Under the assumptions that teachers' beliefs toward mathematics education play a role of a filter between teachers' knowledge and teaching practices, this study surveyed and analyzed elementary teachers' beliefs toward mathematics education: helping students to understand mathematics concepts, addressing students' mathematical misconceptions, engaging students in mathematics classroom, and improving students' mathematical thinking. From the analysis of survey results of the study, I found that there were dominant components in elementary teachers' beliefs system regarding teaching mathematics. In addition, there are some constructs affected by teachers' characteristics such as gender and educational backgrounds. In this study, I presented a representative model of elementary teachers' beliefs system toward mathematics education.

The purpose of this study was to investigate the effects of communication - oriented mathematical writing strategies on students' mathematics achievement and mathematical propensity. In order to achieve the purpose, three types of communicative math writing learning strategies such as writing their own thoughts and feelings, writing problem solving process, and explaining the mathematical concepts. In the comparative group, general lessons based on textbooks and tutorials were conducted. As the results, the students in the experimental group showed a significant improvement in mathematics achievement and a positive effect on the mathematical propensity as compared with the comparison group.

The purpose of this study is to explore how elementary mathematics teachers' adaptations of a reform-oriented mathematics curriculum material in the USA, Everyday Mathematics, influence elementary students' opportunities to learn mathematics. I illustrate how elementary mathematics teachers alter the curriculum material and how such alterations influence their students' opportunities to learn mathematics in their mathematics classrooms. Results suggest that the teachers with Everyday Mathematics did not appear to maintain the cognitive demand of mathematical tasks as appeared in the curriculum material, as set up by the teacher, and as enacted in the classrooms. The results also show that the teachers seemed to omit components including important tasks and suggestions in the curriculum material. As a consequence, the students did not have an opportunity to think and understand mathematics conceptually and meaningfully; they were exposed and encouraged to learn mathematics procedurally.

The purpose of this study is to investigate the educational significance of STEAM in school mathematics education by developing a STEAM program that learns mathematical and scientific principles based on patterns and analyzing the effects of developed program. For this purpose, we conducted an experimental class based on the STEAM program developed. STEAM attitude and satisfaction were tested for 120 elementary school students. The results of this study are as follows. First, in terms of STEAM attitude, STEAM-based experimental instruction did not differ significantly in the second grade students. However, there were positive effects in the other five grades. Second, in terms of satisfaction, the proportion of students who were 'generally' was 89%. the proportion of students who were 'not generally' was 3%. Study subject students were found to be generally satisfied with the STEAM-based instruction.

In this study, we conducted the survey to 116 SENKs (students who emigrated from North Korea to South Korea) about mathematical attitude and recognition on mathematics learning and mathematics lesson in South Korea. As the results of the study, SENKs' had positive index on mathematical attitude and recognition about mathematics lesson, but negative index on the recognition about their mathematics learning. SENKs' showed the favoring pictures about mathematics lesson and the needed supports for improving their mathematics understanding. Based on the results, we discussed the implications for teaching and learning of SENKs.

The purpose of this study was to examine the metacognition of mathematically gifted students in the problem-solving process of the given task in a bid to give some significant suggestions on the improvement of their problem-solving skills. The given task was to count the number of regular squares at the n${\times}$n geoboard. The subjects in this study were three mathematically gifted elementary students who were respectively selected from three leading gifted education institutions in our country: a community gifted class, a gifted education institution attached to the Office of Education and a university-affiliated science gifted education institution. The students who were selected from the first, second and third institutions were hereinafter called student C, student B and student A respectively. While they received three-hour instruction, a participant observation was made by this researcher, and the instruction was videotaped. The participant observation record, videotape and their worksheets were analyzed, and they were interviewed after the instruction to make a qualitative case study. The findings of the study were as follows: First, the students made use of different generalization strategies when they solved the given problem. Second, there were specific metacognitive elements in each stage of their problem-solving process. Third, there was a mutually influential interaction among every area of metacognition in the problem-solving process. Fourth, which metacognitive components impacted on their success or failure of problem solving was ascertained.

본 연구는 확률의 다양한 의미를 반영한 초등학교 확률 학습 프로그램을 개발하고, 개발된 프로그램의 적용 가능성을 알아보는데 목적을 두고 있다. 먼저 확률의 다양한 의미를 반영한 초등학교 확률 학습프로그램을 개발하기 위하여, 프로그램의 기본 방향을 설정하고, 확률의 다양한 의미를 반영하기 위한 교수 방법을 마련하였다. 개발된 프로그램은 초등학교 6학년 한 단원 분량인 7차시로 이루어져 있다. 다음으로 프로그램 시행 전에 실시한 검사에서 확률적 사고 수준이 상 ${\cdot}$ 중 ${\cdot}$ 하인 것으로 나타난 세 명의 학생을 연구 대상으로 개발된 프로그램을 시행하였다. 프로그램 적용 전 ${\cdot}$ 후에 실시한 지필 평가와 비디오 카메라로 녹음한 수업 내용과 학생들의 학습지를 검토하여 프로그램 적용 전, 1${\sim}$7 각 차시 후, 프로그램 적용 후의 시기로 나누어 분석한 결과, 세 학생 모두 확률적 사고 수준이 가장 높은 수준인 4수준으로 발전하였다. 본 연구의 결과, 확률을 이론적 의미 뿐 아니라 경험적 ${\cdot}$ 통계적 의미로 접근하면 초등학교 학생들도 확률 개념을 학습할 수 있었다. 따라서 확률을 다양한 관점으로 접근한다면, 초등학교에서도 독립성, 조건부 확률 같은 개념을 유의미하게 학습할 수 있을 것이다.

The statement, 'Taking more mathematics would result a better mathematics teacher.' sounds plausible. However, it is questionable that how much of taking university level of mathematics such as abstract algebra and real analysis would affect to teach elementary mathematics well. Would a mathematician be a better teacher for elementary students to teach mathematics than who has been prepared to teach elementary mathematics? This paper reports the effects of opportunities to learn tertiary level mathematics and school level mathematics on pre-service primary school teachers' mathematics pedagogical content knowledge. The study analyzed Teacher Education and Development Study in Mathematics 2008 (TEDS-M 2008) database using multiple regression. Prospective primary teachers who have been prepared as generalist were the focus of the study. The results support future elementary teachers might need to have opportunities to revisit school mathematics they are going to teach.

This study is a complex type consisting of survey study and self-study. The former investigated elementary teachers' epistemological beliefs on convergence knowledge and teaching. As a representative of the result of survey study I, as a teacher as well as a researcher, was the participant of the self-study, which investigated my epistemological belief on convergence knowledge and teaching and my execution of convergent science teaching based on family resemblance of mathematics, science, and physical education. A set of open-ended written questionnaires was administered to 28 elementary teachers. Participating teachers considered convergent teaching as discipline-using or multi-disciplinary teaching. They also have epistemological beliefs in which they conceived convergence knowledge as aggregation of diverse disciplinary knowledge and students could get it through their own problem solving processes. As a teacher and researcher I have similar epistemological belief as the other teachers. During the self-study, I tried to apply convergence knowledge system based on the family resemblance analysis among math, science, and PE to my teaching. Inter-disciplinary approach to convergence teaching was not easy for me to conduct. Mathematical units, ratio and rate were linked to science concept of velocity so that it was effective to converge two disciplines. Moreover PE offered specific context where the concepts of math and science were connected convergently so that PE facilitated inter-disciplinary convergent teaching. The gaps between my epistemological belief and inter-disciplinary convergence knowledge based on family resemblance and the cases of how to bridge the gap by my experience were discussed.
