The paper is about the design and management of education in/ around/ through architectural and urban space. It is also about the design and use of school buildings themselves and the city for educational purposes. Following the complex relations in educational design, urban space, and knowledge system, the author claims how a city could be open-ended, multi-value, and critic. In tacking functions of schools, he provides three types of experiencing school, city, and knowledge. He points out that knowledge system limited by the cognition process and social reproduction will determine the spacial levels and school plans in reality. However, that is the key question that we must consider and criticize. Learning is not necessary to limit itself in the labeled school buildings as well as urban spaces. The city that we live everyday supports the richness of education. We could see so many different things in the city. Hence, we understand the world.
