A necessary skill that underpins all professional practice is noticing that which is salient. Noticing can be learned directly and indirectly through a variety of campus-based and placement activities. This paper suggests that developing a capacity for noticing is under conceptualised and underdeveloped in courses preparing students for the professions. It discusses three aspects of noticing: noticing in context, noticing of significance and noticing learning, and explores the use of these through a case study of simulation in nursing education. The case study points to the importance of close attention to the circumstances in which noticing can be fostered and, in doing so, points toward the potential of developing a pedagogy of professional noticing.
