在数学教学过程中,经常会发现学生在解题中犯下各种各样的错误,事后师生都在努力纠错.教师讲得真累,学生纠得好苦,可是效果却不明显,到下次解题时又重复“昨天的故事”.为什么呢?虽然原因很多,但很关键的是学生没有深层次地找到错误的真正原因,没有一个与错误作“斗争”的过程,未能产生认识冲突,对错误印象不深刻,没有反思总结,没有揭示问题的本质,当然就一错再错了. In mathematics teaching process, often find that students make a variety of mistakes in the problem-solving, after-school teachers and students are trying hard to correct the teachers really tired, the students correct the bitter, but the effect is not obvious, To the next problem-solving again “Yesterday’s story ” Why? Although there are many reasons, but the key is that students do not find the real cause of the error, there is no one with the wrong “struggle” Process, failed to generate awareness of conflict, impressed the wrong impression, did not reflect on the summary, did not reveal the nature of the problem, of course, a mistake and wrong.
