This thesis is to see if the classes using problem posing is effective to improve the students' grades in math. So I set up research subjects as follow. 1. Do the classes focused on problem posing have any influence on the students' achievement\ulcorner 2. Do the classes focused on problem posing have any different influence on the students' achievement according to their levels\ulcorner 3. Do the classes focused on problem posing have any different influence on the students' achievement according to the categories in math\ulcorner I close four classes in the first grade of K middle school in Kangnung, Kangwon province for this thesis. First I divided them into two groups. Each group consisted of two classes. One is the experimental group. The other is the comparative group. The experimental group was taken classes using problem posing. The comparative group was taken classes by the traditional teaching method. And then I analyzed the difference of the achievement between two groups. As a result of this research, I came to the conclusion as follow. First, the classes focused on problem posing is more effective than traditional teaching method for the improvement of the students` achievement Second, both the classes using problem posing and the traditional teaching method doesn`t affect to the advanced students. Third, the classes using problem posing is more effective to the intermediate students and lower level students than the traditional teaching method. Especially it is very effective in teaching the students the linear equation.

One of the prerequisites for the improvement of the teaching of mathematics in our country is an improved curriculum-one which takes account of the increasing use of mathematics in science and technology and in other areas of knowledge and at the same time one which reflects recent advances in mathematics itself. In the new curriculum of mathematics, we have found the problems to teach the concept of sets at secondary level. The idea of a set is the most fundamental one in mathematics. So, this thesis contains the studies of the systematic analysis of sets in dealing with the traditional textbook. The scope of the work is limited to the fundamental ideas, and so it merely touches on the topics of the Concpets, Operations, Cardinal Numbers, Application of Logic, one-to-one Correspondence, Probability and so on. It provides only the essentials, definitions, proofs and some example which are already known and understood in their traditional context. It also presents at the appropriate stages the concepts required (illustrated by examples) in a much clearer fashion than classical teaching does. To compete a study of the sets covered in the textbook of each year, greater detail is needed at the appropriate level.

Ten years have passed since Korea began its movement of modernization of mathematics education. In that period, there have been many studies for the movement. But most of the studies were those of curriculum. But the topic of this report reveals that the modernization of mathematics education in Korea depends on the frontiership, the deliberate studies of materials and the improvement of teaching forms in class.

The purpose of this research is to promote the academic achievement motivation and improve problem solving ability in Mathematics. In addition I hope to explore a new teaching method and facilitate students interest in mathmatics. If the teachers utilize an Internet Web Page and exchang information, the interaction activities will allow them to collect and analyse a variety of data. As this teaching method assists students motivation to get the effects of self-regulated learning strategies of students using the internet and their academic achievements and learning attitudes can be explored. The information will be gathered after the students participate in classes which were taught through the Edunet Homepage and the Department of Mathematics Homepage of KongJu National University. The Internet pages focused on the "Function" chapter of the first grade text for students attending middle school. The students were divided into two groups, experimental and comparative. Each group is composed of three levels, high, middle, and low. In the post experimental phase, two tests were administered which measured achievement ability and the learning attitude of the students. The results of the tests were then compared and analyzed. The results were as follows: First, the study demonstrated that self-regulated Learning Starategies towards Academic Achievements and Learning Attitudes were more effective than traditional teaching methods. These methods were significantly effective in the middle level and low level groups. The study demonstrated little to no improvement in the high level groups

본 연구에서는 초등학교 교사들을 대상으로 2007 개정 교육과정 3, 4학년 수학 교과서의 '열린 질문'에 대한 인식과 지도 실태를 설문조사 하였다. 그 결과, 교사들은 열린 질문의 취지에 대해서는 전반적으로 공감하고 있지만 교과서에 제시된 열린 질문과 그 지도상의 실제에 대해서는 교과서 열린 질문 자체, 교실 수업에서의 실행, 교사용 지도서와 교사연수 등에 걸쳐 여러 문제점을 인식하고 있다는 사실이 확인되었다. 본 연구에서는 이러한 조사 결과를 바탕으로 교과서 '열린 질문'의 개선 방향을 제안하였다.

본 연구의 목적은 현행 7차 교육과정에서 강조하고 있는 학습자 중심 수학 수업 방식에 대한 초등학교 교사들의 신념의 구조를 이해하고, 이들 신념과 관련된 요인들이 수업 개선 의지에 어떻게 그리고 얼마나 영향을 미치는지 설명하고 예측함으로써 교사들의 수업의 질 향상에 도움이 되는데 있다. Fishbein과 Ajzen이 개발한 Theory of Planned Behavior 이론은 본 연구에서 교사들의 수업개선 의지, 신념, 태도, 주관적 규범 및 통제요인의 지각에 영향을 미치는 요인들을 체계적으로 조사하는데 개념적 틀을 제공하고 있다. 자료 수집을 위하여 281명의 초등학교 교사들이 본 연구에 참여하였으며 수집된 자료의 분석을 위하여 기술적 통계 분석과 다중선형회귀분석을 적용하였다. 연구 결과에 의하면 초등학교 교사들의 수업 관행의 변화는 우선적으로 수학을 학습자 중심으로 가르칠 때 예상되는 결과들의 가능성에 대한 주관적 판단에 의해 영향을 받는 것으로 보인다. 학습자 중심 수학 학습에 대한 교사 주변인들의 요구 또한 교사들의 수업 개선 의지에 약간의 영향을 끼치는 것으로 나타났다. 그러나 수업에 대한 통제요인 등은 수업 개선 의지를 예측하는데 크게 영향이 없는 것으로 판단된다.

This thesis analyzes the nature of proof in the perspective on the philosophy of mathematics. such as absolutism, quasi-empiricism and social constructivism. And this thesis searches for the improvement of teaching proof in the light of the result of those analyses of the nature of proof. Though the analyses of the nature of proof in the perspective on the philosophy of mathematics, it is revealed that proof is a dynamic reasoning process unifying the way of analytical thought and the way of synthetical thought, and plays remarkably important roles such as justification, discovery and conviction. Hence we should teach proof as a dynamic reasoning process unifying the way of analytic thought and the way of synthetic thought, avoiding the mistake of dealing with proof as a unilaterally synthetic method. At the same time, we should make students have the needs of proof in a natural way by providing them with the contexts of both justification and discovery simultaneously. Finally, we should introduce the aspect of proof that can be represented as conviction, understanding, explanation and communication to school mathematics.

The purpose of this study was to improve academic achievement and mathematics learning attitudes in the formative assessment using descriptive problems as an effective teaching method. In this paper we set the following research questions. First, how would you improve students' academic achievement utilizing descriptive evaluation? Second, how would improve students' mathematics learning attitudes utilizing descriptive evaluation? Third, what was the reaction utilizing the descriptive method to evaluate? The result of this study could be seen as follows. The experimental group than the control group on academic achievement shows a significant improvement. Second, the experimental group compared to the control group in mathematics learning attitude changes could be helpful and appreciated. Third, experimental group than in the control group indicates significance could be seen in the reaction.
