Knowledge based social networks are regarded as valuable learning tools, particularly in their ability to promote collaborative learning, and high level of adaptability. This research-in-progress investigates key factors in the design of a Wiki-based knowledge sharing tool to support teaching and learning in a third level institution. To determine these factors, five higher education institutions were selected and within these institutions, a number of individuals were selected for interview, based on their extensive experience with technology-supported learning and collaboration. This paper develops a development model for a knowledge community and proposes key development decisions that should be taken into account, such as pedagogy, technology, and the integration of these two core areas to provide a holistic learning experience. The paper concludes with a plan for the creation and evaluation of a knowledge base for a learning community.
