The purpose of the study was to integrate Information and Communication Technology(ICT) into elementary mathematics instruction and to help prospective elementary school teachers understand such integration through developing lesson plans and implementing them in classrooms. Specifically, pre-service elementary school teachers in two universities participated in the study for a semester. While taking the course of elementary mathematics teaching methods, the teachers analyzed pre-developed lesson plans, developed lesson plans using ICT in mathematics for grades 5 and 6, and implemented them. This paper includes how the teachers conceive integration of ICT to mathematics teaching and what are the implications of such integration.

본고에서는 영재교육에서 실제 학습자료의 부족과 이산수학의 중요성이 부각되고 있는 최근의 동향을 감안하여, 초등학교 영재교육에 적용 가능한 이산수학 프로그램을 개발하고자 한다. 우선 프로그램의 개발에 선행하여 관련 이론에 대한 고찰을 하였으며 제 7차 초등학교 수학과 교육과정의 이산수학 관련 내용을 분석하석 교육과정의 내용을 심화 ${\cdot}$ 발전할 수 있는 방안에 초점을 두었다. 특히 이산수학과 관련된 기존의 수학학습 프로그램들은 대부분 순수 수학적 이론을 제시하고 그에 따른 문제를 풀어보는 형식으로 구성되어 있는데, 본고에서는 이산수학의 이론을 중심으로, 문제해결에서 알고리즘적으로 사고하는 능력을 키울 수 있도록 하는 것에 초점을 두어 프로그램을 개발하고자 한다. 즉, 프로그램 자체가 하나의 수학적 원리를 탐구해 가는 과정이 되는 것이다. 또한 이산수학이 수학적 문제해결 학습과 연관됨에 착안하여 프로그램은 Polya의 문제해결학습을 바탕으로 구성하고자 한다.

사회가 변화함에 따라 수학교육과정도 변화를 거듭하고 있으며, 이러한 변화에 잘 대처하기 위해서 교사는 수학교육의 방향에 대한 깊이 있는 성찰과 함께 수학, 교육학, 심리학 등 수학교육과 관련된 학문에 대한 이해가 필요하다. 이러한 교사에 대한 시대적인 요구에 능동적으로 대처하는 방안으로 Wittmann(1984)은 수학교과의 특성상 변하지 않는 요소들을 교수단위(Teaching Units)라 하고, 수학교육을 통합시키는 개념으로 교수단위이론으로 제시하였다. 교수단위는 수학에서 가르쳐야 할 내용들을 목적, 자료, 활동, 배경 등의 4요소에 따라 작은 단위로 조직화한 것으로, 이를 통해 수학연구자나 교사는 가르쳐야 할 내용에 대한 구조적인 이해와 체계적인 조직화를 도모할 수 있게 되어 나아가 사회의 변화에 대응할 수 있게 된다. 본 연구에서는 2007년 개정 수학과 교육과정 도형영역의 교수단위를 학년별로 추출하고, 추출된 교수단위의 특징과 제목을 분석하였다. 이를 통해 교수단위가 수학교육과정연구에 어떻게 활용될 수 있는지 그 방안을 모색해 보았다. 도형영역의 교수단위(TU)는 특징과 제목에 따라 '개념알기형', '개념적용형', '관계알기형'의 세 유형으로 분류할 수 있다. 현재의 도형영역 교육과정은 대체로 개념알기형, 개념적용형, 관계알기형의 순으로 구성되어 있으며, 개념적용형이 개념알기형보다 조금 더 많다. 이는 도형영역 교육과정이 학습한 개념을 다양한 방법을 통해 여러 활동에 적용시켜 봄으로써 도형의 개념을 좀 더 명확하게 알게 되는 초등학생의 발달단계를 고려하여 구성되었음을 알 수 있다. 이러한 교수단위(TU)는 수업자가 도형학습주제에 맞게 수업을 재구성하거나 학생들의 수준에 맞는 수준별 맞춤자료를 제작할 때 유용하게 활용될 수 있으며, 더 나아가 수학연구자들이 새로운 교육과정을 수립하고자 할 때 기초자료로 활용될 수도 있을 것이다. 교수단위는 고정불변의 것이 아니고 계속 보완되고 진화될 수 있는 모델이다. 따라서 앞으로도 많은 수학연구자나 현장교사의 참여로 교수단위가 보다 더 체계적이고 조직적으로 연구되어야 한다. 또한 추출된 교수단위를 교사나 학생들이 보다 편리하게 활용할 수 있도록 컴퓨터용 소프트웨어로 개발하려는 후속 연구가 필요하다.

