CITE, HKU has launched a series of research and development projects called 'Learning Community Projects' since 2001. The aim of these projects is to support and investigate the development of life-long learning abilities in group collaborative learning contexts using technology, focusing on finding the relationships between the development of enquiry and knowledge-building abilities and the changing group dynamics and interaction patterns of the learners. The project integrates a web discussion platform called 'Knowledge Forum' (KF) into secondary school curriculum, this project hopes to develop better thinking, analytical and problem-solving skills of students, and to enhance their knowledge-building ability. The various phases of this series of projects until 2008 can be found from the projects page from September 2008. The KB Online Course has summarized valuable knowledge from these earlier projects. From September 2008, the project has extended its scope to become the Professional Network for Knowledge Building in Schools.
