The purpose of this research is to analyze the textbook contents about the natural number concepts in the Korean National Elementary Mathematics Curriculum. Understanding a concept of natural number is crucial in school mathematics curriculum planning, since elementary students start their basic learning with natural number system. The concepts of natural number have various meaning from the perspectives of pedagogical research, and the philosophy of mathematics. The natural number concepts in the elementary math curriculum consist of four aspects; counting numbers, cardinal numbers, ordinal numbers, and measuring numbers. Two research questions are addressed; (1) How are the natural number concepts focusing on counting, cardinal, ordinal, measuring numbers are covered in the national math curriculum? ; (2) What suggestions can be made to enhance the teaching and learning about the natural number concepts? Findings reveal that (1) the national mathematics curriculum properly reflects four aspects of natural number concepts, as the curriculum covers 50% of the cardinal number system; (2) In the aspect of the counting number, we hope to add the meaning about 'one, two, three, ......, and so on' in the Korean Mathematics curriculum. In the ordinal number, we want to be rich the related meaning in a set. Further suggestions are made for future research to include them ensuing number in the curriculum.

오늘날 수학교육에 있어서 가장 중요한 문제 중 하나는 학교수학의 인간교육적 기반을 회복하는 것이며, 이를 위해서는 '수학을 가르치는 이유는 무엇인가'라는 보다 근원적인 문제에 대한 논의가 새롭게 요구된다. 본 논문은 생활의 문제 해결이나 과학 기술을 위한 유용한 도구적 지식교육을 지향하는 오늘날 수학교육에 대한 문제 의식에서 출발한다. 먼저 '마음의 중층구조 이론에 비추어 이론적 지식 중심의 수학교육의 의미를 분석적으로 논의하고, 과거 교육사상사에서 수학교육이 어떤 인간교육적 이념을 추구해 왔는지를 Platen과 Froebel의 교육론을 통해서 살펴보았다. 그리고 20세기 초수학교육 개혁운동을 선도하여 현대의 수학교육 천학 및 수학 교육과정의 기본바탕을 제시한 F. Klein의 수학교육론을 고찰하였다. 특히 Klein의 수학교육 사상의 이면을 보다 명확히 드러내기 위하여, '마음의 중층구조'에 비추어 그의 수학교육론을 심성함양이라는 측면에서 재음미하였다. 또한 Klein의 수학교육 이념에 대한 보다 발전적인 논의를 위하여 Klein 이후 수학교육 발전과정에서 드러난 몇 가지 연구결과를 종합하여 심성함양으로서 '함수적 사고' 교육에 대한 발전적 고찰을 시도하였다. 이상과 같은 고찰을 통해 실용적 가치 추구로만 여겨졌던 오늘날의 수학 교육과정의 이면에 심성함양으로서의 인간교육적 가치가 핵심을 이루고 있으며, 수학교육은 그러한 가치 추구를 중시함으로써 심성함양에 기여해야 함을 논하였다.

The purpose of this study is to see what the essential characteristics are in teaching probability and statistics among various mathematical fields. we also tried to connect the study of probability and statistics education with what is needed for a science be synthetic to have its own identity as a unique research field. Since we searched for the future direction of the pedagogic study in the probability and statistics we first selected papers on probability and statistics published in (Series A), the Journal of Korea Society of Mathematical Education, and establish the following research questions. What kinds of characteristics can be found when papers on probability and statistics published in (Series A) are classified into low categories; contents of probability and statistics education, research method of the mathematics education, methods of teaming and teaching, and finally measurements and evaluation\ulcorner We classified papers into two kinds. One is related to the educational contents, consisting of the methods of learning and teaching, and of the measurement and evaluation. The other is reined to the methods of research, which is not a part of the educational curriculum but is essential for establishing the identity of mathematics education. According to the periods, papers on the curricular contents in 1960s were influenced by the New Mathematics, and papers on the curricular contents in 1980s were influenced by 'back to basic'. In 1990s, papers on methods of learning and teaching, and measurement md evaluation were increasing in number. Besides, (series A) from the Journal of Korea Society of Mathematical Education covers contents, methods of Loaming and teaching, and measurement and evaluation. And when I examined the papers on the contents of textbook of a junior high school related to the probability and statistics education and on methods of learning and teaching, 1 found that those papers occupy 1.84% in . When it comes to the methods of loaming and teaching, most of studies in (series A) are about application of concrete implement like experiment and practical application of computer programs, Through this study, I found that over-all and more active researches on probability and statistics are required and that the studies about methods of loaming and teaching must be made in diverse directions. It is needed that how students recognize probability and statistics, connection, communication and representation in probability and statistics context, too. (series A) does not have papers on methods of study. Mathematics pedagogy is a mixture of various studies - mathematical psychology, mathematical philosophy, the history of mathematics and Mathematics. So If there doesn't exist a proper method of study adequate in the situation for the mathematics education the issue of mathematics pedagogy might be taken its own place by that of other studies'. We must search for the unique method of study fur mathematics education so that mathematics pedagogy has its own identity as a study. The study concerning this aspect is needed.

