A Statistical Analysis on the Contents on Probability and Statistics in 1-6 Grade Mathematics Textbooks in Korea
Jang, Dae-Heung ;
Communications of Mathematical Education, volume 21, issue 3, 2007, Pages 361~384
In Korea, mathematics education of 1-6 grade students has been taken according to the 7th national mathematics curriculum, which was renovated by the Ministry of Education and Human Resources Development announcement in 1997. The education of probability and statistics has been carried out as a part of this curriculum. We analyze the contents of probability and statistics in 1-6 grade mathematics textbooks and propose the solutions about the problems on the contents of probability and statistics.
A Study on Investigating Various Properties of Triangle's Escribed Circle and Tetrahedron's Escribed Sphere
Kim, Kyeong-Sun ; Han, In-Ki ;
Communications of Mathematical Education, volume 21, issue 3, 2007, Pages 385~406
In this paper we study on various properties of triangle's escribed circle and tetrahedron's escribed sphere. In order to accomplish our study we extract some base problems related with investigating these properties. Using the base problems we are able to prove various properties of triangle's escribed circle, and to systemize these properties. And we succeed in drawing an analogy related with tetrahedron's escribed sphere.
Review on the Extreme Didactic Phenomena in the Mathematical Class

The extreme didactic phenomena that occur by ignoring or overemphasizing the process of personalization/contextualization, depersonalization/decontextualization of mathematical knowledge is always in our teaching practice and in fact, seems to be a kind of phenomena that suppress teachers psychologically or didactically. The study of the problems on error, misconception or obstacles revealed by students has been done continuously, but that of the extreme didactic phenomena revealed by teachers has not. In this study, I will explain four extreme didactic phenomena and help you understand them by giving various examples from several case studies and analyzing them. And also, I will discuss the way to overcome the extreme didactic phenomena in the mathematical class, based on this analysis. This thesis will become a standard of didactic phenomena that are proceeded extremely by having teachers reconsider their own classes and furthemore, will offer the research data for considering better didactic situation.
A Study on middle school students' conceptions of the polygon revealed in activities using a lattice worksheet

A polygon is one of the main subjects of the geometry curriculum that is handled widely from the second-grade elementary school to middle school. In this research, we analyze second-grade middle school students' conceptions of the polygon that are revealed in the process of seeking the definition and the area of it given in a lattice worksheet.
A Study on Application of Euclid's Geometry at Unit of Equation of Figures in High School 1st Grade

Geometry in school mathematics is the field that has the possibility of diverse approach such as Synthetic Geometry and Analytic Geometry. Synthetic Geometry is handled in middle schools and Analytic Geometry in the first year of high schools. Therefore, this research show for the possibility of using Synthetic Geometry in high schools which was learned already in middle schools and the way of integrating both of them concretely. This is expected to help students understand the mathematical meaning of figures a lot.
The Analysis of the Attitudes of Engineering Students to Mathematics and Its Implications
Kim, Byung-Moo ;
Communications of Mathematical Education, volume 21, issue 3, 2007, Pages 467~482
In this paper, we surveyed the attitudes of engineering students in 6 universities in Chungcheong area to mathematics by 5-scale degrees and performed a comparative analysis of the results. The results revealed a number of meaningful points which should be applied to college mathematic education. On the basis of the results of the analysis, we made the following suggestions; 1) It is necessary to pay much attention to the students who have insufficient math ability 2) Special teaching methods are required for Freshman engineering students 3) Practical teaching strategies should be developed for engineering students that are based on the research on their math background 4) We should develop more materials in the area of mathematical concept image 5) More attention should be paid to the relation between math concepts and engineering concepts. Besides the above suggestions, we proposed that more research about students' math background and attitudes should be conducted for more efficient college math education.

It is necessarily required to improve how the curriculum of general mathematics and teachinmethod should be managed at university level due to students' avoidance to mathematics and science, various types of college entrance system and change of environment of education, etc. This paper provides the levelled teaching method to overcome the differences of students in academical sense and suggests effective teaching and learning method for general mathematics along with the appropriate teaching materials for each level of students.
The Operational Approach and Structural Approach to the Mathematical Concepts - Focusing on exponential function and logarithmic function -

Communications of Mathematical Education, volume 21, issue 3, 2007, Pages 499~514
In modern mathematic education, the development of mathematical ability based on the understanding of mathematical concepts has been emphasized in curriculum and teaching methodology. Also, in schools, most math teachers stress the importance of mathematical concepts in doing math well. Thus, in this paper, we outlined the development of mathematical concepts through the literature survey. And then, based on the Sfard's definition of mathematical concepts, which classifies math concepts into the operational approach and structural approach, we analyzed the math concepts of exponential function and logarithmic function units in three highschool math textbooks. As the result, we found that the textbook authors used different approach for the same concepts, and, at the same time, they used both approaches to help develop the students' math concepts.
A Study on Equations of Bisector and Trisectors of Angle
Lee, Sang-Keun ; Lee, Chun-Goo ;
Communications of Mathematical Education, volume 21, issue 3, 2007, Pages 515~525
In this study, we study on equations of bisector and trisectors of angle. We analyze various studies related with bisector and trisectors of angle. As a result we have known that trisectors of angle is able to received by paper folding method. Using some concepts of vector we have described equations of bisector and trisectors of angle.
A Study on the Change of Mathematical Practice

It takes much of times and efforts for mathematical knowledge to be regarded as truth. Mathematical knowledge has been added, and modified, and even proved to be false. Mathematical knowledge consists of mathematical languages, statements, reasonings, questions, metamathematical views. These elements have been changed constantly by investigations and refutations of mathematicians, by modification of proofs considering the refutations, by introduction of new concepts, by additions of questions about new concepts, by efforts to get answers to new questions, by attempts to apply previous studies to the present, constantly. This study introduces the change of mathematical knowledge instituted by filcher, and presents examples of the change.
An Application of R Commander on Probability and Statistics Education in Middle and High School Mathematics

Communications of Mathematical Education, volume 21, issue 3, 2007, Pages 541~557
Jang(2007a, b) described the overall explanation about R statistical package and application on probability and statistics education. With referring the contents of the 7th national mathematics curriculum, we suggest the plan for applications of R Commander on probability and statistics education in middle and high school mathematics.

Traditionally, the university mathematics has consisted of contents without consideration of the students' major and state of students' academic achievement. Even though this kind of policy seems to be good overall, there are some drawbacks because it does not give much consideration to the current system of entrance examinations and change of society. Hence we are required to classify contents of general university mathematics according to particular majors and colleges. Furthermore, we need to adjust the difficulty level of contents according to the appropriate level of academic need and standard.
