新课程标准指出: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主要方式。作为一种形象、直观和生动的学习方式,动手操作深得学生和教师的喜爱,教学中如果应用得当,能促进学生对知识的理解,激起学生的数学思考,有利于数学问题的解决。那么,怎样从学生已有的知识经验出发,提高操作的实效性呢?笔者浅谈几点自己的想法。一、操作要把握好动手的时机“我听见了,但可能忘掉了;我看见
The new curriculum standard states: Effective mathematics learning activities can not rely solely on imitation and memory, hands-on practice, independent exploration and cooperation and exchange are the main ways for students to learn mathematics. As an image, intuitive and vivid learning methods, hands-on operation won the love of students and teachers, if properly applied in teaching, can promote students ’understanding of knowledge, arouse students’ mathematical thinking, is conducive to the solution of mathematical problems. So, how to proceed from the existing knowledge of students to improve the effectiveness of the operation? I talk about some of my own ideas. First, the operation must grasp the timing of hands-on ”I heard, but may have forgotten; I see
