Emthusiasm about the introduction of computers into mathematics education is widespred. But, the perspectives about the relationship between mathematics education and computer are diverse. The purpose of this study is to examine theoretical background for using computers in mathematics education. In spite of the pedagogical possibilities of computers. only a small minority of mathematics teachers are using computers in mathematics classroom. It is natural to seek this obstacles within theoretical background of the teachers who manage computers, In this study, We discuss the problems in the two sides. First, due to increased computer activity, relationship of mathematics in school with mathematics in society is changing. It is tension between academic mathematics and practical mathematics. School mathematics have to be changed toward stressing practical mathematics. Second problem is the dialectical relationship between the individual and the collective. While maintaining a respect for the individuality of student contributions. We take into account the social dimension of mathematical meaning-making. We discussed theoretical clarification of work collaborative learning. We propose the case study for the roles of computer in collaborative mathematics learning.

이 논문에서는 컴퓨터와 수학교육을 바라보는 두 가지 서로 다른 입장에 대하여 알아보고, 그 중 구성주의적(constructivist) 입장에서 컴퓨터 환경의 설계를 논의한다. 이를 위하여 컴퓨터와 수학교육을 위한 바람직한 기본 원리를 구성주의(constructionism) 시각으로 살펴본다. 나아가 이러한 바람직한 기본 원리를 '함수화'라는 용어를 사용하여 규정하고, 이를 통해 컴퓨터 환경 설계 방법을 모색해 본다. 이 연구를 통하여 우리는 설계 과정에 대한 논의가 부족한 상태로 학교 현장에 도입되는 기존 컴퓨터용 소프트웨어들에 대한 문제점을 인식하고, 새로운 환경의 설계 원칙과 과정에 대해 논의하고, 실제 구현한다. 그 예로 LOGO와 DGS를 새로운 대상의 도입을 통하여 통합하는 방안에 대하여 논의한다. 이 논문에서 구현한 새로운 대상은 LOGO와 DGS의 함수화 명령 체계를 모두 이용하여 만들 수 있고, 동시에 LOGO와 DGS의 함수화 명령 체계으로 변화하고 조작할 수 있는 대상이다.

This study sought to examine preservice teachers' beliefs about their intent to use computers and Internet resources in mathematics classrooms. Also, web-based instruction on topics in elementary school mathematics was used to foster teachers' confidence and competence in using instructional technology, thereby promoting positive attitudes toward use of computers and Internet resources in the mathematics classroom. The results indicated that students who participated in the web-based instructions exhibited a significantly (p < 0.05) better attitude toward using computers and web-based resources in teaching mathematics than did students in the control group.

This study investigated the perception and utilization about computer of beginning secondary mathematics teachers by utilization frequency of computer. To increase utilization frequency of computer in school mathematics, our finding shows that beginning secondary mathematics teachers should have an interest in computer utilization and perceive computers as an important tool for mathematics learning. In addition, they are likely to use more frequently computer under the condition that computers have sufficient class materials and supplement their shortcomings that have derived less usage in math classes. Therefore, future studies have to investigate not only how to develope textbooks and run after-school classes but also how to make creative discretional activities by computer, which makes computers more useful for teacher training. In sum, the results of case studies for computer usability should be released to motivate computer utilization and increase mathematical thinking ability.

In this paper, we present the theory of computers and mathematics education based on the concept of microworlds for mathematics education. We lust look back some previous papers published in the journal of the Korea society of mathematical education series A and else where. Then we present the new view points regarding mircroworlds and mathematics curriculems, microworlds and mathematics teaching and teaming, microworld based problem centered teaming, and microworld based diagnostics and debuggings. We use JavaMAL microworld that is designed to make LOGO and dynamic geometry system in one microworld to give some examples to explain the necessary mathematics educational needs fur designing microworlds for mathematics education. The JavaMAL microworld is a web based microworld that is programmed using JAVA, and the user on use script language, menus, keyboard, and mouse interaction to use the environment.

The COM curriculum provides first a core of mathematics for all students, and then offers opportunities for students to enter different streams of mathematics studies. The flexible curriculum (COM) is certainly welcome as it focuses on a transition from concrete to conceptual mathematics and on sequentially learning the power of mathematical language and symbols from simple to complex. This approach emphasizes the use of computers in mathematics education in the upper secondary grades. In Mathematics A, one unit is developed to computer operation, flow charts and programming, and computation using the computer. In mathematics B, a chapter addresses algorithms and the computer where students learn the functions of computers, as well as programs of various algorithms. Mathematics C allots a chapter for numerical computation in which approximating solutions for equations, numerical integration, mensuration by parts, and approximation of integrals. But, unfortunately, they do not have any plan for the cooperation study.