The mathematical processes are strongly emphasized in 2009 revised national curriculum for mathematics and are expected to be complemented and extended in 2015 revised one. This study aims to investigate how much the processes are being implemented in mathematics classroom and select some elements which need complementation. To do this, we selected the mathematical practices of CCSSM as a reference, because it plays the corresponding role in the United States to the mathematical processes in Korea. We recognized common elements and different elements between the two and analyzed. Considering those, we searched the possibility of newer mathematical process and analyzed the 4th grade mathematics textbooks in relation to questions for mathematical practices. We provided the results of analyses and several suggestions for revising mathematics curriculum and textbooks.

This study is to explore the directions for developing the lesson assessment of the math textbook in elementary school level, which is to embody the recent trends of math assessment and the emphases about assessment given in the revised 2009 math curriculum. To this end, we examined the recent trends of math assessment and the assessment framework of RME (Realistic Math Education) as the theoretical backgrounds. Also we analytically looked at the math-assessment emphases given in the revised 2009 math curriculum, and tried to establish the directions for developing the lesson assessment of the math textbook on the basis of the preceding studies. In addition to, we gave the math items in line with the established directions about lesson assessment. Finally we suggested the issues in relation with the math assessment in the elementary school level.

In this study, we analyzed whether 2015 revised elementary school mathematics curriculum 's standards statements reflect the direction of 2015 revised curriculum. For the objectivity of analysis, 128 achievement standards statements were analyzed based on content - centered statements, activity - centered statements, and performance - centered statements by Seo Young - jin 's (2013). As a result of the analysis, it can be seen that the 2015 revision elementary mathematics curriculum achievement standards statements do not contain enough information to expand the mathematical competence of students. To complement this, the achievement standards statements should include more elements than 'content + function', and other criteria should be developed to clearly communicate the meaning of the achievement standards statements. And it is necessary to supplement the expression of 'function' in the achievement standards in order to improve the expression of the elementary school mathematics curriculum achievement standards statements.

This study is on a supplementary textbook, a mathematics activity book which is first introduced in the fifth curriculum. There was three revision of mathematics activity book with the change of curriculum. On this study, the aim of introducing mathematics activity book, the direction of development, the organization system and the relation with curriculum were analyzed systematically on the basis of literature consideration.

It is the 6th curriculum that first officially mentioned the use of calculators in elementary mathematics education in Korea. Since then, the curriculum has been more widely used than in the beginning. However, in actual textbooks, it is still not enough to see the utilization situation, and guidance in this textbook is very scarce. In particular, there is no relevant study that meets the standards of achievement of the curriculum. The purpose of this study is to investigate the contents of the research on the use of the calculator in the course of the curriculum change after the 6th curriculum, and to present the complex calculation, mathematical concept, mathematical principles and rules, mathematical problem solving. In addition, the course is presented in the textbooks that are appropriate for the achievement criteria and the application process for each topic.

Problem solving has been consistently emphasized in national mathematics curricula, whereas the foci of such an emphasis have been changed. Given this background, this study traced down major changes in emphasizing problem solving from the first national mathematics curriculum to the most recent 2015 curriculum. In particular, both the 2009 and the 2015 revised curricula were analyzed in detail to figure out the latest emphasis and trends. This paper then investigated whether a series of mathematics textbooks were aligned to the emphases of recent curricula. It finally discussed some issues that we need to reconsider with regards to problems, problem solving strategies, and the process of problem solving. As such, this study is expected to provide textbook developers with detailed implications on how to employ problem solving in new series of textbooks.

The seventh curriculum of mathematics which value much of the learners' participative activities became conspicuous by introducing a new system of ‘activities’ to the textbook in particular, Then I categorized and analyzed the ‘activities’ proposed in actual textbooks in the context of specific operative activities. The objective of this study is for understanding the features and trends of the activities proposed in textbooks.
