영화 <코러스>에서 아이들이 학교에서 쫓겨나는 선생님을 위해 종이비행기에 편지를 써서 창밖으로 날리는 장면은 관객들에게 많은 감동을 주었다. 언제부터인지 알 수는 없지만 종이비행기는 사람들의 희망을 담아 하늘로 전달하는 메신저의 역할을 하고 있다. 그래서 종종 꿈이 실현되기를 바라는 마음에서 종이비행기를 날리는 행사가 진행되기도 한다. 하지만 종이접기가 종이비행기처럼 상징적 의미가 아니라 실제로 세상의 많은 것을 바꿔놓고 있다. 그렇다면 종이접기가 어떻게 세상을 바꿔 놓고 있을까?

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.

다각형에서 가장 기본이 되는 삼각형과 사각형의 종이를 접을 때 마다 다양한 규칙성들이 발견될 수 있다. 따라서 본 연구에서는 이런 종이접기를 통한 패턴 탐구를 통해 문제를 형식화거나 일반화 하는 능력과 수학적으로 사고하는 능력 즉, 귀납적 추론력을 길러주고자 함에 목적을 두고 있다.

In general, we do fold paper and unfold, it remain paper traces. We can be obtained by using rectangular paper, a mathematical fact and the program had a combination. Depending on the direction of the rectangle, folding paper in the form of variety shows valley and ridge signs of the appearance of this paper. By using (0,1)-code and (0,1)-matrix, we study four kinds of research. Therefore, traces of this view upside down rectangle folding paper how to fold inductive reasoning ability of the code and explore the relationship of traces. Finally, the mathematical content and program development can practice in the field.

In this paper we study new proofs and generalization of Haga theorem in paper folding. We analyze developed new proofs of Haga theorem, compare new proofs with existing proof, and describe some difference of these proofs. We generalize Haga second theorem, and suggest simple proof of generalized Haga second theorem.

This study is on the teaching method for the students who belong to the same school (one, the gifted class, passed gifted education of Science High school ), 1-1, face-to-face learning (two, good students in regular classroom) with a teacher, paired learning teams (4 people, gifted classes), and group lessons (20 people, gifted classes) and using the justification analysis framework tool(PIRSO) of Kim(2010) analyzes the justification element of the students in the group classes regular polygons paper was to explore ways to improve the justification of the folding maps activities. As a result, the width of the largest polygon difficulty level appropriate to the class for gifted elementary school classes but the individual learning style of the 1-1 face-to-face with a teacher or discussion with colleagues and cooperative approach is justified, rather than the material of the study of origami activities it turned out to be more effective in improving the level of justification. Unlike the individual learning activities, the exploration for class is the need to strain in parallel to the student is selected as needed, rather than serial manner was confirmed that it is necessary to clearly present problems even from the beginning. Development of teaching through the implications obtained from this method of reconstruction activities and proposed improvement measures for questioning.

It ill give much interest both to the teacher and student that paper crane makes interesting mathematical investment possible. It is really possible for the middle school students to invest mathematical activity such as the things about triangle and square, resemblance, Pythagorean theorem. I reserched how this mathematical investment possible through folding and unfolding paper crane and analyzed the mathematical meaning.

By learning math, constructing math problems helps us to improve analytical thinking ability and have a positive attitude and competency towards math leaning. Especially, gifted students should create math problems under certain circumstances beyond the level of solving given math problems. In this study, I examined the math problems made by the gifted students after the process of raising questions and discussing them for themselves by doing origami. I intended to get suggestions by analyzing of problem posing strategy and method facilitating the thinking of mathematics gifted students in an origami program.
