一、背景介绍越来越多的数学教师注意到了折纸活动的数学教育价值,折纸活动可以直观地反映图形之间的关系以及变化规律,学生可以不借助任何现代技术,仅仅通过操作、观察、分析自己手中的一张纸经过反复折叠、旋转,很容易直观地发现结论和规律,有效地调动学生的积极性,学习也是事半功倍.但是很多数学实验课,只是流于形式地“折”出来,简单的实际操作后学生没有真正地进行数学思考,错失了数学实验课“证”出来的教育价值.笔者最近参加一次数学教研活动中,某位教师上了数学活动实验手册八上"折纸与
I. Introduction Background More and more math teachers have noticed the mathematics education value of origami activities. Origami activities can directly reflect the relationship between the figures and the changing rules. Students can use the operation, observation and analysis without any modern technology A piece of paper in his hands after repeated folding, rotating, it is easy to intuitively find the conclusions and laws, and effectively mobilize the enthusiasm of students, learning is also a multiplier .But a lot of mathematical experiment class, but in the form of After a simple operation, the students did not really think about mathematics and missed the educational value of mathematics experiment I recently participated in a mathematics teaching and research activities, Origami and