비트겐슈타인의 "논리-철학 논고"에서 "연산 이론"은 "논고"의 수학 철학의 핵심적 토대다. 비트겐슈타인은 연산 이론을 바탕으로 6.02에서 기수의 정의를 제시하고 있고, 6.241에서 연산 이론을 이용하여 "$2{\times}2=4$"의 증명을 제시한다. 그렇기 때문에 "논고"의 수학 철학을 정확하게 해명하기 위해서는 "논고"의 연산 이론에 대한 철저한 이해가 요구된다. 그리하여 나는 이글에서 "논고"의 수학 철학을 해명하기 위한 예비적인 작업으로서 "논고"의 연산 이론을 해명하고자 한다. 이러한 과정에서 우리는 6.241에 대한 프래스콜라의 재구성과 해석에서 그의 중요한 기여와 오류들을 확인할 수 있다. 특히 우리는 6.241에서 비트겐슈타인이 실수를 하게 된 배경과 그가 6.241에서 연산이론의 덧셈 연산을 다루었다는 것을 이해할 수 있고 이를 토대로 6.241을 올바르게 재구성할 수 있다.

Realistic Mathematics Education (RME) focuses on guided reinvention through which students explore experientially realistic context problems to develop informal problem solving strategies and solutions. This research applied this philosophy of RME to design a differential equation course at a university level. In particular, the course encouraged the students of the course to use numerical methods to solve differential equations. In this context, the purpose of this research was to describe the developmental process in which the students constructed and reinvented Euler algorithm in the class. For the purpose, this paper will present the didactical principle of RME and describe the process of developmental research to investigate the inferential process of students in solving the first order differential equation numerically. Finally, the qualitative analysis of the students' reasoning and use of symbols reveals how the students reinvent Euler algorithm under the didactical principle of guided reinvention. In this research, it has been found that the students developed deep understanding of Euler algorithm in the class. Moreover, it has been shown that the experience of doing mathematics in the course had a positive impact on students' mathematical belief and attitude. These findings imply that the didactical principle of RME can be applied to design university mathematical courses and in general, provide a perspective on how to reform mathematics curriculum at a university level.

Comparative studies on mathematical modeling cognition feature were carried out between 15 excellent high school third-grade science students (excellent students for short) and 15 normal ones (normal students for short) in China by utilizing protocol analysis and expert-novice comparison methods and our conclusions have been drawn as below. 1. In the style, span and method of mathematical modeling problem representation, both excellent and normal students adopted symbolic and methodological representation style. However, excellent students use mechanical representation style more often. Excellent students tend to utilize multiple-representation while normal students tend to utilize simplicity representation. Excellent students incline to make use of circular representation while normal students incline to make use of one-way representation. 2. In mathematical modeling strategy use, excellent students tend to tend to use equilibrium assumption strategy while normal students tend to use accurate assumption strategy. Excellent students tend to use sample analog construction strategy while normal students tend to use real-time generation construction strategy. Excellent students tend to use immediate self-monitoring strategy while normal students tend to use review-monitoring strategy. Excellent students tend to use theoretical deduction and intuitive judgment testing strategy while normal students tend to use data testing strategy. Excellent students tend to use assumption adjustment and modeling adjustment strategy while normal students tend to use model solving adjustment strategy. 3. In the thinking, result and efficiency of mathematical modeling, excellent students give brief oral presentations of mathematical modeling, express themselves more logically, analyze problems deeply and thoroughly, have multiple, quick and flexible thinking and the utilization of mathematical modeling method is shown by inspiring inquiry, more correct results and high thinking efficiency while normal students give complicated protocol material, express themselves illogically, analyze problems superficially and obscurely, have simple, slow and rigid thinking and the utilization of mathematical modeling method is shown by blind inquiry, more fixed and inaccurate thinking and low thinking efficiency.
