活动是认识的基础,智慧从动作开始。儿童动手操作,一方面是手与眼协同活动对客观事物的动态感知,另一方面又是手与脑密切配合,把外部系列活动转化为内部言语形态的智力内化方式。他们在视觉、触觉、运动协同感知事物的同时,正以活跃的内部言语体验情境,展开思维。他们在操作时必须也必然地同时思考:如何摆放、如何分析、如何剪拼、如何折叠……而操作中获得的形象和表象,又及时推动他们或进行分析、综合、比较、抽象、概括,或进行归纳、类比、猜想,进而深刻理解抽象的数学知识,有效地激发兴趣,使学生 Activity is the basis of understanding, wisdom from the beginning of the action. Children’s hands-on operation, on the one hand, is the dynamic perception of objective things by the coordinated activities of hand and eye, on the other hand, the internalization of intelligence by closely coordinating the hand and the brain and transforming the external series of activities into the internal forms of speech. They visualize, touch, and sense of movement in collaboration with the same time, are active in the internal language to experience the situation, start thinking. They must also think about the operation at the same time: how to display, how to analyze, how to cut a clip, how to fold the image and appearance obtained from the operation, and promptly promote them or analyze, synthesize, compare, abstract, summarize , Or induction, analogy, guess, and then a deep understanding of abstract mathematical knowledge, effectively stimulate interest so that students
