IMPROVISATION AND TEACHER EXPERTISE: A COMPARATIVE CASE STUDY NICHOLAS TREVOR SORENSEN A thesis submitted in partial fulfilment of the requirements of Bath Spa University for the degree of Doctor of Philosophy School of Education: Bath Spa University February 2014 Nicholas Sorensen, 2014 1 Abstract This thesis reports on an enquiry into the nature of teacher expertise which pays particular attention to its improvisatory nature. The study draws on three main areas of literature and theory: critical studies in improvisation; expertise and expert practice and organisation theory. These are used to present a model of teacher expertise that is derived from grounded theory. The data is taken from a series of comparative case studies of seven experienced teachers working in secondary schools in the South West of England and who have been identified as being expert within their school setting. Constant comparative methods of analysis have been used to draw out themes from the data. This has contributed to a grounded theory that identifies the nature of teacher expertise. The findings that arise from the data are that teachers expertise is best expressed as continually evolving practice, a process as opposed to an end state. Advanced professional practice is best described as a teahe ith epetises ad this is pefeale to the te epet teahe. The data shows that teacher expertise is fundamentally improvisatory and that this has a positive impact on the quality of teaching. The improvisation nature of teacher expertise is derived from four processes: the expression of tacit knowledge, relational and interactional practice, personalisation of the learning environment and self- reflection leading to the continual adaptation of pedagogy. The resulting model of teacher expertise casts new light on how we understand advanced professional practice and this has implications for school leaders, teachers, researchers and those with responsibility for the initial training and the continuing professional development of teachers.

To begin with I must thank the wonderful teachers and headteachers who gave so willingly of their time and allowed me to interview and observe them. It was a privilege to have met you and spent time in your company. I must also record my debt to my supervisors who have guided and supported me through this journey. My Director of Studies: Professor Steven J. Coombs; for his encouragement and inspiration which allowed my initial ideas to take flight. I valued the way in which he supported my conceptual thinking and, in particular, I attribute to him the specific contribution of the thee postulates. My External Supervisor: Dr Jill White; for making sure that my feet were on the ground. My Second Supervisor: Emeritus Professor Stephen Ward; for guiding me through the final stages and for his attention to detail. Your wisdom and critical support has been invaluable; a real team effort. I would want to thank all the staff and students at Bath Spa University who have shown an interest in this research, have asked questions, offered support, shared ideas with me and uged e to get the thig opleted. You ae too ueous to mention but you know who you are. And finally I must extend my thanks to my friends and family who have had to cope with my absence, in body and mind, as I have given my attention to my writing.
