数学学习总是以一定经验和知识为前提,在联想的基础上更好地理解和掌握新知,这里的联想指知识的联结过程,教学中总是会出现学生对新知识理解不够,不能运用知识解决实际问题的现象,很重要的一个因素是老师没有组织学生进行有意义的学习,没有找到新旧知识之间的内在联结,没有帮助学生建立有效的、稳固的认知结构,这里讲到的认知结构,就是学生通过自己积极主动的认识在头脑里建立起来的数学知识结构。数学学习过程本身就是一种认识活动,数学教学的 Mathematics learning is always based on the experience and knowledge as a prerequisite to better understand and grasp the new knowledge on the basis of the association, where the association refers to the process of knowledge, teaching, there will always be students understand the new knowledge is not enough, can not use knowledge One of the most important factors in solving the problem of actual problems is that the teacher did not organize the students to make meaningful learning, did not find the intrinsic link between old and new knowledge, did not help students to establish an effective and stable cognitive structure, Known structure, is that students through their own initiative to understand the mathematical knowledge structure built in mind. Mathematics learning process itself is a cognitive activity, mathematics teaching
