正确运用迁移规律,尽量扩大正迁移的有利影响,防止和减少负迁移的干扰作用,是数学教学中一个值得研究的课题。一、正迁移规律的利用在数学教学中,怎样才能充分发挥正迁移的作用呢?第一、提高对已有知识的概括水平,为正迁移打好基础。如果概括不确切,迁移过程就会发生这样那样的障碍。例1.对于“三角形的高”的概念,学生可能不自觉地作出以下几种错误的概括:(1)认为“三角形的高就是从上面的角顶到 Proper use of the law of migration, try to expand the positive impact of migration, to prevent and reduce the interference of negative migration is a subject worthy of study in mathematics teaching. First, the use of the law of migration In mathematics teaching, how can we give full play to the positive role of migration? First, to raise the level of generalization of existing knowledge, lay a good foundation for positive migration. If summarized inaccurately, such an obstacle can occur during the migration process. Example 1. For the concept of “high triangles,” students may unconsciously make the following mistakes: (1) Think "the height of the triangle is from the top of the corner to
