This study analyzed and discussed instruction methods of polyhedrons in elementary mathematics textbook by using the didactic transposition theory. By further segmenting instruction methods, we analyzed the period and order of teaching of polyhedrons, its definitions and presentation methods, and how instruction methods has changed so far. In elementary mathematics textbooks from the 1st to the 2007 revised curriculum, we choose the part where polyhedrons are introduced as the search-target, and analyzed instruction methods in these textbooks by using phenomenological description. The instruction period and order of polyhedrons were systemized when the system of Euclid geometry was introduced, considering the psychological condition of students, and the instruction period and order had been refined according to the curriculum. And methods of definition took into consideration both the academic systems and psychological situations. Also, the subject of learning has changed from textbook and teachers to students. Polyhedrons were connected to real life and students could build up their knowledge by themselves. Constructions were aimed at the understanding of meaning of contents, rather than at itself. Through these analyses, we have some suggestions on the teaching of polyhedrons in the elementary mathematics.

The elementary and middle school curriculum in Korea has been modified periodically to reach today's 7th national curriculum. Although the intent of each new curriculum was to improve education, lack of proper preparation for teachers and students has not made the new curriculums as effective as it could be. Goodlad et al.(1979) suggested that curriculum should encompass all practices including not only knowledge but all the elements of the curriculum and experiences of the student and teachers. The purpose of this paper is to investigate the actual practices of the current curriculum with focus on the use of instructional media in mathematics teaching and learning. A nationwide curriculum survey was carried out with the Goodlad's curriculum inquiry model as the framework. The result shows that elementary and secondary mathematics teachers used textbook manual (for teachers) and practice books most frequently for their class preparation. In addition to these, mathematics teachers also used manipulatives, visual aids, computers, internet, and calculators in a decreasing order. In general, many mathematics teachers did not use much instructional media in their classes and said that there are not enough effective instructional media to use. However, the teachers have positive attitude toward the educational media that they have used. In this study, we analyzed the survey data regarding educational tools, their use and effects to support the development of a new curriculum model in mathematics for a knowledge-based society.

Discrete Mathematics is newly introduced into the 7th Elementary and Secondary School Mathematics Curriculum of Republic of Korea. Every high school can choose Discrete Mathematics as an optional course from year 2002, but mostly from year 2003. According to its characteristics and objectives in the curriculum, we should know how to implement Discrete mathematics. But it is hard to predict whether Discrete Mathematics will be successful or not, since many studies have shown the lack of readiness for the course. In this study, we analyze the Discrete Mathematics text book developed recently in 2002. Then we see how Discrete Mathematics can be implemented. First, we suggest how the contents in the Discrete Mathematics text book are related to the mathematical values. This will clarify instruction and learning methods in Discrete Mathematics classrooms. Secondly, rich and various discrete contents should be taught. Students should appreciate the realistic merits of discrete mathematics. Thirdly, evaluation methods and their examples will be presented based upon the contents of she text. The evaluation that distinguishes individual achievement levels is closely related with implementation of Discrete mathematics in schools. Finally, we point out the weakness of Discrete Mathematics contents in the 7th curriculum to prepare ourselves for the 8th curriculum.

본 연구에서는 우리나라 초등학교 수학과 교육과정 중 도형 영역의 내용 및 성취기준이 어떻게 변화되어 왔는지 분석하였다. 이를 위해 2015 개정 교육과정을 기본으로 한 분석틀을 기초로 시기별 성취기준을 연속형, 소멸형, 추가형으로 분류하여 그 특성을 살펴보았다. 도형 영역에서 연속형 성취기준은 전체의 51%이고, 학년 및 영역의 변동 없이 지속된 성취기준이 많았다. 소멸형 성취기준은 전체의 20.4%이고, 제3차의 수학 현대화의 영향으로 급격하게 도입되었던 학습 내용들이 제4차 교육과정에서 삭제되면서 가장 많이 소멸되었고, 제7차 교육과정 이후에는 단계형 교육과정과 학년군의 도입으로 학습 내용이 통합되거나 중학교로 이동되면서 소멸되었다. 추가형 성취기준은 전체의 28.6%이고, 제7차 교육과정에서 공간 감각 기르기가 도입되면서 성취기준이 가장 많이 추가되었다. 도형 영역에서 추가형 성취기준이 소멸형 성취기준보다 많은 것은 학습 내용 축소라는 교육과정 개정의 큰 흐름에도 불구하고 시대에 맞는 기하 내용을 적극적으로 도입하려고 노력한 결과라고 할 수 있다. 이와 같은 연구의 결과가 향후 교육과정 개발 시 새로운 성취기준의 구성에 있어서 기초자료로 활용되기를 기대한다.

