본 연구는 로봇을 활용한 수학 융합 인공지능교육 프로그램을 개발하고 적용하여 인공지능 및 수학적 개념에 대한 학생의 이해 특성을 분석하는 것을 목적으로 한다. 이를 위해 초등 인공지능교육 내용 기준을 분석하여 인공지능의 개념 요소를 추출하고, 이를 효과적으로 융합할 수 있는 수학과 성취기준을 파악하였다. 특히 로봇의 움직임을 활용하기에 적합한 각도 단원과 사각형 단원을 선택하여 그 성취기준을 인공지능교육 내용 요소와 융합하기 위해 수업을 재구성함으로써 5회기(총 15차시) 분량의 프로그램을 개발하였다. 이를 초등학교 4학년 1개 학급 22명을 대상으로 5개월에 걸쳐 적용하고 적용시 드러난 학생들의 이해를 인공지능 내용 주제별로 분석한 결과, 로봇을 활용한 수학 융합 인공지능교육 프로그램은 인공지능 원리 및 수학적 개념 이해에 도움이 되는 것으로 나타났다. 또한 로봇의 활용은 실행 과정 및 결과 도출까지 일련의 절차를 시각적으로 확인하도록 함으로써 학생들의 인공지능과 수학적 이해뿐만 아니라 수업 참여도를 제고하는 것으로 확인되었다.

In mathematics education, teaching-learning activity can be divided largely into the understanding the mathematical concepts, derivation of principles and laws acquirement of the mathematical abilities. We utilize various media, teaching tools, audio-visual materials, manufacturing materials for understanding mathematical concepts. But sometimes we cannot define or explain correctly the concepts as well as the derivation of principles and laws by these materials. In order to solve the problem we can use the computer. In this paper, ′the process of the length of curve being equal to the sum of the vectors when intervals get smaller′ and ′the process of calculating volume of spinning curve by using definite integral.′ Using the computers is more visible than other educational instruments like blackboards, O.H.Ps., etc. Also it can help students with solving mathematical problems intuitively. Consequently more effective teaching-learning activity can be done. Usage of computers is the best method for improving the mathematical abilities because computers have functions of the immediate reaction, operation, reference and deduction. One of the important characters of mathematics is accuracy, so we use computers for improving mathematical abilities. This paper is about the program focused on the part of "the application of definite integral", which exists in mathematical curriculum the second and third grade of high school. When this study is used for students as assisting materials, it is expected the following educational effect. 1. Students will have precise concepts because they can understand what they learn intuitively. 2. Students will have positive thought by arousing interests of learning because this program is composed of pictures, animations with effectiveness of sound. 3. It is possible to change the teacher-centered instruction into the student-centered instruction. 4. Students will understand the relation between velocity and distance correctly because they can see the process of getting the length of curve by vector through the monitor. For the purpose of increasing the efficiencies and qualities of mathematics education, we have to seek the various learning-teaching methods. But considering that no computer can replace the teacher′s role, teachers have to use the CIA program carefully.

21세기 지식기반사회에서 창의성은 리더십 및 전문성과 더불어 인재의 핵심가치로 부각되고 있다. 창의성은 영재성의 주요한 요소이며, 영재교육에서 창의성 계발은 프로그램의 핵심이다. 특히 고차원의 사고력과 이해를 요구하는 수학영역에서의 창의성은 사고의 융통성을 잴 수 있는 척도로 창의성 연구의 기초 도구로 쓰인다. 그러나 수학 창의성에 대한 이론적 연구는 많지 않다. 본 논문에서는 Sternberg와 Lubart가 제안한 6가지의 창의성 접근, 즉 신비주의적 접근, 실용주의적 접근, 심리-역등적 접근, 심리-측정적 접근, 인지적 접근, 사회-성격적 접근에 따라 수학 창의성을 분석하였다. 이는 수학 창의성을 여러 측면에서 고찰해봄으로써 수학 창의성 개념과 최근 연구를 이해하는데 도움을 주고자 한다.

To provide guidelines and a basic understanding of static and continuous zone drawing processes, we propose two different mathematical models in terms of the processing conditions and material parameters. Although the models are not finely tuned, because of assumptions made, they are still useful for the analysis of the process and for predicting the processibility.

The authors have reviewed many mathematical thermal mode lings of bipropellant propulsion system in literatures to gather basic data for developing a computer program which analyses the performance of bipropellant propulsion system. In this paper COMS and its propulsion system is briefly introduced for understanding. The set of first order nonlinear differential equations is reviewed and considered as candidate equations for the program development.

Although student-centered teaching practices have been advocated in mathematics education reform, implementing them at the classroom level remains challenging. This exploratory case study examined two unevenly successful student-centered approaches to see how teachers understand and characterize reform, and to articulate issues in implementing reform ideas. The comparison and contrast between the classrooms showed similar classroom social norms but dramatically different mathematical practices. This affords the possibility of exploring the challenges of reform for teachers and other personnel who are attempting to move teaching practices towards the student-centered ideals.

Mathematical thinking is a core element in mathematics education and classroom learning. This paper wish to investigate how primary four (grade 4) students develop their mathematical thinking through working on tasks in multiplication where greatest products of multiplication are required. The tasks include the format of many digit times one digit, 2 digits times 2 digits up to 3 digits times 3 digits. It is found that the process of mathematical thinking of students depends on their own representation in obtaining the product. And the solution is obtained through a pattern/analogy and "pattern plus analogy" process. This specific learning process provides data for understanding structure and mapping in problem solving. The result shows that analogy allows successful extension of solution structure in the tasks.

The purpose of this paper is to try formulating a working definition of connection of informal and formal mathematical knowledge. Many researchers have suggested that informal mathematical knowledge should be connected with school mathematics in the process of learning and teaching it. It is because informal mathematical knowledge might play a important role as a cognitive anchor for understanding school mathematics. To implement the connection of them we need to know what the connection means. In this paper, the connection between informal and formal mathematical knowledge refers to the making of relationship between common attributions involved with the two knowledge. To make it clear, it is discussed that informal knowledge consists of two properties of procedures and conceptions as well as formal mathematical knowledge does. Then, it is possible to make a connection of them. Now it is time to make contribution of our efforts to develop appropriate models to connect informal and formal mathematical knowledge.

This study investigated school mathematics curriculum of England, newly revised in 1998, focused on the 'shape, space, and measures' 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 curriculum tends to deal with the content which can be understood more intuitively, flexibly, and naturally through the experience and aquisition based on the concrete manipulation. Particularly, it emphasizes that mathematics be realistic and useful in solving a diverse problems confronted in everyday life.
