대부분의 수학 수업이 알고리즘을 숙달시키고, 기계적으로 익힌 절차에 의해 정답을 맞추는 것에 중점을 두어 왔기 때문에, 학생들은 수학은 딱딱하고 어렵고 재미없는 과목이라는 인식을 많이 하고 있다. 그러나, 수학 수업에서 수학 교구의 조작 활동을 한다면 수학적인 흥미를 유발할 수 있을 뿐만 아니라 추상과 형식적인 수학으로의 발달을 돕고 학생들이 활동적으로 수업에 참여할 수 있게 된다. 이러한 맥락에서 제 7차 교육과정의 '도형'영역에서는 조작 활동을 통한 자기 학습능력 개발에 중점을 두고 주위의 실제 생활에서 볼 수 있는 사물을 관찰하여 그 성질을 추상해 낼 수 있도록 구체적인 교구를 이용하는 조작 활동을 강조하고 있다. 본 연구에서는 이러한 관점에서 정규 수학 수업이 아닌 일선학교의 클럽 활동 시간을 이용하여 학생들이 수학 교구를 충분히 조작하고 활용할 시간을 제공하며, 학생들이 수학 교구의 조작 활동을 통한 클럽활동이 학생들의 수학적 성향 및 능력 수준에 따른 도형 학습능력에 어떠한 변화를 미치는 지를 사례를 중심으로 논의하고자 한다.

초등학교에서 제 7차교육과정은 2002학년도부터 모든 학년에서 운용이 시작된다. 우리는 새로운 교육과정의 기본 방향을 ‘학습자 중심교육과정’이라 하고, 이에 대한 실천방안으로 초등수학교육에서는 ‘활동중심’ 교육과정의 전개를 특징으로 하고 있다. 특히 활동 중심교육에서 가장 중요한 것은 활동의 대상이 되는 교구의 활용이라 할 수 있다. 이러한 교구들 중에서 가장 일반적인 것은 조작교구이므로 이러한 조작교구의 종류와 특징, 성질을 이해하고 활용하는 것은 매우 중요하다. 그러나 실제 학교현장에서는 이러한 자료 활용에 대한 준비와 연구 미흡으로 실천하는데 어려움을 겪고 있는 것이 현실이다. 이에 본 연구에서는 보다 효과적으로 조작교구를 활용 할 수 있는 방안을 제 7차교과서의 내용을 중심으로 탐색하여 구체적인 예를 들어 교수 ${\cdot}$ 학습활동에 도움을 주고자 한다.

The purpose of this study is to rethink the importance of manipulative materials and to extract of manipulative materials program and its application methods. Activity, construction, and operation is stressed in the elementary mathematics. For this, various technological tools and manipulative materials is emphasized in mathematics teaching-learning methods. Applications of manipulative materials in the elementary mathematics is gradually increased together with curriculum revisions and textbook developments. As a result, tangram, geo-board etc., many tools ate introduces to school mathematics. This study is executed in this contexts. To achieve this, We introduce Australian 'Maths With Attitude' program. This program is composed of the primary level and secondary level. Each level consists of four domains - Number & Computation, Space & Logic, Chance & Measurement, Pattern & Algebra -, and each domains is made up of 20 tasks(i.e. manipulative materials) and programs. This study takes the focus to 5-6 grades programs in the mid of the primary level. First, We introduce 'Monkeys & Bananas'(Number & Computation) and 'Triangles & Colours' (Pattern & Algebra) tasks, and investigate the examples of lessons using these tasks. Second, We think the probability of these tasks' application and draw examples in the elementary mathematic textbooks. Through this works, We respect teaching-learning methods is rich and various in the elementary mathematics lessons.

저학년 학생에게도 적절한 표상이 제공되기만 하면 고등 지식을 수용할 수 있다는 사실은 브루너(J.S. Bruner)의 EIS 이론에 의하여 뒷받침 될 수 있다. 이를 위해서는 구체적인 조작이나 시각적인 표상이 제공되어야 한다. 그러나, 실물로써 교구를 제시하는 것은 현실적으로 많은 제약이 따르므로 그 대안으로 컴퓨터 환경에서 제공되는 조작 도구들을 고려해 볼 수 있다. 인터넷 환경은 접근에 있어 용이하며 별도의 비용이 필요 없고 업데이트가 용이하다는 장점을 가지고 있으므로 교구로써의 장점을 갖고 있다. 이에 따라 인터넷 상의 조작 도구를 통한 수학교육 프로그램을 개발하고자 한다.

The purpose of this study is to compare and analyze the effects of physical manipulative and exploratory geometry software on the spatial sense for 5^th grade elementary school students in learning nets. For this purpose, ton experimental group used Geofix, an operational learning tool, and the experimental group used Cabri 3D, an exploratory geometry software to learn the nets of solids. The comparison group was learned by worksheet only without any manipulative or software. Spatial sense tests were conducted before and after to determine the level, and eye tracking were used to analyze the strategies of students in solving nets problems. As a result, it was confirmed that the using Geofix group was the most effective for the spatial sense, and Cabri 3D could also be a good tool for learning the nets of solids. In addition, after learning the nets of solids, the analytical strategy, which was the most effective strategy for students' solving strategies, increased. In the process of solving spatial tasks such as the spatial sense tasks, eye tracking technology become a very useful tool for exploring students' strategies, so it is expected that objective and useful data will be collected through more active use in the future.

In this paper, we investigated the effects of mathematics classes using play-action programs in the course of mathematics education of future elementary school teachers. This study was conducted with 43 junior university students who selected 'Play Mathematics' in 2006. All the participants in this course was divided 11 groups. Play-action mathematics programs was consisted of 12 themes. For example, there was tangram, somacube, hexamino, tessellation, geoboard etc. In the beginning of lessons, we investigated theses themes itself through plays, puzzles, games, and computer programs. And next time, we investigated the relationships between these themes and elementary mathematic textbooks(i.e. mathematical contents). In 14th and 15th lessons, all the groups took a project presentation lessons that included all things about play mathematics in all group categories. And they developed two themes of play mathematics in accordance with grades, contents, levels as course tasks. Through this study, three educational effects induced. First, future elementary school teachers have a deep understanding about play-action mathematics. They are interested in these play themes, and take part in these play mathematics programs of their own accord. And they realize that these play themes are related to elementary mathematics. Second, future elementary school teachers' attitude and mind about mathematical are improved after this course. Third, future elementary school teachers comprehend various instruction methods relating to play mathematics. Therefore, we suggest that future elementary school teachers need to have many opportunity to experience and develop a mathematics classes using play mathematics.

It is generally accepted that fostering creative thinking is a core in mathematics education and accumulating research products on that topic is really needed. In this study, I hoped to investigate and verify that in mathematics education it was possible to cultivate creative thinking through various and divergent activities, For this purpose, I delat with some illustrations, in which students learned mathematics through the operational activities using teaching tools, problem solving and problem posing activities, and finally they seemed to foster creative mathematical thinking. In conclusion of this paper, I have suggested that in math education those activities should be used to cultivate students' creative thinking in kindergarten or early elementary school. Also I asserted that it is urgently need to store up research products about various materials and methods for those mathematics teaching and learning.
