본 연구는 문제해결력을 증진시키기 위한 방안으로 상황을 제시한 후 W(상황표현하기)-Q(문제 만들기)-A(답하기)에 의한 단계별 활동을 하여 그 효과성을 알아보았다. 이 방법을 2학년에게 한 학기동안 20차시를 적용한 결과 문제해결력은 향상된 것으로 나타났고, 태도에서는 융통성은 향상되었고 나머지 영역은 유의미한 차이는 없었지만 전반적으로 평균이 높아진 것을 확인할 수 있었다. 따라서 WQA 문제만들기 활동은 아동의 문제해결력을 증진시키고 태도를 개선하는 좋은 방법임을 알 수 있었다.

The purpose of this study is to help to improve the method of math teaching by analysing how learner-centered teaching method offsets mathematical creativity and mathematical disposition. For this purpose, research questions are established as follows; (1) Mathematical creativity between open-ended learning activity approach(OLAA) and general classroom-based instruction(GCI) shows any difference? (2) Mathematical disposition between OLAA and GCI shows any difference? The results obtained through this study were as follows: (1) There was significant difference between OLAA group and CCI group in mathematical creativity. This means that open-ended learning activity approach was generally more effective in improving mathematical creativity than general classroom-based instruction. (2) There was no significant difference between OLAA group and GCI group in mathematical disposition. But the average scores of mathematical disposition except mathematical confidence improved a little. So we can say that open-ended learning activity approach brought an positive influence on students' mathematical disposition. The results obtained in this study suggest that the OLAA can be used to cultivate the children's mathematical creativity and disposition. Therefore, I suggest that teachers should use the OLAA to improve the children's mathematical creativity and disposition.

The purpose of this paper is to contribute to the dialogue about the notion of advanced mathematical thinking by offering an alternative characterization for this idea, namely advancing mathematical activity. We use the term advancing (versus advanced) because we emphasize the progression and evolution of students' reasoning in relation to their previous activity. We also use the term activity, rather than thinking. This shift in language reflects our characterization of progression in mathematical thinking as acts of participation in a variety of different socially or culturally situated mathematical practices. We emphasize for these practices the changing nature of student' mathematical activity and frame the process of progression in terms of multiple layers of horizontal and vertical mathematizing.

This study's aim was to analyze the effect of a project activity based on role play on 5-year-olds' mathematical ability. The participants of this study were 56 5-year-olds from two educational institutions for young children located in two metropolitan cities in Korea. The experimental group (n=28) participated in a project activity based on role play, while the comparative group (n=28) did not. The "Mart Play" project activity based on role play was developed emergently by the children and teachers of the experimental group. The children's mathematical ability was measured before and after the experiment. The data were analyzed using t-test and ANCOVA. As a result, the project activity based on role play had an effect on the improvement of 5-year-olds' mathematical ability generally, but not on their measurement ability.

The purpose of this study is to investigate elementary students' communication in process of applying mathematical modeling. For this study, 22 fifth graders in an elementary school were observed by applying mathematical modeling process (presentation of problem ${\rightarrow}$ model inducement activity ${\rightarrow}$ model exploration activity ${\rightarrow}$ model application activity). And the level of their communication with their activity sheets and outputs, observation records and interviews were also analyzed. Additionally, by analyzing the activity cases of and , this study researched that what is a positive influence on students' communication skills. Whereas showed significant advance in the level of communication, who communicated actively on speaking area but not on every areas showed insensible changes. To improve communication abilities, cognitive tension and debate situation are needed. This means, mathematical education should continuously provide students with mathematical communication learning, and a class which contains mathematical communication experiences (such as mathematical modeling) will be needed.

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.

The purpose of this thesis is to analyze the effect on formation of computational abilities and dispositions to the first grade of elementary school students by applying of communicative teaching and learning activity. As a result of analysis, we could get some suggestive points and also we could make sure that computational abilities and dispositions of the first grade students are formed by applying of communicative teaching and learning activity. However, help and control of teacher have to be with it.

This thesis is a research to develop mathematical problems related to every day life, and to apply to mathematical extracurricular activity. The conclusions are as followings; (1) The materials of mathematical extracurricular activity totaling 34 hours' class time were developed and its theaching methods were thought out. (2) Through studying the mathematical problems related to everyday life, we could create a lively atmosphere in the classroom. (3) Through studying the mathematical problems related to everyday life, we could change the learning attitude of students affirmatively and make the students solve the problems for themselves. (4) We could try to build up to the management of mathematical extracurricular activity.

본 연구는 수학적 모델링 활동을 수행할 수 있는 과제 개발과 이를 기반한 수업 설계의 중요성을 생각하여, 수학적 모델링에 대한 예비교사들의 내재된 인식을 바탕으로 그들이 설계한 수학적 모델링 기반 수업의 특징을 파악하는 데 목적이 있다. 그 결과 예비교사들이 개발한 수학적 모델링 과제는 주로 개념 활용 학습을 목적으로, 실생활 맥락의 소재를 활용한 적정량의 정보를 제시한 다소 구조화된 형태로, 이해, 의미, 개념과 연결이 있는 절차적 과정이 필요한 인지적 요구수준으로 개발된 경향을 보였다. 이를 바탕으로 설계한 수업은 대부분이 준비 활동, 모델 도출 활동, 모델 탐험 활동만을 유도한 경향이 있었다. 본 결과를 토대로 예비교사 교육에서의 시사점을 논의하였다.

The purpose of this study is to estimate teachers'conceptions of mathematics through the conception on compositions of mathematical knowledge, the conception on structure of mathematical knowledge, the conception on status of mathematical knowledge, the conception on mathematical activity, and the conception of mathematics learning. This study reached the following conclusions: Most of teachers has more internal viewpoint than external viewpoint on the compositions, structures and status of mathematical knowledge, mathematical activity and mathematics learning.
