初中立体几何对于学生空间抽象思维能力的培养具有举足轻重的作用。我们在分析了传统立体几何教学和当前相关支撑软件优缺点的基础上,依据建构主义学习理论、整合点分析方法及新课标和大纲要求,同时还兼顾了初中学生认知特点以及当前几何学习中的主要困难点,提出了可以有效支撑立体几何学习过程中模型投影、展开折叠、模型切割三大重难点知识内容的支撑环境,并对支撑环境的总体框架及功能模块进行了阐述,最后给出一些案例来演示如何将软件应用于初中立体几何教学当中。
The three-dimensional geometry of junior middle school plays an important role in the cultivation of abstract thinking ability of students. Based on the analysis of the advantages and disadvantages of the traditional three-dimensional geometry teaching and the current supporting software, based on the constructivism learning theory, the integration point analysis method and the requirements of the new curriculum and syllabus, we also consider the cognitive characteristics of junior high school students and the current geometry learning The paper puts forward the supporting environment which can effectively support the knowledge content of the three major difficulties in projection, expansion and model cutting during the course of three-dimensional geometric learning, and expounds the overall framework and function modules of the supporting environment. Finally, Some cases to demonstrate how to apply the software to junior high school geometry teaching.
