  • In this paper we studied problem solving related with geometric interpretation of algebraic expressions. We analyzed algebraic expressions, related these expressions with geometric interpretation. By using geometric interpretation we could find new approaches to solving mathematical problems. We suggested new problem solving methods related with geometric interpretation of algebraic expressions.

  • Y2K 문제는 정보화의 커다란 걸림돌이다. 본 논문에서는 국내 민간기업을 대상으 로 설문조사를 실시하여 국내기업의 문제해결의 추진단계, 문제 심각성의 인식도, 문제해결 을 위한 공급업체와의 협의, 문제해결 방법, 문제해결을 위한 준비 등 국내기업의 추진현황 을 분석하였다. 실증분석 결과는 문제의 심각성 인식에서 경영층과 사용자부서가 정보처리 부서보다 낮게 나타났으며, 프로젝트 진척도에서는 설문조사 시점을 기준으로 응답한 모든 업체가 작업이 지연되고 있지만, 필요한 예산 및 대책반을 아직 구성하지 못한 업체가 많으 며, 예상 해결시기를 1999년 후반이라고 응답한 업체도 있었다. 끝으로, 문제해결에 가장 큰 장애요인은 인력(30%), 비용(25%), 시간(24%) 순으로 조사 되었다.

  • This paper analyzed contents related to problem solving in the 7th elementary mathematics curriculum in conjunction with main changes in the next curriculum under discussion. This paper then provided detailed analyses of textbooks and workbooks in terms of principal contents, problem solving strategies, content areas, and problem types in order to look closely at how such instructional materials would put the vision of the curriculum into action. It is expected that many issues and suggestions stemming from the analyses will serve basic information to develop next curriculum and its concomitant instructional materials in a way to fostering students' problem solving ability.

  • The purposes of this study were to examine the general tendency of knowledge and problem solving abilities of children to cope with climate change and to find out whether there is a difference in the ability to cope with climate change based on the gender and age of young children. For this purpose, 129 children aged 5 and 6 who are attended in day care center in Seoul and Gyeonggi area were selected. We used 10 questions to measure climate change response knowledge modified environment conservation knowledge checklist and used five problem solving situations to measure climate change response problem solving ability modified safety problem solving ability test item. The collected data were analyzed using mean, standard deviation, two-way ANOVA, and Pearson's correlation coefficient. As a result, 6-year-old children's knowledge of climate change response and ability to solve climate change problems was higher than that of 5-year-olds. There was no gender difference in knowledge of climate change response and ability to solve climate change. The higher the knowledge level of children's response to climate change, the higher their ability to solve climate change response problems. The results of this study confirmed the association between children's knowledge of climate change response and problem solving ability and showed that a more systematic curriculum for improving knowledge and problem solving ability for preventing climate change needs to be provided to children.

  • It can be said that the teaching and learning of mathematical problem solving has been greatly influenced by G. Polya. His heuristics shows down the explicit process of mathematical problem solving in detail. In contrast, Polanyi highlights the implicit dimension of the process. Polanyi's theory can play complementary role with Polya's theory. This study outlined the epistemology of Polanyi and his theory of problem solving. Regarding the knowledge and knowing as a work of the whole mind, Polanyi emphasizes devotion and absorption to the problem at work together with the intelligence and feeling. And the role of teachers are essential in a sense that students can learn implicit knowledge from them. However, our high school students do not seem to take enough time and effort to the problem solving. Nor do they request school teachers' help. According to Polanyi, this attitude can cause a serious problem in teaching and learning of mathematical problem solving.

  • 문제 해결이 수학교육의 한 목표로 강조되고 있음에도 문제 해결 지도에 있어서 여러 가지 문제점이 지적되고 있는 것이 현실이다. 이러한 문제점 중의 하나는 문제 해결에 대한 교사들의 이해와 그 역할에 대한 인식 부족을 들 수 있다. 본 연구는 수학적 문제 해결 지도에서 교사의 역할 행동을 비교 분석하고, 교사의 역할 행동이 아동의 활동과 문제 해결에 대한 신념에 미치는 영향을 분석하는데 있다.

  • In order to improve mathematical problem-solving ability, there has been a need for research on practical application of meta-affect which is found to play an important role in problem-solving procedure. In this study, we analyzed the characteristics of the sociodynamical aspects of the meta-affective factor of the successful problem-solving procedure of small groups in the context of collaboration, which is known that it overcomes difficulties in research methods for meta-affect and activates positive meta-affect, and works effectively in actual problem-solving activities. For this purpose, meta-functional type of meta-affect and transact elements of collaboration were identified as the criterion for analysis. This study grasps the characteristics about sociodynamical function of meta-affect that results in successful problem solving by observing and analyzing the case of the transact structure associated with the meta-functional type of meta-affect appearing in actual episode unit of the collaborative mathematical problem-solving activity of elementary school students. The results of this study suggest that it provides practical implications for the implementation of teaching and learning methods of successful mathematical problem solving in the aspect of affective-sociodynamics.

  • This study examined the effect of the Collaborative Problem-Solving for Character Competence (CoProC) instruction model within the context of secondary science education. The participants of this study were comprised of 143 Korean students, each of whom was in the 10th grade spread across four class cohorts. These cohorts were further divided into an experimental group (comprised of 73 students from two different classes), which received the CoProC program; and a control group (70 students from two other classes), which did not. In order to assess the effect of CoProC instruction model upon participants' character competence, we designed and administered a Character Competence Test for participants. The CoProC instruction model consists of 3 fundamental steps: Preparation, Problem-solving, and Evaluation. Key character competence targeted in the CoProC program include caring, collaboration, communication, responsibility, respect, honesty, self-regulation, and the development of positive self-image. Thus, these same qualities were targeted and analyzed in the Character Competence Test, which was administered before and after the CoProC activities. The results show a significant increase in the experimental group's competency for caring, collaboration, responsibility, respect, and self-regulation when compared to the control group. Based on these results, we have found that CoProC instruction model to be an effective teaching intervention toward cultivating character competence in a secondary science education setting.

  • 수학적 지식과 능력을 활용하여 생활 주변의 여러 가지 문제를 해결하는 능력의 신장이야말로 수학교육의 목표이자, 수학 학습의 근본적인 이유가 된다. 그러나 문제해결 능력이 가장 많이 필요한 문장제 문제해결과, 문제 푸는 방법 찾기 단원을 학생들은 해결하기 어려워한다. 다른 단원보다 명확하게 식을 찾을 수 있는 연산 문제들과 다르고, 책에 제시되어 있는 방법을 쉽게 사용을 하지 못하며. 그 문제의 의미를 이해하지 못한다. 그래서 문제를 푸는데 즐거움을 느끼지 못한다. 이에 본 연구는 문제 푸는 방법 찾기 단원을 중심으로 문제해결 능력 신장을 위한 교수 학습 시스템 설계를 목적으로 학습의 과정별, 특성별, 연계별 학습 내용을 고려하여 학년 통합, 내용 통합하여 재구성하였다. 그리고 교수-학습 모듈, 평가 모듈, 상호작용 모듈로 시스템을 구성하였다. 시공간의 제약을 극복하여 학습자들의 수준에 적합한 개별화 학습을 제공하고, 웹을 이용한 문제 만들기 활동을 통하여 학습에 자신감을 기르고, 또한, 자기주도적 학습 능력을 향상시키는 계기가 될 수 있을 것으로 기대된다.
