In 1613 the official-scholar LI Zhi-zao (李之藻) of the Ming Dynasty, in collaboration with the Italian Jesuit Matteo RICCI (利瑪竇), compiled the treatise Tongwen Suanzhi (同文算指). This is the first book which transmitted into China in a systematic and comprehensive way the art of written calculation that had been in common practice in Europe since the sixteenth century. This paper tries to see what pedagogical lessons can be gleaned from the book, in particular on the basic operations in arithmetic and related applications in various types of problems which form the content of modern day mathematics in elementary school education.

In accordance with the tendency of Modern Mathematics laying emphasis on Mathematical structure, that is, on axioms, it is necessary for students to be interested in structure of Geometry on Mathematics Education. In fact, it is of importance not only to obtain new ideas but also to forget old ones in the development of Mathematics. Most students do not understand the Mathematical significance of axioms, and do not know what Mathemetical truth is. Now Non-Euclidean Geometry offers opportunity to understand the essence of Mathematics better, and is no less effective than Euclidean Geometry in training student in logical inference. This thesis is a study with regard to what should be taught and how student should be guided at High school Mathematics. Chiefly Hyperbolic Geometry is discussed in connection with Abosolute Geometry. As Non-Euclidean Geometry has not appeared in our curriculum, some experiments are required before putting it into actual curriculum to find out how much students understand and how much pedagogically useful it can be. This is only a. presentation of a tentative plan, which needs to be criticized by many teachers.

A new variety of non-self generalized proximal contraction, called Hardy-Rogers α⁺F-proximal contraction, is shown in this work. Also, with an example, we prove that such contractions satisfying some conditions must have a unique best proximity point. For some particular values of the constants, that we have used to generalize the proximal contraction, we conclude different α⁺F-proximal contraction results of the types Ćirić, Chatterjea, Reich, Kannan, and Banach with proof, that all such type of contractions must have unique best proximity point. We also apply our result to solve a functional equation.

A martingale is a mathematical model for a fair wager and the modern theory of martingales plays a very important and useful role in the study of the stochastic fields. This paper is devoted to investigate a martingale and a non-martingale on the several stochastic integral or differential equations. Specially, we show that whether the stochastic integral equation involving a standard Wiener process with the associated filtration is or not a martingale.

In modern applications of response data analysis, it has been found that there are stimuli which are independent for some com-binations of levels antagonistic for other and synergistic for some other combinations of levels. Obviously the classical models of stimuli re-sponse function fail to portray such inconsistent behaviour of the stim-uli. The classical model also fail to represent response functions of increasingly synergistic stimuli. Thus it has become necessary to build another type of models to represent relations of both synergistic and an-tagonistc for some combination of levels. This paper will propose a new model that can well explain such inconsistent behaviour of two jointly acting stimuli.

mathematics holds a key position among the subject-matters of school education. Nevertheless, beyond Its Instrumental one, humanity-educational value of mathematics for the general public has been under estimated. For the past fifty years, in the our country there has not been enough systematic and profound examination and discussion concerning the goals of mathematics education in order to establish the philosophy of mathematics education. Thus, in this thesis we argue how mathematics education could contribute to the humanity education. For this, we examine how western educational theorists have emphasized the value of mathematics as humanity education and how their theories have been reflected in the goals of the modern mathematics education. First of all, we discuss Platonism as a philosophical basis of the traditional mathematics teaching mainly with Euclid's "Elements" since the ancient Greece and the relationship between mathematics education and humanity education in the light of this traditional thought. Next, we examine the thoughts of Pestalozzi, Harbert, Froebel who provided the theoretical basis for the public education since 19th century, and discuss the value of mathematics teaching in their humanistic educational thoughts. Also we examine the humanistic value of mathematics education in Dewey's educational philosophy, which criticized the traditional western ethics and epistemology, and established instrumen talism. Further, we analyze how such a philosophy of mathematics teaching is reflected mathematics education of 20th century, and confirm that the formation of Dewey's rational intelligence is one of the central aims of mathematics education of late 20th century. Finally, we discuss the ideals of humanistic mathematics education ; develop ment of the rational intelligence via 'doing knowledge'and change of mind via 'looking knowledge'. In this paper identify the humanistic values of mathematics education through the historical examination of the philosophies of mathematics education, and we could find significance as a fundamental study for one of the most important problems which Korean mathematics educational society confronts, that is establishing the philosophy of mathematics education.

