小学数学课程标准指出:有效的数学学习活动不能单纯地依赖模仿与记忆,动手实践、自主探索与合作交流是学生学习数学的重要方式。学生应当有足够的时间和空间经历观察、实验、猜测、计算、推理、验证等活动过程。在这种新视野下,我们不仅要在平时的课堂教学中引入数学实验,更应结合教材,选择和开发习题中或“做中学”内容里的实验资源,让他们在研究的过程中探索数学新知识,体验研 Primary mathematics curriculum standards that: effective mathematics learning activities can not simply rely on imitation and memory, hands-on practice, independent exploration and cooperation and exchange is an important way for students to learn mathematics. Students should have enough time and space to go through the process of observation, experiment, speculation, calculation, reasoning, verification and other activities. In this new perspective, we not only need to introduce mathematical experiments into everyday classroom teaching, but we should also select and develop experimental resources in the exercises or in the content of “learning by doing” in combination with the teaching materials so that they can be used in the research process Explore new math knowledge, experience research
