摘要
本研究旨在根据范·海尔关于四边形主题的思维水平来描述初中生的几何思维水平和几何思维过程。定性方法是本研究使用的研究方法,通过案例研究法,测试改编自Usiskin的CDASSG的Van Hiele Geometry Test (VHGT)和改编自Burger and Shaughnessy(1986)的访谈指南,以识别、定义和分类的形式对思维过程进行访谈。本研究的对象是297名七年级和八年级的学生,他们来自位于伦邦街道的两所学校。VHGT测试结果显示,有81名学生计数为0级(可视化)。结果表明,第7级和第8级的学生表现为:1)学生能够识别四边形的类型,但仍然受到原型的影响;2)学生不能对四边形进行分类;3)总体上按照范海勒的思维特征,以识别、定义和分类方面的形式描述了第0级的几何思维过程。

This research aims to describe the level of geometric thinking and geometric thinking processes of Junior High School students according to van Hiele's level of thinking on the topic of quadrilaterals. The qualitative approach is the research method used in this study through a case study method by testing the Van Hiele Geometry Test (VHGT) which was adapted from Usiskin's CDASSG and conducting interviews about the thinking process in the form of identifying, defining, and classifying which was adapted from the interview guide of Burger and Shaughnessy (1986). The subjects of this study were 297 grade VII and VIII students from two schools located in the Lembang sub-district. The results of the VHGT test showed that there were 81 students counting level 0 (visualization). The results showed that the students of class VII and VIII level 0 were as follows: 1) students were able to recognize the types of quadrangle but still affected by the prototype, 2) students were not able to classify quadrilaterals, and 3) overall description of the geometric thinking process level 0 in the form of identifying, defining, and classifying aspects according to van Hiele's thinking characteristics in general.
