The purposes of this study are, by referring to various previous studies on problem posing, to re-construct problem posing steps and a variety of problem posing learning materials with a problem posing teaching-learning model, which are practically useful in math class; then, by applying them to 4-Ga step math teaming, to examine whether this problem posing teaching-learning model has positive effects on the students' problem solving ability and mathematical attitude. The experimental process consisted of the newly designed problem posing teaching-learning curriculum taught to the experimental group, and a general teaching-learning curriculum taught to the comparative group. The study results of this experiment are as follows: First, compared to the comparative group, the experimental group in which the teaching-teaming activity with problem posing was taught showed a significant improvement in problem solving ability. Second, the experimental group in which the teaching-learning activity with problem posing was taught showed a positive change in mathematical attitude.

2000년 1월 28일에 영재교육진흥법이 제정 ${\cdot}$ 공포되었고, 2002년 4월 18일에 영재교육진흥법시행령이 공포됨에 따라 본격적으로 공교육 차원의 영재교육이 실시되고 있다. 그에 따라 영재교육의 목적을 이룰 수 있는 적절하고 다양한 교수-학습 자료의 개발이 시급한 쟁점으로 부각되었고, 비로소 2002년 6월 15개 시${\cdot}$도 교육청이 한국교육개발원에 위탁해 영재학급과 영재교육원에 투입할 학년별 50차시 분의 초등학교 4${\sim}$6학년 영재 심화 교수-학습 자료를 개발하게 되었다. 하지만 영재교육의 내실을 기하고 활성화를 위해서는 좀 더 다양한 교수-학습자료가 지속적으로 개발되어야 하며 많은 시도가 있어야 한다. 따라서 본 연구에서는 영재학급용으로 개발된 심화 교수-학습 자료에 제시되지 않은 내용을 중심으로 영재학급에 활용할 수 있는 초등학교 5${\sim}$6학년 수학 영재교육을 위한 학습자료를 개발하고자 한다.

국민형 pc의 보급, 학습자의 자기 주도적 학습능력을 향상을 위한 제7차 교육과정의 실현이 바로 앞에 다가오고 있다. 이러한 시대적 변화 속에서 초등수학교육도 수학적 사고력과, 창의력과 문제 해결력 향상을 위해 학습자의 직접적인 경험을 요구하고 있다. 여기에 수학과 교수-학습에서 컴퓨터 활용에 초점을 둔 방향의 전환이 필요하다. 현재 프로그램 중에서는 많은 사용자를 확보하고 접관이 용이한 엑셀프로그램을 동하여 수와 연산, 도형, 측정, 관계영역에서 활용 방안을 제시하고자 한다.

새로운 세기의 수학 교육은 직관과 조작 활동에 바탕을 둔 경험에서 수학적 형식, 관계, 개념, 원리 및 법칙 등을 이해하도록 지도되어야 한다. 즉 학생들의 내면 세계에서 적절한 경험을 통하여 시각적 ${\cdot}$ 직관적으로 수학적 개념을 재구성할 수 있도록 상황과 대상을 제공해야 한다. 이를 위하여 컴퓨터 응용 프로그램을 활용한 자기주도적 수학 개념 형성에 적합한 교수 ${\cdot}$ 학습 모델을 구안하여 보았다. 이는 수학의 필요성과 실용성 인식 및 자기주도적 문제해결력 향상을 위한 상호작용적 매체의 활용이 요구된다. 본 연구는 구성주의적 수학 교수 ${\cdot}$ 학습 이론을 근간으로 대수 ${\cdot}$ 해석 ${\cdot}$ 기하 및 스프레트시트의 상호 연계를 통하여 수학 지식을 재구성할 수 있도록 학습수행지를 제작하여 교사와 학생의 다원적 상호 학습 기회를 제공하는 데 주안점을 두고자 한다.

As the necessity of the special education for the gifted to develop their talents and national power is gradually recognized, many kinds of teaching-learning materials have been developed. However, the development tendency of the materials is not systematically studied because their database is not sufficiently constructed nor most of them are made public. In this research, we would like to provide the reference data to improve the quality of developed materials and reduce the deviation among the classified fields when we will develop the teaching-learning materials by collecting the already developed materials and analyse their development tendency by classifying them according to the contents.

This study is based on the recognition that the school mathematics education should reinforce the heuristic and constructional aspects related with discoveries of mathematical rules and understanding of mathematical concepts from real world situations as well as the deductive and formal aspects emphasizing on mathematical contents precisely. The 11th grade students of one class from a city high school with average were chosen. They were given time to learn various functions of Excel in regular classes of "Information Society and Computer" subject. They don't have difficulty using cells, mathematical functions and statistical functions in spreadsheet. Experiment was performed for six weeks and there were two hours of classes in a week. Considering the results of this research, teaching materials using spreadsheets play an important role in helping students to experience probabilistic and statistical reasoning and construct mathematical thinking. This implies that teaching materials using spreadsheet provide students with an opportunity to interact with probabilistic and statistical situations by adopting engineering which can encourage students to observe and experience various aspects of real world in authentic situations.

This study is to design Flipped Learning classrooms of learner-centered education on the pre-service math teachers education. The study aims to explore the feasibility of teaching and learning method. To achieve the objectives of the study was to explore the teaching and learning model. Flipped learing classroom design includes a main step of a typical process of teaching system. And we designed the model based on the ADDIE Model. This model contains the design steps and the Flipped learning component of the teaching and learning design model. Designed classroom presented in three steps that are before classroom, during classroom and after classroom.

The purpose of this study is to examine a preservice elementary mathematics teacher's beliefs and stated-actions in which she planned and implemented mathematical activities in a field experience within a mathematics methods course. Results show that the preservice teacher seemed to be dealing with conflicts and trying to resolve them in order to make sense to herself. Results also suggest that the preservice teacher's beliefs about how children learn seem to get confirmed through the field experiences so that she was able to articulate, which influence her experience of focusing on an individual child. This, in turn, induces her to elaborate her beliefs. These processes would explain her beliefs and actions as a sensible system.
