This edited volume builds upon the premise that online learning is not separate from the social and material world, and is made up of embodied, socially-meaningful experiences. It is founded on a "postdigital" perspective in which, much more than interactions with keyboards, computer screens, hardware or software, the learning that happens on online postgraduate programmes spills out into professional and informal settings, making connections with what comes before and after any formally-scheduled tasks. Unlike other books relating to online education, this book combines a theoretical perspective, in which the digital, physical and social are all interconnected within complex educational ecologies, with a focus grounded in postgraduate practice. This focus has important implications for the kinds of students and learning that are explored in the chapters of the book. This book provides an important contribution to the knowledge of what is required to produce quality, online postgraduate programmes at the level of teachers, curriculum designers, faculty developers and policy-makers.
