This chapter focuses on discussions you hold with a beginning teacher pre- and post-lesson observation. These are integral parts of the observation cycle (see Chapter 13), acting as bookends to the observation of teaching. O’Leary (2014, p. 3) argued that the observation of teaching ‘has commonly been used as a method of assessment and is an important tool for nurturing key pedagogical skills and teacher learning’. Pre- and post-lesson discussions, therefore, provide the opportunity for reflection on what is observed in a lesson.
