学生的学习总是凭借自己已有的知识去认识和掌握新的知识。因此,教师在教学中要善于把具有内在逻辑联系的学习材料与学生原有的知识紧密联系起来,促使新知识进入学生原有的认知结构,从而形成新的知识系统。教学“九义”教材第二册中“求两数相差多少”一类应用题的关键是把“求两数相差多少”的问题转化为:求剩余”的问题,引导学生凭借已有的减法概念去分析“求两数相差多少”的数量关系,找到解答的方法,实现知识的迁移。
Students learn by virtue of their own existing knowledge to understand and master the new knowledge. Therefore, teachers in teaching should be good at the inherent logical connection between the learning materials and students' original knowledge closely linked to promote new knowledge into the original cognitive structure of students, so as to form a new knowledge system. Teaching “Nine Meaning” textbook in the second book, “what is the difference between the two numbers,” a class of application questions is the key to “ask the difference between the number of two” into the problem: seeking the remaining ", to guide students by virtue of the existing subtraction Concept to analyze the relationship between the number of the difference between the two numbers to find the answer to the method of knowledge transfer.
