The purpose of this study is to investigate the degree of anxiety factors for learning mathematics and look into the reason of anxiety of mathematics and show the method of eliminating negative and anxious factors in elementary school, secondary school and high school. To have learner take an interest in learning mathematics, develop the positive attitude about learning mathematics and maximize the effect of learning of mathematics, three kinds of hypotheses are established as follows: 1. There would be difference in anxiety factor of learning mathematics according to elementary school, secondary school and high school. 2. There would be difference in anxiety factor of learning mathematics according to sex. 3. There be difference in anxiety factor of learning mathematics according to the level of achievement. The results of this study are as follows: 1. Hypotheses I was testified. The anxiety factor between mathematics learning and mathematics teacher was significant difference according to elementary school, secondary school and high school. 2. Hypotheses II was testified. The result of hypotheses II was significant difference only in high school. The anxiety factor of mathematics teacher was significant difference according to boy student and girl student. 3. Hypotheses III was testified. The anxiety factor of mathematics, teacher and test was significant difference only in elementary school and high school.

In this note we describe some classes of rings in relation to Abelian property of factorizations by nilradicals and Jacobson radical. The ring theoretical structures are investigated for various sorts of such factor rings which occur in the process.

We continue the study of power-Armendariz rings over IFP rings, introducing $k$-power Armendariz rings as a generalization of power-Armendariz rings. Han et al. showed that IFP rings are 1-power Armendariz. We prove that IFP rings are 2-power Armendariz. We moreover study a relationship between IFP rings and $k$-power Armendariz rings under a condition related to nilpotency of coefficients.

This study was based on the analysis of changes in curriculum of elementary mathematics curriculum, and changes in curriculum of middle school and high school mathematics curriculum. The purpose of this study is to analyze the movement of learning contents among the school levels based on the middle school mathematics curriculum and to summarize the influence on the curriculum of middle school mathematics according to the movement of learning contents. The research conducted according to the purpose of this study is as follows. First, we analyzed the trends of mathematical contents between elementary and middle schools after the movement of ten mathematics curriculums. Second, we analyzed trends of learning factors after mobility and mobility between middle school and high school. Third, the characteristics of 'the contents of mutual movement based on middle school' and 'the contents deleted from middle school' were analyzed. The results of this study are expected to reflect on current and past curriculum and to give meaningful implications to the composition of new curriculum.

Maple is introduced for school mathematics. Many applications of Maple to school mathematics are given in order for teachers to have ideas how to use it. Effects of computer softwares including Maple are also discussed. Some points which teachers have to consider are listed when they use softwares in school mathematics.

In this paper, it is insisted that elementary school mathematics has its own identity, Since it can be found out that is not precisely, rigidly, or deductively developed in elementary school mathematics, it must be regarded as a property of elementary school mathematics. But elementary school mathematics and mathematics as a discipline are not different totally. In this paper, it is stressed that they do not share some attributes of each other.

최근의 고고학적으로 문맥화 된 수학사연구는 인류 초기 문명인 고대 바빌로니아의 학교에서 수학교육이 기능하였다는 사실과 함께 현존하는 가장 오래된 수학인 고대 바빌로니아의 수학적 텍스트가 학교에서 이루어진 교수-학습 과정의 산물(産物)임을 보여준다. 이러한 측면에서 학교수학의 본질과 기능에 대한 탐구의 필요성이 제기되는 바, 본 연구는 교수-학습 과정서 나타나는 산물을 포함하도록 학교수학의 개념을 확장하고 학교수학의 기능에 대한 분석을 시도하였다. 그 결과, 학교수학은 일상생활에서의 수학활동과 학문으로서의 수학의 경계를 명확히 하고 양자를 연결해왔으며 수학적 연습과 준비를 시키는 교육상황(ESMPR)과 수학적 창의성과 오류가 발현되는 교육상황(ESMCE)의 계속되는 연쇄를 통해 작동해온 것으로 파악되었다. 이로부터 본 연구자는 학습에 대한 상반된 두 패러다임인 획득으로서의 학습과 참여로서의 학습은 각각 ESMPR과 ESMCE에 대응하여 상보적으로 작동할 수 있으며 학교수학적 지식의 질적 성장이 Bruner가 말하는 교사와 학생이 형성하는 상호학습 커뮤니티가 Popper의 추측과 반박의 방법을 통해 완성해 나가는 작품으로 이해될 수 있다고 주장하였다.

본 연구는 2022 개정 수학과 교육과정을 앞두고 우리나라의 고등학교 수학과 교육과정과 영국의 고등학교 수학과 교육과정과 비교함으로써 시사점을 제시하고자 한다. 영국은 2017년 이후 16세 이후 수학을 강조하고 평가를 개정하였다. 이에 따라 영국의 고등학교 수학교육과정에 해당되는 Key stage 4, Core Maths, A-level의 내용을 살펴보고, 우리나라 고등학교 공동과목, 일반선택과목, <기하> 과목과 비교하였다. 영국에서는 고등학교 단계에서 수학교육을 강조하고 있는데 이에 따라 교육과정 총론에서 '수리력과 수학'을 강조하고 학생들의 수학 선택권을 확대하고 미래사회를 대비하기 위하여 새로운 수학 교과목 및 평가를 함께 개발하여 시행하고, 기존의 A-level 수학 평가를 개선하였다. 또한 주제 중심의 내용을 Key Stage 3부터 고등학교 단계에서도 발전적이고 지속적으로 다루고 다른 영역의 주제와 연결하여 다룸으로써 수학의 내적 외적 연결성이 용이하도록 구성하고 있었다.

Korean Ministry of Education Science, and Technology(MEST) has recommended the introduction of mathematics textbooks based on storytelling to improve the teaching and learning of mathematics in school. As part of the mathematics textbooks based on storytelling development, this research has investigated school mathematics teachers' perspectives on mathematics textbooks based on storytelling in order to identify implications for the development and the implementation of it. For the purpose, we have developed survey questionnaire and administered it to 113 high school mathematics teachers. The survey asked the teachers to address their conception of mathematics textbooks based on storytelling, its contribution to school mathematics, challenges and obstacles for the implementation. The survey shows that the mathematics teachers' conception of mathematics textbooks based on storytelling was not clear or limited. Most of them replied that they received information about mathematics textbooks based on storytelling from the materials provided by workshop or materials of school district office. While the teachers heard about that school will implement mathematics textbooks based on storytelling, they rarely had idea of how to use them in class. In the survey, the teachers identified which type of storytelling is effective for which purpose of mathematics education. They also identified the positive effect and the difficulties in the implementation of mathematics textbooks based on storytelling. The mathematics teachers pointed out that textbook is not enough. They urged that the implementation of mathematics textbooks based on storytelling should be integrated into classroom teaching and assessment to make a significant change in the educational practice of mathematics in school. Thus, mathematics teachers need support to implement mathematics textbooks based on storytelling into their teaching practice. Teacher workshop and teacher manuals need to be developed to help teachers understand educational visions and values of mathematics textbooks based on storytelling. These results of the survey would form the worthwhile base information for the development and the implementation of mathematics textbooks based on storytelling.

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.
