The purpose of this study is to develop Project-Based Teaching-Learning materials for mathematically gifted students using a Fermat Point and apply the developed educational materials to practical classes, analyze, revise and correct them in order to make the materials be used in the field. I reached the conclusions as follows. First, Fermat Point is a good learning materials for mathematically gifted students. Second, when the students first meet the challenge of solving a problem, they observed, analyzed and speculated it with their prior knowledge. Third, students thought deductively and analogically in the process of drawing a conclusion based on observation. Fourth, students thought critically in the process of refuting the speculation. From the result of this study, the following suggestions can be supported. First, it is necessary to develop Teaching-Learning materials sustainedly for mathematically gifted students. Second, there needs a valuation criteria to analyze how learning materials were contributed to increase the mathematical ability. Third, there needs a follow up study about what characteristics of gifted students appeared.

In this paper we have developed metadata system in order to utilize and refer to ICT educational resources which stand on the basis of standard international metadata " DC Core Education" by analyzing into the time input resources during each lessons. This metadata system makes addition metadata elements(introduction, development, review) in the flow of a general lesson to many ICT educational resources and high quality educational information in the web. It means elementary school teachers feel easy and convenient by offering systematically interface and unify reference. The system could expect to willing to help effectively lessons with ICT.

This study is to search the problems of schoolyard teaching material developed by pre-service earth science teachers and the critical factors affecting material making. The 258 schoolyard teaching materials was collected from 54 pre-service earth science teachers (male: 18, female: 36) major in Earth Science Education in Jeonju, Korea. The schoolyard teaching materials was greatly influenced by making process type of it and the prior knowledge of pre-service earth science teachers. As schoolyard preference exploratory type rely on their prior knowledge to develop the schoolyard teaching materials, they made use of the limited concepts like fault in material making. But the concept preference exploratory type made use of concepts not accessible to majority of pre-service earth science teachers because they selected a concept from the earth science textbook first of all. The pre-service earth science teachers having wrong prior knowledge selected inappropriate resources, as well as fell into the error of concept connecting. The pre-service earth science teachers having right prior knowledge partly considered only shape of resources, but had a disregard for formation process of it in material making. Accordingly, we need to reflect richly Geological Field Trip and Solid Earth Science to curriculum for earth science teacher education. And we have to educate pre-service earth science teachers to create holistic concept on the geological subject matter knowledge, field based teaching and learning strategy, material making process.

A knowledge-based society values creative and independent individuals. This study depicts operational approaches to the effective utilization of school libraries as teaching/learning media center in order to support independent learning in relation to the way in which constructivist teaching-learning(CTL) improves learners' self-learning abilities. The result of this study seems to imply that self-learning based on constructivism is possible only when school libraries are managed as teaching/learning media centers and that the more variety there is in learning materials and when more direct interaction exists, there is more creativity and self-learning abilities are achieved in the learning process.

The purpose of this research was to develop and analyze the effects of ICT based teaching learning process plans for 'Designing My Home' unit of Technology Home Economics subject in High School. The seven housing contents were selected from 8 textbooks and 8 teaching resources at the analyses stage. A specific homepage(ieduhome.cafe.com) was built to utilize the eight ICT teaching learning process plan as well as many other resources at the planning & development stages. The number of 68 highschool students have participated for the application stage during September 4-26, 2003 and the same number have studied the same contents through regular teaching learning plans as a comparison group. Experimental groups have significantly more increased in the knowledge and understanding of the housing contents than have comparison groups. The same results occurred in the interests in Home Economics, Housing, and Internet utilized study. The Design reports were not statistically differed between two groups based on the objective evaluation criteria. The results of this study generally supported previous research and showed that the In teaching learning plans were more effective in various aspects than were the regular plans.

In this study, we carried out a case study with 38 pre-service mathematics teachers. A theoretical basis of this study is the 'technology principle' by NCTM(2000) and teaching-learning methods by the 7th curriculum. Using mathematics program(Grafeq.), we executed classroom activities for developing materials assisting teaching-teaming for 7th-9th grade mathematics. Pre-service mathematics teachers constructed mathematical designs for each grade by Grafeq. program. We tried to find the results for three research problems. On the basis of observation data, interview data and document materials, we analysed our results as follows. First, our activities help Pre-service mathematics teachers to examine and understand each grade mathematics. Second, we can developamathematicaldesignineachgrade mathematics. Therefore mathematical designs developed in this study can be used middle school mathematics classroom. Third, pre-service mathematics teachers gained the belief that the activities using mathematical in this study can be applied program. effectively to teaching and loaming school mathematics.

The purpose of this study was to develop ICT(Information and Communication Technology) teaching-learning materials for motorcycle safety education. Physical subjects which are relevant with motorcycle dynamics were introduced to increase the safety awareness through integrated learning such as the combination of technology and science. The results of this study were as follows : (1) Utilizing the physics basic theories which are relevant to motorcycle dynamics, the lesson plan of motorcycle ICT teaching-learning materials, which were included to plan and instruction action plan, was developed. (2) Flash animation or movie was developed to apply physics knowledge to technology in driving motorcycle. This is able to improve the attitude of driving motorcycle of students. (3) Through the contents of appendix of motorcycle safety driving section in this web-site developed here, junior and senior high school students would be able to strengthen their cognitive domain of motorcycle by themselves. (4) Using the web-site of this study, both teachers and students would be able to freely interact through an online bulletin board.

정보화 시대를 맞이하여 정보의 홍수 속에서 지리교사들은 정보 획득 능력에 있어서 큰 차이를 보여주고 있다. 이와 같은 현실에서 정보 접근 능력이 떨어지는 교사를 탓하기보다는 산재해 있는 지리정보를 되도록 한 곳에 통합해서 교사에게 지름길을 제공하는 것이 더욱 효율적인 방안이 될 것이다. 대부분의 지리 교수-학습 자료가 전적으로 자료를 개발한 사람의 의지에 따라 만들어진 자료이기 때문에, 다른 지리교사가 사용할 경우 융통성이 부족하므로 사용자의 의도에 맞게 수정 편집될 수 있는 형태의 자료가 바람직하다.(중략)

교육 인프라의 구축과 함께, 엄청난 예산을 들인 인프라의 활용을 위한 국가적인 차원의 여러 가지 논의가 이루어졌고 결과적으로 에듀넷과 교수.학습지원센터와 같은 기관들이 탄생되었다. 하지만, 방대한 자료와 훌륭한 운영 체제를 가진 기관이라도 일선 현장에서 실제 교육을 담당하고 있는 교사들 각각의 모든 요구를 만족시키지는 못하고 있다. 교사들 각자가 생각하는 수업시간에 유용한 자료의 기준이 각각 다르고, 자료로의 신속하고 정확한 접근이 웹 상에서는 가끔 어려울 경우가 있으며. 교사들 각자의 자유로운 분류 기준을 만족시키기에는 어려움이 있다. 이에 본 논문에서는 교사들이 자신의 입맛에 맞게 교수.학습 자료를 관리할 수 있는 시스템을 구현하려고 한다.
