由于当前数学新课程对“过程与方法”的关注,“数学基本活动经验”逐渐成为数学教学的一个热门话题。数学活动经验的积累,大致需要经过“经历、内化、拓展”的过程。首先,需要经历,经历活动的过程,经历思维的碰撞,但仅仅有经历是远远不够的,在经历的基础上还要不断反思活动过程,使活动所得不断内化、拓展,最终延伸到其他的学习活动和生活中去。 Due to the current mathematics curriculum focus on “process and method ”, “basic experience of mathematics ” has gradually become a hot topic in mathematics teaching. The accumulation of experience in math activities generally needs to go through the process of “experiencing, internalizing and expanding”. First of all, we need to experience and experience the process of activities, experience the collision of thinking, but only experienced is not enough, based on experience but also continue to reflect the process of activity, the activities continue to internalize, expand, eventually extending to other Learning activities and life to go.
