In the past, autobiographical writing was often used in teacher education courses simply as a way to identify the concerns of pre-service teachers, to bring those concerns forward so that they might better be addressed. Increasingly, teacher educators have recognized the importance of the individual's lived experience as relevant to the development of what he or she will bring to the classroom. Thus, the life histories of teachers have come to be seen as grounded experience for knowledge of teaching. Teacher educators across the disciplines have called for autobiographical writing as a way for prospective teachers to increase their teaching knowledge base, to make explicit for themselves knowledge about teaching and learning--as they have experienced it. The thinking is that if those who would teach can develop a critical distance from their own lived experiences with the content and skills of their subject, they can, perhaps, better assist their students in the mastery of their discipline.
