在平时的数学教学中,我们发现,对一些典型错误,反复强调,又多次进行过强化训练,可在作业、考试中,学生仍然犯同样的错误.其实学生一再出错,关键在于他们只知其然,不知其所以然,在学习中缺少悟的过程,这需要教师挖掘学生在解题中发生错误的原因,对症下药,引导学生深入反思.本文通过几个例子,剖析致错原因,希望能通过对错题的解剖吃一堑长一智,进而将误化为悟,提高我们解题的“免疫力”.一、数学概念理解模糊,导致出错
In normal mathematics teaching, we find that repeated repetition and emphasis on some typical mistakes and repeated intensive training, students can still make the same mistakes in homework and examinations. In fact, when students make mistakes again and again, they only know Of course, I do not know why, in the process of learning lack of enlightenment, which requires teachers to explore the students in the problem-solving errors, the right medicine, to guide students in-depth reflection.Through several examples, the paper analyzes the causes of errors, hoping to pass Anatomy of the wrong title to eat a cutting-edge wisdom, which will be mistaken for enlightenment and improve our problem-solving “immunity ” First, mathematical concepts to understand fuzzy, leading to errors
