The purpose of this research is to explore teachers' role actions in teaching mathematical problem solving and to analyze the influences of the teachers'role actions on their students' activities and beliefs about problem solving. The results obtained in this study suggested that the teachers' role actions brought qualitative differences to students' activities, and students' beliefs about mathematical problem solving were consistent with the perspective held by their teachers. Therefore, teachers should help students build up desirable beliefs about problem solving. They should understand teaching mathematical problem solving and play proper roles in various situations of teaching mathematical problem solving.

I analyzed the effect of problem posing teaching and teacher-centered teaching on mathematical problem-solving ability and creativity in order to know the efffct of problem posing teaching on mathematics study. After we gave problem posing lessons to the 3rd grade middle school students far 28 weeks, the evaluation result of problem solving ability test and creativity test is as fellows. First, problem posing teaching proved to be more effective in developing problem-solving ability than existing teacher-centered teaching. Second, problem posing teaching proved to be more effective than teacher-centered teaching in developing mathematical creativity, especially fluency and flexibility among the subordinate factors of mathematical creativity. Thus, 1 suggest the introduction of problem posing teaching activity for the development of problem-solving ability and mathematical creativity.

In the previous study, six factors which could disturb students' problem solving in an everyday context were identified and discussed. In this study, teaching materials to help students overcome those disturbing factors for successful problem solving in an everyday context were developed and applied to twenty-nine grade 10 students, and the effects of teaching materials were analyzed. According to the analysis of the correlation between the performance in everyday context problem solving and the benefit from the teaching materials, it was found that students who received the help from the teaching materials showed better performance with statistical significance. And students noted that teaching materials were helpful for them to solve the physics problems. Analyzing the overall performance of students in solving the everyday context problem, students in the experimental group showed better performance than the control group and this performance difference was larger among low-score students in school science testing. However, these differences were not statistically significant because the sample size was small. And, based on the analysis of interviews with students, it was also found that some students who showed low performance might not receive help from the teaching materials because the materials were too complex to be read easily, or because the basic concepts needed to solve the problem were not understood. Therefore, the results obtained from the interviews will be used to design more effective teaching for problem solving in an everyday context.

이 연구의 목적은 우리나라의 초등학교 수학과 문제해결 교육은 어떠했는지를 반추해보기 위해 그동안 우리나라 초등학교 문제해결 지도의 역사를 되돌아보고, 초등학교 수학과 교육과정과 교과서 분석을 통해 문제해결이 어떻게 다루어졌는지를 알아보기 위한 것이다. 그 결과 제4차 교육과정부터 2009개정 교육과정 현재까지 문제해결이 계속 강조되어 왔으나, 그에 따른 교과서에서는 교육과정을 제대로 반영하지 못한 경우가 많음을 알 수 있었다. 또한 제6차 교육과정에서 문제해결에 대한 교육이 양적으로 가장 많은 부분을 차지하다가 그 이후 조금씩 약화되고 있으며, 2007, 2009 개정 교육과정에서는 문제해결을 위한 교육으로 전환하려는 움직임이 있음을 알 수 있었다. 문제해결을 통한 지도는 제대로 이뤄지지 못하고 있다.

이 논문은 전미교사협회에서 제시한 수학의 문제 해결에 대한 기준과 문제 해결 교수에 관한 중학교 수학 교사들의 신념에 대하여 연구자가 직접 디자인한 설문을 시험한 연구이다. 이 설문은 타당도가 검증되었으며 신뢰도가 있음이 판명되었다. 이 설문에 응답한 중학교 수학 교사 124명의 설문에 대한 반응을 분석하였다. 여교사와 남교사는 문제 해결 교수에 대하여 유의미하게 다른 신념을 가지고 있음이 밝혀졌다. 교사들의 나이는 문제 해결 교수 전략에 대한 신념에 영향을 미치지 않음이 나타났다.

The purpose of this study was to develop a teaching strategy focused on problem solving process and explore its effects on science creative problem solving ability, science process skills, science academic achievements and scientific attitudes of students after applying it. Teaching strategy focused on problem solving process employed brainstorming and PMI thinking strategies. The participants were the third grade students of both an experimental class(26 students) and a comparative class(25 students) at the S elementary school located in Goyang-City, Kyonggi Province. The developed strategy was applied to the experimental class for 9 periods of 'Separation of mixture' unit. The results of the tests on the science creative problem solving ability, the science process skills, scientific achievement and scientific attitude were statistically higher in the experimental class.

Mathematical Problem solving has had the largest focus in the spread of mathematical topics since 1980. In Korea, most of the articles on problem solving appeared 1980s and 1990s, during which there were special concerns on this issue. And there is general acceptance of the idea that the famous statement "Problem solving must be the focus of school mathematics"(NCTM, 1980, p.1) in Agenda for Action, reflected in the curriculum of Korea. In a historical review focusing on the problem solving in the National Curriculum of Mathematics, we can infer that the primary goal of mathematics instruction should be to have students become competence problem solver. However, the practices of mathematics classroom and the trends of research in mathematical problem solving have oriented to ′teaching about problem solving′ and ′teaching for problem solving′. The issue of teaching via problem solving′ remain unsolved in the community of mathematics education and we need much more attention to this issue.

Mathematical Problem solving has been the focus of a considerable amount of research over past 30 years. But nowadays problem solving is being beginning to be of less interest to mathematics education researchers. Moreover, mathematics teachers have an urgent need to be provided with well-documented informations about "teaching of(expecially, via) problem solving" though following research issues ：ⅰ) the role of the teacher in a problem-centered classroom, ⅱ) what actually takes place in problem-centered classrooms, and iii) groups and whole classes' problem solving rather than individuals. This paper intends to give some informations about practice of teaching mathematical problem solving in elementary school.ry school.

본 연구의 목적은 문제 해결력을 신장시키기 위해 해결 전략과 각 전략별 문제의 유형을 살펴보고, 전략 지도를 위한 구체적인 방안을 모색하는 데 있다. 전략의 지도 계열은 사용하기 쉬운 전략부터 사용하기 어려운 전략의 차례로, 또 전략 습득에 소요되는 시간이 적은 것부터 많은 것의 차례로 지도하는 것이 바람직하다. 또한, 전략의 습득 지도를 위한 문제는 그 전략의 간편함과 우수함을 알 수 있어야 하고 기존의 지식과 기능으로 해결할 수 있어야 하며, 학생들이 흥미를 느낄 수 있는 문제가 제시되어야 할 것이다. 그리고, 전략의 응용 및 심화ㆍ발전시키기 위해서는 동일한 문제를 여러 가지 전략을 이용하여 해결한 후 각 전략의 특성을 분석ㆍ비교해 보는 기회가 필요하며, 좀 더 복잡한 문제 장면으로 확대ㆍ적용해 보는 기회가 필요하다.

This review of literature establishes a contemporary meaning of mathematical problem solving including young children's mathematical problem solving processes/assessments and teaching strategies. The contemporary meaning of mathematical problem solving involves complicated higher thinking processes. Explanations of the mathematical problem solving processes of young children include the four steps suggested by $P{\acute{o}}lya$(1957) : understand the problem, devise a plan, carry out the plan, and review/extend the plan. Assessments of children's mathematical problem solving include both the process and the product of problem solving. Teaching strategies to support children's mathematical problem solving include mathematical problems built upon children's daily activities, interests, and questions and helping children to generate new approaches to solve problems.
