摘要:The use of Web services on the World Wide Web is expanding rapidly as the need for application-to-application communication and interoperability grows. These services provide a standard means of communication among different software applications involved in presenting dynamic context-driven information to the user. On the other hand, building a learning community is a collaborative process that necessitates an artful mix of direction and facilitation requiring more than just technology. Collaborative learning communities go beyond just online discussions - they represent purposeful groups focused on advancing knowledge, elevating personal and organizational effectiveness, and generating tangible results. Beyond traditional features like online discussions, instant messaging, document management, and searchable member profiles, the next generation web-based learning community environments should provide powerful tools for facilitating meaningful and productive interactions between members. Recently, there are a number of efforts aiming to investigate whether web services can provide the essential infrastructure for the design and development of next generation learning communities supporting environments. The Special Theme of this Learning Technology Newsletter issue aims to collect early research opinions and development reports on the application of Web Service Technologies in the area of Online Learning Communities.
