美国教育家杜威说:“一盎司经验胜过一吨理论。”数学的理论学习是为实践提供一个基础,理论的学习是不可或缺的。但是,仅有理论知识并不能让学生在学习数学方面有所突破,只有结合实践方面的知识,才能让学生将所学习的知识进行总结与反思,并进一步拓展提升。因此,在小学数学教学中要多注重开展操作活动,在活动中实践并积累经验。 Dewey, an American educator, said: “An ounce of experience is worth a ton of theory.” Theoretical study of mathematics provides a basis for practice, and theoretical learning is indispensable. However, only the theoretical knowledge does not allow students to make a breakthrough in the study of mathematics. Only by combining the practical knowledge, can students summarize and reflect on the knowledge they have learned and further expand and improve. Therefore, in primary school mathematics teaching should pay more attention to carry out operational activities in the activities of practice and gain experience.
