Although student-centered teaching practices have been advocated in mathematics education reform, implementing them at the classroom level remains challenging. This exploratory case study examined two unevenly successful student-centered approaches to see how teachers understand and characterize reform, and to articulate issues in implementing reform ideas. The comparison and contrast between the classrooms showed similar classroom social norms but dramatically different mathematical practices. This affords the possibility of exploring the challenges of reform for teachers and other personnel who are attempting to move teaching practices towards the student-centered ideals.

This research is focused on the development of Math teaching and/or learning materials in which the students are centered, not teachers, and which can, in turn, activate and reinforce the students' extra curricular Math activitie The findings I came to have through my research can be summarized as follows: 1. Math teaching and/or learning materials developed based on the students' interactions in the Math extra-curricular activities helped students to learn Math better and to be more interested in Math. 2. There was a positive attitude change toward Math on the side of the students after being introduced in and exposed to Math through the above mentioned Math teaching and/or learning materials. 3. There was a positive attitude change toward Math on the side of the students after being taught Math using the above mentioned Math teaching and/or learning materials. The suggestions I came to have through my research are as follows: 1. There need to be more consistent efforts in developing the Math teaching and/or learning materials which can be used in the Math extra-curricular activities. 2. There need to be more consistent efforts in developing Math teaching paradigms which can be used in Math extra-curricular activities. 3. There need to be more consistent efforts in developing the Math teaching and/or learning materials which can be used in the Math class as well as in Math extra-curricular activities. 4. There need to be more consistent efforts in developing the Math teaching and/or learning materials which are more grade-, unit-, and category-conscious.

The purpose of this study is to discuss about the role of the visualization as an effective method of teaching abstracted mathematics, to analyze visual materials in middle and high school mathematics and to suggest various visualized materials for teaching mathematics effectively. Though formal, symbolic and analytical teaching method is a major characteristic of mathematics, the students should be taught to understand through intuition and insight, and formalize the mathematical concepts progressively. Especially the sight is one of the most important basics of cognition for intuition and insight. Therefore, suggesting mathematical contents through the visual method makes the students understand and formalize the mathematical concepts more easily. In this study, we tried to investigate the meaning and role of visualization in mathematics teaching. And, we discussed about the four roles of visualization in the process of mathematics teaching and learning confirmation and memorization of the mathematical truth, proving theorem and solving problems which is one of the most important purposes of teaching mathematics, According to the roles of visualization, we analyzed visual materials currently taught in middle and high school, and suggested various visual materials useful in teaching mathematics. The investigated fields are algebra where visual materials are little used, and geometry where they are use the most. The paper-made-textbook can't show moving animation vigorously. Hence we suggested visual materials made by GSP and applets in IES .

There were a lot of challenges to reform mathematics education. These challenges may include reforms of teaching and learning methods, development of mathematics curriculum and textbooks, innovative resources for teaching mathematics. Although there is considerable consensus that meeting these challenges will require that mathematics teachers have deep insights about mathematics, about students as learners of mathematics, and about teaching method, the teachers themselves may have little knowledge of them. The most of the professional development includes elective participation in reeducation course, workshop, and special lectures which designed to transmit a specific set of ideas, techniques, or materials to teachers. But such approaches treat mathematics teaching as routine and technical, and also provide limited opportunities for meaningful interactions within the teaching community. So, this paper suggests that what is needed to develop professional teachers of mathematics is community where teachers work with colleagues rather than working alone.

Teaching and learning in schools can be influenced by the ways in which curriculum is understood in terms of its characteristics and range. Viewing curriculum as encompassing all activities pertaining to teaching and learning allows us to examine various aspects of education through curriculum studies. In this respect, this study explores the trends in research on K-12 mathematics curriculum by examining prior studies' research topics categorized into five themes in curriculum studies. In addition, implications for future research are discussed based on the findings of this study.

현재까지 북한의 수학교육에 대한 이해는 문헌분석을 통한 남북 수학과 교육과정 및 교과서의 비교 연구가 주류를 이루어왔다. 이는 북한학교에서 다루어지는 수학 내용에 대한 이해를 가능하게 하나 학교 수업에서 수학을 가르치고 학습하는 방식에 대해서는 거의 알려진 바가 없다. 이에 본 연구에서는 북한에서 이루어지는 수학 수업의 모습을 이해하기 위해 수업환경, 교사의 수업 준비, 북한의 수학과 교수 학습 방법 등을 탐색하였다. 북한의 수업을 직접 관찰하기는 매우 어려우므로 현재 남한에 거주하는 탈북자 중 북한 학교에서 수학을 가르친 경험이 있는 교사를 대상으로 면담을 실시하여 제한적이나마 북한 수학 수업의 모습을 이해하고자 시도하였다. 연구결과 수학수업을 둘러싼 환경과 교사의 준비 과정뿐만 아니라 교수학습 방법 상에도 남북의 차이를 확인할 수 있었다.

