摘要
空间几何数学实验对于培养学生的数学实践能力、完善空间几何教学体系,开发培养学生直观几何思维潜力与创新能力起着十分重要的作用,但空间几何实验如何有效结合几何学科知识、符合学生几何直观能力发展规律,空间几何学具应该如何选择与设计都是亟待解决的问题.该文在对“几何直观能力”“数学实验”等关键概念进行梳理后,综合国内外关于几何直观能力发展规律和数学实验理论基础,总结了数学实验设计的总路径,提出了基于小学生几何直观能力发展规律的前端分析三维模型(T-K-T模型),以此模型为基础应用实例进行前端分析设计与活动分析,以期为相关研究工作提供参考与借鉴.
Space geometry mathematics experiments play a very important role in developing the students'ability of mathematical practice,perfecting the space geometry teaching system and cultivating the students'geometric thinking potential and innovation ability.However,how to effectively combine geometric experiment space geometry knowledge and conform to the development law of students'geometric intuitive ability and how to choose and design space geometry learning tools are problems urgent to be solved.After combing the key concepts such as"geometric intuitive ability"and"mathematical experiment",this paper has synthesized the development rules of geometric intuitive ability and the theoretical basis of mathematical experiment at home and abroad,summarized the general path of mathematical experiment design,and proposed a 3D model(T—K—T model)the geometry based on the law of elementary school students'development of geometric intuition ability.The front-end analysis design and activity analysis have been undertaken in order to provide reference for the related research work.
