토마스 쿤의 패러다임 이론은 수학의 혁명적 과정을 설명하는 데는 충분치 않으며, 학제간 연구에는 더욱 그러하다. 본 논문에서는 현대건축에 나타난 위상기하적인 요소를 고찰하고, 우리나라 전통건축과 서양의 현대건축과의 강한 유사성을 비교할 때 시대정신으로는 설명이 불충분하여 범 패러다임이란 개념으로 설명한다.

Mathematics is means for making sense of one's experiential world and products of human activities. A usefulness of mathematics is derived from this features of mathematics. Keeping the meaning of situations during the mathematizing of situations. However, theories about the development of mathematical concepts have turned mainly to an understanding of invariants. The purpose of this study is to show the possibility of computer in representing situation and phenomena. First, we consider situated cognition theory for looking for the relation between various representation and situation in problem. The mathematical concepts or model involves situations, invariants, representations. Thus, we should involve the meaning of situations and translations among various representations in the process of mathematization. Second, we show how the process of computational mathematization can serve as window on relating situations and representations, among various representations. When using computer software such as ALGEBRA ANIMATION in mathematics classrooms, we identified two benifits First, computer software can reduce the cognitive burden for understanding the translation among various mathematical representations. Further, computer softwares is able to connect mathematical representations and concepts to directly situations or phenomena. We propose the case study for the effect of computer software on practical mathematics classrooms.

Mathematics has been usually recognized as value-neutral and anti-ideological subject, and as a result, it has not dealt with environmental problems clearly. Also, it is not easy to find any environment-related contents in the 7th mathematics curriculum. However, because mathematics is also precious human products and essence, in any ways there is a need to reflect the social issues in the mathematics subject which speak for human mental activities. If this need is admitted to change the mathematics contents to the direction of social issues, environmental problems can stand out and be dealt in the mathematics education. Among the 6 domains in the 7th mathematics curriculum, the environmental problems can be dealt with in the domains of ‘numbers and operation’, ‘letters and formulas’, ‘regularity and function’, ‘chances and statistics’, ‘measurement’ except in the domain of ‘diagrams’. Also, the '문장제들' which takes up a considerable part of mathematics textbooks needs the authentic situation, and thus it will be possible to take environmental situations as mathematical materials. Furthermore, one of the 7th mathematics curriculum is that it suggested further study in each level of each domain, the representative pattern of which is the application of the mathemantics contents to the daily life. With this kind of mathematics further study contents, environmental problems can provide a variety of contents for the further study. From this viewpoint, it can be expected that the contents of environmental education will be increased in the mathematics subject. Under the recognition that the mathematics subject cannot be an exception in considering environmental problems, this study has studied some concrete plans and examples for how the mathematics textbooks based on the 7th educational curriculum can deal with environmental Problems.

In this paper, we designed an open class teaching model in level-based team arrangements. In this way, teaching lesson plans were newly developed in order to teach students in open classroom environments. Both teachers and students required enough time to be acquainted with the new approach. However, empirical data analyses of mid-term and final examinations as well as survey data mathematical achievements indicated that most of the students have shown interests in mathematical activities and confidences on their mathematical abilities. Furthermore, there were few students who seemed to be isolated from mathematical activities. In particular, most students didn't seem to get lower grades than expected from other teachers who hesitated to apply the new model.

The purpose of this article is to study characteristics of Soma Cube in combinatorial-geometric point of view, and to present basic substances and direction for efficient Soma cube activities in school mathematics upon systematical analysis of methods of finding solutions using Inclusion-Exclusion Method. We can apply Inclusion-Exclusion Method to find all possible solutions in Soma Cube activities not as trial-and-error method but as analytical method. Because Inclusion-Exclusion Method can reduce the number of problem-solving variables by making high conjunction in the choice of pieces. Soma cube pieces can be sorted as 'flat' ones and 'non-flat' ones, which would be another effective method in the manipulation of Soma Cube pieces.

