Mathematical modeling activities hold the potential for diverse applications, involving the transformation of real-life situations into mathematical models to facilitate problem-solving. In order to assess the cognitive, affective, and social dimensions of students' engagement in mathematical modeling activities, this study conducted sessions with ten groups of fifth-grade elementary school students. The ensuing processes and outcomes were thoroughly analyzed. As a result, each group effectively applied mathematical concepts and principles in creating mathematical models and gathering essential information to address real-world tasks. This led to notable shifts in interest, enhanced mathematical proficiency, and altered attitudes towards mathematics, all while promoting increased collaboration and communication among group members. Based on these analytical findings, the study offers valuable pedagogical insights and practical guidance for effectively implementing mathematical modeling activities.

The purpose of this paper is to perceive the problems of current geometry education in the middle school mathematics, to develop some learning materials fitted for the mathematising activities based on Freudenthal's learning theories and to analyze the mathematising process followed by teaching-learning activities. For this purpose, we design activity-oriented learning materials for geometry based on Freudenthal's learning theories, and appropriate teaching-learning models are established for the middle school geometry at the 8-NA stage level according to the theory of van Hiele's geometry learning steps. After applied to the practical lessons, the effects of mathematical activities are analyzed.

This study aims to find out the feasibility and effectiveness of mathematical games as a way to provide primary pre-service teachers with doing mathematics. The game had induced the active participation of elementary pre-service teachers. Through transforming the game, the teachers have been able to experience of mathematical problem posing and generating mathematical representation. Based on this, we discuss the role of mathematical games as a method of pre-service teacher education.

증명은 수학에서 기초적이고도 중요한 주제이다. 추측을 만들어내고 자신에게는 물론 타인에게까지 그 추측을 정리로서 확신시키는 활동은 수학활동에서의 핵심이라고 할 수 있다. 그러나 현재의 증명 학습지도에서는 학생들의 수준보다는 높은 증명 발달단계를 제시하고 있다는 보고와 함께 기존의 지도방법의 개선책을 요구하고 있다. 따라서 본고에서는 몇 가지 증명의 발달 단계를 정리해 보고 Balacheff의 증명 4단계를 토대로 하여 증명활동을 점진적인 구성으로 제시한다.

The seventh curriculum of mathematics which value much of the learners' participative activities became conspicuous by introducing a new system of ‘activities’ to the textbook in particular, Then I categorized and analyzed the ‘activities’ proposed in actual textbooks in the context of specific operative activities. The objective of this study is for understanding the features and trends of the activities proposed in textbooks.

It ill give much interest both to the teacher and student that paper crane makes interesting mathematical investment possible. It is really possible for the middle school students to invest mathematical activity such as the things about triangle and square, resemblance, Pythagorean theorem. I reserched how this mathematical investment possible through folding and unfolding paper crane and analyzed the mathematical meaning.

The aim of this study is to find out how the mathematics activities linked to outdoor movement activities affect children's motor abilities. S kindergarten located in Gyeonggido do conducted a fifteen week program for young children aged five years. In this study, young children's motor perfromenace test scale of Ji Sungae(2007) was conducted. Each area consists of a five-point scale. There were a total of thirty-three questions. pre-tests and post-tests were performed for young children's motor performance. t-test was used. As a result of this study, it was found that mathematics activities in connection with outdoor movement activities had a positive effect on the improvement of overall exercise ability, non-movement exercise ability, and mobility exercise ability of young children. Based on the results of this study, it is expected that various programs for young children integrated with outdoor motor activities will be developed and applied to the site.

The purpose of this study is to identify the influences of the reciprocal writing-reflection activities on the mathematical learning of the 2nd grade students by developing a class model using reciprocal writing-reflection activities method as one of the interactive application of manipulative activities, reflective thought and communication activities which are the learning principles of constructivism. We have experimented and investigated to after dividing experimental objects into two group, experimental groups and comparative group, The conclusions of this study are followings. First, reciprocal writing-reflection activities showed significant effects on mathematical achievements of the group with lower achievements in learning. Second, reciprocal writing-reflection activities positively influenced mathematical tendency of the students. Third, the students had positive attitudes in interest, desire and usefulness regarding reciprocal writing-reflection activities. And reciprocal writing- reflection activities are helpful for their reflective thinking and communication activities.

Nam(2008a) suggested that the role of teacher for helping students to learn mathematical structures should be the manifestor of tacit knowledge. But there have been lack of researches on embodying the manifestation of tacit knowledge. This study embodies the manifestation of tacit knowledge by showing that exemplification is one way of manifestation of tacit knowledge in terms of goal, contents, and method. First, the goal of the manifestation of tacit knowledge through exemplification is helping students to learn mathematical structures. Second, the manifestation of tacit knowledge through exemplification intends to teach students mathematical structures in the tacit dimension by perceiving invariance in the midst of change. Third, the manifestation of tacit knowledge through exemplification intends to teach students mathematical structures in the tacit dimension by constructing explicit knowledge creatively, reflection on constructive activity and social interaction. In conclusion, exemplification could be seen one way of embodying the manifestation of tacit knowledge in terms of goal, contents, and method.
