While we are in the midst of a renaissance of interest in augmented reality (AR), there remain a small number of application domains which have seen significant development. Education is a domain that often drives innovation with emerging technologies. One particular subject which benefits from additional visualization capabilities is physics. In this paper, we present the results of a series of interviews with secondary school teachers about their experience with AR and the features which would be most beneficial to them from a pedagogical perspective. To gather meaningful information, a prototype application was developed and presented to the teachers. Based on the feedback collected from the teachers, we present a set of design recommendations for AR physics education tools, as well as other useful collects comments.
