistakes in learning are not complete.
