“数学活动经验”的内涵有多种解释,有人认为它就是一种知识,有人认为它是个人的感受和体验,有人认为它是一种认识,张奠宇教授认为数学活动经验是专指“对具体的、形象的事物进行具体操作和研究所获得的经验”。所以,数学活动经验是一个丰富也很复杂的概念,它是看不见、摸不着的,具有实践性、个体性和内隐性。因此,我们应该抓住它的特点,帮助学生积累和发展他们的数学基本活动经验。一、教师心中要有目标 Some people think that it is a kind of knowledge, some people think that it is a personal feeling and experience. Some people think that it is a kind of understanding. Professor Zhang Tianyu thinks that the experience of mathematical activity refers specifically to “The experience gained from the concrete operation and research of concrete and image things”. Therefore, the experience of mathematical activity is a rich and complex concept, it is invisible, touching, practical, individual and implicit. Therefore, we should grasp its characteristics and help students to accumulate and develop their basic math experience. First, teachers should have a goal in mind
