We discuss the development of an instructional design model, WisCom (Wisdom Communities), based on socio-constructivist and sociocultural learning philosophies and distance education principles for the development of online wisdom communities, and the application and evaluation of the model in an online graduate course in the USA. The WisCom model aims to facilitate transformational learning by fostering the development of a wisdom community, knowledge innovation, and mentoring and learner support in an online learning environment, based on a "Cycle of Inquiry" module design, and a "Spiral of Inquiry" program design. Extending beyond current instructional design practice, WisCom provides both a new model for teaching that builds upon the inherent capacity of networked communication to support the growth and intellectual development of communities of practice, and a new model of learning where learners engage in the process of scholarly inquiry that supports individual and collective learning. Evaluation and research data support the WisCom model's ability to design a learning community engaged in the collaborative construction of knowledge. (Contains 2 figures.)