In this paper, we discuss two representations of a curve. One is a static representation as set of points, the other is a dynamic representation using time parameter. And we suggest needs of designing a computer microword where we can represent a curve both statically and dynamically. We also emphasize the importance of translation activity from a static representation to a dynamic representation. For this purpose, we first consider constructionism and 'computers and mathematics education' as a theoretical backgrounds. We focus the curve of a parabola in this paper since this is common in mathematics curriculum and is related to realistic situation such as throwing ball. And we survey the mathematics curriculum about parabola representation. And we introduce JavaMAL microworld that is integrated microworld between LOGO and DGS. In this microworld, we represent a parabola using a dynamic action, and connect this dynamic parabola action to recursive patterns. Finally, we remake a parabola for a realistic situation using this dynamic representation. And we discuss the educational meaning of dynamic representation and its computer microworld.

Development of new and highly efficient computer technologies are providing schools and homes with faster and multi-functioning computers, and text-oriented education softwares are now being rapidly replaced by multimedia CAI. There are also increasing needs for computer-literate teachers and more effective CAI materials. The goal of this study is to present effective ways to use computers as teaching aids in mathematics classrooms and how computers affect the students' achievement, interest and attitude in mathematics. Theoretical reviews on learning theories of CAI and multimedia were made before designing teaching plans for mathematics classrooms and the plans were applied to classrooms. The result of this study shows that there is a significant difference in achievement between control group and experimental group, and also indicates that CAI increases the students' interest and attitude in mathematics to a certain extent. Although using computers in classrooms are considered to be more effective in teaching than text-oriented lectures, the number of computers in schools is limited and all the students can not take advantage of individualized drill and practice programs or tutorial programs. One way of various solutions to this problem is developing teaching materials for middle or large sized classes and providing teachers with easy-to-carry notebook computers. And also mathematics teachers should be given more chances to train themselves in developing and using CAI materials.

본 논문에서는 구성주의 교육관의 관점에서 컴퓨터와 수학교육의 관계를 바라보는 '컴퓨터와 수학교육'에 대해 다룬다. '컴퓨터와 수학교육'은 그 필요성에 비해 최근까지 원활히 이루어지지 못했다. 그 이유는 먼저 그 구성요소들 사이의 관계가 명확하게 이해되지 못하였고, 이에 따라 구성주의에 대한 명확한 실천적 전략이 부족하였고, 서로 다른 컴퓨터 하드웨어-소프트웨어 환경들이 유기적으로 연결되지 못했기 때문이다. 이에 바람직한 '컴퓨터와 수학교육'을 위해서는 먼저 구성요소들 사이의 관계를 이해하고, 이를 바탕으로 '컴퓨터와 수학교육'의 실천적 설계 전략을 모색하며, 개별적인 소프트웨어 환경을 마이크로월드의 관점에서 통합적으로 연계시켜야 할 필요가 있다. 본 논문에서는 이러한 문제의식을 가지고 '컴퓨터와 수학교육'의 구성요소인 학생, 수학, 컴퓨터를 중심으로 관계된 이론을 고찰하여 각각에 대한 구체적 실천적 전략으로 구성주의. 함수화, 인터넷 상호작용의 원리를 도출한다. 또한 역사적으로 가장 성공적이고 대표적인 '컴퓨터와 수학교육' 환경인 Logo와 동적 기하 환경(DGS)을 이러한 관점으로 분석 고찰하여, Logo를 행동 문자 명령과 대수적 문자조작을 통해 재귀적 패턴의 탐구가 가능한 환경으로 발전시키고, 점들 사이의 기하적 관계를 다루던 DGS를 관계식과 대수기하적 탐구가 가능한 환경으로 설계, 구현한다. 나아가 Logo와 DGS의 이러한 수준 상승이 가지는 수학교육적 의미를 고찰하고, 타일 및 전개도 등의 새로운 대상을 도입하여 통합 마이크로월드를 구현한다. 본 논문에서는 Logo와 DGS, 그리고 통합 환경을 하나의 JavaMAL 인터넷 환경 속에서 통합 설계하고 이를 구현하며 나아가 그 의미를 논의한다.
