The emergence of mobile technologies has changed the higher education landscape. The expansion of mobile technologies in our classrooms presents new learning opportunities not just for students but also for teachers. While professional development is core business for higher education providers, over the years, increasing attention has been afforded to the growing cohort of casual teachers typically overlooked. Sessional teachers are at the interface of learning, yet have historically experienced limited professional development. A unique opportunity is presented to utilize the flexibly of mobile technologies with the needs of time-poor, provisional sessional teachers. This chapter explores this notion and what this might look like by offering two exemplary cases. These cases demonstrate ways in which to use the affordances of mobile technologies to deliver and customize professional development, thereby embedding professional learning in practice. This is an important strategic, pedagogical, and capacity building movement that currently seems to be lacking in uptake and explication of best practice.
