Online learning is a key feature of the contemporary educational landscape and has entered mainstream policy, provision and practice. But if online education is to reach mature development and evaluation, it must be open to critical appraisal. This book considers the implementation of online learning within adult theological education. This can be an area of challenge or contention, especially when established academic practices and cherished values are seen as threatened when handed over to online delivery. This opens questions about theology, pedagogy and online education. Does online teaching and learning bring or demand a new or transformed (disruptive) pedagogy or does it result in maintenance or replication (sustaining) of traditional values and existing practices? What might the opportunities and benefits be? Who stands to gain? Who stands to lose? And what evidence is there to evaluate the quality of 'doing theology' online? This book examines a long-standing programme of continuing professional development delivered fully online to adult practitioners working across Christian education and ministry settings. It builds upon the author's international experience as an online educator for over a decade. Key themes relate adult learning to theological pedagogy, authority, and online community. The concept of interruptive pedagogy is presented as an interpretative model to critically appraise an approach to online education that draws on the best theological tradition yet also looks to the future.
