有些学生学习数学 ,尤其到了高年级 ,虽然耗时不少 ,精力投入较多 ,学习刻苦认真 ,但收效甚微 ,原因何在 ?有人认为是学习方法不当 ,而笔者觉得更主要的原因是思维方式不对 ,习惯于循规蹈矩 ,已有的认识没能得到充分的反思 ,确切地说就是缺乏反省 (ｒｅｆｌｅｃｔ)思维意识所致 Some students study mathematics, especially in the upper grades. Although they take a lot of time, devote more energy, and study hard, but have little success, why not? Some people think that learning methods are not proper, and the author thinks that the more important reason is the way of thinking. No, they are accustomed to behaving themselves. The existing knowledge has not been fully reconsidered. It is precisely due to the lack of reflection consciousness.
