The purpose of this study is to examine the effects of taking a 「Theory of mathematical education」 on the mathematical beliefs of pre-service teachers. For this theory of mathematical education was run in the first semester of 2021 and 2022, and the data was collected and analyzed by conducting a mathematical beliefs questionnaire, drawing a mathematics class scenes test, and focus group interviews with participants. According to the results of the study, there was a statistically significant difference between the pre-test and post-test results on the 'process of inquiry' of the nature of mathematics and the 'active participation' of mathematics learning in the mathematical belief category of pre-service teachers. In addition, in the image test of mathematics classes, the proportion of the image of the student-centered class increased significantly in the post-test compared to the pre-test, while the proportion of the image of the teacher-centered class decreased significantly. It can be assumed that the various learning opportunities provided in the pre-service mathematics teacher education program promoted the composition of practical knowledge based on propositional knowledge of pre-service teachers, and this series of processes contributed to transforming the mathematical beliefs of pre-service teachers into learner-centered beliefs.

Algebraic signs are important on learning and problem solving of algebra. This study investigated the contents of letters and expressions in textbooks by syntactics, semantics and pragmatics, and considered the introduction and extension processes of algebraic signs didactically. We also categorized the signs, and looked into textbook problems in view of semiotic. The result is that textbook is constructed in syntactics and semantics. Finally, the assessment of 7th grade students' competence in syntactics, semantics, syntactics+- semantics, pragmatics, and problem solving shows that students' ability in syntactics and pragmatics Is a predictive variable for algebraic problem solving.

This study explores classes for pre-service mathematics teachers. The purpose of this study is to examine the differences between 'non-face-to-face' classes & 'face-to-face' classes, as well as the differences in learning outcomes between these two methods. A Professors' Learning Group was formed to effectively carry out this study. Through this learning group, we shared how to plan and operate the lecture. The subjects of this study are 'non-face-to-face calculus courses & face-to-face calculus courses' and 'non-face mathematics education theory courses & face-to-face mathematics education theory courses." Specifically, in these two pairs of courses, we analyze the differences in course management and the differences in the outcomes of students' assessments. Non-face-to-face classes were planned, developed, implemented and evaluated based on the 'non-face class design model.' The results of this study are as follows: First, we explored the differences between 'non-face-to-face classes/mixed classes' and 'face-to-face classes.' Second, the achievement results in calculus courses were higher in face-to-face classes than in non-face classes. Third, the results of achievements in mathematics education theory courses were higher in mixed classes than in face-to-face classes. Through the results of this study, we hope that the non-face-to-face class capabilities can be improved in pre-service mathematics teacher training.

Recently, there have been many changes in researches of mathematics education. There is a growing number of researchers who are interested in empirical researches. According to the these changes, there is also an emphasis on methodology of mathematics education. This means that many researchers try to conduct an research using scientific approach. Therefore, new types of research developing mathematics courses recently has evolved as follows: teaching experiment, hypothetical loaming trajectory, design science, developmental research. The aim of this study is to reflect on developmental research in RME and to induce desirable directions for developing our mathematics courses. In order to attain these purposes, the present paper reflects the philosophy of RME, aim, procedure, data collection, data analysis, and justification of developmental research with illustrating a exemplar Based on these reflections, it is discussed that it needs to construct the mathematics curriculum connecting theory and practice in mathematics education, to report the process of developing mathematics courses faithfully, and to develop real mathematics courses after conducting basic developmental researches in order to take scientific app- roaches for developing mathematics courses.

7차 교육과정을 시행에 앞서, 현재 초등학생들이 수학을 어떻게 생각하고 있으며, 어 떤 이유로 수학에서 학습 부진을 느낄까? 라는 문제의식을 갖게 되었다. 그래서 정규교육의 첫 단계인 초등학교 수학교과에 대한 인식 및 학습 부진에 관한 연구를 시행하고자 했다. 본 연구대상은 대전 ${\cdot}$ 충남 지역에 소재하고 있는 6개 초등학교 6개 반을 선정하여 발달사고과정에서 자신의 생각을 분명하게 나타낼 수 있는 4학년에서 6학년을 연구대상으로 선정하여 교과요인에 대한 설문조사를 하였다. 본 연구는 수학교과에 대해초등학생들이 어떤 생각을 가지고 있고, 어떤 교과요인을 학습하는데 어려움을 느끼는지를 알아봄으로써, 본 연구 결과를 기초로 중학생 ${\cdot}$ 고등학생 ${\cdot}$ 대학생들까지 연속하여 수학교과에 대한 인식을 조사하고 함이며, 새롭게 시행될 7차 교육과정에서의 수학교과 구성면과 수학 학습 및 교수 방법론에 보다 바람직하고 효과적인 시사점을 제공하고자 한다.

