구성주의 관점에 의하면 수학적 지식은 교사가 일방적으로 전수하는 것이 아니라 학생들이 자발적인 방법으로 스스로의 지식을 형성해 가는 것이다. 특히 사회적 구성주의에서는 사회구성원간의 의사소통을 통해 수학지식이 형성됨을 강조하고 있다. 일반적으로 학생들의 의사소통은 소집단 협동학습의 환경에서 가장 활발하게 이루어진다. 문제해결을 위해 학생들은 각자의 생각을 교환하고 자유롭게 질문하며 상호간의 사고와 개념을 명확하게 하고 의미 있는 방법으로 서로의 학습에 도움을 주게 된다. 본 연구에서는 6학년 학생들이 수학적 논의를 하는 과정에서 사용하는 의사소통의 수단을 언어와 행동의 관점으로 분석하여 매 수업 장면에서는 관찰하기 어려운 소집단 협동학습 내의 집단적인 역학관계를 파악하고자 한다.

The purpose of this study was to explore status of mathematical interactions between parent and child and use of mathematical materials at home. For this purpose, questionnaires were developed. The framework of the questionnaires consisted of mathematics education content domains. 276 parents(4-5 year old children) in J Province responded to the questionnaires, which were analyzed according to the level of home income, the mother's work conditions and the mother's level of education. The results were as follows: First, between parent and child mathematical interaction at home showed a 2.84 score in average and frequency of mathematical interaction expressed in the domains of 'Understanding of regularity', 'Measurement', 'Growing number sense', 'Space and shapes', 'Organizing data and showing results'. The domains of 'Growing number sense', 'space and shapes', and 'measurement' showed significant difference only by mother's level of education. The higher the mother's level of education, the more frequent the mathematical interaction between parent and child. Second, the use of mathematical materials showed an average score of 1.18, which means mathematical materials were practically not used at home. Also, the use of mathematical materials showed a slightly significant difference when measures against the levels of home income and the mother's level of education. The results showed a significant difference in parent-child mathematical interactions, and the possession and use of mathematical materials when measures against by level of home income and the mother's work conditions. Therefore, the results of this study suggest that the parent education program for mathematical interaction to apply at home and mathematics curriculum to be connected early in childhood education institution and home should be developed for parents.

본 연구는 우리나라 학생들의 수학적 신념을 간편하게 측정할 수 있는 표준화된 측정 도구를 문헌연구와 심리측정학적 분석을 바탕으로 수학교과에 대한 신념, 수학 문제해결 신념, 수학 교수 학습에 대한 신념, 수학적 자아개념의 4개의 하위 요소로 구성하여 중학생용은 총 37문항으로, 고등학생용은 총 40문항으로 개발하였다. 그리고 대단위 표집 검사를 실시하여 우리나라 중 고등학생의 수학적 신념이 학교급별, 성별, 성취수준에 따라 어떤 특성이 나타나는지를 분석하였다. 연구 결과, 중 고등학교 모두 남학생이 여학생보다 수학이 유용하다고 믿는 신념, 수학에서 과정보다 정답을 구하는 것이 중요하다고 믿는 신념, 많은 수의 문제를 푸는 것이 중요하고 믿는 신념 등이 강하게 나타났고, 중학교에서 고등학교로 진급하면서 수학적 자아개념 중 '감정' 요인이 긍정적으로 변화하였다. 여학생은 중 고등학교 모두 수학 교수 학습에 대한 신념 중 '교사의 수업활동' 요인만이 남학생보다 강하였다. 성취수준이 '기초이하' 집단 학생들이 수학은 암기해야 하는 공식과 절차라거나 창의적 활동에 대한 기회를 제공하지 못한다고 생각하는 '고정관념'이 가장 강하였다. 그 외요인에서는 '우수' 집단 학생들의 신념이 강하였다.

