This paper discusses the implications of using life history methodology in teacher research. By examining teachers’ life stories within a cultural and historical context the researcher and teacher, in collaboration, construct a life history. Biographical material based on the personal and professional aspects of being a teacher were collected from eight Montessori teachers in Sweden. Empirical data included interviews, diaries, written narratives and discussions. Theoretical and philosophical issues raised in conjunction with the biographies included counterconcepts such as traditional educational theory/critical reflection and continuity/change within the profession. Specific issues were raised in regard to students, parents, the work situation, etc. Valuable insights were gained concerning the changing roles of teachers in contemporary educational contexts. The voices and visions of teachers should thus be able to contribute to a deeper understanding of the role of the teacher and by so doing lead to improvements within the profession as a whole.