요즘 지식과 앎(knowing)에 대한 새로운 인식론적 패러다임으로 떠오르고 있는 구성주의(constructivism)에 접하여 여러 가지 학습 방법들이 제시되고 있으나 체계적이고 획기적인 대안이 나오는 것은 아니다. 구성주의를 주창하는 사람들이 제안하는 교수 학습 방법은 이미 관심 있는 교사들이 실천하고 있는 학습 방법이다. 이런 맥락에서 교실 현장에 밀접한 연구 결과와 많은 학습 방법을 제시한 Richard Skemp의 이론을 구성주의에 비추어 해석하고 그의 수 개념 기초를 위한 여러 놀이 활동을 소개하고자 한다.

In this study, we will develop and implement the teaching program of 'Function', on the subject of "Poster-Making utilizing the Graph Art" in the Math Camp for middle-school students. And we will examine the didactical significance through student's activities and products. The teaching program of 'Function' utilizing the Graph Art can be promoted self-directly the understanding of 'Function' concept and the ability for handling 'Function'. In the process of drawing up the graph art, in particular, this program help students to promote the ability for problem-solving and mathematical thinking, and to communicate mathematically and attain the his own level. Ultimately, this program have a positive influence upon cognitive and affective and areas with regard to mathematics.

모델링 활동은 학생들의 메타인지적 사고를 촉진할 수 있는 환경을 제공할 것이라는 시각에 기반을 두어 본 연구를 행하였다. 따라서 사례연구 방법으로 중학생들의 모델링 활동에서 어떤 메타인지적 사고가 나타나는지를 조사하였다 연구 결과, 학생들이 모델링 활동을 하는 동안 모델을 개발하기 위해 자신의 활동을 모니터하고 제어하는 메타인지가 자발적으로 활성화되었다. 또한 소그룹으로 모델링 활동을 하면서 자기평가와 동료평가가 활성화되었고, 이를 통해 모델을 수정하고 정교화하면서 일반화 가능한 모델을 개발하였다.

While the utility of the number line is considerable, articulating its conceptual foundation is often neglected in school mathematics. We suggest that it is important to build up strong conceptual foundations in the earlier grades so that number lines can be used in a more meaningful way and that any misconceptions associated with the number line can be prevented or intervened. This paper addresses unit, direction, and origin as the key elements of number lines and presents activities from Davydov's curriculum for early grades that promote exploration of those key elements and may resolve some students' misconceptions. As shown in sample activities from Davydov's curriculum, this paper suggests that students can broaden their perspectives on the number line and use it versatilely in various areas of mathematics learning when they deeply engage in the construction of a number line and have flexibility in interpreting the relationships between key number line elements.

각기 다른 상황에서 각기 다른 활동을 통하여 이루어진 학습의 연속성과 그 변환 과정을 살펴보고, 이 때 일어나는 학습자의 목표와 활동 사이의 관계, 그리고 타인과의 상호작용의 영향을 분석하는 것이 본 연구의 목적이다. 이를 위하여, 5명의 학생들을 각기 다른 상황에서 확률과 관련된 다양한 활동들을 해 보게 하였으며, 집단 면담과 개별 면담, 관찰 등을 통하여 그들의 학습과정 및 사고를 분석하였다. 그 결과, 다양한 상황과 활동 속에서 타인과의 상호작용을 통하여 초기 학습 목표를 수정하여 새로운 목표를 설정하고 다른 활동에서 다시 이를 조정, 발전시키는 반복 과정을 통해 학습의 연속성과 변환이 발생하였으며, 특히, 타인과의 상호작용이 새로운 목표 설정과 전략을 수립하는 데에 결정적 역할을 함을 알 수 있었다. 이는 학습자의 인지 발달 및 수학 학습에 있어 적절한 과제 제시와 교사 역할의 중요성뿐만 아니라 학교와 학교 외 활동간의 높은 연속성이 학습을 촉진하고 의미 있게 할 수 있다는 가능성을 제시한다.
