Patrick Barmby is a Lecturer in Primary Mathematics at Durham University and is the Programme Director for the BA Primary Education course at Durham. Patrick's area of research is in primary mathematics, with a particular focus on developing children's understanding in maths. He has also carried out research projects on developing teachers' knowledge in primary maths. For him, one of the best parts of teaching on the Primary Education degree at Durham University is not only influencing student teachers' practice in primary maths, but also being influenced himself by the wealth of experiences and expertise from the classroom that students bring to the sessions.
