This article is based on a project in which a teacher educator, acting as a critical friend, worked with six engineering teachers in a Masters program in Machine Engineering in order to stimulate their reflection on their own teaching and learning as a way of developing their scholarship of teaching. The article draws particular attention to ways of expressing the learning from self-study in order to illuminate the complexities of teaching and to begin to encourage the articulation of the scholarship of teaching as a consequence of a collaborative experience. The results highlight how making teaching visible through the use of self-study offers new ways to capture the complexity of practice, which in this article is considered to be an important aspect of developing the scholarship of teaching.
