知识的迁移是指运用已有的知识来学习新知识、解决新问题,从而获得触类旁通、举一反三的学习效能。学习迁移有两种,一种是正迁移;一种是负迁移。在小学数学教学中,学生由于受年龄和心理特点的影响,以及数学抽象概念的制约,往往会出现“负迁移”的现象,从而导致学生概念混淆,思维僵化,误走弯路,甚至造成错误,这对提高教学质量十分不利。因此,在小学数学教学中,我们要认真贯彻《数 The transfer of knowledge refers to the use of existing knowledge to learn new knowledge and solve new problems, in order to gain the ability to learn by analogy and learn from the truth. There are two kinds of learning migration, one is positive migration; one is negative migration. In elementary mathematics teaching, because of the influence of age and psychology, as well as the restriction of mathematical abstraction, students tend to have “negative transfer” phenomenon, which leads to the confusion of students, rigidity of thinking, mistakes and even causes Mistakes, which is very unfavorable to improving the quality of teaching. Therefore, in primary school mathematics teaching, we must conscientiously implement the "number
