The purpose of this study was threefold: (1) to select the components of spatial ability that could be associated with the implementation of a polycube task, embody the selected components of spatial ability as learning elements and develop the prototype of polycube teaching-learning materials applicable to gifted education, (2) to make a close analysis of the development process of the teaching-learning materials to ensure the applicability of the prototype, (3) to give some suggestions on the development of teaching-learning materials geared toward mathematically gifted classes. The findings of the study were as follows: As for the first purpose of the study, relevant literature was reviewed to make an accurate definition of spatial ability, on which there wasn't yet any clear-cut explanation, and to find out what made up spatial ability. After 13 components of spatial ability that were linked to a polycube task were selected, the prototype of teaching-learning materials for gifted education in mathematics was developed by including nine components in consideration of children's grade and level. Concerning the second purpose of the study, materials for teachers and students were separately developed based on the prototype, and the materials were modified and finalized in light of when selected students exerted their spatial ability well or didn't in case of utilizing the developed materials in class. And then the materials were finalized after being finetuned two times by regulating the learning type, sequence and degree of learning difficulty. Regarding the third purpose of the study, the polycube task performed in this study might not be generalizable, but there are seven suggestions on the development process of teaching-learning materials.

In recent years, parents of students and government have been taking a growing interest in education for the gifted students and there are many research reports about the gifted education. Most of the reports, however, focuses on the conceptional feature of the gifted education program such as organization, operation, management, evaluation, etc,. In other words, there are very few researches on instructional materials for gifted students even though the materials is a critical factor for successful education programs. So, this paper introduces a lecture notes used in a personal education for gifted students to contribute in developing education contents in computer science area. The instructional materials titled as "The Necessity and Application of Matrix in Computer Science" is based on linear equation to usher the students into creative problem recognition and groping for solutions. Also, the instructional materials is useful for students to understand the tight mathematics-computer science relationship and the basic concept of liner algebra.

In this study, learning materials that can be applied for web-based distant learning model were developed based on the characteristics of elementary school science in which investigation skills and thinking ability are considered to be important. And the effect of students' activity in a discussion room on student's investigating and thinking ability was investigated. Through very active on-line discussion, students showed their ability to come up with new ideas and to design and implement diverse experimental methods. Especially, since all of the study tasks given to the students were aimed to utilize experimental means and tools that are so common in everyday life, shortfalls that might reside in the web-based distant learning program could be overcome and students' investigative activity might be stimulated.

The purpose of this study is to find new material for developing teaching and learning materials for the gifted class of elementary school students by using the rotatable tangram made by modifying the traditional tangram. Rotatable tangram can be justified by gifted students through mathematical communication. However, even gifted class students have some limitations in finding and justifying triangles and rectangles of all sizes unless they go through the 'symbolization' stage at the elementary school level. Therefore, students who need an inquiry process for letters and symbols need to provide supplementary learning materials and additional questions. It is expected that the material of rotatable tangram for the development of teaching and learning materials for elementary school gifted students will contribute to the development of mathematical reasoning and mathematical communication ability.

영재교육은 영재들이 창의적인 지식 생산자로서의 역할을 수행할 수 있도록 하여 개인의 잠재력을 최대한 계발시켜주어 자아실현을 도모할 수 있도록 해주고 더 나아가 국가 경쟁력을 높일 수 있으므로 학교와 지역사회에서는 영재교육의 활성화를 위하여 다양한 영재교육 프로그램을 개발하고, 영재에게 적합한 교수-학습 자료를 마련하여 그들의 흥미와 빠른 학습 속도를 충족시켜줄 수 있도록 심화된 학습 기회를 제공하기 위해 노력해야 한다. 그러나, 이미 연구된 자료들을 살펴보면 초등학교 고학년을 위주로 하는 영재 교육 프로그램이 대부분이어서 저학년 영재아동을 위한 자료는 전무한 실정이다. 따라서 본 연구에서는 초등학교 저학년 단계에서 수학분야에 영재성이 있거나 흥미를 가지고 있는 아동을 위한 수학 심화학습 프로그램을 개발하고자 한다.

현재 우리 나라에서는 과학영재교육원을 설립하여 초 ${\cdot}$ 중학생을 대상으로 영재 교육 프로그램을 운영하고 있다. 하지만 실제 초등학생보다는 중학생에 초점을 두고 이루어지고 있으며 프로그램의 내용 역시 일반화되어 있지 못하다. 특히 영재교육진흥법과 시행령이 통과되어 올해부터 영재 학교 ${\cdot}$ 학급이 운영되고 있는 현시점에서 영재들을 교육시킬 교수 ${\cdot}$ 학습자료의 개발이 절실히 요구되고 있다. 따라서 문제해결력중심, 수학실험중심, 수학탐구중심이면서 수학분야에 흥미가 있고 재능이 있는 아동들에게 수학적인 힘을 강화하고 자발적인 학습 태도를 배양시킬 수 있는 초등학교 중학년 영재아들을 위한 학습자료를 개발하는데 이 연구의 목적이 있다.
