The purpose of this study was to analyze mathematical the effects of problem posing activities on students' characteristics toward mathematics to encourage active learning. We will also examine various examples of the characteristics of the problems made by students with different mathematical characteristics. We chose one 6th grade group to conduct this research. From the results of this study, we obtained the following conclusions. First, problem posing activities are effective in improving students' mathematical interest and confidence, value recognition. Second, Students with different mathematical characteristics showed different results in problem posing activities. We confirmed the effectiveness of problem posing activities on students' positive characteristics of mathematics. In this regard, we were able to confirm examples of various problems that students made. In the future, we would like to propose generalization by conducting research on students of various school ages.

The purpose of this study was to analyze mathematical storytelling in Korean elementary mathematics textbooks and propose some applications for better storytelling, Storytelling strategies were introduced for enhancing students' understanding on mathematical concepts and improving students' attitudes toward mathematics. For this study, the researcher analyzed the 2nd grade mathematics textbook that employs storytelling strategies. The results are as follows. First, current storytelling textbook chapter is designed to appreciate students' intellectual autonomy. Second, current storytelling textbook chapter includes the storytelling that helps understand mathematical concepts and exercise mathematical skills. Third, current storytelling textbook chapter is designed for enhancing students' interest and helping students' character education. The researcher suggested the followings. First, a long term field-based research should be continued for more improved mathematical storytelling materials. Second, a digital format storytelling also needs to be developed as an alternative strategy of mathematical storytelling, which reinforces interactions between teller and listeners.

The Self-reported Evaluation tool developed in this study allows the learners to check and evaluate their own learning by determining the details that are self-assessed. Also this tool allows learners to receive feedback on their self - evaluation results. In this study pre - post test was performed to investigate the effect of self - assessment on the learners' tendency of studying math. The result showed that Self-reported evaluation improved self - confidence, self - strategy on learning mathematics, and meta-cognitive ability. Also by conducting a qualitative analysis of the Self-reported evaluation, students practiced the cognitive activities such as summarizing the contents they have learned that day. They also tried to understand and improve the learning habit, attitude, and learning state. Teachers were also able to communicate with students by providing individual questions and feedback through student's individual Self-reported Evaluation.

This paper investigates how Mind map, Concept map, and Vee diagram facilitates learning mathematics. It also analyzes characteristics, structure, how to make a mall, the possible ways of use and its implications in detail for each map and provides how they can be used for learning mathematics. Mind map is one of most effective tools to make man's thinking power stronger and use the given time as the new way of learning mathematics. Concept map provides the various concepts learned by students more visually with a structured format. As a last, Vee diagram began with the question to explore for the given situation as the tool which is effective in doing exploring and making knowledge acquired vivid in students mind.

The 7th national curriculum shifts the fundamental spirit from teachercentered to learner-centered instruction. According to the shift, performance assessment has been emphasized in schools rather than using a variety of standardized tests. However, some researchers and educational policy-makers recently asserted that we need to return to the kind of standardized tests used in the past, giving up performance assessment, for it can actually not be implemented in classroom. This paper is written to refute their assertion. Performance assessment prove one's real worth when it is implemented in learner-centered instruction. Therefore, some assessment methods are discussed which can be used during learner-centered instruction.

제 7차 교육과정을 비롯하여, 많은 연구들에서 ‘수요자를 중심의 교육’, 즉 학습자의 개별적인 인지적 특성, 수학적 흥미, 재능을 고려하는 수학 교육을 위해 다양한 접근 방법이 모색되고 있다. 1980년대 말 이후부터 러시아에서도 이러한 연구들이 활발하게 진행되고 있다. 본 논문에서는 러시아의 중학교(7-9학년) 수학 교육에서 제시하는 다양한 유형(일반 학생들을 위한 제1유형, 제 2유형, 수학 심화 교육과정)의 교육과정들을 살펴보고, 이를 통해 러시아에서는 교육과정 수준에서 어떤 개별적 접근 방법을 시도하고 있는가를 분석하여, 수학교육의 개별적 접근을 위한 기초 연구를 제공할 것이다.

The information represented by graphic is preferred more than by text to the game generation familiar to computer games in the cognitive style. The learning to solve the math problems represented by graphic is significantly effective to improve learner's problem-solving power in math education. In this paper, we proposed a method of graphic representation of mathematical sentences for effective learning of the game generation. The proposed method arranges the unit informations in the logical structure and represent the logical interrelation between the informations by symbols, line segments, or arrows using the graphic elements with good visibility for the game generation to recognize easily and to understand accurately the logical meaning. The proposed method is able to represent accurately the math sentences until the detail level that appears the tense and the voice of the sentences differently from the previous graphic representation method's ability. The proposed method could be used as learning tools and used widely to represent graphically mathematical informations for the instructional scaffolding of an educational game in oder that the game generation could learn effectively.

The purpose of this study was to examine the relationship between teacher's role and interaction patterns in mathematics classrooms. Teacher's role was divided into usual practices with students, usual practices with content and usual practices with students and contents, and interaction patterns were classified into report, inquiry and discussion. The subjects in this study were teachers and students in three fourth- grade classes in T elementary school located in Seoul. After the classes of every math teacher were observed, three teachers who played distinctively unique roles were selected in accordance with the results of the first-semester autonomous supervision, of open class for parents and of the instructional observation. Thus, there was a close relationship between the teacher roles and interaction patterns. And it's concluded that students are able to have a more discussion on each other's ideas in the student-centered classroom, and that teachers should perform active roles in that process. Given the findings of the study, there are some suggestions: First, the teachers appeared to fulfill consistent roles when their videotaped classes, study aids and performance assessment materials were analyzed, and they should play more active roles in mathematics class. Second, they should try to create the kinds of climate that encourages students to come up with ideas in an active manner. Third, earlier studies had focused on student-teacher interaction patterns, but this study found that the roles of the teachers depended on interaction with not only students but study aids and performance assessment materials, and that the interaction patterns hinged on their roles as well. Therefore more profound research efforts should be directed into this issue.

교육평가는 선발의 기능을 할 뿐 아니라 학습자의 학습상태나 오류경향에 대한 진단을 통해 학습자의 학습에 도움을 주어야 한다. 이르한 측면에서 오류분석은 평가가 지녀야 하는 가장 중요한 기능 중 하나라고 할 수 있다. 인터넷의 대중적 보급과 시간적, 공간적, 기술적 효율성은 평가환경에 대한 새로운 가능성을 제시하고 있다. 인터넷 환경에서의 평가문항은 선다형을 기본으로 하게 되는데, 선다형 평가문항을 통해서는 학습자들의 오류를 직접적으로 관출할 수 없다는 한계가 있다. 그러나 선다형 평가문항을 통한 오류분석이 불가능한 것은 아니다. 본 연구의 목적은 선다형 평가문항에서의 오류분석을 위한 구체적인 방법과 절차를 모색하는 것이다.
