정보화시대를 맞아 어느 때보다도 활발히 전교과에 걸쳐 학생의 의사소통의 능력을 향상하기 위한 다양한 방법이 모색되고 있다. 학교현장의 수학교육자는 수학교수-학습에서 어떤 상호작용이 일어났는지, 특히 다루기 쉬운 도구로써 계산기가 주어졌을 때 어떻게 학생의 지식 발달이 언어적 상호작용에서 이루어지는지를 알아야 한다. 본 연구는 이러한 학생의 상호작용을 분석할 때 필요한 분석도구를 개발하는 것이다. 예비연구와 본 연구를 통해 언어적 상호작용의 구성요소가 세 영역, 즉, 지식구성 진술, 사회적 상호작용 진술, 그리고 교사의 교육어 진술에서 개발되었다. 본 연구에서 개발한 자료를 이용하여 특히 학생의 지식 구성 발달에 따른 상호작용의 구성요소의 특징을 파악하고 이에 필요한 언어적 상호작용의 역할과 활성화 방안을 모색하는 연구가 가능하다.

수학학습장애는 독해장애와 더불어 학습장애의 주요영역으로 인식되고 있다. 그러나 독해 장애에 대한 연구와 비교하였을 때 상대적으로 주목받지 못한 분야로, 과연 수학학습장애는 무엇이며, 수학학습장애 아를 판별하는 기준을 어떻게 설정할 것인가의 문제가 여전히 논란이 되고 있다. 본고에서는 수학학습장애에 대한 최근의 세 가지 관점-신경학적 관점, 발달심리적 관점, 교육적 관점-의 고찰을 통해, 수학학습장애를 진단하기 위한 하나의 통합적 관점이 필요함을 제안하고 있다. 이것은 수학학습장애를 신경적 결함으로만 해석하려는 전통적 관점에 대한 발달심리학자들의 비판을 수용한 것이며, 오늘날 파행적인 교육체계에서 희생되고 소외되어온 학생계층을 포용하기 위한 한 가지 제안이 될 것이다.

A case study was conducted to investigate the understandings of the subject matter knowledge and pedagogical content knowledge held by 63 elementary preservice teachers in dealing with the division by a fraction. The study results showed that, in terms of the subject matter knowledge, the preservice teachers did not have a conceptual understanding of the division by a fraction and, in terms of the pedagogical content knowledge, they depended heavily on algorithms without a conceptual understanding of the meaning of the division by a fraction.

The perspective on this study assumes that the mathematical modeling activity provides students with the environment which promotes metacognitive thinking. The purposes of this paper are to investigate metacognitive thinking on the mathematical modeling with the result of case study. The study revealed that development of students' model was accompanied with the control and monitoring of modeling activities. Also students refined the model by self-assessment and peer-assessment in small group modeling activities and developed generalizable model.

The matter of understanding mathematical concepts in learning mathematics is one of the most important issues in mathematics education. There have been so many studies about it but the more practical study has been asked. When we Think using intuitional models such as examples, figures of speech, situations and activities, it is supposed that the major elements of cognitive mechanism are prototypes, analogies, metaphors and metonymies. In this paper, we tried to examine Rosch's prototype theory, the studies about analogies in congnitive psychology, Lakoff and Johnson's metaphor theory from the viewpoint of teaching mathematics, and then tried to analyze examples, analogies, analogical transfers, metaphorical expressions, metonymies in middle school mathematics text books used in Korea now.

The purpose of this paper is as follows: $^{\circleda}$ to disclose the essence of symmetry $^{\circledb}$ to propose the desirable strategy of problem-solving as to symmetry $^{\circledc}$ to clarify the relationship between symmetry and group $^{\circledd}$ to propose a way of introduction of 'group' in school mathematics according to its fundamental characteristic, symmetry. This study shows that the nature of symmetry is 'invariance under a transformation' and symmetry is the main idea of 'group'. In mathematics textbooks and mathematics education literature, we find out that the logic of symmetry is widespread. We illustrate two paradigmatic problem related to symmetrical logic and exemplify a desirable instruction of Pascal's triangle. This study also suggests a possibility of developing students' unformal and unconscious conception of group with sym metry idea from elementary to secondary school mathematics.

본 논문의 목적은 두 가지이다: 첫째, 구성주의와 사회문화주의의 통합적인 이해를 통해 수학 교사 교육에서 사용할 수 있는 이론적인 잠재성을 토의한다. 둘째, 비고츠키의 사회문화주의에 대한 토의가 그리 많지 않은 상황에서 사회문화주의자들의 주장을 교사교육적 관점에서 설명한다. 학습을 개인적 타원에서 설명하는 구성주의와 학습을 사회적 차원에서 설명하는 사회문화주의는 그 발생 원리상 큰 차이점을 갖는다. 본 논문에서는 이러한 차이점에 대한 논란보다는 어떻게 이 두 가지 이론이 학생들의 수학 학습에서 교사의 역할에 대한 재조명과 이론적 지지 기반을 제공할 수 있는 가능성을 갖는지 다루고 있다.

In this paper, we tried to analyze 7 textbooks for liberal mathematics in elementary teacher's colleges in Korea and 3 foreign textbooks (2 American textbooks and 1 Japan textbook) which are believed to be used for pre-service education. We tried also to analyze in 3 lesson plans in homepages of Japan teacher's colleges. Next we tried to grope for syllabus of Mathematics for Elementary Teachers, and we suggested one syllabus. But we think that syllabus as a tentative one. So, it must be criticized by other researchers to be better one.

Currently most of the educational content to learners to provide more learning opportunities despite the inevitable in terms of its content and format have not only due to the limitations and problems, this alternative to the creation of a new generation of educational content, research is required urgently. In this paper, G-learning content, online games and through the analysis of the type and characteristics is to overcome this problem.

The technical expert standing system of our construction industry is operated by the Ministry of Labor subjective national technical qualification law, as the professional engineer, architect and architect-engineer and so on. The construction management(CM) which is introduced on middle 1990 activates a building industry the condition of the essential indispensability for is becoming, is not officially recognized with is judged as the nostril people for qualification of the civil CM educational institutions ha the certification which is a each educational program and a separate way and it is the actual condition which is become accomplished, In this research, it observes the capital increase reserve problem point which is a domestic CM and the certification integration which is a report and system anger it leads and with national certified qualification it develops to present the improvement program for, it does to sleep.
