The Magnet Methodology is not the recording of knowledge, skills, techniques, and other information from the past, but creating a knowledge base using present issues of problems for students' and teachers' life-span development through the exploration of career choices and development. In short, it is the multi-cooperative information system for commensalism. It is the magnet program that connects various level of educational institutions under a certain theme and enables students to choose on their own. And this magnet program is being adminstered by the magnet school. And some regular schools provide magnet program as vocational educations and extra-curricular activities. Magnet program reflects the concept of desegregation which was proposed by the U.S. Federal Court decision against the racial conflict which had culminated in the 60s and 70s. Magnet program enables students to choose their own programs and schools, and gives teachers and students the opportunities to develop their teaching method and learning method. That's why magnet program is called continuous, future-oriented one. Teachers and students can also get fair judgement on their activities due to the voluntary magnet program. It mainly deals with practical issues, so it is very realistic to establish the multi cooperative information system including companies, homes, communities, or governments under these practical issues. The openness of magnet program is guaranteed not only by the characteristics of the program but also by the physical layout of the magnet schools. There are no doors and walls, and classrooms are facing one another and sharing all the opinions and information. This precisely corresponds to the concept of co-existence of eco-system and the interdisciplinary approach which is essential to solve our problems.
