Since the greater part of mathematical concepts have been developed in the direction of “from the concrete and realistic aspects to the abstract level”, children should be secured to learn mathematics genetically with various manipulative materials. The aim of this study is to instigate the active use of geoboards in mathematics classroom. To achieve this arm, we first embodied the several significances on the use of geoboards in mathematics instruction. And we then performed an instruction that children discover and justify the formula related to the area of trapezoid by exploring with geoboards, and analyzed the instructional episode to support our assertion about some secure merit accompanied by using geoboards. From this study, we obtained the conclusion that geoboard activity contains many significances such as children can explore congruence, symmetry, similarity, fundamental properties of figures, and pattern. Futhermore, geoboard activity enable children to transform a figure into other equivalently, develop spatial sense, have basic experiences for coordinate geometry, build a concrete model to explain abstract ideas, and foster the ability of problem solving and mathematical thinking.

Over the years, the benefits of instructional manipulatives in mathematics education have been verified by classroom practice and educational research. The purpose of this paper is to introduce how the instructional material, specifically, geoboard could be used and integrated in elementary mathematics classroom in order to develop student's mathematical concepts and process in terms of the following areas: (1) Number '||'&'||' Operation : counting, fraction '||'&'||' additio $n_traction/multiplication (2) Geometry : geometric concepts (3) Geometry : symmetry '||'&'||' motion (4) Measurement : area '||'&'||' perimeter (5) Probability '||'&'||' Statistics : table '||'&'||' graph (6) Pattern : finding patterns Further, future study will continue to foster how manipulatives will enhance children's mathematics knowledge and influence on their mathematics performance.

수학 도형 영역에서 기하판과 같은 구체적 조작도구를 활용하여 학습하면 추상적인 기하 개념을 이해하는데 효과적이며 학습 흥미도와 문제 해결 능력을 높여줄 수 있다. 현재까지 구체적 조작도구는 고전적인 교실학습 환경에서만 적용하고 있으며 온라인 환경에서는 거의 없었다. 본 연구에서는 수학 도형 영역에서 다각형 주제를 기하판을 활용하여 학습할 수 있는 교육용 소프트웨어를 설계하고 구현하였다. 소프트웨어의 기본 기능은 도형 그리기와 지우기 기능으로 구성되어 있고 학습한 내용의 도형을 맞게 그렸는지 확인할 수 있다. 연구에서 개발된 도구는 델파이 분석으로 도형 영역 학습에 도움을 줄 수 있고 학습 흥미도를 높일 수 있을 것이다.

The purpose of the study was to investigate the effects of the geoboard activities in understanding the Pythagorean Theorem. Five groups of middle school students were involved in the study. The research questions of the study were followings: 1)What are the differences in understanding and attitudes among students those who revealed the various levels of achievement when geoboards were introduced in learning the Pythagorean Theorem. 2)What was the effect of the geoboard activity in introducing the Pythagorean Theorem and solving relevant problems? 3)What would be the impression of geoboard activity for those who already knew the Pythagorean Theorem? 4)What would be the effects of interaction in geoboard activities? 5)What was the effect of the geoboard activity in recovering the Pythagorean Theorem, and applying the theorem. The result of the study revealed the positive effects of geoboard activities throughout the research questions although there were differences among various levels of students and groups.