이 논문에서는 제1차 교육과정에 근거한 초등학교 수학과 교과서 1학년의 내용을 분석하였다. 생활 단원 중심 교과서를 표방한 제1차 수학교과서는 생활상에 있어 자연친화적이며 아이들의 놀이에 해당하는 소재들이 많이 등장하고 있으며, 아이들의 수 세기 능력에 관한 연구 결과를 활용하는 등 실증적인 자료를 교사들에게 제공하려고 노력하였으며, 문자나 기호 등의 사용이 상당히 유예되어 있었다. 또한 연습을 강조하여 반복적인 연습 문제 구성을 선호하였다.

본 연구는 통계적 문제해결 과정의 관점에서, 우리나라 초등 수학교과서의 통계 영역 지도 방식을 분석하였다. 그 결과 통계적 문제 해결의 4단계 중에서 자료 분석단계에 대한 집중도가 심한 것으로 드러났고, 문제 설정과 자료 수집, 결과 해석단계의 비중이 매우 저조한 것으로 분석되었다. 이를 토대로 초등 수학교과서의 통계 영역 교과서 개발과 관련된 시사점을 논의하였다.

본 연구에서는 현행 2011 수학과 교육과정에 따라 개발된 수학 교사용 지도서에서 제시하고 있는 수학 수업 모형을 중심으로 현장 교원들의 만족도와 활용 정도, 요구사항을 알아보았다. 현행 수업 모형에 대한 만족도는 약 80% 정도로 높은 것으로 나타났으나, 활용 빈도는 학기 당 또는 단원 당 1회 정도로 낮은 것으로 나타났다. 다른 교과 중에서는 사회와 과학 수업 모형에 대한 만족도가 높은 것으로 나타났으며, 그 이유로 수업에 활용하기 편리하다는 점을 들었다. 수학 수업 모형의 현장 활용도를 높이기 위한 방안으로 수학의 다양한 내용 영역을 고려한 수업 모형 개발, 수준별 차이를 고려한 수업 모형 개발, 직접 교수법 등 교육과정의 교수학습 방법을 고려한 수업 모형 개발이 필요함을 제안하였다.

This study was executed with the intention of guiding ‘open education’ toward a desirable school innovation. The basic two directions of curriculum reconstruction essential for implementing ‘open education’ are one toward intra-subject (within a subject) and inter-subject (among subjects). This study showed an example of intra-subject curriculum reconstruction with a problem solving area included in elementary mathematics curriculum. In the curriculum, diverse strategies to enhance ability to solve problems are included at each grade level. In every elementary math textbook, those strategies are suggested in two chapters called ‘diverse problem solving’, in which problems only dealing with several strategies are introduced. Through this method, students begin to learn problem solving strategies not as something related to mathematical knowledge or contents but only as a skill or method for solving problems. Therefore, problems of ‘diverse problem solving’ chapter should not be dealt with separatedly but while students are learning the mathematical contents connected to those problems. Namely, students must have a chance to solve those problems while learning the contents related to the problem content(subject). By this reasoning, in the name of curriculum reconstruction toward intra-subject, this study showed such case with two ‘diverse problem solving’ chapters of the 4th grade second semester's math textbook.

This paper focuses on the concepts of a value of ratio and a rate in elementary school mathematics. Although the concept of a value of ratio can be distinguished meaningfully from that of a rate by phenomenological analyses, this distinction is impossible at the elementary school level. Two concepts tend to be treated as identical, therefore they need to be classified by the other methods. By analyzing the series of mathematics textbooks from the first curriculum to the present 7th curriculum, this paper investigated how two concepts have been transposed into the products of school mathematics. In addition, we discussed how the difference of two concepts in the changing process of definitions have been presented clearly to the students. As a result, this paper concluded that the difference of two concepts has not been developed clearly for elementary students in general, except the textbook by the 7th curriculum. The definitions of two concepts were described obscurely so that the students may confuse the concept of a value of ratio with that of a rate. The role of a value of ratio needs to be reconsidered when it is applied to set proportional expressions. Therefore, this paper suggests not adhering to the terminology ‘value of ratio’ to present the ratio as a quotient or the rate as a fractional representation in school mathematics.

In this paper we study the process of changes on the arithmetic education curriculum of elementary school in Japan. The arithmetic education curriculum have been developed through experience-centered curriculum, discipline-centered curriculum into humanistic curriculum, and its pedagogical background is based on the theory of J. Dewey, J. Bruner and J. Piaget, respectively.
