산학서(算學書)에서의 분수셈에 대한 고찰
Park, Young-Sik ; Choi, Kil-Nam ;
East Asian mathematical journal , volume 24, issue 5, 2008, Pages 431~464
In this paper, we investigate reduction and four rules of fractional calculation on GuJangSulHae and the other Sanhakseo, and elementary school mathematics education.
수학교사를 위한 괴델정리의 소개 방안

Even though Godel's theorem is remarkable to mathematics teachers, it is not simple to understand the proof in detail. It would be useful for us to understand the basic ideas and the proving process of the proof. In this note, we suggest a proposal for the purpose.
수학과 음악의 상호작용적 관계에 대한 소고
Ma, Doc-Un ; Lee, Byung-Soo ;
East Asian mathematical journal , volume 24, issue 5, 2008, Pages 477~496
In this paper, we consider the relations between mathematics and music, for examples rational numbers with musical scales, irrational numbers with musical scales, the golden ratio with musical compositions, the Fourier analysis with overtones. Our aim in this paper is to enhance the students' mathematical abilities by using musical materials.
어떤 수열의 합에 대한 두 가지 접근 방법
Youn, Suk-Joo ; Han, In-Ki ;
East Asian mathematical journal , volume 24, issue 5, 2008, Pages 497~507
Two proving methods are investigated. One method uses we mathematical induction and the other uses the progression of difference. Two methods are analysed and compared. As a result, we get a generalization of these series.
종이접기를 통한 패던 탐구 활동

East Asian mathematical journal , volume 24, issue 5, 2008, Pages 509~519
In the article, we study on researching activity of the patterns through paper folding. A set of rules and patterns are found in this study based on folding paper of triangle and rectangle.
Morley 정리의 한 증명방법과 그 활용에 대한 연구

In this study, we'll check the proof of Morley's theorem that calculate the sides XY, YZ and ZX of Morley's triangle. We may now consider calculate area of Morley triangle and observation that, for example, in triangle ABC, length or sides XY, YZ and ZX are
, respectively. Therefore, compare with the area of Morley's triangle XYZ and the area of triangle ABC.

One of the education purpose of the section "Figures" in the eighth grade is to develop students' deductive reasoning ability, which is basic and essential for living in a democratic society. However, most or middle school students feel much more difficulty or even frustration in the study of formal arguments for geometric situations than any other mathematical fields. It is owing to the big gap between inductive reasoning in elementary school education and deductive reasoning, which is not intuitive, in middle school education. Also, it is very burden for students to describe geometric statements exactly by using various appropriate symbols. Moreover, Usage of the same symbols for angle and angle measurement or segments and segments measurement makes students more confused. Since geometric relations is mainly determined by the measurements of geometric objects, students should be able to interpret the geometric properties to the algebraic properties, and vice verse. In this paper, we first compare and contrast inductive and deductive reasoning approaches to justify geometric facts and relations in school curricula. Convincing arguments are based on experiment and experience, then are developed from inductive reasoning to deductive proofs. We introduce teaching methods to help students's understanding for deductive reasoning in the textbook by using stepwise visualization materials. It is desirable that an effective proof instruction should be able to provide teaching methods and visual materials suitable for students' intellectual level and their own intuition.
초등학교 5학년 학생의 자연수 혼합계산에서 나타난 오류에 관한 연구

The purpose of this study was to investigate 5th graders' performance for mixed operational problem. For this purpose. two kinds of studies were conducted: a descriptive study by pencil and paper tests(32 problems) and a clinical study by interviews. The conclusions drawn from the results obtained in this study were as follows: First, students were highly scored in pencil and paper tests(M=85.25%). But that score is not up to scratch. Because the problem was composed of simple calculations and if students calculate problems from only let side, they gel 75% right answer, etc. Second, most of students solved mixed operational problems by text-based way, but some students solved flexibly. There are several error types. The main error type is students' following the wrong order of calculations. Some students have obstacles to express their thought with numerical expressions. So they make errors. Third, students solve mixed operational problems with various strategies. For examples, they solve problems by describing calculation procedures, drawing lines to indicate the order of calculations, carrying out two numerical expressions, etc.