This study reviewed the notion and strategies of mathematical creativity from two point of view, mathematics and creativity. By these reviews, the spectrum was presented as frame of mathematical creativity task. Creativity and mathematics were seen as polar opposites and mathematical creativity task fit clearly at various points in this spectrum. Some focused on the quantity of ideas and originality from creative point of view. On the other hand, some focused on reasoning, insight, and generalization from mathematical point of view. The tasks on the spectrum were served as the vehicle of mathematical creativity and mathematics classroom. Therefore, there were some specific suggestions that mathematics classroom could be made a place where students and teachers would be able to foster their mathematical creativity.

Recently, mathematical modeling has been attractive in that it could be one of many efforts to improve students' thinking and problem solving in mathematics education. Mathematical modeling is a non-linear process that involves elements of both a treated-as-real world and a mathematics world and also requires the application of mathematics to unstructured problem situations in real-life situation. This study provides analysis of literature review about modeling perspectives, case studies about mathematical modeling, and textbooks from the United States and Korea with perspective which mathematical modeling could be potential and meaningful to students even in elementary school. Further, teaching method with mathematical modeling was investigated to see the possibility of application to elementary mathematics classroom.

This paper considers learning and teaching of mathematical analysis in teachers college. It concentrates on showing a way how learning and teaching of mathematical analysis should be considered for mathematical teachers training. It is composed of five chapters including Chapter I as an introduction and Chapter Vasa concluding remarks. Chapter II deals with goal and contents of global mathematical analysis. The main Chapter, named Chapter III, demonstrates exhibition of contents, way of operations, and contents of teaching and learning of mathematical real analysis. Chapter IV shows an example of learning and teaching of mathematical real analysis concerning to fixed points and approximate solutions.

In this study, the instrument of mathematical problem posing ability and mathematical creativity ability tests were considered, and the differences between gifted and regular students in the ability were investigated by the test. The instrument consists of each 10 items and 5 items, and verified its quality due to reliability, validity and discrimination. Participants were 218 regular and 100 gifted students from seventh grade. As a result, not only problem solving but also mathematical creativity and problem posing could be the characteristics of the giftedness.

The purpose of this study was to examine and analyze the cognitive demand of the mathematical tasks suggested in the middle school textbooks. In particular, it aimed to reveal the overall picture of the level of cognitive demand of the mathematical tasks in the strand of geometry in the textbooks. We adopted the framework for mathematical task analysis suggested by Stein & Smith(1998) and analyzed the mathematical tasks accordingly. The findings from the analysis showed that 95 percent of the mathematical tasks were at high level and the rest at low level in terms of cognitive demand. Most of the mathematical tasks in the textbooks were algorithmic and focused on producing correct answers by using procedures. In particular, the high level tasks were presented at the end of each chapter or unit for wrap up rather than as key resources.

This study was aimed to examine problem-solving ability of fifth graders on two types of mathematical essay problems, and to analyze the process of mathematical justification in solving the essay problems. For this purpose, a total of 14 mathematical essay problems were developed, in which half of the items were single tasks and the other half were data-provided tasks. Sixteen students with higher academic achievements in mathematics and the Korean language were chosen, and were given to solve the mathematical essay problems individually. They then were asked to justify their solution methods in groups of 4 and to reach a consensus through negotiation among group members. Students were good at understanding the given single tasks but they often revealed lack of logical thinking and representation. They also tended to use everyday language rather than mathematical language in explaining their solution processes. Some students experienced difficulty in understanding the meaning of data in the essay problems. With regard to mathematical justification, students employed more internal justification by experience or mathematical logic than external justification by authority. Given this, this paper includes implications for teachers on how they need to teach mathematics in order to foster students' logical thinking and communication.

근래 수학의 학습에서 수학의 내용뿐만 아니라 수학적 과정을 평가할 수 있는 문항의 중요성에 대한 인식이 확산되고 있다. 본 연구에서는 수학의 내용과 더불어 수학적 과정 즉, 수학적 의사소통, 추론, 문제해결을 명시적인 평가요소로 포함하는 서술형 문항으로서 '수학적 과정 문항'이라는 개념을 제안하고, 수학적 과정 문항의 제작을 위한 예시 평가기준과 문항 및 채점기준 개발을 통해 서술형 문항을 활용한 수학적 과정 평가 방안을 논의한다.