창의적 문제해결 능력을 위한 알고리즘 교육의 중요성이 강조되고 있다. 특히 수학 과학과 연계된 논리적 사고력 증진을 위한 알고리즘 교재 개발이 추진 중 이다. 그러나 교육현장에서 적용 가능한 교수-학습 모형에 대한 제시가 미비한 실정이다. 따라서 본 연구는 효과적인 알고리즘 교육을 위한 교수-학습 모형을 제시한다. 나선형 모형으로 학습 진도를 진행하며, 논리적 사고력을 기반으로 하는 알고리즘 교육의 특성을 반영하여 교수-학습 모형을 개발하였다. 또한 학습자의 만족도를 위하여 설문을 실시하였으며, 그 결과로 설계된 교수-학습 모형은 PBL과 자기주도학습 및 동료교수법의 혼합 모형이다. 제시된 모형에 근거하여 수학과 과학의 수업 예시를 구성하여 적용 가능성을 보였다.

최근 수학에 대한 부정적인 학습태도가 초등학생들까지 나타나고 있다. 그러나 초등학생은 수학에 대한 학습태도가 확고히 굳혀졌다기보다는 학습 상황과 주변 여건의 영향을 많이 받는다. 이에 따라 초등학생들의 수학 학습태도를 형성하는 요인을 상황에 따라 구체적으로 조사하고 분석하고 수학 성취도에 따른 주요 요인의 차이를 연구하여 부정적인 수학 학습태도에 대한 해결책 모색과 긍정적인 수학 학습태도를 형성시키는데 시사하는 바를 알아내는데 그 목적이 있다. 초등학생을 대상으로 개방형 설문조사와 면담을 통해 형성 요인들을 분류하여 분석한 후 성취도별 주요 요인을 비교하였다. 그래서 초등학생들은 수학교과 자체 특성보다도 교사의 수학 수업방식에 따라 학습 태도가 좌우되었고, 시험불안의 경우 시험에 대한 부모님의 태도에 의한 것이었다. 그리고 초등학교 학생들도 수학만을 집중해서 가르치는 사교육의 영향이 컸다. 또한 성취도에 따라 주요요인에도 상당한 차이를 보였으며, 특히 성취도 '중'집단의 경우 부모님의 태도 및 학습 환경 등 외적인 요인에 의해 수학 학습태도가 크게 좌우되었다.

The purpose of this study through ethnographic inquiry is to describe how an elementary teacher teaches mathematics with understanding. The ways that teachers'beliefs affect instructional activities, what means understanding from the view of cognitive psychology, and ethnographic research tradition were reviewed to anchor theoretical background of this study. A third-grade teacher and his 45 students were selected in order to capture vivid and thick descriptions of the teaching and learning activities of mathematics. Three major sources of data, that is, participant-observation with video taping, formal and informal interviews with the teacher and his students, and a variety of official documents were collected. These data were analyzed through two phases: data analysis in the field and after the fieldwork. According to data analysis, ‘teaching mathematics with understanding’ was identified as the teachers central belief of teaching mathematics. In order to implement his belief in teaching practices, the teacher made use of three strategies: ⑴ valuing individual student's own way of understanding, ⑵ bring students' everyday experiences into mathematics classroom, and ⑶ lesson objectivies stated by students. It is suggested for future research that concrete and specific norms of mathematics classroom for the improvement of mathematics understanding are needed to be identified and that experienced and skillful teachers' practical knowledge should be incorporated with theories of teaching mathematics and necessarily paid more attention by mathematics educators.

In order to provide pre-service teachers with rich contexts for learning to teach mathematics, teacher education programs usually combine a mathematics methods course with clinical teaching experiences. This paper explores a student-teacher's experience of loaming to teach mathematics by observing one mathematics methods course she was enrolled in and her actual classroom teaching. In particular, this ethnographic case study examines how the student-teacher understands and applies messages from the methods course to her teaching practices. Some differences emerge with regard to ideas and practices. The underlying factors for explaining the gaps are discussed. Finally, this paper provides some implications for pre-service teacher education.
