본 연구에서는 초등학교 4학년 수학학습 부진학생을 대상으로 도형영역에 대해 수학저널 쓰기를 활용한 보충학습을 실시하여 수학 부진학생의 기하학적 사고 수준에 어떤 변화가 있는지 알아보았다. 연구 대상의 사전 기하학적 사고 수준 검사 결과에 기초하여 지도 내용을 van Hiele의 5단계 학습과정에 따라 재구성하여 주 1회 이상 12주간의 보충수업 후, 사후 기하학적 사고 수준 검사 결과 및 학생들이 작성한 수학저널과 수업 중 나타난 반응 및 면담 내용을 분석함으로써 부진학생들 외 기하학적 사고 수준 변화에 주목하였다. 더불어 의사표현력이나 협동활동과 같이 수학학습 부진학생의 교수-학습과 관련한 교수학적 함의를 얻을 수 있었다.

The aim of this study was to explore the grade 1-3 students' geometrical thinking level descriptors based on van Hiele level descriptors. The data were collected through collection of geometric curriculum materials such as indicators and learning standards in Basic Education Core Curriculum and mathematics textbook for grades 1-3. The findings were found that 1) Inconsistency between descriptors appeared on mathematics curriculum and Thai mathematics textbooks. 2) Using topics on textbooks as criterion for exploring 5 of 7 descriptors appeared on Thai mathematics textbook indicated geometrical thinking levels based on van Hiele's model merely level 0 (Visualization) across textbooks for grades 1-3.

학생들은 학교수학에서 중요한 위상을 차지하는 도형과 관련하여 다양한 사고를 하게 되며 학생들의 사고 수준의 파악은 교수-학습 효과로 직결되기 때문에 도형 지도와 관련하여 van Hiele의 기하 사고수준 이론은 중요하게 다루어진다. 기하 사고 수준의 도약적 특성 때문에 서로의 의사소통 불가능성까지 감안해야 한다는 시사점을 고려하면 지도하고자 하는 학생의 기하 사고 수준을 파악하는 것은 필수적이며, 뿐만 아니라 그들의 사고 수준 향상을 위해서 어떠한 지도 내용 및 방법을 구현해야 하는가도 핵심적인 기하 영역의 교육문제이다. 본 연구에서는 경남 통영의 한 초등학교 4학년 학생 10명을 대상으로 그들의 기하 사고 수준을 고려한 도형 단원의 교수-학습 지도안을 작성하여 적용함으로써 사고 수준의 변화를 관찰하고 수업을 분석한 결과, 학생들의 사고 특성 및 교수학적 시사점을 도출할 수 있었다.

This study investigated the types of the 3D geometric thinking and spatial reasoning through the observation of the 2D representing activities for representing the 3D geometrical objects with preservice secondary mathematics teachers. For this purpose, the 43 sophomoric students in college of education were divided into 10 groups and observed their group task performance on the basis of the representation they used. Observed processes were all recorded and the participants were interviewed based on the task. As a result, the role of physical object that becoming the object of geometric thinking and spatial reasoning, and diverse strategies and phenomena of the process that representing the 3D geometric figures in 2D were discovered. Furthermore, these processes of representing were assumed to be influenced by experience and study practice of students, and various forms of representing process were also discovered in the process of small group activities.

In this paper we give a description of students' obstacles in their learning of geometry, especially resulted from their confusing a physical drawing with a figure, a geometrical object which a physical drawing represents. In computer-based teaching-learning environment, we could relieve such obstacles through providing students for experiences in which they must focus on elements of a figure and relations of them. But there may be potential in computer-based environment if we offer students only visual experience for validity of geometrical gacts: students' lack of understanding for need of proof and experience of cognitive obstacles which is very important for students to reflect their thinking and activities. Thus an didactical treatment must follows, which we also give an example.

The analysis revealed that the pattern represent the function of written language, the Miao's idea of nature as tie object of worship and exorcism, and their primitive thinking. The patterns are chiefly embroidered collars, shoulders of blouse, waist blind and hem lines of skirt. The design of patterns are animals and plants and geometrical figured. Most of patterns are dragon, fishes, birds, butterflies, which are liked by the Miao people. The patterns are highly imaginative and true to life, and are made with strong national and popular features.

This paper presents the Global van Hiele (GVH) questionnaire as a tool for mapping knowledge and understanding of plane and solid geometry. The questionnaire facilitates identification of the respondents' mastery of the first three levels of thinking according to van Hiele theory with regard to key geometrical topics. Teacher-educators can apply this questionnaire for checking preliminary knowledge of mathematics teaching candidates or pre-service teachers. Moreover, it can be used when planning a course or granting exemption from studying in basic geometry courses. The questionnaire can also serve high school mathematics teachers who are interested in exposing their students to multiple-choice questions in geometry.

7차 교육과정의 초등학교 수학교과서를 살펴보면 자와 컴퍼스를 사용하여 삼각형과 원을 그리며, 삼각자를 활용해 수직선과 평행선을 그리는 작도 교육이 이루어지고 있다. 본 연구는 2010년 초등학교 6학년 학생들의 작도 과정에서 나타나는 수학적 사고를 분석하여 초등학교 작도지도의 시사점을 제안하고자 한다. 연구결과 영재학급 6학년 학생들은 교사의 적절한 조언이 뒷받침되면 선분의 등분할 작도를 통해 유추, 연역, 발전, 일반화, 기호화의 사고와 같은 수학적 사고가 가능하며, 일반학급 학생들에게도 현행 교육과정보다 심화된, 자와 컴퍼스를 이용한 수직이등분선, 사각형, 마름모, 선분의 연장 등의 작도는 교육이 가능하다.

The purpose of this study is to understand what two models of SOLO taxonomy and van Hiele theory suggest and find out what relation there is between the category system of the SOLO taxonomy and the thinking level of the van Hiele theory. The van Hiele theory describes in line of ranking level so that it may increase the teaching effects by putting together a class, which takes into consideration the students thoughts. The SOLO taxonomy focused on the response mode of the students rather than the thinking level or the developmental stage of them to pursuit the method that can describe the students understanding in depth quality-wise. Although the SOLO taxonomy and the van Hiele model seem to have different form and character from outside in terms of their goals, a closer examination reveals that the two stances have much in common and that the models are complementary. Although the van Hiele placed more focus on the thoughts, because the conclusion was based on the students responses, the van Hiele theory can be interpreted within the structure identified in the SOLO model. In this study, we have tried to understand how the response structure form the SOLO taxonomy and the thinking level of the van Hiele theory are related, based on the studies of Pegg and Davery1998). If you briefly look at them, there are following corresponding relation between the SOLO taxonomy and the van Hiele theory. a) The relational level(R) in iconic moe is van Hiele level 1. b) The multisturctural level(M$_2$) in the second cycle of concrete-symbolic mode is van Hiel level 2. c) The relation level(R$_2$) in the second cycle of concrete-symbolic mode is van Hiele level 3. d) The unistructural level(U$_2$) in the second cycle of formal mode is van Hiele level 4. e) The postformal mode is van Hiele levle 5. Though it would be difficult to conclude that these correspondences were perfectly done, if you look at their relation, you can see that the learning process of the students were not carried out uniformly. Therefore, by studying the students response structure, using the SOLO taxonomy, and identifying the learning cycle and understand the geometrical concept more in depth.
