||Recently, the information and communication technologies change the style of a community, so online community is created. The population of the Internet raised extremely, the network community forms and evolves in different domains, such as commercial, government, medical, and learning. Many different styles of network communities are displayed on the Internet, but the basic format of a network community, especially a network learning community, is still unclear. In 1998, a group of researchers in Taiwan were attempting to construct a network learning community, named “EduCities”. According to the experiences of building the network learning community, the researchers found that a structured network learning community architecture is helpful to support participants in coordinating, managing, and interacting during learning processes. In this work, the EduCities website development background was described, firstly. The author also described ten basic elements include participants, shared visions, devices, services, rules, relations, manners, learning domains, learning goals, and learning activities, which to construct a structured network learning community. Based on the structured network learning community concept, the structured network learning community system, “EduCities”, was implemented and practiced. On the EduCities, many structural designs, such as EduCity, EduTown, EduVillage, EduCitizen, and EduHome were practiced. People in the EduCities play their roles, managing power, learning goals, and social relations. The system design and implementation methods are also introduced in this paper. The system data censuses include growth of the system, frequently visited EduX layers, daily page views analysis, EduTown layers analysis on each county in Taiwan, interviews, and questionnaires, indicate that the structured network learning community is accepted by people. Discussions about structural network learning community design is benefic to learners, separate the online social designers and the online users, supply-deliver-analysis circle, hybrid physical and network learning environments, and migration effect of structured network learning community, were also displayed in this paper. The system statistics and discussions showed that a structured network learning community is easier to support users to interact with others.|
