이 연구는 디피가 가지는 여러 가지 성질을 확인하고 디피 활동에서 제기될 수 있는 문제와 추측을 탐구하려는 것이다. 디피는 간단한 삘셈 활동이지만 여러 가지 수학적 사고가 일어날 수 있는 장이 된다고 생각한다. 연구자는 디피 활동에서 제기될 수 있는 여러 가지 문제와 추측을 제시하고, 엑셀과 연구자가 직접 개발한 디피 프로그램을 활용하여 관련 문제를 해결하고 추측을 검사하였으며 관련 자료를 제시하였다. 이 연구에서 제시된 탐구 문제와 자료 및 결과는 초등학교의 일반 학생은 물론 영재 학생에게 수학적 사고 활동을 위한 좋은 자료로 역할을 하리라 기대한다.

$Na^+-H^+$ exchanger (NHE) is the main acid extruder in cardiac myocytes. We review the experimental findings of ion-dependency of NHE activity, and the mathematical modeling developed so far. In spite of extensive investigation, many unsolved questions still remain. We consider that the precise description of NHE activity with mathematical models elucidates the roles of NHE in maintaining ionic homeostasis, especially under pathophysiological conditions.

According to the characteristics of elementary school students in favor of playing games, and to their high energy levels and physical growth states, it is fair to say that students can learn mathematics through 'game playing activities.' These activities are considered to intrigue their interest in class and make them feel less stress from the burden of studying mathematics. Mr. Skemp, who had conducted research on 'game activity' with experimental studies relating to elementary mathematics, recommends that math teachers try to give as many activity-oriented classes as possible to students. The method of 'game activity' by Skemp's operation deals with the whole range of mathematical themes. It is believed by other math teachers that this is not a way to substitute free time or just to have fun in class, but an intentionally well-organized way of learning an entire mathematical course during elementary school. In this research, 5th and 6th grade students needing extra classes after school had been exposed to 'ame activity' by Skemp's operation. As a result, we can figure out its influence on their understanding of arithmetic ability, and on the cognitive definition territory in their minds.

본 연구에서는 모델링 과정의 활동을 세 가지 활동-지각적 활동, 인지적 활동, 메타인지적 활동-으로 구분하여 이 활동들의 상호작용으로 모델을 개발하는 과정을 중학교 학생들을 대상으로 사례연구 방법으로 조사하였다. 연구결과 학생들은 자신의 경험에 기반하여 과제상황을 이해하였고, 도구를 조작하는 지각적인 활동을 하면서 상황을 구조화하였다. 또한 지각적 활동에 기반하여 개발한 모델에 대해 사고하고 추론하는 인지적 활동을 재조직하면서 모델을 개발하였다. 아울러 메타인지적 활동을 통해 모델을 수정하고 정교화하여 일반화 가능한 모델을 개발하였다. 본 연구로부터 모델링 활동은 물리적 세계에서의 지각적인 활동과 추상적인 수학 활동을 연결함으로써 추상적인 수학 지식을 학생들이 이해하기 쉽게 지도할 수 있는 방법이라는 시사점을 얻을 수 있었다.

In this increasingly technological world, the creativity development has been highlighted much in many countries. In this paper, two mathematical activities with Chinese characteristics are presented to illustrate how to integrate algorithmic teaching into mathematical activities to develop students' creativity. Case studies show that the learning of algorithm can be transferred into creative learning when students construct their own algorithms in Logo environment rather than being indoctrinated the existing algorithms. Creativity development in different stages of mathematical activities and creativity development in programming are also discussed.

This study assumes alternative character of the operation of mathematical club in middle school. The case that operated the voluntary mathematics club for one year was analyzed and the educational effect was considered. First, the examination instrument for choosing the members of mathematics club was developed and used. And, diverse teaching and learning materials for improving creativity and mathematical ability of the members were used. Second, the difference of learning result between the experiment group and control one who joined the activities of mathematics club was analyzed. Finally, mathematical club activity based on mathematics history appeared to be effective in improving academic achievement and mathematics exploration activity.

The purpose of this study was to examine the effects of cookbook making activities on young children's mathematical concept and writing development. The participants were comprised of 50 five-year-old children from two intact classes from a kindergarten in Gyeonggi province, and they were divided into an experimental and a comparison group. The experimental group participated in cooking activities and produced cookbooks as extension activities whereas the comparison group carried out only cooking activities. The results indicated that the children in the experimental group received statistically higher scores in mathematical concept- and writing-tests, suggesting that cookbook making activities are a useful educational tool for enhancing young children's mathematical concepts and facilitating their writing development.

본 논문에서는 평형저울을 이용하여 정확한 무게를 측정하기 위한 분동설계 과정에서 적용되는 수학적 내용 및 그 표현들에 대해 탐구하였다. 이 일련의 과정에서 일어날 수 있는 수학 장면과 아이디어 탐구, 2진법, 3진법의 2가지 다른 표현에 대한 이해 등을 포함한 구체적인 수학적 사고의 형성과정을 설명하고 분석한다. 이러한 과정을 현장에 적용하여 학습자의 수학적 사고의 발달과 수학적 성향을 개선시키는데 조금의 보탬이 되고자 하는데 그 목적이 있다.
