In this study, we tried to make histo-genetic analyses necessary to identify epistemological obstacles on the function concepts. Historical development on the function concept was analysed. From these analyses, we obtain epistemological obstacles as follows: the perception of changes in the surrounding world, mathematical philosophy, number concepts, variable concepts, relationships between independent variables and dependent variables, concepts of definitions.

수학적 플라톤주의자가 해결해야 할 가장 큰 문제는 바로 베나세라프가 제기하고 필드가 재정식화한 인식론적 문제라고 할 수 있다. 최근에 밸러궈는 자신의 독특한 형태의 수학적 플라톤주의인 FBP 즉 "혈기 왕성한 플라톤주의"는 이 인식론적 문제를 해결할 수 있다는 논의를 전개했다. 필자는 이 논문에서 그런 논의가 얼마나 성공적인가를 평가하면서 그의 논변이 지닌 문제점들을 살핀다. 우선 필자는 밸러궈 특유의 수학적 플라톤주의가 인식론적 문제를 해결한다는 논변을 형식적 측면에서 비판적으로 분석한다. 그리고 밸러궈의 논변과 전략에 대해 마녀주의의 사례를 통해 보다 본격적 반론을 전개한다. 마지막으로 밸러궈가 유비 논변에 기초해 자기 입장을 옹호하려는 대응을 무력화시키기 위한 논의를 펼친다.

This study aims to reflect the origin and the meaning of open education and to derive pedagogical principles for open mathematics education. Open education originates from Socrates who was the founder of discovery learning and has been developed by Locke, Rousseau, Froebel, Montessori, Dewey, Piaget, and so on. Thus open education is based on Humanism and Piaget's psychology. The aim of open education consists in developing potentials of children. The characteristics of open education can be summarized as follows: open curriculum, individualized instruction, diverse group organization and various instruction models, rich educational environment, and cooperative interaction based on open human relations. After considering the aims and the characteristics of open education, this study tries to suggest the aims and the directions for open mathematics education according to the philosophy of open education. The aim of open mathematics education is to develop mathematical potentials of children and to foster their mathematical appreciative view. In order to realize the aim, this study suggests five pedagogical principles. Firstly, the mathematical knowledge of children should be integrated by structurizing. Secondly, exploration activities for all kinds of real and concrete situations should be starting points of mathematics learning for the children. Thirdly, open-ended problem approach can facilitate children's diverse ways of thinking. Fourthly, the mathematics educators should emphasize the social interaction through small-group cooperation. Finally, rich educational environment should be provided by offering concrete and diverse material. In order to make open mathematics education effective, some considerations are required in terms of open mathematics curriculum, integrated construction of textbooks, autonomy of teachers and inquiry into children's mathematical capability.

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.

The values and methods of mathematics education which mathematics teachers tried to impart to their students have varied historically according to the situations of each institution. The cases of the mathematics education in Cambridge University and University College, London show that the peculiar meanings or values of mathematics education were transmitted on students and the methods or focus of the teaching were uniquely determined under the influences of university examinations or conditions of students. In specific, the characteristic education of Augustus De Morgan who studied in Cambridge University and then taught in University College, London reveals better the different institutional contexts. In this paper, I suggest mathematics teachers reconsider mathematics learning motivations on their institutional contexts.

We review the mathematics education in Korea just after the 1595 Liberation and the first, second curriculum announced in 1955 and 1963, respectively. The 3rd curriculum announced in 1973 is influenced by “New Mathematics” in America. There were theoretical research about “New Mathematics”, but no experimental research about it in the school. So, there was not much effect of “New Mathematics” in mathematics education. After that we have the 4th, 5th and 6th curriculum which is improved by the result of experience in teaching. The 7th curriculum announced in 1997 emphasized practical mathematics. In this paper, we review the mathematics education and consider some problems in the 7th curriculum. We also consider some problems in mathematics textbook authorization under the 7th curriculum. To solve these problems, we suggest some facts. Especially, we need the philosophy about mathematics education and the enough knowledge about “Mathematics for Mathematics Teachers”.

Traditional mathematics education research is based on mathematics and psychology, but its function is limited. In the end of the 1980's, the social research of mathematics education appeared. The research views are from sociology, anthropology, and cultural psychology, and then it is an exterior research. The social research considers the relations, power, situation, context, etc. This paper analyzes the power relationship in mathematics classroom. Firstly, the power is defined. The meaning of the power is the foundation of this paper. Secondly, the power relationships in mathematics classroom are analyzed. The traditional mathematics classroom and collaborative learning classroom are considered. Thirdly, the paper analyzes the power resources and finds the some important factors that affect the power distribution.

In this perspective paper, we present seven elements of the appropriate educator mindset for teaching in the constructivist elementary mathematics classroom. The elements include supporting students as they construct their own understanding, eliminating deficit view of slow learners, setting new understanding and growth as the learning objective, providing opportunities to co-construct meaning with peers, using student contributions as the source of curricular material, encouraging all students to participate in learning, and providing instruction not bounded by time. In our struggles to provide authentic, inclusive elementary classrooms, we hope that our discussion of the educator mindset can increase discourse on constructivism from philosophy to practice in the community of mathematics education and policy makers.

전기 비트겐슈타인의 『논리-철학 논고』에서 논리철학과 수학철학은 가장 핵심적이고 중요한 주제들에 속한다. 그렇다면 비트겐슈타인은 『논고』에서 논리학과 수학에 관해 어떤 철학적 견해를 보였는가? 가령 그는 프레게와 러셀의 논리주의를 받아들였는가 아니면 거부했는가? 그는 수학과 논리학의 관계를 어떻게 규정했는가? 가령 "수학은 논리학의 한 방법이다."(6.234)와 "논리학의 명제들이 동어반복들 속에서 보여 주는 세계의 논리를 수학은 등식들 속에서 보여 준다."(6.22)를 우리는 어떻게 해석해야 하는가? 그리고 비트겐슈타인은 『논고』에서 동어반복과 등식의 관계를 어떻게 파악했는가? 나는 이 글에서 『논고』를 중심으로 이러한 물음들에 대해 대답하고자 한다.

우리나라 학생들은 수학의 인지적 영역에서는 높은 성취를 보이지만 정의적 영역에서는 현저히 낮은 성취를 나타내고 있다. 본 논문에서는 수학의 정의적 영역 중 수학의 가치 교육 문제에 대하여 폴라니의 인식론을 바탕으로 논하였다. 폴라니의 인식론에서는 개인적 지식과 지식의 암묵적 차원을 강조한다. 그는 수학의 추상성, 일반성을 강조하였고, 수학의 발전은 공리적, 형식적 측면보다는 지적 아름다움과 열정에 의하여 안내된다고 하였다. 이러한 폴라니의 인식론의 관점에서 볼 때, 수학의 유용성, 실용성 등의 언어적 전달이나 표면적인 흥미 유발을 위한 활동은 본질적으로 가치 교육 및 수학 공부의 내재적 동기 부여에 한계가 있다. 수학 공부의 가치는 적절한 수학 문제에로의 몰입과 긴장, 그리고 문제가 해결되면서 따르는 기쁨, 환희를 맛보며 몸으로 체득하면서 배워야 하는 것이다.
