This paper reports on a study aimed to better understand teaching and learning in an online learning environment through the development of a learning community to facilitate successful learning experiences. To achieve this aim, a qualitative interpretive methodology was adopted to case study an online lecturer and his 14 students’ experiences in a semester long fully online asynchronous graduate course in a New Zealand tertiary institution. Based on the findings, a model for understanding and developing an online learning community for adult tertiary learners is proposed. In accord with sociocultural views of learning and practices, the model depicts successful online learning as a mediated, situated, distributed, goal-directed and participatory activity within a socially and culturally determined learning community. The model informs our understanding of appropriate conditions for the development of online learning communities and has implications for the design and facilitation of learning in such contexts
