In this study, we examined some matters related to the learning of variable concept in school mathematics on the basis of the theoretical foundation from the previous studies(e.g. Davis, 1975; Rosnick, 1981; IK chemann, 1981; Wagner, 1983.) and practices on variable concept teaching by evaluating the current state of that. Matters be discussed are as follows; the use of symbol for place holders in elementary mathematics, the dealing with sets those elements are literals and operations of such sets, the teaching of dummy variable, the construction of literal expressions that contains variables, the labeling indeterminates as a constant, the change in the exact meaning of variable according to the function concept, the teaching of a generalization by means of variables. After considering on these matters that are connected with the teaching-learning of variable concept, we suggested the alternative proposal to the current state of variable concept teaching.

This study analyzes the characteristics of elementary math gifted classes through the development and application of teaching and learning materials. We used the guided reinvention methods including quasi-experiential perspectives. To this end, the applicability of Lakatos' quasi-empirical mathematical philosophy in elementary mathematics was examined, and the criteria for the development of teaching and learning materials for gifted students were presented, and then this study was conducted in this theoretical background. The subjects of the study were 21 elementary students at P University's Institute of Science and Gifted Education, and non-face-to-face real-time classes were conducted. Classes were divided into introduction, deployment1, deployment2, organization stages, and in each stage, small group cooperative learning was conducted based on group activities, and in this process, the characteristics of elementary mathematics gifted were analyzed. As a result of the study, elementary mathematics gifted students did not clearly present the essence of justification in the addition algorithm of fractions, but presented various interpretations of 'wrong' mathematics. They also showed their ingenuity in the process of spontaneously developing 'wrong' mathematics. On the other hand, by taking interest in new mathematics starting from 'wrong' mathematics, negative perceptions about it could be improved positively. It is expected that the development of teaching and learning materials dealing with various and original topics for the gifted students in elementary school will proceed through follow-up research.

본 논문은 수학 교사 학습과 전문성 신장에 관한 보다 종합적이고 체계적인 이해를 증진하기 위한 노력의 일환으로, 우선 교사 학습을 이해하기 위한 다양한 이론적 틀을 검토하고 교사 학습과 관련하여 지식과 교수 관행간의 관계를 조사하며 탐구 공동체를 중심으로 한 효율적인 전문성 신장에 관한 아이디어를 분석한다 이와 같은 이론적 분석에 터해 교사 학습과 이에 관련한 수학교실문화의 변화 과정을 연구하는 프로젝트를 간단히 소개하고 탐구 공동체의 운영, 교사의 관점에서 교수 관행을 기술하는 것, 공동체에서의 교사 학습을 분석하는 것 등 프로젝트를 수행하면서 부각되는 문제점에 대해 논의한다.

수학은 오랜 역사를 가진 학문으로 수학으로부터 새로운 학문이 발생하기도 하고 다른 학문과의 관련을 계속 이어왔기에 수학과 타 교과 통합 교육은 수학의 학문적 특성에 비추어 자연스러운 시도라 할 수 있다. 그렇지만 과학 과목의 주제를 수학의 학습 소재로 다루는 시도 외에 타 교과와 통합을 통한 수학 교육 연구는 별로 이루어지지 않았다. 본고에서는 수학과 타 교과 통합 교육의 유형과 통합 교육에 대한 국내 연구 동향을 살펴보고 고등학교 수학 교과와 사회 교과의 통합 교수-학습자료를 중심으로 하여 수학과 타 교과와의 통합 교수-합습자료를 문헌연구를 통하여 알아보았다. 그 결과, 수학의 유용성에 대한 인식 제고 및 흥미도 향상에 도움을 줄 수 있도록 수학과 과학 또는 수학과 사회 외에도 예술, 체육, 국어 교과와의 통합 자료도 최근 개발되었음을 알 수 있는데, 이에 대한 수정 보완에 대한 연구는 본고를 토대로 하여 앞으로 더 수행되어야 할 것이다.

A research group consisting of some mathematics education scholars and school teachers has been formed to build a website which intended to combine both theories and practices of mathematical teaching since 2002. There were three working stages: video-tapping realistic math teaching, developing video discs of different themes, and designing e-Learning. The group members learned knowledge of teaching by actual participating. On the other hand, the products enabled the audience to get professional development in knowledge of both mathematics and teaching. Management process of this group and effects upon the participants and users will be presented and discussed in this paper.

This study investigated the effect of teaching mathematical communication in mathematics learning. Cooperative learning, mathematics pin pals, and writing a mathematics diary were used to teach how to communicate mathematically. The experimental group was assigned to cooperate in class, to write a mathematics diary at the end of each class, and to exchange the mathematics pen pals once a week. The control group was taught by the traditional teaching method. The results were analyzed quantitatively and qualitatively. The learning achievement between the two groups was performed with pretests and posttests. And after this study, mathematics pen pals, video protocol and open-ended test were analyzed. The results of this study are the following: 1. There were little differences in learning achievement test between the group taught through communication and those not. And there were little differences in the results of achievement test between the two groups-high and low level classes.2. Cooperative learning, writing a mathematics diary and mathematics pen pals were effective as methods of teaching communication mathematically. The analysis of mathematics pen pals which is to investigate student's writing abilities showed that pen pal partners were improved in QCAI communication levels. There was a significant difference between the two groups in open-ended test. This means that communication learning has an effect on the tests for mathematical thought, reasoning, and creative thought. The analysis of video protocol showed that four students in a cooperative group were improved in their speaking and listening abilities.

이 논문은 수학 교사의 신념과 지식이 수학 수업에 어떻게 표현되는 지 미국 중학교 수학 교사의 수업 분석을 통한 사례연구 보고서이다. 미국 중학교 수학 교실에서 이루어지는 수업에 대한 정보를 제공할 뿐만 아니라, 수학교사의 신념과 지식이 수업에 어떻게 반영되고 적용되는지 상세하게 분석 설명한다. 사례 분석 연구 결과는 참여 수학 교사의 수학 교수학습에 대한 신념체계가 수업에 일정 정도 일관성 있게 표현됨을 보여 준다. 특히, 그 교사의 신념체계가 수학 수업을 조직하고 구성하는데 큰 영향을 미치는 것으로 나타났다.

This study aimed to understand the needs of changes in the teaching-learning environment in the university and to develop the liberal art subject of mathematics. The changes of mathematical belief in the university students were investigated to understand how the liberal art subject of mathematics affected them related to mathematics. Upon the study results, the significant changes were occurred from the utility factor on the subject of mathematics in mathematical belief, the importance factor of the answers in the teaching-learning belief, teaching activity factor of the teachers, and inborn capability factor in the belief on the self-concept. The meaningful learning environment and teaching method for the liberal art subject of mathematics are suggested further by these results.

This study is on the use of mathematics program for School Mathematics Education. According to the ‘technology principle’ by NCTM and teaching-learning methods by the 7th curriculum, we developed mathematics learning activities with mathematics program. This activity is to construct designs with graphs by using mathematics program(GrafEq.). In this study, we practiced these learning activities with pre-service mathematics teachers. The mathematics educational effects of these learning activities in this study are analyzed as follows; active & spontaneous search for mathematical knowledge, the experience of problem solving, affirmative view-point of mathematics, understanding of practical use of mathematics, acquisition an interest & motivation of learning mathematics etc. When students learn graphs of function, the concept of inequality in secondary school mathematics class., mathematics teachers can make a good use of constructing designs by mathematics program(GrafEq.). This will help to practice of teaching-learning methods by the 7th curriculum.
