This scoping literature review describes the landscape of recent publications (2007-2016) about how teachers and doctors learn through social media to identify whether learning was being considered and, if so, how evidence was collected (N=162). Sixty-seven percent (N=108) were teacher-related and thirty-three percent (N=54) doctor-related, covering empirical studies, literature reviews, position articles and letters to academic journals. Empirical studies were dominant – ninety-one percent (N=98) of teacher-related and sixty-one percent (N=33) of doctor-related – with both fields dominated by in-course evaluations and use/attitude studies. Although doctor-related articles focused on professional online behaviour, rather than professional learning, conference communication and information evaluation were interesting areas of enquiry. Despite professional interest in social media in these professions, there is a dearth of academic studies about their benefits for teacher and doctor learning
