瑞士教育学家皮亚杰说过“知识来源于动作。”这充分说明了动手操作的重要性,新课程要求学生学习知识要重视知识发展的过程,实践是学生发展的原动力,教师只有在教学过程中巧妙地引导学生动手、动脑,学生的发展才能在真正意义上得到落实。而动手操作是小学数学课堂教学中最直接、最常用的实践活动。近几年来,我在长期的数学教学中体会最深的一点是:多让学生动手操作,创造一个愉快的学习氛围,是提高教学质量的一个重 Piaget said that "This fully demonstrates the importance of hands-on operation, the new curriculum requires students to learn knowledge should pay attention to the process of knowledge development, practice is the driving force behind the development of students, teachers only In the teaching process skillfully guide students hands, brains, the development of students can be implemented in the true sense. The hands-on operation of primary school mathematics classroom teaching is the most direct and most commonly used practice. In recent years, my deepest understanding in long-term mathematics teaching is that letting students practice more and create a pleasant learning atmosphere is a heavy task to improve teaching quality