1960년대를 기점으로 하여 일어난 수학 교육현대화 운동은 범세계적인 문화현상으로서 발전하는 방향으로 철저히 진행되어야 했으나 교재내용을 지나치게 비현실적으로 도입함에 따라 교육의 현장에 선교사의 창조적 노력보다는 무비판적인 수학교육이 됨으로써 원래의 수학교육목표와는 달리 진도에만 급급하다. 현실적인 요인으로서 중등학교 진학률의 증가 및 평준화에 대한 원인도 있겠지만 시험에만 연결되는 교육에 이상적인 논리주의 구조주의 적인 수학의 도입도 적지않은 문제 요인으로 되어 있다. 앞으로 교과과정의 개선이 있겠지만, 우선 지도방법에 있어서 새로운 방법론이 시도되어야 할 것이다. 본 논문에선 학생들이 이해할 수 있는 범위내에서 수학사적 자료를 도입하여 수학의 역사 및 수학의 사상적 배경등에 접할 수 있는 기회를 주어 교과내용에 흥미를 유발하고 수업내용을 이해하는데 도움을 주는 방법을 모색하려는 것이다.

본 연구의 목적은 예비 초등교사의 덧셈과 뺄셈에 대한 교과 지식과 교수학적 지식이 어떠한가를 알아보는 것이었다. 29명의 예비 초등교사가 연구에 참여하였으며 자료는 개방형 답을 하는 질문지를 사용하여 수집하였다. 분석결과 예비 초등교사들은 문장제에서 의미론적 구성과 합병과 구차의 상황에 대한 이해에 어려움을 가지고 있는 것으로 나타났다. 교수학적 방법에서는 알고리즘에 의한 설명 방법을 주로 사용하였으며 뺄셈을 설명하는데 몇 가지 오개념을 보였다. 이 결과는 앞으로 초등교사양성대학의 프로그램 개발과 운영에 기초가 될 것이다.

This study is to explore the directions for developing the lesson assessment of the math textbook in elementary school level, which is to embody the recent trends of math assessment and the emphases about assessment given in the revised 2009 math curriculum. To this end, we examined the recent trends of math assessment and the assessment framework of RME (Realistic Math Education) as the theoretical backgrounds. Also we analytically looked at the math-assessment emphases given in the revised 2009 math curriculum, and tried to establish the directions for developing the lesson assessment of the math textbook on the basis of the preceding studies. In addition to, we gave the math items in line with the established directions about lesson assessment. Finally we suggested the issues in relation with the math assessment in the elementary school level.

The purpose of this study is to analyze 'datum' of 'The Data' in the textbooks of middle school on the basis of 'The Data of Euclid' and develop datum. For this, the followings are conducted. First, the distinctive structure of datum of 'The Data' is considered. Second, some learning materials the contents of geometry in the textbooks of middle school are analyzed and the mathematical meanings are explored. Third, the applicable datum to geometry education of middle school are developed and the way of educational use is studied. The hopefully, the result of this study will make school mathematics education more plentiful and give meaningful implications to revision of mathematics education curriculum and the improvement of teaching and learning.

This study explores the characteristics and roles of non-textual elements in secondary mathematics textbooks in the United States and South Korea, using a conceptual framework that I have developed: variety, contextuality, and connectivity. Analyzing five U.S. standards-based textbooks and 13 Korean textbooks, this study shows that although non-textual elements in mathematics textbooks are free of literal language, they exhibit different emphases and reflect assumptions about what is important in learning mathematics and how it can be taught and learned in a particular societal context (Mishra, 1999; Zazkis & Gadowsky, 2001). While there are similar patterns in the use of different types of non-textual elements in textbooks from both countries, different opportunities are provided for students to learn mathematics between the two countries.
