To date, there has been a very limited application of self-study in coaching contexts.

This paper documents the researchers’ own experiences of learning to coach within a collaborative self-study. The coaches focused on developing an athlete-centred coaching approach. This paper illustrates how self-study supported collaboration, reflection, and pedagogical innovation over the course of a Gaelic football season.
