The purpose of this study is to find out how to use dynamic geometry software such as the Geometer's Sketchpad in elementary math classroom. Fist of all, I reviewed dynamic geometry software's property. Then I considered methods to improve geometry education using this software. Some researchers proposed three types of using the software. But I think using the software and developing instructional materials is different. So, I proposed two types of developing instructional materials using the software and two representative examples.

Math teachers are very short of computer tools and manipulatives to use in geometry classes of middle schools for the development of spatial abilities. At most they can ask student to make regular polyhedrons for helping the students to understand by concrete experience, but this experience is not enough to develop spatial abilities in spatial figures including the regular polyhedrons. This article is to introduce instructional materials for development of spatical ability in the regular polyhedrons using computer software, Geometer's Sketchpad. In this article, students can imagine the whole figure through the parts of a plane figure and think of the parts from the solid figure by free movement from 2 dimensions to 3 dimensions, or from 3 dimensions to 2 dimensions. Also, the instructional materials devised in this article will be good to enhance spatial abilities because the relation of 1-1 correspondence in the movement of the parts can be conserved and observed precisely, which is very hard to demonstrate and visualize by paper-and-pencil. It is recommended that this kind of materials should be developed in various ways for teachers to use them directly in their geometry classes.

There is now a large body of research which investigate the preconceptions held by the students in a variety of school levels ranging from the elementary schools to the universities. A problem exists, however, in applying the fingings of the research to the practices of science education. Meanwhile the field of science education is in urgent need of the new instructional theories. One viable means of improving such problematic situation as this is to develop the teaching/learning materials which incorporate the suggestions implied by the results of the research. A prosedure for developing an instructional material and the application of the material in the naturalistic classes are described. Also described in this article are the analyses of the effectiveness of the materials and the implications of this developmental study for the teaching strategies of science.

In response to epoch-making development in science and technology, the innovative curricular materials have been begun to develop since the late 1950s and early 1960s. However, the new inquiry-centered materials have failed to be successfully used in teaching/learning practices of science. Among the various reasons for the failure, the very nature of the inquiry approach has been identified as the most critical problem. Nevertheless, fostering inquiry faculties on the part of the students has been emphasized as one of the most important objectives of science instruction. Therefore this study was conducted for the purpose of developing a practical inquiry-oriented instructional method. In order to obtain this goal the nature of scientific inquiry was analyzed and the status quo of science education in which inquiry-oriented instructional strategies were applied was examined. The results of the study are described in this paper.

본 논문은 2007년 개정 수학과 교육과정에서 제시된 평면도형 내용을 바탕으로, 교과용 도서에 제시된 평면도형의 지도내용과 지도방법을 분석하였다. 구체적으로 수학교과서에 제시된 평면도형의 전반적인 지도흐름을 분석함으로써 교육과정의 기본적인 취지를 어떻게 구현하는지 살펴보고, 도형지도에서 중요한 개념정의와 관련하여 교과서의 ‘약속하기’와 수학적 정의를 비교분석하였으며, 평면도형의 지도방법에 따라 교과서와 익힘책의 관련 내용을 면밀하게 분석하였다. 이를 통해 평면도형과 관련된 교과용도서 개발에 기초적인 자료 및 시사점을 제공하고자 한다.

This paper aims to introduce some useful multimedia freewares, and also support Chinese instructor with discussing how to operate them for instructional design of multimedia language learning class. For this aims, this paper consists of three parts: First, instructional design. This part is focused to what kind of instructional model to be based on, for example, Dick & Carey model, ADDIE model, ASSURE model etc. This part introduces these models, and modifies ADDIE and ASSURE model to D.D.A.I.E.S and S.S.A.U.R.E.S as 'A(nalysis)' in these model may apply to the next 'D(evelopment)' on ADDIE, 'S(elect Methods, Media and Materials)' on ASSURE in the practical Chinese class. Second, Programme: What to use. This part is focused to what kind of free software we can use. In the web site online, there are huge free softwares so we usually hesitate to select and also don't know how to operate even though selected one of them. This part, accordingly, introduces ten of useful freewares and compares each other in terms of usefulness for Chinese instructors. Third, Programme: How to use. It is of no use just to know what to use but not to know how to operate, so this part describes how to use freewares like a kind of manual in detail as far as possible. In conclusion, we hope more Chinese instructors to learn and use more useful freewares for designing the better multimedia Chinese class by this paper.

영재들이 가지고 있는 잠재력이 최대한 계발될 수 있으려면 그들의 특성에 맞는 교육이 제공되어야 한다. 이에 따라, 영재들의 잠재적인 지적 능력을 학문적이고 전문적이며 성숙된 성취 수준으로 구현시킬 수 있는 영재 교육과정을 개발하고, 이를 기초로 하여 교육과정의 내용과 성격을 잘 구현할 수 있는 교수-학습 자료의 개발이 필요하다. 본 연구에서는 초${\cdot}$중등 영재들을 대상으로 하는 영재 교수-학습 자료를 개발하기 위해 영재 교수-학습과 관련된 다양한 이론적 모형들을 종합적으로 검토하여 영재 교수-학습 모형을 구축하였다. 이러한 영재 교수-학습 모형은 영재를 위한 교육과정 중 심화학습에 적절하다. 본 연구에서는 이 모형을 적용하여 초${\cdot}$중등 자료를 개발하였고, 영재 심화 교수-학습 자료 모형의 활용방안과 영재 교수-학습 자료를 통해 영재교육이 보다 성공적으로 우리 교육에 정착되기 위해서 고려해야할 점을 제시하였다.

공간능력 향상을 꾀하는 학교현장에서 도구로써 사용할 수 있는 교구의 효과를 파악하는 것은 현장의 수업을 안내하기 위해 필요하다. 학생의 공간능력을 향상시키기 위한 수업의 구성을 위해 우선 학습 자료와 검사지의 개발 필요성이 제기되었다. 공간능력에 관련된 선행연구를 바탕으로 교구를 활용하는 5차시의 귀납적 수입모형과 공간능력의 하위요소인 공간시각화와 공간방향화에 각각 10문항, 15문항으로 모두 25문항의 검사지가 고안되었다. 경기도에 위치한 중학교에서 중간고사 성적이 동질집단인 4개 반 152명을 대상으로 연구를 수행하여 얻은 자료를 바탕으로 평가문항에 대한 난이도, 변별도, 신뢰도가 조사되었고, 개발된 학습자료의 수정과 보완이 이루어졌다. 차후 공간능력을 다루는 후속연구소에서 그들의 연구목적에 따라 한층 수정 보완된 문항개발이 더욱 다양하게 이루어지길 기대한다.

The purpose of this study was to identify factors that influenced elementary school teachers in choosing websites that support science teaching and learning. The participants of this study were four elementary school teachers. The data was collected through semi-constructed and in-depth interview. The results of the research are as follows: First, the individual factors that influenced participants to choose a website were teacher's thinking about appropriate science teaching and learning methods and teacher's lack of ability to prepare science lessons. Second, the surroundings factors were the image of the teachers using the website, the formation of consensus, belonging to the peer teachers, and students' preferences and interests. Third, participants chose a website where they could provide ideas for science lessons that are not available in textbooks and instructional materials for all subjects, and see stories and tips related to teaching career. In addition, the website was selected according to whether the developer of science instructional materials was a teacher, whether the materials uploaded on the website were up-to-date, and whether the teachers can learn by themselves to prepare for the science class. Fourth, participants considered the design and interactivity of the website and chose a website that is easy to search for information. Finally, we suggested the implications for building the websites that support science teaching and learning.
