This article provides how to implement the use of Realistic Mathematics Education (RME) in a teaching a function at a school to improve students' mathematization for their mathematical thinking using technology, This study was planed to get research results using the mixed methodology with quantitative and qualitative methodologies. 120 middle school students participated in the study to bring us data about their mathematical achievement and disposition. Through the data analysis used ANCOVA, the students with the experiment of the mathematization and technology excelled the other groups of students who were not provided with technology or both of them. In analysis of the questions of the achievement test, the problems for vertical mathematization were presented harder for the students than the other problems for horizontal and applicative mathematization. The technology environment might have helped students manipulate the application of real-life problems easier. This means that teachers can put more careful assignment on vertical mathematization using technology. We also explored that learning and teaching under RME using technology encouraged students to refine and develop their informal functional concept and pursue higher thinking of formalization. The study results in a lot of resources for teachers to use into their teaching mathematics for improving students' mathematical thinking.

In this paper, we study the effect of writing activity as mathematical communication on the students's mathematics achievement, learning attitude, and mathematical tendency. For this purpose, we construct a experimental class and then analyze the students' change in those aspects after applying three-divided-note writing activity and colleague feedback on their works those students are in the experimental class. As a result of the experiment, we find that three-divided-note writing activity and colleague feedback made some significant changes on the students achievement in mathematics, learning attitude, but does not affect on mathematical tendency. We also offer some suggestions for further research. Firstly, the mathematical communication ability must be stressed in mathematics education. For this purpose, we need to develop the teaching and the evaluation method to use not only writing but also reading, speaking, and listening skills so that many teachers can apply this method easily to their classes. Second, we need to fix some realistic problems such as fair evaluation , the numbers of students per class, the numbers of lesson, and too much extra-work, and so on. Thirdly, we suggest to explore some methods for extending three- divided-note writing activity to evaluate mathematical essay and to study educational effects of colleague feedback on mathematics performance assessment.

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.

Whole number concept is an important part of mathematics learning. Elementary school students should understand and master whole number concept. Models can help students learn whole number concepts. Realistic Mathematics Education in Netherlands had investigated and developed three different structural models: line model, group model, combination model. These models are related whole number concepts and structures closely and compatible. The purpose of this study is to investigate models related with whole numbers in 7th elementary textbooks. As a result of analyses, we found out some pattern and several problems. On the foundation of the analyses, we discussed the better ways of using models in teaching whole number and the research issues concerning these.

This study investigated school mathematics curriculum of England, newly revised in 1998, focused on the 'number and algebra' domain among three major domains of the English curriculum. On the basis of its understanding, this domain was compared and analyzed with school mathematics curriculum of Korea. In doing so, this study explored its plans and procedures and established a frame of comparison for the curriculums between the two countries. The structure of the National Curriculum in England is composed of programmes of study and attainment targets. The former sets out what should be taught in mathematics at key stages 1, 2, 3, and 4 and provides the basis for planning schemes of work, and the latter sets out the knowledge, skills, and understanding that pupils of different abilities and matures are expected to have by the end of each key stage. Attainment targets are composed of eight levels and an additional level of increasing difficulty. According to the results of the present study, Korea focuses on the formal and systematic mathematical knowledge on the basis of sound understanding of certain mathematical terms or concepts. On the other hand, England tends to deal with numbers more flexibly and naturally through the aquisition of mental methods, calculator use methods, etc, and emphasizes that mathematics be realistic and useful in solving a diverse number of problems confronted in everyday life.

현재의 최신 교육과정은 창의적인 인재를 육성하는데 중점을 두고 있다. 하지만 학교에서 실제로 진행되고 있는 수학 교육은 창의성과 거리가 먼 주입식 교육으로 진행되어, 수학을 어렵게 여기는 학생들이 늘어나고 있다. 정부는 이러한 상황을 극복하기 위해 '스토리텔링을 활용한 수학 교육'을 제안하였으며, 이에 게임을 활용한 수학 교육이 다방면에서 연구 개발되고 있다. 그러나 현재 대부분의 교육용 기능성게임들은 연역적 체계를 중시하는 현재의 수학 교육을 탈피하지 못하여, 창의성을 기른다는 목표를 이루지 못하고 있다. 이는 기존의 수학 교육용 기능성 게임들이 수학과목에 대한 목표와 수학 교수 학습이론을 깊이 고찰하지 않았기 때문이다. 따라서 본 연구는 기존의 수학교육이 지닌 주입식 교육의 한계를 넘어서기 위해 수학 교수 학습이론인 RME를 기반이론으로 하여 게임 요소를 활용한 수학적 직관 향상을 위한 초등 기하 교육용 게임 콘텐츠를 개발하는 방법론을 제시하고자 한다.

본 연구는 Freudental의 수학관에 근거한 RME가 표방하는 현실 속 풍부한 맥락적 상황들로 이루어진 관점으로 초등학교 4학년 교과서를 중심으로 한국 및 미국(3종) 교과서에서 제시된 문제의 맥락성을 살펴보았다. 이를 위해 맥락성의 요소를 일상성, 다양성, 수학적 잠재성으로 도출하여 맥락문제를 분류하여 분류된 문제를 비교 분석하였다. 그 결과 한국 교과서는 미국 교과서에 비해, 맥락문제가 차지하는 비율 뿐 아니라, 과정별 맥락성이 모두 낮게 나타났다. 또한 각 요소별 성향을 잘 나타내고 있는 문항을 분석, 기술함으로써 추후 교과서 개발 뿐 아니라, 문항 개발에 의미 있는 자료를 제공할 것으로 기대한다.

In this paper, we demonstrate that one can teach conditional probability in a manner consistent with many features of the statistics education reform movement. Presenting a variety of applications of conditional probability to realistic problems, we propose that interactive activities and the use of technology make conditional probability understandable, interactive, and interesting for students at a wide range of levels of mathematical ability. Along with specific examples, we provide guidelines for implementation of the activities in the classroom and instructional cues for promoting curiosity and discussion among students.