인류의 문명은 수학적 관찰과 사고의 결과를 정립하고 삶과 자연에 대한 인식과 인식방법을 깨우쳐가며 시작되었다. 수학은 이집트와 이라크(메소포타미아) 등의 중동 지역의 문명에 논리적 사고를 일깨운 그리스-로마 문명이 합쳐지면서 크게 기하학과 대수학의 흐름을 타고 발전하여 왔다. 수학은 다양한 분야로 분파되기도 하고 다시 합쳐지는 과정을 반복하며 발전을 거듭하면서 결국 현대문명의 기반과 토대를 형성하였다. 서양 문명의 역사는 실로 수학의 역사인 것처럼 인식되기도 한다. 20세기 말, 컴퓨터의 발달과 함께 수학에서도 새로운 분야가 태동하여 큰 발전을 보았는데, 이 분야가 이산수학 또는 조합수학이라는 이름으로 불리는 수학이다. 조합수학은 '21세기의 수학'이라는 별칭을 가질 만큼 활성적인 연구 분야로 자리를 잡아가고 있으며 교육적 차원의 중요성도 부각되고 있다. 본 논문에서는 조합수학의 발생을 엿볼 수 있는 흥미로운 문제들을 훑어보며 조합수학의 유래와 의미를 논하고자 한다.

이 연구에서는 범우 김치영(1916.12.24. ~ 1995. 4.22) 선생이 남긴 에세이 가운데 대표적인 3편을 선정하고, 이들을 한글 자연어 분석 패키지 KoNLP를 사용하여 언어적으로 분석하였다. 범우선생의 문장 가운데 약 80%는 5 이상 30 미만의 어절 수로 이루어졌다. 그의 글은 해를 거듭할수록 보다 명료해졌다. 이것은 한 문장 안에 들어있는 어절의 수에 대한 평균과 표준편차가 줄고 있다는 것으로 확인할 수 있다. 범우선생은 수학의 구조를 강조하였으며, 현대수학의 특징으로 위상화, category 등을 언급하였다. 특히, '수학', '공리', '구조', 'Euclid', '공리계', '집합' 등과 이들 사이의 관계가 범우선생의 화두였음을 알 수 있다.

일차대전 전의 프랑스 수학사는 괄목할 만 하였으나 일차대전 후 프랑스는 독일과 영국에 비하여 완전히 진공 상태였다. 이에 젊은 프랑스 수학자들은 독일로부터 크게 자극을 받아 Bourbaki학파를 생성하고 때마침 사회적으로나 정치적으로 생성된 구조주의(structuralism)와 발맞추어 수학의 구조적 접근을 시도하였다. 우리는 Bourbaki의 생성 과정과 발전 단계를 알아보고 그 구성원들과 그들이 심혈을 기울여 집필한 책들, 그리고 업적에 대하여 조사한 후 Bourbaki학파의 쇠퇴 과정을 살펴 본다.

Modern society demands leaders who are trained with competence to not only approach knowledge but also create new knowledge by comprehensively understanding and applying it, and a leader with character and commitment to share one's ideas with others and be able to accept criticisms. In response to these societal changes, universities are increasingly adopting 'small group discussion-based classes with an attempt to develop and strengthen communication skills through reading, writing and speaking. This paper seeks to introduce a case of a math lecture, where discussion-based class was applied to mathematical education, requiring practical problem-solving through an argumentative thought process.
